Non-destructive inspection and testing. PSL is the abbreviation of product specification level.
PSL1 is more strict than PSL2 in chemical composition, tensile properties, impact work, nondestructive testing and other indicators.
What information that will be required for purchasing API 5L pipe a. Random length shall be delivered as below table Zpi how much do you know about API 5L pipe and why it is getting so popular and important in pipeline industries?
API Specification 5L, 46th Edition
PSL1 and PSL2 are not only different for testing requirements, but also for chemical composition and mechanical properties. For example, L X42 means the minimum yield strength is Mpa. Normalizing rolled, Normalized formed, Normalized Letter Q: OD Outside diameter and WT pipe wall thickness g: Delivery Conditions for each steel grades To be continue: API 5L pipe length tolerances shall be complied as following conditions: The steel line pipe production has almost applied to all new technology achievement in metallurgy field nearly 20 years.
This standard is not applicable to cast pipe. Request a Quote Now. API 5L pipe sizes and tolerances Tolerances for diameter and out of roundness Tolerances for wall thickness Tolerances for pipe lengths API 5L pipe length tolerances shall be complied as following conditions: For intermediate grades, API 5L pipe grade shall be in one of following description format: While we can provide answers zpi many of these questions, there are certain categories of queries to which API cannot provide assistance.

API 5L Pipe Complete Specification Based 45th Latest Edition
As the steel line pipe grades higher, more strictly control on the carbon equivalent control, and higher mechanical strength performances. By different delivery condition, there are also As-rolled, normalizing rolled, thermomechanical rolled, normalizing formed, normalized, normalized and tempered, quenched and tempered. Statistics Events Certifications Directories.
Also, effective November 1 st, API 5L audits will be conducted to the 46 th edition of the document.
API 5L Steel Pipe Specification (Latest 45th Edition Update)
Individual annexes applicability of confirmation. By hot rolled manufacturing process we could get seamless pipe diameters at most 20 inch mm.
Skip to main content. The letter L followed by the specified minimum yield strength in Mpa.
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. Differences between API 5L 45th edition and previously edition The mainly difference between 45th Edition with previously is to add 2 additional appendix: In a word, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system.
The companion video, highlighting key changes and the implications for API Monogram licensees, is now available. The mainly difference between 45th Edition with previously is to add 2 additional appendix: But the latest version of ISO Modern API 5l steel line pipe belongs to low carbon or ultra-low carbon micro alloy steel.
With a subscription on Compass, you are ensured consistent and up-to-date access to the latest API standards. Individual annexes applicability of confirmation Additional information Following additional information also could be included in the PO in different situations.
