TISCO 30 Inch 2B Seamless Structural Steel Pipe Seamless Carbon
Steel Pipe
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.
The easiest way to identify the two is to look at the look. There are seam steel pipes, there will be a welded straight line,
or the surface is polished. There is also straightness, uneven
thickness, and it can't be tested.
