By the Regulation of Apparatus to Pressure, approved by Royal Decree 1244/1979, of 4 April, all aspects were regulated to take into account in relation to the design, manufacture, repair, modification and inspections periodic of the apparatus under pressure.

The European Economic Community and subsequently the European Union have come to issue implementing directives on certain pressure equipment or apparatus which have amended the Regulation on the Regulations to Pressure adopted in 1979. Royal Decree 473/1988 of 30 March 1988 transposed Directive 76 /767/EEC on pressure equipment, Royal Decree 1495/1991 of 11 October 1991 and Royal Decree 2486/1994 of 23 December 1994, Directives 87 /404/EEC, 90 /488/EEC and 93 /465/EEC on simple pressure vessels; Royal Decree 2549/1994 of 29 December 1994, Directives 75 /324/EEC and 94 /11/EEC on aerosol dispensers; Royal Decree 769/1999 of 7 May 1999, Directive 97 /23/EC on pressure equipment, establishing new criteria for the design, manufacture and assessment of conformity and the Real Decree 222/2001 of 2 March 2001, together with Order CTE/2723/2002 of 28 October and Royal Decree 2097/2004 of 22 October 2004, Directives 1999 /36/EC, 2001 /2/EC and 2002 /50/EC on transportable pressure equipment.

On the other hand, at present, taking into account the experience gained with the implementation of all these regulations, it seems necessary to address the updating and revision of the regulation of pressure equipment.

The time since the publication of the said Regulation of the Apparatus to Pressure, the experience acquired in its application and the new criteria established by the transpositions of the directives, make it necessary update and revise the requirements of that Regulation.

By this royal decree a new regulation is approved laying down the requirements for the installation, commissioning, periodic inspections, repairs and modifications of the pressure equipment, with maximum permissible pressure exceeding 0,5 bar, with the understanding of devices, pressure equipment, assemblies, pipes, simple pressure vessels or transportable pressure vessels. In addition, additional technical instructions for certain equipment or installations are approved. Foreign natural persons who may be directly or indirectly involved in the content of this royal decree must comply with the regulations in force on immigration and immigration, and in particular on development and exercise of business, employment, economic or professional activities.

The regulation now adopted complements the legislation on pressure equipment provided for in Royal Decree 769/1999 of 7 May, which provides for the application of the Directive of the European Parliament and of the European Parliament. Council, 97 /23/EC, relating to pressure equipment and amending Royal Decree 1244/1979 of 4 April 1979, which approved the Regulation of Apparatus to Pressure. The aforementioned royal decree only regulates the requirements for the design, manufacture and certification of the conformity of the pressure equipment.

In the project phase, this royal decree has been submitted to the hearing procedure prescribed in article 24.1.c) of Law 50/1997 of 27 November, of the Government and the autonomous communities have been consulted. It has also been subject to the procedure for information on technical standards and regulations and regulations relating to the information society, which is regulated by Royal Decree 1337/1999 of 31 July, for the purpose of complying with the Directive 98 /34/EC of the European Parliament and of the Council of 22 June, as amended by Directive 98 /48/EC of the European Parliament and of the Council of 20 July. He has also reported favourably on the royal decree of the Industrial Security Coordination Council.

This provision is dictated by the provisions of Article 149.1.13. of the Spanish Constitution, which attributes to the State the competence to determine the bases and coordination of the general planning of the activity. without prejudice to the powers of the autonomous communities in the field of industry.

In this respect, it should be noted that the regulation adopted is of a basic regulation and contains forecasts of a purely and markedly technical nature, and therefore the law is not an appropriate instrument for its establishment and its approval is justified by royal decree.

2.1-Level A and B.

Inspections will be performed annually with the following criteria:

a) General inspection.

A visual inspection of the accessible parts from inside the boiler will be made and the possible deformations of the parts under pressure will be checked. This will remove the deposits and embeds that make it difficult to inspect.

b) Calderines.

Top and bottom calderines will be opened and inspected (if any), checking:

-Existence of punctual corrosions "pitting" inside.

