Seamless steel pipe is also called CDS pipes (Cold Drawn Seamless Pipe). It’s is used widely in machine 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.
Usage: In industrial plants, high pressure gases and liquids are used for the transfer of fluids chapter.
