Scope
ANSI / API 5L specifies the manufacture of two product levels (PSL1 and PSL2) of seamless and welded steel pipe for the use of a pipeline in the transportation of petroleum and natural gas. For material use in a sour service application, refer to Annex H; for offshore service application, refer to Annex J of API 5L 45th Edition.
API 5L pipes may be classified according to the following criteria:
The main advantages of API 5L pipe are:
Size Range
API 5L pipes are available in dimensions between from 2 to 28″ (seamless execution) and up to 80″ in welded execution (generally, LSAW i.e. longitudinal submerged arc welding).
The API 5L and ASME B36.10 pipe dimensions and weights are, in fact, identical.

Process
Ingots, blooms, billets, coils or plates used for the manufacture of pipe shall be made via basic oxygen, electric furnace 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. Coil or plate used for PSL2 pipe shall not contain any repair welds.
Application:Tube for conveying gas, water, and oil in both and natural gas industries etc.
Casing:Casing is a large diameter pipe that serves as the structural retainer for the walls of oil and gas
wells, or well bore.It is inserted into a well bore and cemented in place to protect both subsurface
formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take
place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi.
Tubing: Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to
the surface after drilling is complete. It is made to withstand the pressure generated from the extraction
process. Tubing is manufactured in the same way as casing, except that an additional process known as
"upsetting" is applied to thicken the pipes.
