This standard specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
This standard is applicable to the manufacturing, inspection, marking, coating, recording and loading of seamless pipe and welded pipe for pipeline transportation systems of petroleum and natural gas industries.
This standard is not applicable to cast pipe.
2 Conformance
2.1 Manufacturing
In this standard, data are expressed in both International System (SI) units and United States Customary (USC) units. For a specific order item, only one system of units shall be used, without combining data expressed in the other system. Data values expressed in SI and USC units shall not be combined on the same inspection document or in the same required pipe marking sequence.
Where product is tested and verified against requirements using one measurement system (USC or SI), and an inspection document is issued, with data reported in the alternate measurement system units, a statement shall appear on the inspection document indicating that the data presented was converted from the measurement system used for the original inspection.
The purchaser shall specify whether data, drawings, and maintenance dimensions of pipes shall be in the International System (SI) or US Customary (USC) system of measurements. Use of an SI data sheet indicates that the SI measurements shall be used. Use of a USC data sheet indicates that the USC system of measurements shall be used.
2.2 Rounding
Unless otherwise stated in this standard, to determine conformance with the specified requirements, observed or calculated values shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the limiting value, in accordance with ISO 80000-1:2009, Annex B, Rule A.
Note: For the purposes of this provision, the rounding method of ASTM E29-08 [1] is equivalent to ISO 80000-1:2009, Annex B, Rule A.
2.3 Compliance to This Standard
A documented quality system shall be applied to assist compliance with the requirements of this standard.
Note: Documentation of a quality system does not require certification by a third party certification body. Only the creation or adoption of a written quality system is necessary to meet the requirement of this standard. ISO defers to the expertise of responsible quality management personnel to create or adopt the system which best reflects the need of each company. There are many existing quality management systems to which personnel can refer for guidance in the development of an appropriate quality system, including ISO/TS 29001[2] and API Q1[3], which contain provisions specific to the oil and gas industry, or ISO 9001[4], which contains general requirements for quality management systems that are auditable. This list is not exhaustive and is provided for information only.
A contract may specify that the manufacturer shall be responsible for complying with all of the applicable requirements of this standard. It shall be permissible for the purchaser to make any investigation necessary in order to be assured of compliance by the manufacturer and to reject any material that does not comply.
