U-ing-O-ing-Expanding (UOE),the main process for making longitudinal submerged arc welded pipe(LSAW) with steel plate,is famous for its superior quality and reliability.Based on the famous non-linear finite element analysis (FEA) software MSC.Marc,a finite element model (FEM) has been established to simulate the whole UOE forming process by using the secondary development technology with the Python language.Research has also been conducted systematically on the crimping,U-ing,O-ing and mechanical expanding processes.The practice has shown that the simulation calculation is in close conformity with the actual site production data.The FEM has been successfully applied in the UOE production at Baosteel.
