Samples for testing in the transverse direction should be taken in cases when the shape and thickness of the product.

Steel should be set below the specified minimum allowable elongation after fracture of the sample in a specified gauge length :

(the area of the original cross-section of the specimen gauge length):

— 14% or more in the transverse direction or, in rare cases, in the longitudinal direction when it is critical

— 16% or more in the longitudinal direction or in the transverse direction, if it is critical.

However, you can be set to smaller values allowable elongation (in comparison with specified in 4.2), for example, for mounting or casting, but subject to proposals by the relevant agreed and approved measures to compensate the impact of lower tolerances.

Note — Examples of such compensation:

— apply at design stage of high safety factors;

— the application of the corresponding burst tests to demonstrate the plastic properties of the material.


If the gauge length is different from , the lowest valid value of the elongation after fracture should be determined by resampling these values are 14% and 16% special table:

— GOST R ISO 2566−1 for carbon and low alloy steels;

— or the smallest allowed value of the strength at 1% elongation disproportionate, as defined in 4.2.5.2, and enumeration).

While it is preferable to use the following series of temperatures:

100 °C, 150 °C, 200 °C etc up to the highest operating temperature specified in the design.

The smallest permissible value of the strength specified for operation at room temperature, can be used for temperature 50 °C and below.

Strength values for temperatures in the range from 50 °C to 100 °C is determined by interpolation between the values given for 50 °C and 100 °C.

Set the lowest allowable strength values at elevated temperature must be determined by [36].

4.2.5.6 Long-term strength

For materials intended for use in the temperature range of the creep, take the average value of the long-term strength for materials manufactured according to national standards, similar to [37], and for European materials — at [37], subject to the requirements of Annex B.

In cases where the value of the long-term strength can only be obtained over a long period of time, or by extrapolating or computing insufficient number of test results (see [37]), should be as precautions to increase the safety factor or to reduce the interval of regular inspections.

The supplier of the material should give the boilers the manufacturer a written statement that the delivered product meets the specified requirements and that the applied technological processes are equivalent in their impact on the material conditions of obtaining test results.

4.2.5.7 Technological properties

If necessary, establish requirements to deformation (for example, on the basis of tests for the flattening or the distribution or of tests on determination of deformations in the thickness direction of hire, see [38]), or set requirements for other technological properties relevant to the processing and exploitation of the material.

Technological properties of Russian materials must meet the regulatory requirements for supply of material.

4.2.5.8 other properties

If necessary, establish requirements on the availability of properties is not envisaged 4.2.5.2−4.2.5.7 (e.g. corrosion resistance) and determine the appropriate control procedure.

4.2.5.9 surface Condition and the absence of internal defects

The material should be excluded external and internal defects which may impair its performance.

Requirements for non-destructive testing should be as for similar products of similar material listed in Appendix A and 4.1.6.

4.2.5.10 Dimensions, tolerances on dimensions, shape and weight

Should be, determined by reference to the appropriate standard sizes.

4.2.5.11 Testing and inspection

To assess compliance of the supplied material to the requirements technical delivery conditions must determine the following:

a) types of documentation inspection (see section 6);

b) properties to be checked and confirmed (e.g., by analyzing castings or tension test);

c) conditions of carrying out of special inspection and testing (e.g. acceptance testing), namely:

1) composition and maximum size of the test block (for example, the greatest mass or the quantity of a product of a casting or belonging to the same batch heat treatment), and the number of product samples required for a single test, and the number of test samples taken from one sample product;

2) the location and orientation of samples for testing on a sample of the product;

3) if necessary additional conditions for the selection and preparation of specimens and samples;

4) the requirements of European or national standard describing test methods;

5) preparatory (rehearsal) tests [34].

4.2.5.12 Marking

Forms for individual products define the technical terms of delivery, the appropriate conditions of labeling 4.1.8.

4.2.5.13 Additional requirements

Manufacturer of boilers appoints additional tests deemed appropriate for this case.

Note — as appropriate, the lists L1 and EMDS must include some basic instructions for processing and/or restrictions on its use (see table 3.1).

4.3 Material requiring special assessment properties

Special assessment properties, you need to spend for the materials, which are used in special cases not provided for in 3.3.3 and 3.3.5 and is not intended for frequent use. Such materials should be defined in the specifications and approved by the responsible authority for 3.3.6.

In appropriate cases, the assessment Protocol includes instructions for the processing of the material. In the specification (in the section „General information“) shall be determined by individual conditions of use of the material.

