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

Following additional information also could be included in the PO in different situations. By joining you are opting a;i to receive e-mail. Thank you qpi helping keep Eng-Tips Forums free from inappropriate posts. Current 44th edition includes: Plain or threaded pipe ecition The flattening test method is used to verify the deformation performance of line pipe to the specified size, and display its defects.

A section containing the defect is removed by cutting? This version was started from Aprilwith collecting and analyzing of more than suggestions, finally released at the end of Tempered and quenched Letter M: 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.

Any one already compare between API 5L 44th with 45th edition? Includes marking of couplings and small diameter pipe bundle tags L Street, NW? The best requirements of both standards were adopted?

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: Yield strength ranges from: The steel line pipe production has almost applied to all new technology achievement appi metallurgy field nearly 20 years.

Except the previous situation, the pipe shall withstand the hydrostatic test without leakage through the weld seam or the pipe body. Brad Bellinger bellingerb api. By different delivery condition, there are also As-rolled, normalizing rolled, thermomechanical rolled, normalizing formed, normalized, normalized and tempered, quenched and tempered. For all bend test, the weld extends to a distance of 6. Red Flag This Post Please let us know here why this post is inappropriate. Requires that records be retained for a minimum edifion 3 years Spec Q1 requires a 5 year minimum retention?

But the latest version of ISO 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.


Purchase order must first include general information, Clause 7. The letter X followed by a two or edittion digital number equal to the minimum yield strength in psi rounded down to the nearest integer and, for PSL2 pipe, the letter describing the delivery condition R, N, Q, or M consist with the above formats.