-Existence of sludge, chemical analysis and removal of sludge.

-Interior state of the mouths of the tubes to the Calderines.

-Subject and state of internal fittings.

After inspection the change of affected joints will be mandatory.

c) Solera.

The condition of the refractory of the solera shall be inspected, in the event that there is any repair or replacement of the defective areas.

d) Power collectors.

The feeding collectors shall be inspected with a range similar to that indicated for the Calderines where possible, using the practicable records arranged for this purpose. A mirror, endoscope or any other useful may be used to allow the interior vision of the total collector.

e) Security valves.

They will be totally removed to ensure the perfect condition of all the elements that make up them, as well as to ensure that it is free of moulds, inlays or strange elements that prevent its perfect operation. It shall be checked that the discharge pipe drain is free from any obstruction, to prevent condensate water from being accumulated over the valve and to increase the back pressure thereof.

f) Inspection of blower entry zones.

Each and every curve of the tubes in the blowing step shall be examined to find out the possible formation of cracks in the closing and breaking fins of the welds that attach the tube to the tapes, such as result of the condensate drip due to possible deficiencies in the automatic blower valve. In cases where the eye inspection advises, penetrating liquids or other testing systems shall be used.

The perfect alignment of each blower will be checked in the entirety of its journey.

g) Control of Ultrasound Thicknesses.

The thickness of the tubes shall be measured at the points and percentages indicated:

-At the solera level, if carbon steel tubes are used, 50%. If bimetallic tubes are used, 15%.

If bimetallic tubes are used, 100% of the tubes that make up the air inlet itself and 25% of the straight tubes.

-At the level of black-distance burners, 100% of those that make up the entry itself.

-At the level of secondary air entries, 100% of those that make up the air inlet.

-At two more levels, between primary and secondary air, the percentage will be chosen in each boiler according to the experience and corrosion rates observed.

-At two levels above the secondary air intake, the percentage will be chosen in each boiler, according to the experience and corrosion rates observed.

-In the accessible curvatures of all tubes that are located up to 2 m. above the secondary and/or tertiary air levels, 100%.

-In the curves of the accessible tubes of the tubular beam and at least one point on the straight part thereof, 100%.

-In the accessible curves of the firewall panels, 100%.

-In the lower curves of the recliners, 25%.

-The user must also measure thicknesses in those parts which, either by means of the builder or by their own experience, may be subjected to high corrosion rates.

When a thickness is located in a pipe whose corrosion rate is higher than usual, it will be mandatory to continue measurements along this tube and contiguous to narrow the affected area.

Each user will carry a record of the measured thicknesses, as well as the maximum corrosion rates and trends thereof.

Within a maximum of one year, all sections of tubes whose thickness, depending on the expected corrosion rate according to the trend of that area, will be changed, will compromise the safety of the boiler in the period of two years, the minimum thickness calculated according to the code adopted at the end of that period.

h) Other controls for bimetallic tubes.

ANNEX

Inspections and tests

1. General considerations.

This Annex defines the conditions for carrying out the inspections and testing of the pressure equipment included in this ITC.

Special reference is made to the boiler as the main element of the operation and maintenance of the plants that are the object of this ITC, and the criteria that are set, in whatever form, are extended to the rest of the equipment.

In addition to the instructions and standards set by the manufacturer of the various elements, all the actions referred to in this paragraph shall be construed as inspection and shall in particular be carried out in The instructions are given in the following sections.

2. Inspections.

2.1. Visual inspections.

Consist of the inspection of the boiler and pressure equipment, both on the side of the smoke and on the fluid side, observing the accumulated deposits on their surfaces to detect possible service anomalies and/or operation.

Subsequently to this inspection, removal of all inlays and deposits that may prevent further examination with depth of the parts under pressure shall be carried out.

Once the cleaning is done, another new visual inspection of all the components (economizers, overheating, etc. and partition plates, welds, grubes, fixings, etc.) will be carried out both from the boiler and from the other Pressure elements. The parties which, in the opinion of the inspector, may have an important anomaly, such as deformations, fissures, corrosions, wear and tear, etc., shall be checked by appropriate means.

