Description
Japanese Industrial Standards (JIS) and British Standard(BS)seamless pipes developed by the organization apply to a wide variety of industrial services and technologies such as automobiles, metallurgy, ships and medical equipment.
Seamless steel pipe is also called CDS pipes (Cold drawn seamless pipe). It& acute;s is used widely in machining 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. The method for making cold-drawn seamless pipes involves taking a round “billet” or bar of steel and boring it in the center, turning it, cutting it, heating it to make it more pliable, then & quot;drawing& quot; it (extruding or pulling it) to make it a longer and thinner tube.
JIS and BS seamless pipe according to alloy, stainless steel or carbon. It tests steel& acute;s properties, hardness, resistance to corrosion, pitting, heat treating processes and others.
