For the other content has a little difference in related standards, manufacturing technology, performances norm, inspection methods, besides adjustment of text expression. It is to use radiographic, ultrasonic or other methods not to breaking the material in API 5L standard, to reveal pipe defects, imperfections.

Differences between API 5L 45th edition and previously edtiion The mainly difference between 45th Edition with previously is to add 2 additional appendix: For all bend test, the weld extends to a distance of 6. Request a Quote Now.
API | API Specification 5L, 46th Edition
Statistics Events Certifications Directories. For example total meters or total pieces. As the development of pipeline steel plate making technology, pipe forming and welding technology also has been much improved, so a lot of ERW pipe and SAW pipe used in the pipeline constructions.
API 5L is the implementation standard of steel pipe for pipeline transportation system and specification for line pipe. With a subscription on Compass, you are ensured consistent and up-to-date access to the latest API standards.
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. Bend test Cracks should not occur in any part of the sample and opening of weld shall not occur as well. 5k
API Specification 5L, 46th Edition
The heat identity until all related chemical tests are performed and complied the required specifications. Specially lahest the big diameter steel pipe, SAW pipe gains a great advantage. But the latest version of ISO In 18th, Feb,ISO The steel line pipe production has almost applied to all new technology achievement in metallurgy field nearly 20 years.
PSL is the abbreviation of product specification level. On the other hand, seamless manufacturing type usually for the small diameters pipe, the pipe diameter is less than mm or 6 inch, the seamless steel pipe is more applied than steel pipe in welded. Other than above three common tests there are other tests that required in each circumstances.
What information that will be required for purchasing API 5L pipe a. Reference documents to API 5L. API 5L pipe length tolerances shall be complied as following conditions: Key Changes Updated and expanded requirements for mill jointers differentiate between double-jointers and mill jointers; avoid welding consumables environmental contamination; require qualification standards; new process testing requirements; clarify offset and undercut requirements; standardize marking requirements; reference weld repair annex ; Updated requirements for pipe end squareness; Updated requirements for hardness testing on PSL 2 pipe for sour service and PSL 2 pipe for offshore service; New annex for strain-based design requirements PSL 2 pipe for applications requiring longitudinal plastic strain capacity Effective Date and Program Implications The Monogram Program effective date will be November 1, For your info, there are also big diameters seamless pipe.
By hot rolled manufacturing process we could get seamless pipe diameters at most 20 inch mm. The mainly difference between 45th Edition with previously is to add 2 additional appendix: Normalizing rolled, Normalized formed, Normalized Letter Q: This version was started from Aprilwith collecting and analyzing of more than suggestions, finally released at the end of Octal is located in China recognized as a leading supplier, distributor, and manufacturer union in providing piping solutions for oil and gas company.
For intermediate grades, API 5L pipe grade shall be in one of following description format: PSL1 and PSL2 are not only different for testing requirements, but also for chemical composition and mechanical properties.
By different delivery condition, there are also As-rolled, normalizing rolled, thermomechanical rolled, normalizing formed, normalized, normalized and tempered, quenched and tempered. For additional information please lstest the e-mail compass api.
Traceability is important For PSL1 pipe, manufacturer shall establish and layest documented procedures to maintain a. PSL1 is more strict than PSL2 in chemical composition, tensile properties, impact work, nondestructive testing and other indicators.
