Onshore Offshore Oil Gas Pipelines Od508mm Lsaw Pipe
Straight Seam Submerged Arc Welded Steel Pipe LSAW Steel Pipe
LSAW steel pipes or Longitudinally Submerged Arc Welded steel pipes are primarily used in onshore and offshore oil and gas pipelines where high performance and tight tolerances of piping materials are critical. Steel Pipe Sourcing is one of the most-appreciated LSAW steel pipe manufacturers in China that offers premium quality LSAW steel pipes for such applications.
JCOE LSAW pipe forming process:
Forming: After several steps of stamping on the JCO forming machine, first half of the steel plate is pressed into a "J" shape, then the other half of the steel plate is pressed into a "J" to form a "C" shape, and finally pressurized from the middle to form An open "O"-shaped tube blank is formed.