2.2. Supplementary tests.

When visual inspection and the operating history of the boiler and the pressure equipment are prima facie evidence to suspect that any part, element or component thereof may be defective. important, the additional tests that the inspection officer agrees with the user or the technician designated by the user should be carried out, leaving the tests written.

If the visual inspection and the supplementary tests were to be concluded that any of the parts under pressure are deficient, the repair or replacement of the test parts should be carried out.

2.3. Deformations.

If deformations exceeding the maximum permissible values referred to in the design are detected, repair, replacement or, possibly, the reduction of their maximum service pressure should be carried out, in particular in:

a) homes and their joints to the tubular plates

b) drums and collectors

2.4. Hammers and braces.

Viromers and braces must be replaced with breakage or a decrease in diameter equal to or greater than 2 mm.

2.5. Reinforcement carcloths.

For the total or partial break of a weld cord joining the boiler reinforcement carwebs, prior to repair it will be checked whether, as a result of such breakage, possible cracks have occurred or deformations in the sheets which are the object of the reinforcement or in the tubes, which, if necessary, shall be repaired.

2.6. Welding cords.

All those seams whose weld cords present anomalies will be exceeded. Repair welds must respond to recognized procedures and the specialist welder must be qualified.

2.7. Tubes, tubular plates and collectors.

The possibility of replacing the upholstered tubes and cleaning those with obstructions will be considered. The joints of the tubes shall be checked at the tubular plates, especially at the end of the household box. In the aqueous boilers, the fixing of the tubes to the drums and collectors shall be checked, in particular in the case of joints with points of rigidity.

In the case of boiler tubes in contact with the gases, the cut of a sample of worn tubes, among the most significant, will be subjected to a pressure test in a workshop or replacement, taking the result of the same as representative of the whole area inspected and therefore, if not satisfactory, the appropriate repair will be carried out.

2.8. Measurement of thicknesses.

All points where visual inspection has detected possible corrosions or abnormal wear will be checked. If no thickness defects have been observed in the visual inspection, the check of randomly chosen points will be performed and where there is experience of previous wear and tear.

When the thickness of the material falls below the thickness of the calculation, the user and the inspector of the approved inspection body may agree to replace the material, the repair with a suitable method, as may be the recargüe with welding, or a decrease in the maximum service pressure.

When the inspections carried out show that the actual thickness is less than the initial minus the over-thickness expected by corrosion, or that the presence of discontinuities of magnitude greater than that admitted in the design is present, you must proceed to:

(a) Perform a supporting calculation showing that the actual thickness will be capable of withstanding the maximum service pressure throughout the period of time until the date on which the next step is to be taken inspection.

b) Pressure-proof Someter to the affected element, all with the supervision of an approved control body.

c) If the result is not successful it will be repaired.

2.9. Lamination defects of the sheets located at the thickness check.

The existence of possible lamination sheet defects will be especially checked, using standards of recognized prestige or appropriate procedures.

If, during the measurement of ultrasonic thicknesses, an abnormal decrease in thicknesses is detected at some point or zone of a sheet that has not been observed in the visual inspection, it shall be checked if the thickness is not detected. is punctual or is due to a lamination defect of the veneer (lamination sheets). If the use of ultrasound and visual examination leaves room for doubt as to whether the anomaly found is for lack of thickness or sheet of lamination, a small drill will be carried out and the thickness will be measured directly.

If the defect is found to be laminating, the contour and surface of the sheet shall be determined and, if this is within the limits of a circle of 75 mm in diameter, the defect shall not be taken into account. If, on the other hand, the surface of the sheet exceeds the limit indicated above, but no abnormal deformation is observed, the contour, surface and situation of the same shall be determined, leaving a written record to the back or an annex to the minutes. for inspection and periodic testing, the purpose of which, in successive revisions, may be checked for deformations in the bounded area, in which case the repair of such formations must be carried out.

