JIS standard seamless steel pipes

Japanese Commercial Standards (JIS) developed by the company apply to a wide array of commercial services and technologies such as autos, metallurgy, ships and medical equipment. Seamless steel pipe is likewise called CDS pipes (Cold drawn seamless pipe). It’s is used widely in matching parts, shafts, bearings, cylinders having strength of 75000 PSD tensile. It is a solid carbon steel rod which is pressed on to the mandrel to form the shape of tube. It is offered in different sizes. The technique for making cold-drawn smooth pipes involves taking a round “billet” or bar of steel and boring it in […]
