Product Description

API 5L PIPE SPECIFICATIONS

Hebei Zhongji stocks API 5L pipe in grades B and X42 – X70.

API 5L Grade B Pipe Pressure Rating

Scope

ANSI / API 5L specifies the manufactureof two product levels (PSL1 and PSL2) of seamless and welded steel pipe for theuse of a pipeline in the transportation of petroleum and natural gas. Formaterial use in a sour service application, refer to Annex H; for offshoreservice application, refer to Annex J of API 5L 45th Edition.

Process

Ingots, blooms, billets, coils or platesused for the manufacture of pipe shall be made via basic oxygen, electricfurnace or open hearth in combination with a ladle refining process. For PSL2,the steel shall be killed and melted according to a fine grain practice. Coilor plate used for PSL2 pipe shall not contain any repair welds.
