TPCO
Welded steel pipe
 
Welded steel pipe is formed by rolling plate and welding the seam. It is cost-effective pipe with tighter Dimensional tolerances and less weight. It is intended for conveying gas, vapor, water or other liquid in low and medium pressure ambient, such as water mains system, sewerage system, Oil and gas pipeline, fire protection service, etc.
 
There are ERW and EFW production processes. And we mainly supply HFW (High frequency welding) pipe in advanced technology. The weld seam of HFW pipe is heat treated after welding that no untempered martensite remains. And the weld flash can be removed from both inner and outer surfaces.
 
Welded pipe
 
We provide welded steel pipe as standard:
 
ASTM A53 Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded
