Specification for seamless steel pipe

Seamless pipe is extruded and has no seems and is generally stronger.
Seamless steel pipe is also called CDS pipes (Cold drawn seamless pipe). It’s is used widely in marching parts, shafts, bearings, cylinders having strength of 75000 PSD tensile.

It is a solid carbon steel rod which is pushed on to the mandrel to form the shape of tube. It is available in different sizes.
