ASTM A53 ST52 ERW Welded Steel Pipes , Hot Rolled Black Welded Steel Tubing
Quick Detail:
Product:ERW welded pipe
Material:ASTM A53, ST52,
Production Technology:ERW
Description:
ERW welded pipe production line can produce resistance high frequency straight seam welded pipe, square tube, rectangular tube and steel sheet pile, etc.
ERW pipe produce progress:
We will check the material, and confirm the material is good.
Cut the steel material, make it fit for the pipe.
Bend the material, this step is facility for welding.
The machine will make the steel material to J than C, the last is O. So the pipe is round.
Welding: radio-frequency welding.Contact welding and induction welding
Test: ultrasonic testing.hydrostatic test.
All the steps finish, will put this pipe into stock.
ERW ADVANTAGE:
High pressure,Little resistance,Under low temperature, Under corrosion,Easy installation and maintenance.
