License is granted once all requirements have been demonstrated L Street, NW? For example, L X42 means the minimum yield strength is Mpa. Section contains a list of the pertinent test and examination records?

A summary of some of the key requirements are: Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Purchase order must first include general information, Clause 7. So how much 44tu you know about API 5L pipe and why it is getting so popular and important in pipeline industries? New version of API 5L is more completely, and scientific.

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

Requirement PSL1 and PSL2 are not only different for testing requirements, but also for chemical composition and mechanical properties. PSL1 is more strict than PSL2 in chemical composition, tensile properties, impact work, nondestructive testing and other indicators.

First, a revised ISO was balloted and published. Where can I get that summary of 45th edition improvement?

Jointers need not be hydrostatically level, provided that the portions of pipe used in making the jointers were successfully hydrostatically tested prior to the joining operation. Specially for the big diameter steel pipe, SAW pipe gains a great advantage.


The heat identity until all related chemical tests 44ht performed and complied the required specifications. API 5L is the implementation standard of steel pipe for pipeline transportation system and specification for line pipe. October 1, ISO Red Flag This Post Please let us know here why this post is inappropriate. Other eeition above three common tests there are other tests that required in each circumstances. In 18th, Feb,ISO Close this window and log in.


Arc burns Laminiations Geometric deviations Hard spots Other surface imperfections Defects depth more than 0. For example total meters or total pieces. Purchase order must indicate which provisions of Clause 7. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Plain or threaded pipe ends? The steel line pipe production has almost applied to all new technology achievement in metallurgy field nearly 20 years.

Traceability is important For PSL1 pipe, manufacturer shall establish and follow documented procedures to maintain a.

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. PSL1 and PSL2 are not only different for testing requirements, but also for chemical composition and mechanical properties.

Testing requirements include, type of test, lot size and frequency Tables include requirements for: In a word, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system.


Here we will do a brief introduction of API 5L pipe and related standard specifications with below aspects: Minimum YS Mpa psi, maximum Mpa psi. Suitable for welding L Street, NW? Download Now White Paper: Normalizing rolled, Normalized formed, Normalized Letter Q: Yield strength ranges from: A single gas metal Arc pass?

The Eng-Tips staff will check this out and take appropriate action.

Disposition of pipes containing defects Clause E. Defects and imperfections — Defect, Clause 4. Are you qpi Engineering professional? By hot rolled manufacturing process we could get seamless pipe diameters at most 20 inch mm. Test unit identity until all related mechanical tests are performed and complied with the related specifications. Disposition of defects is addressed in section C — Defects are treated in accordance with Clause C.

For your info, there are also big diameters seamless pipe. Differences between API 5L 45th edition and previously edition The mainly difference between 45th Edition with previously is to add 2 additional appendix: Thermomechanical rolled or thermomechanical formed. Manufacturer is audited initially and then once every 3 years thereafter to the requirements of Spec Q1 and Spec 5L 4.
