Today we come to understand what are the characteristics of the production of cold drawn steel pipes.
1. High production efficiency: It takes 154 hours to produce a cylinder with an inner diameter of 420 mm and a length of 12 meters by the traditional method, and it takes only 4 minutes to produce by the cold drawing method.
2. High pass rate: Because the rolling head of the boring hole also serves as a guide, during the cutting process, the blank tube deflects due to its own weight, which causes the rolling head and the boring cutter to deviate, resulting in waste products. The pass rate can only reach about 60%, and the cold pass method can produce a pass rate of 95%.
