seamless steel pipe

Seamless pipe

seamless pipe feature

 

     Carbon steel seamless pipes for use in low and medium pressure boilers, petroleum casing tubes, ships,
fluid conveyance, petroleum cracking, chemical fertilizer equipments, structures, and hollow pumping rods.we
 can produce seamless steel pipes from OD3/4" to Od32", thickness SCH30,SCH40, SCH80, SCH160 and
 so on, according to the standards such as GB、ASTM、API 5L、API 5CT, DIN, and JIS.
