Classifications
Cold drawn pipe is usually divided into common cold drawn steel pipe, low and
medium pressure boiler pipe, high pressure boiler pipe, alloy steel tube, stainless
steel tube, petroleum cracking tube, and so on. According to the raw material, cold
drawn seamless steel pipes can also be classified into carbon steel thin wall tube,
alloy thin wall tube and stainless steel thin wall pipe, etc.
