LSAW ( Longitudinally Submerged Arc Welding ) Pipe can be divided into UOE and JCOE pipe according to its processing methods . LSAW steel pipe has the characteristics of relatively simple process and fast continuous production , and has widely used in oil and gas , water transmission , engineering , offshore projects .

LSAW pipe used to convey low pressure liquid or high pressure petroleum or natural gas, and can be also used widely in structural supports or foundation. The advantage for LSAW type is they could produce more thick wall thickness of pipes, maximum to 120mm.

Chemical Composition and Mechanical Properties of LSAW Steel Pipe

Process

The three main forming steps of the UOE LSAW pipe forming process include : steel plate pre-bending , U forming and O forming . Each process uses a special forming press to complete the three processes of steel plate pre-bending , U forming , and O forming in sequence , so that the steel plate is deformed into a round tube .

After several steps of stamping on the JCO forming machine , first half of the steel plate is pressed into a "J" shape , and then the other half of the steel plate is pressed into a "J" shape to form a "C" shape , and finally an open "O" is formed by pressing from the middle Type tube blank.
