Introduction
This standard is identical to the international standard ISO 3183: 2012, which was developed to harmonize the requirements of the following standards:
— API Spec 5L: 2007;
— ISO 3183: 2007.
In preparation for ISO 3183: 2012, the technical committee of ISO TC 67 adopted the principle of dividing the basic technical requirements for pipelines for pipelines in two levels: PSL-1 and PSL-2. PSL-1 sets the basic level of pipe quality for pipelines. PSL-2 sets a higher level of quality due to additional requirements for chemical composition, toughness, strength properties and non-destructive testing. Requirements that are applicable only for the PSL-1 level or only for the PSL-2 level have a corresponding designation in the text. Requirements that do not have a specific level designation are applicable to both the PSL-1 level and the PSL-2 level.
For special applications in the oil and gas industry, ISO 3183: 2007, the following additional requirements were provided:
— PSL-2 level pipes can be ordered with manufacturing according to the certified production technology (Appendix B), the requirements for which have been extended by including detailed information on the control of critical processes in the production of rolled or sheet products, the manufacture of pipes, testing and control of products;
— PSL-2 level pipes for gas pipelines can be ordered with resistance to viscous fracture propagation (Appendix G);
— PSL-2 level pipes can be ordered with properties for use in acidic environments (Appendix H);
— pipes can be ordered as pipes for pressure pipelines (TFL) (annex I);
— PSL-2 level pipes can be ordered with properties for operation in marine environments (annex J).
Two new applications have been added to this standard:
— PSL-2 level pipes ordered for European overland gas pipelines (annex M);
— formulas for the calculation of indicators for pipes with threads and with couplings and tests for directional bending and impact bending of specimens with a V-notch (CVN) (Appendix P).
If these applications are listed in the purchase order, the application of these requirements becomes mandatory.
If pipes are ordered for two or more applications, the requirements of two or more special applications may be specified. If in such cases the technical requirements of the different applications do not match, then more stringent requirements must be applied to the intended operating conditions.
In ISO 3183: 2012, two equivalent systems for the designation of steels for pipeline pipes were adopted:
— traditional American system of designations of strength groups (designations A, B, A25 and designations beginning with the letter X);
— European system of designations for steel grades, established in EN 10027−1: 2005 (designations beginning with the letter L).
Some of the requirements and test methods used in ISO 3183: 2012 simultaneously include references to international standards and to regional or national standards of other countries, interchangeable according to their requirements.
In the text of this standard, in comparison with ISO 3183: 2012, individual phrases have been changed, some terms and symbols have been replaced by their synonyms and equivalents in order to comply with the norms of the Russian language and in accordance with the accepted national terminology and notation. Including, in accordance with the traditional national system for marking steels for pipe pipes, the term «steel grade» has been replaced by the term «pipe grade». The types of the initial billet used for making seamless pipes have been refined. In this connection, the words «ingot» and «bloom» are excluded, meaning products that are not directly the original blank for pipes. The values of units of values in the American system of units (USC) are excluded for adjustment in accordance with GOST 8.417. Some designations have been replaced in accordance with the notations adopted in the national standardization. The explanations connected with the use of the notations accepted in the American standards, contradicting to the notations accepted in the international standards, are excluded.
This standard is supplemented with a reference application YES, containing information on the compliance of state standards with reference international standards.
This standard, like the international standard ISO 3183: 2012, does not contain recommendations for the application of the above additional requirements. The need to fulfill any requirements when executing a specific purchase order is established by the customer on the basis of the intended designation of the product and the design requirements.
1 area of use
This standard specifies the requirements for seamless and welded steel pipes at two levels of product requirements (PSL-1 and PSL-2) intended for oil and gas pipelines.
This standard does not apply to cast pipes.
2 Relevance
2.1 Units of measurement
Units of the international SI system are used in this standard.
In writing the values of indicators as a decimal point, a comma is applicable, for separating the thousands digit — a space.
2.2 Rounding
Unless otherwise specified for a specific value, in accordance with ISO 80000−1 (Annex B, Regulation A), the measured or calculated values used to express the limit value must be rounded to the last significant digit to determine compliance.
NOTE — For this standard, the rounding method according to the standard [1] is considered equivalent to ISO 80000−1 (Annex B, rule A).
2.3. Compliance with this standard
To ensure compliance with the requirements of this standard, a quality management system must be applied.
Note — Certification of the quality management system is not required. To meet the requirements of this standard, it is necessary to create and adopt a quality system. The choice of the quality system, which most fully reflects the needs of the company, should be presented to the management of this company. There are many quality management systems that can be addressed both as reference manual in developing the necessary quality system, including [2] and [3], which contain provisions specific to the oil and gas industry, or [4], which contain general requirements for the system quality management that is audited. This list of standards is not exhaustive, but is for reference only.
The manufacturer must ensure that products comply with the requirements of this standard. The customer has the right to check the manufacturer’s compliance with the requirements and reject any product that does not meet these requirements.
