The continuous shaft twisting J-C-O (J-ing, C-ing and O-ing) process is adopted, which has the characteristics of high forming accuracy, high efficiency and uniform forming stress distribution. The outer diameter of the production specification is Φ356~Φ1626mm, the wall thickness is 6~50mm,It is mainly used for transportation pipes for various purposes such as petroleum, chemical industry, natural gas, electricity, city gas, water supply and drainage, and is also widely used in construction, bridges, docks and other engineering fields.
