Cold drawing principles - The FABRICATOR

High Q values also result in low residual stress levels for cold-worked tubes. In a recent project, a Q value of 0.91 yielded a residual stress of more than 52,000 pounds per square inch (PSI) as measured by the Sachs and Espy procedure described in ASTM E1928. A draw with a Q value of 2.2 had a residual stress level of only 5,200 PSI.Advantages of cold drawn steel pipe | ASTM A234 butt weld structure cold draw steel pipeCold drawn steel pipe is a kind of steel pipe, that is, it is a type classified according to different production processes,and is different from hot rolled (expanded) pipe. In the process of expanding the diameter of the capillary tube or the raw material tube, it is formed by cold drawing in multiple passes, usually on a single-chain or double-chain cold-drawing machine of 0.5 to 100T .
