Wholesale Seamless Steel Pipe
Seamless Steel Pipe-EC1

A seamless steel pipe is a circular pipe having a hollow section and no seams around it.  The seamless steel pipe is made of carbon steel, alloy steel, stainless steel ingot or solid tube blank, and then is made by hot rolling, cold rolling or cold drawing.  Seamless pipes are considered superior to welded pipes as they are built using monolithic steel billets, with intrinsic mechanical strength, without seam welds.

Cold Drawn Seamless Fluid Steel Tubes
Fluid pipe

Fluid pipe, originally named waterproof pipe, is a type of pipes that move liquids around in a similar manner as transport pipes. These pipes are created by combining transport pipes with pipe sealant. Fluid pipes can be used to transport oil, fuel, water and lava to different locations. These pipes allow liquids to be transported into engines, tanks and oil refineries. When a pipe is not connected to anything, it will fill itself up instead of pouring the contents on the floor. 

ASTM A213 Seamless Structural Steel Pipe