If during the following inspections, at which a lamination defect has been observed, no deformation is detected in the affected area, the following periodic review shall check the surface of the contour of the the leaf and, if the leaf has increased by more than 20%, the repair of the affected party must be carried out, even if no deformation is observed.

Lamination defects located in sheets of elements under pressure inside shall not be taken into account, except in the areas where there is a weld-bonded reinforcement element.

2.10. Pipelines.

(a) Zones subject to time (turbine and boiler) and trousers:

Conducting magnetic particles and ultrasounds in welds, sampling by metallographic replicas in pipes subjected to slow creep at high temperatures.

b) Pipeline Rest:

In pipes subjected to slow creep at high temperatures (hot and heated main steam), the circumferential welds shall be subjected to inspections by magnetic particles and ultrasounds by 10% and the Longitudinal welds, if any, by 20%. The welding of the accessories (supports, instrumentation, drains, etc.) will be controlled by 20% by magnetic particles.

In pipes that are not subjected to slow creep at high temperatures (cold heated steam, feed water, etc.), welds will be subjected to inspections by magnetic particles and ultrasounds by 10%, while the welding of the accessories shall be controlled by 10% by magnetic particles.

2.11. Security fittings and valves.

Prior cleaning of the accessories, the regulators and water and pressure level limiters, valve, purgators, level indicators, studs, tubers, connection tubes, etc. will be inspected. If there is a flotation chamber, it shall be checked that its interior, as well as the connecting tubes, are clean.

The safety valves will be dismantled to check that their different elements do not fail and that their interior is clean of rust, incrustations or foreign substances. The adjustment, testing and sealing shall be carried out.

The inspection and cleaning of the elements of the safety valves, flotation chambers and accessories can be carried out by the manufacturer or the authorised repairer ERP-2 prior to the visit of the responsible inspector. of the periodic inspection and test. All safety valves must be removed, adjusted correctly, then tested and sealed. In this case, the manufacturer or the repair undertaking shall extend a certificate certifying that the operations indicated have been carried out.

The verification of the operation of the indicated elements, as well as the regulation and sealing of the safety valves, shall be necessarily certified by the inspector of the approved inspection body. In the case of boiler safety valves, these inspections shall, in addition, be carried out in conjunction with the pressure test and, failing this, by means of replacement hydraulic equipment.

2.12. Gauges and thermometers.

All thermometers, pressure gauges and pressure detectors shall be checked and calibrated with a standard element.

3.3. Hydraulic test.

Before filling with water, it will be necessary to verify that the structures and foundations that support the apparatus or system are in a position to resist the load to which they will be subjected, and will be placed blind flanges or plugs threaded, as appropriate, in steam or safety valves.

It will take care that staff stay away during test development, funds, caps, threaded parts, and avoid the presence of people outside the test.

The manometers will be installed outside the vertical projection and will be preferred to position them laterally or in a higher position. During the filling of water, the circuit will be carefully vented to prevent air chambers from remaining.

Due to the high energy stored in the hydraulic test, special precautions shall be taken when the test pressure is greater than 80 bar or if the product of the test pressure (PT) in bar by volume (V) in litres is greater than 10,000.00, for which it is necessary to make a detailed plan of sequence of the same, duration and minimum distance of security.

In any case, the pressure rise will be gradually done up to the test value, with a stay time of no less than 15 minutes after the stability has been achieved. Close visual inspection will not be required for leaks, in this first stage. It will then be reduced to maximum service pressure (Pms) and carefully inspected. The temperature of the metal must not be less than a pre-fixed limit in each case depending on the strength or fragile break of the material.

The temperature of the test fluid must not reach the values that constitute accident hazards for the persons performing the inspection and test.

If fluid leaks are observed during the hydraulic test, the pressure will be lowered and the necessary repairs will be made to remove them, starting the test again.

3.4. Pneumatic test.

In case of not being able to perform the hydraulic pressure test, a pneumatic test may be performed.