5 Materials for parts operating without impact pressure

Materials for the manufacture of supports, fences, pallets, etc. of the parts welded to the boiler, but not exposed to the pressure supply according to the specification that reflects at least the requirements for the chemical composition and ability to withstand loads in tension. You must define (set) the ability to withstand shock loads, if necessary by operating conditions. Materials must also be compatible with the material of the part to which you are fastening.

6 Documentation of the inspection control

The results of the inspection and tests necessary to issue a certificate in accordance with [2]:

- to attach materials in the form of a test report (according to 2.2), at [39];

— for basic materials and certified systems, in the form of certificate of type 3.1.In [39], unless the buyer requires an inspection certificate of type 3.1.And, 3.1.Or an inspection report type 3.2, i.e. conducting direct inspections [2]. The certificates must contain information that the equipment manufacturer approves products in accordance with this standard, and shall specify the name of the responsible person. When testing new materials document the results of the inspection are in accordance with the requirements of the list L1 (EMDS); and verification of consumables for welding report in form 2.2.

Annex b (mandatory). Determination of tensile breaking method of creep for new materials

The App
(required)

Should be carried out in two stages, according to table B. 1.


Table B. 1 — Definition of the desired strength at fracture of the material from the creep

Test conditions	The evaluation procedure	Further testing
First stage: Obtaining preliminary data to list L1 (ЕМDS)
Tests for creep of each of the three samples taken from one swimming trunks, three trunks, at least at two different temperatures (the temperature difference is 50 °C to 100°C), conducted over 10,000 hours (up to destruction). In cases where embrittlement takes place for each heat and for each test temperature carry out the test of one sample filed for more than 10,000 hours (up to destruction).	For the range of scattering of not more than 10%, the coefficient of extrapolation is less than three to one. Maximum application temperature is less than (or equal to) the maximum test temperature. When the range of scattering more than 10% extrapolated values are not included in the list of data; computations should be performed in each case.	Each manufacturer: carry out tests on creep (at least five samples) of not less than one melting at not less than two temperatures for more than 30,000 hours (until the destruction). If necessary, at each temperature feel at least two skewed samples for over 30,000 hours (up to destruction).
Second step: Receive final data for lists L1 (EMDS)
Tests for creep of each of the five samples (minimum) taken from one of the melting heats for six (no less) at temperatures that differ from one another not more than 50 °C, carried out during the period, amounting to 35% of the maximum design operating time.	When the range of scattering not more than 20% coefficient of extrapolation is less than three to one. Maximum application temperature exceeds no more than 25 °C maximum temperature of the tests.	New manufacturers test the samples not less than one test temperature for more than 30,000 hours (until the destruction). In the case of extending the period of application of these conduct tests on creep (at least five samples) for a single casting with two (at least) the test temperatures for over 30,000 hours (up to destruction).

Application (required). Boilers energy-technology units with chemically aggressive media

C. 1 General

This Appendix describes the special requirements of special materials for the manufacture of parts operating under pressure in the boilers, exposed to chemically aggressive environments. These special requirements are additional to the other requirements of this standard that remain in force.

C. 2 Special requirements for composite tubes

P.2.1 Composite pipe

Composite pipe consists of an inner ferrite tube, perceiving pressure, and resistant to corrosion of the outer shell, connected by a metallurgical method.

P.2.2 General information

Materials made in accordance with the present application, must meet all the requirements of documents (latest edition) listed in 3.3, here only if not done otherwise.

The composite pipe is seamless pipe, produced by the process of hot extrusion, or by hot extrusion followed by cold working. The workpiece of the two components obtained by co-extrusion at high temperature, to ensure robust metallurgical connection.

Put all the pipes after heat treatment performed at a temperature suitable for obtaining optimum mechanical connection of the two components and provide corrosion resistance.

The pipe should be straight (see p.2.5.2} and have no damage and defects.

P.2.3 Chemical composition

Must meet the requirements of 3.3 of this standard.

P.2.4 Mechanical and technological properties

P.2.4.1 Test internal ferrite tubes tensile

Tests should be carried out in a number of tubes of arbitrary length, at p.2.4.2. Mechanical properties shall conform to the characteristics listed in the specifications drawn up by 3.3.

P.2.4.2 expansion Testing

Take one test specimen from each end of each tube (of arbitrary length). The ring must be subjected to the distribution of not less than 30% of the inner diameter or to failure (if it occurs earlier). The sample should not contain defects (based on results of visual inspection). The test of Russian materials should be carried out to GOST 8694, European materials at [42].

