After a series of cold-rolled pipe has the following characteristics:
1, Through the organization of cold rolled grain fine pipe, pipe mechanical and physical properties compared with the superior;
2, Cold rolling mill for the correction capability of the original tube wall thickness deviation is large, precise geometry, low surface roughness;
3, Pass deformation larger, up to 70% -85%;
4, Cold-rolled production pipe can significantly reduce intermediate steps, such as heat treatment, pickling, beginning, straightening and cutting, to reduce the metal materials, fuel, electricity and other auxiliary materials and human consumption;
5, The method to produce cold-rolled thin wall and ultra-thin wall, inner and outer surfaces scratch-free quality pipe;
6, Be effectively rolled high-alloy, poor ductility various metal pipe.
