    Stainless steel seamless pipe, also known as stainless steel seamless tube, is a long hollow cylinder used for moving fluids (liquids or gases).

    “Stainless seamless pipe” and “stainless steel tube” are almost interchangeable, although minor distinctions exist-generally, a tube has tighter engineering requirements than a pipe.

    XINHANG STEEL is a professional manufacturer specialized in manufacturing seamless pipes in large, medium, and small diameters.

    Various stainless steel seamless pipe are produced with complete specifications and supreme quality.

    Stainless steel seamless pipe are widely used in such industries as petroleum, chemical industry, machinery, electric power, chemical fiber, papermaking, printing and dyeing, food and pneumatic parts etc.

    The company is provided with complete inspection equipment and adopts technical standards for products such as: seamless pipe for fluid transportation, seamless pipe for construction, seamless for boiler and heat exchanger.

    The outside diameter of seamless stainless we produce ranges from 6mm to 406.4mm. The wall thickness is 1mm to 50mm.Our factory and products are certified by ISO 9001,PED,TUV,LR,KR,ABS,BV AND DNV/GL.
