API Welded Steel pipes are produced by two types such as longitudinal-submerged arc-welded is called LSAW and spiral-submerged arc-welded is called SSAW. API 5L LSAW Pipe is produced by bending and welding of steel plates and LSAW pipe. API 5L SSAW pipes are produced by spiral welding of steel Plate coil.
API 5L Spec line pipe according to the provisions of the production process were divided into 8 kinds of seamless steel pipe, ERW steel pipe, submerged arc welded pipe and so on. But the most commonly used types are seamless steel pipe (Seamless), straight seam high frequency electric resistance welded pipe (Electric Resistance Welding, named as ERW), LSAW pipe (Longitudinally Submerged Arc , ss400 steel for building decoration thickness
Both LSAW pipe and SSAW pipe are SAW pipe (Submerged Arc Welding Steel Pipe), is manufactured by making use of a submerged arc soldering process for preparing the steel and it results in high density pipe. Owing to the flux layer, there is no instant heat loss and it gets concentrated near the weld. , ss400 steel for building decoration thickness Applications of the API 5L welded line , ss400 steel for building decoration thickness
SSAW steel pipe,Spiral submerged arc welding steel pipe SSAW steel pipe API5L API 5L, EN-10208, GB9711.1/2, ISO A, B, X42, X46, X52, X56, X60, X65, X70 SSAW steel pipe API5L 1.Uses:Used for the conveyance of water, gas, or pertroleum products and piling pipe
SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L standard. These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction.
The SSAW steel pipe is made utilizing hot rolled steel strip which is spiraled at room temperature level to be bonded. Automatic immersed arc welding is the most commonly utilized technique in the spiral tube production, and the end items come with welding joint both inside and outside.