For the increased risk of this test, a visual inspection of the equipment must be carried out in advance and taken into account:

a) A detailed plan of the stages of its development should always be made with time to maintain the pressures during each stage, defining also the minimum safety distances.

b) During the development of the test, the zone shall be marked by which the movement of personnel outside the test shall not be permitted.

c) All the above checks must be performed by competent technical personnel of the test performer.

CHAPTER IV

Other Provisions

Article 8. User obligations.

In addition to the obligations set out in Article 9 of the Pressure Equipment Regulation, the user must have:

1. Maintenance.

The user must perform a maintenance that ensures the availability and reliability of all elements of the facilities included in this ITC.

This maintenance will be based on the manufacturer's instructions and on the experience itself, and should be carried out with the required periodicity.

2. Inspection Manual

The user shall have an inspection manual, which shall contain at least the description of the organisation, the number and qualification of the persons to be involved, the detailed inspection procedures and the programme inspections

The inspection program must ensure compliance with regulatory deadlines.

In addition to the periodic inspections indicated in the Pressure Equipment Regulation and in this ITC, it shall be necessary to carry out as many controls, inspections or tests as are necessary to ensure the integrity of the equipment and facilities. In this regard, the indications of the manufacturer of the equipment and the criteria for inspection of the recognised standards or internationally accepted standards in the sector shall be taken into account.

The user must take advantage of scheduled technical stops (general unit stops for maintenance, change of catalysts, market conditions, etc.) or caused by breakdowns, to carry out inspections, checks or tests.

The inspection service of the user shall keep the management of the refinery or the petrochemical plant of the state of the equipment or systems informed, and recommend the putting out of service of those in which it is detected that the required security is not met. The inspection service may not be dependent on production or maintenance.

3. Other controls.

In addition to the checks and inspections that are expressly indicated in this ITC, at least the following controls must be carried out:

a) Corrosion control.

There should be sufficient technical information available for each pressure equipment to know the corrosion margins of the containers and pipes of each system.

The checks must ensure that all parts of the systems are checked, taking into account the different physical-chemical states of the fluids or the geometric factors.

The pipeline inspection program may be based on predictive analysis that controls the residual life of the systems, and controls must be carried out in good time to the exhaustion of the corrosion margins. The analysis should preferably be based on software which controls the evolution of the thicknesses. Similarly, the experience of similar systems may be used.

The possibility of corrosion under isolation or under stress should be taken into account.

b) Control of erosion.

The possible erosion that may occur in the systems due to the characteristics of the fluid and its velocity should be taken into account.

(c) Special controls, depending on the particular characteristics that may be presented by certain equipment or installations. Specific studies identifying the particular risks that may condition the integrity of the pressure equipment should be available.

In this sense, consideration should be given to the possible evolution of the materials according to the operating conditions (structural changes of the materials, slow yield analysis at high temperatures, ...).

ANNEX

Periodic Inspections

In the application of this ITC, the following criteria shall be taken into account in Annex III to the Pressure Equipment Regulation:

1. Inspection Level A (External Inspection in Service).

In addition to the requirements set out in Annex III to the Pressure Equipment Regulation, an ultrasound and/or any non-destructive test shall be carried out as necessary.

2. Inspection Level B (Off-duty internal inspection).

Consist, at least, in a complete internal visual inspection and check of thicknesses of all the parts under pressure. If this inspection results in reasonable grounds for increasing control, the non-destructive tests deemed necessary shall apply.

Where an internal inspection cannot be carried out by physical impossibility or justifiable technical reasons, it shall be replaced by the necessary non-destructive tests which ensure equivalent safety or a test of pressure.

In the case of pipelines, internal inspection will not be required.

3. Inspection Level C (Pressure test).

Empty equipment will not require hydrostatic testing.

4. The following considerations shall be taken into account in carrying out the inspections:

4.1 Test fluid.

For hydrostatic pressure testing, water will normally be used at room temperature. During the test the water temperature shall not be less than 10 ° C.

When the design of the equipment sets the nature, quality and temperature of the test fluid, the pressure tests shall be done in accordance with the requirements, taking all appropriate precautions.

