API 5L X42 12M Welded Steel Pipes LSAW For Water Low Resistance
Quick Detail:
Material:ASTM A53, ST52, API 5LX42, 52, 60
Production Technology:LSAW
Product:LSAW welded pipe
Description:
LSAW-Longitudinal Submerged Arc Welded should be for spot welding and welding by one side.It is a straight line and very beautiful and good.
LSAW pipe produce progress:
(1) The machine will make the steel material to J than C, the last is O. So the pipe is round.
(2) Cut the steel material, make it fit for the pipe.
(3) Bend the material, this step is facility for welding.
(4) All the steps finish, will put this pipe into stock.
(5) Test: ultrasonic testing.hydrostatic test.
(6) Welding: Pre-welding,inner welding, outside welding
(7) We will check the material, and confirm the material is good.
