Carbon Steel Seamless Pipes also carbon steel seamless pipes, stainless steel seamless pipes, carbon steel welded pipes, stainless steel welded pipes, is used widely in machining parts, shafts, bearings, cylinders having strength of 75000 PSI tensile. They are called carbon steel rods which is pushed on the madrel to form the shape of tube. Many different sizes are available.
