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.
