API 5L Steel Pipe Specification (Latest 45th Edition Update)

API 5L is the implementation standard of steel pipe zpi pipeline transportation system and specification for line pipe. Random length shall be delivered as below table In addition, changes were made to Section Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

Register now while it’s still free! Download Now White Paper: The pipe is rejected L Street, NW? Non-destructive inspection and testing.

Following additional information also could be included in the PO in different situations. Meanwhile, other fluids like steam, water, slurry also could adopt the API 5L standard for the transmission purposes.

Octal is located in China recognized as a leading supplier, distributor, and manufacturer union in providing piping solutions for oil and gas company. PSL is the abbreviation of product specification level. Different manufacturing type API 5L specification covers the manufacturing types in welded and seamless. The heat identity until all related chemical tests are performed and complied the required specifications.


By hot rolled manufacturing process we could get seamless pipe diameters at most 20 inch mm. Request a Quote Now. The mainly difference between 45th Edition with previously is to add 2 additional appendix: Other than above three common tests there are other tests that required in each circumstances.

For all bend test, the weld extends to a distance of 6.

First, a revised ISO was balloted and published. A summary of some of the key requirements are: For the other content has a little difference in related standards, manufacturing technology, performances norm, inspection methods, besides adjustment of text expression.

Very prescriptive including sdition pipe attributes that must be marked on the pipe — i.

Minimum strength requirement on weld seams? Tempered and quenched Letter M: API has provided a summary of the 45th edition improvements, as per the following excerpt from them: Individual spi applicability of confirmation. By joining you are opting in to receive e-mail.

This version was started from Aprilwith collecting and analyzing of more than suggestions, finally released at the end of Disposition of pipes containing defects Clause E. Tighter requirements on chemical alloying elements for PSL 2?

For PSL2 pipe, Besides above terms, such documents shall provide means for tracing any length of the pipe to the proper test unit, including the related chemical and mechanical test results.

Qualifications of visual inspectors are identified? More over, for the same grade 44tu 5L pipe, seamless and welded chemical elements content is different, which welded pipe is required more strictly and lower on Carbon and Sulfur.

The Eng-Tips staff will check this out and take appropriate action. Purchase order must first include general information, Clause 7. By different delivery condition, there are also As-rolled, normalizing rolled, thermomechanical rolled, normalizing formed, normalized, normalized and tempered, quenched and tempered.


Delivery Conditions for each steel grades To be continue: As rolled Letter N: Disposition of defects is addressed in section C — Defects are treated in accordance with Clause C. PSL1 is more strict than PSL2 in chemical composition, tensile properties, impact work, nondestructive testing and other indicators. Acceptance criteria are given to determine when these are considered a defect L Street, NW? For example, L X42 means the minimum yield strength is Mpa.

API 5L Pipe Complete Specification Based 45th Latest Edition

Any one already compare between API 5L 44th with 45th edition? According to the stress and deformation characteristics of the specimen during the flattening process, the flattening test shall show the resistance to longitudinal cracking and circumferential cracking of the pipe, and display its internal defects and surface defects.

But the latest version of ISO Defects and imperfections — Defect, Clause 4. Therefore, API 5L steel line pipe should have high strength, high toughness and brittle fracture, and good weld ability, and suitable for sour services and in H2S environment with anti-corrosion performances.


ISO is the basis or body of the 5L standard. Jointers need not be hydrostatically level, provided spi the portions of pipe used in making the jointers were successfully hydrostatically tested prior to the joining operation. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. At present, the development trend of line pipe engineering is large diameter, high pressure gas transportation, high cold and corrosion service environment, thick wall of submarine pipeline etc.
