Stainless Seamless Pipe

Stainless seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless pipes are thought to be able to withstand higher pressure, higher temperatures, higher mechanical stress and a corrosive atmosphere. It can be found in a wide range of applications such as in oil and gas, refinery, petrochemical, chemical, fertilizer, power, automotive, bearing, mechanical and structural.

Materials:  TP304, TP304L, TP321,TP316L, 316Ti, TP310S,TP317,TP904L etc.
Standard: ASTM A312, A213, A269, DIN2462, DIN10216, GOST JIS (G3463, G3459)..
