大口径三通翻边成形工艺研究

Research on Fabricating Large Diameter Tee by Flanging Forming

主要阐述了三通翻边成形的新工艺方法,并对一种大型等径三通D735×735×735(SA-335P91)进行试制,最终试验结果表明三通翻边成形的方法可以提高三通支管的成形质量,并降低三通的制造成本。该翻边成形工艺可以广泛应用于锅炉、油气管道中大型三通的制造。

The new process of fabricating tee junction by flanging forming is presented and a large tee junction whose pipes of identical diameter,D735×735×735(SA-335P91),is fabricated for verification.The outcomes show that the flanging forming process is in favor of lifting the forming quality of the tee junction and reducing the fabrication cost.The flanging forming process can be widely used in the fabrication of the large tee junctions for boilers and oil pipes.
