What is a API 5L Line Pipe Standard Scope?
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.
API 5L Line Pipe Standard 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.
In a word, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system. Meanwhile other fluids like steam, water, slurry also could adopt the API 5L standard for the transmission purposes.
Different Manufacturing Types
API 5L specification covers the manufacturing types in welded and seamless.
Welded Type: ERW, SAW, DSAW, LSAW, SSAW, HSAW Pipe
For API 5L welded pipe common types as Follows:
ERW: Electric Resistance Welded, for pipe diameter normally under 24 inch.
DSAW/SAW: Double Submerged Arc Welding / Submerged Arc Welding, a substitute welding method than ERW for larger diameter pipes.
LSAW: Longitudinal SAW, for diameter up to 48 inch. Also called JCOE manufacturing process.
SSAW/HSAW: Spiral Subemerged Arc Welded / Helical SAW, pipe diameters up to 100 inch.
Seamless Type: Hot Rolled Seamess and Cold Rolled Seamless Pipe
Seamless manufacturing type usually for the small diameters pipe, normally diameter under 24 inch.
(For the pipe diameter is less than 150 mm or 6 inch, the seamless steel pipe is more applied than steel pipe in welded.)
There are also big diameters seamless pipe. By hot rolled manufacturing process we could get seamless pipe diameters at most 20 inch (508 mm). But if you need the seamless pipe more than 20”, we can get it through hot expanding processes, maximum diameters to 40 inch 1016 mm.
