JOCE Molding Process Production Line 

Adopts continuous axis contorting J-C-O(J-ing, C-ing and O-ing)process with characteristics of high forming accuracy and efficiency as well as balanced distribution of forming stress.Which can produce straight seam welded pipe with OD: Φ356~Φ1626mm,WT:6~50mm. The main equipment such as pre-bending is provided by Tianshui forging and pressing machine. The pre-welding adopts high-power CO2 gas shielded welding and high-speed full-length pre-welding process. It adopts Lincoln multi-wire DC/AC automatic submerged arc welding machine, and is equipped with steel plate automatic flame cutting machine, steel pipe straightening machine, steel pipe finishing machine, and steel plate online manual UT flaw detection. It is mainly used for transportation pipes for petroleum, chemical, natural gas, electric power, city gas, water supply and drainage, etc. It is also widely used in construction, bridges, wharfs and other engineering fields.