Among others, they are considered to be supporting technical reasons for the change of test fluid or replacement of the following:

a) Reasonable doubts in the structural strength of foundations or foundations.

b) Harmful Effect of fluid on internal elements or apparatus walls.

c) Circuit drying, drain, or vent difficulties.

d) Material difficulty to perform hydrostatic test.

4.2 Test Pressure.

(a) The value of the test pressure (Pp) shall be that indicated by the manufacturer of the equipment, or in the absence of the hydrostatic manufacturing test, not exceeding 90 per cent of the elastic limit of the material to the Test temperature for primary membrane efforts.

As an exception, any reduction in the test pressure values shall be approved by the competent authority of the autonomous community, after technical justification and with the favourable report of a control body.

(b) In the case of vacuum equipment, special attention must be paid to the tightness of the equipment, so that when a level B inspection is carried out, a proof of tightness must be carried out before it is put in place. service. Vacuum equipment containing non-combustible fluids or non-formers of explosive mixtures is exempt from these tests.

To equipment operating under conditions of use under which experience shows that no internal corrosion problems arise, the following requirements shall apply to them:

-The equipment shall be subjected to the first hydrostatic pressure test, being exempted from the following periodic tests of level B and C, except that for other causes they have to be put out of service for repair. In this case visual inspection of the repaired area shall be carried out and shall be subjected to a pressure test.

-In any case the inspectors themselves will do regular level A inspections, in order to know the status of the areas where there can be external corrosion and where the greatest efforts are concentrated.

d) The pressure test procedure shall be as indicated by the manufacturer of the equipment or, failing that, provide a detailed description of the pressure test procedure as well as:

-Test Conditions.

-Equipment required for test execution.

-Measure and control devices, duly checked and with adequate sensitivity. It shall be ensured that the reading is at the central third of the scale of the apparatus.

The manometers will be installed outside the vertical projection and will be preferred to position them laterally or in a higher position. During the filling of water, the circuit will be carefully vented to prevent air or steam chambers from remaining.

Due to the high energy stored in the hydrostatic test, special precautions shall be taken when the test pressure is greater than 80 bars or if the product of the test pressure (Pp) in bars by volume (V), in cubic meters is greater than 10,000, for which it is necessary to make a detailed plan of sequence of the same, time of duration and minimum distance of safety.

In the event that the minimum safety distance indicated in the plan cannot be maintained, the plan must be replaced by another additional safety standard, which must be submitted for approval by the competent authority of the Community. autonomic.

5.2 pneumatic testing.

This test is a higher risk than the hydrostatic test, so an inspection of the device must be done beforehand.

A detailed plan of the stages of its development should always be made, with pressure maintenance times during each stage, also defining the minimum safety distance.

During the test development, the zone will be marked by which no other personnel will be allowed to circulate.

6. User inspections.

(a) The user shall have the appropriate personnel, means and organization of his or her own or contracted to carry out the necessary inspections and controls during the life of the equipment or systems, to know at all times the degree of compliance with this ITC.

(b) Regardless of periodic inspections and tests, the user's inspectors shall examine and verify during the general and partial stops of the plants, those equipment which are opened for cleaning or repair. The results of such checks shall be shown in the User Registry referred to in Article 9.7 of the Pressure Equipment Regulation.

c) The inspection department of the user will carry the history of the equipment or systems. The user will check that the design conditions, failure duration, repairs, and modifications are not exceeded.

7. Inspection of the safety valves.

Safety valves shall be dismantled when the scheduled inspection stop of the system to which they belong is carried out, or when the frequency of inspections corresponds to the performance of the level B inspections for their adjustment, test and seal. The regulation shall be carried out by the test bench, taking into account the recommendations of the manufacturers.

In the case of flame boilers, the frequency of the checks shall be at least every two years.

The valves of the steam production systems, and all of them which, by their operating characteristics, allow them, may be checked at their place of placement.

The tarado and sealed checks will be monitored by a control body.