P.2.5 Tolerances

P.2.5.1 Allowable variation of outer diameter and wall thickness

The outer diameter D±0,5% but not more than:

— 0.30 mm — for pipes with a diameter less than 50.8 mm;

— 0,80 mm — for pipes with diameter from 50.8 mm to 325 mm;

— 1.0 mm — for pipes with a diameter of 325 mm.

Full wall thickness:

— if D is less than 50.8 mm: 12,5% -0%;

— if D isequal to or more than 50.8 mm: 15% -0%.

The thickness of the component stainless steel: 0.40 mm check eddy current along the length of each pipe.

P.2.5.2 Allowable deviation from straightness

— no more than 1.5 mm per 1000 mm for pipes with wall thickness up to 30 mm;

— not more than 3,0 mm 1000 mm for pipes with wall thickness over 30 mm.

Curvature throughout the length of the pipe should not exceed 15 mm.

P.2.6 finishing the surface

Pipe must be pretreated with from scale.

P.2.7 Ultrasonic test

P.2.7.1 Ultrasonic testing metallurgical connection of composite pipes

P.2.7.1.1 the Volume of testing

The test procedure should ensure a full testing of the total.

P.2.7.1.2 Standard sample

Needs to be manufactured from pipe of the same nominal length, dimensions, surface finish and heat treatment as the subjects of the pipe.

From the inner surface of the tube bore radius, hole diameter of 5 mm with a flat bottom, which coincides with the boundary of the two materials. Ultrasonic device, with the selected width of the probing beam and the selected step and scan speed, must take at least one signal, reflected from flat bottom holes, and this signal is received as a reference. The instrument should be adjusted at the production and reception clearly recognizable reference signal. The amplitude of the reference signal is used for regulating the visual signal on the cathode screen or the threshold value of the electronic counter.

P.2.7.1.3rd Criterion of suitability

I believe that the pipe has successfully passed the test if no signal has been received, a superior signal of the standard. Pipe with defects (having the signals from the defects that exceed the signal from the Etalon) is rejected. If defective pipes cut off the defective part, then the remaining part (or parts) is considered passed the test.

P.2.7.2 Ultrasonic testing of composite pipes in presence of longitudinal and transverse defects

P.2.7.2.1 test Method

The test is performed by immersion. Scanning is necessary to carry out the refracted waves (refraction of the ultrasonic beam is approximately 45°). At longitudinal scanning beams directed in two opposite directions chordates, while transverse scanning in two opposite axial directions.

P.2.7.2.2 Standard sample

Made from a section of a pipe of the same nominal dimensions, material, surface roughness and nominal heat treatment, and the subjects of the pipe.

On the outer and inner surfaces is applied to the lathe cuts the same direction, size and cross section table C. 1. The dimensions and cross section of the notches must be checked by the manufacture of the cast with the use of plastic substances.


Table C. 1 — Parameters of cuts

The type of incision	Location	Nominal depth, mm	Length, mm	Profile
Longitudinal	Inside	5% of the full nominal wall thickness, but not less than 0.20 mm. Tolerance: 10%	25	The groove width of 1.5 mm
Longitudinal	Outside	The groove width of 1.5 mm
Cross	Inside	The groove width of 1.5 mm
Cross	Outside	The groove width of 1.5 mm

P.2.7.2.3 Calibration

To complete the calibration standard sample is carried out using the scanning head with the same speed and in the same direction as the test pipe.

P.2.8 thickness Control component stainless steel

P.2.8.1 General information

Measurements should be performed using eddy current testing device designed to determine the thickness of non-metallic or non-magnetic layers of the ferromagnetic material.

P.2.8.2 Calibration

To perform calibration, it is necessary to use a two segment composite pipe: single — component, from stainless steel with a thickness closest to the minimum allowable thickness; and the other with a component of stainless steel with a thickness, as near as possible to the maximum allowable thickness.

P.2.8.3 Criteria of suitability

I think that the pipe passed the test if no signal has been received beyond the tolerances prescribed for the austenitic layer.

Pipe austenitic layer beyond the limits of marriage. Defective parts defective pipes cut off and the remaining part considered to have passed the test.

P.2.9 Guidance for conducting inspections and tests

Inspection and testing should be carried out to table C. 2. Ultrasonic test is performed instead of hydrostatic tests (see table C. 2).
