Seamless Cold Drawn Steel Pipe , Cold Drawn Steel Tube
Cold drawn steel pipe is normally divided into low and medium
pressure boiler pipe, high pressure boiler pipe, steel pipe,
stainless steel pipe, oil cracking pipe, the other steel, but also
thin-walled carbon steel, alloy steel thin-walled, thin-walled
stainless steel, special steel pipe.
Cold drawn means at room temperature, after cold drawing, cold,
cold drawn, such as the processing of cold steel or steel into
various types steel. (Including a tapered pipe, oval shaped steel
pipe, etc. are manufactured using this method)
Advantages of cold drawn steel pipe: molding speed, high output,
and does not damage the coating, can be in the form of cutting
brittle various kinds of cross section, to meet the needs of the
conditions of use. Cold drawn can make the steel produces very
large plastic deformation, thus improve the yield point of steel.
