Production of Cold Drawing Petroleum Cracking Tube

Production of cold drawing petroleum cracking tube can be cold-rolled, cold drawn, cold-drawn, cold-mix production. Using drawing process, a simple equipment, low investment, easy operation and maintenance and so on. But the drawback is the middle step of many, lumber rate. Using cold process equipment is more complex, and more investment, but can reduce the intermediate processes, improve the yield, high seamless steel product size, and surface accuracy, especially for high-precision seamless and extremely thin-walled seamless tube. 

Due to limitations mill roll pass by the number and cost of finished product specifications can not be too much; cold-rolled and cold drawn joint production process to produce the finished product, with good quality steel processing cycle time is short, reduce intermediate degreasing, heat treatment, faint, Jiao straight processes, saving energy, reducing metal consumption, less raw material specifications and so on. Petroleum cracking tube can be cold drawn pickling acid, hydrochloric acid, mixed acid, hydrofluoric acid and the like. Carbon steel and alloy seamless steel suitably sulfuric acid, high-quality carbon structural steel and alloy steel seamless precision appropriate to hydrochloric acid.
