- 摘要:
- 本文介绍的三通成型新工艺是以无缝钢管作管坯、以天然气－氧气混合气体为燃料，利用瓦形气体火焰加热图将管坯局部加热，然后在专用设备上对管坯进行推压热拔而一次成型工艺技术。这种新工艺特别适合在有天然气源的施工单位推广应用，其产品的优点是铸造成焊接三通所难以相比的。
It introduces a new technique of seamless tee forming. It takes a segment of seamless pipe as blank piece and heats a part of the blank piece by means of natural gas and oxygen flame heating ring. And then the heated blank piece is formed into tee joint once a time through course of pushing, pressing and heat drawing. This technique is specially suitable for fabricator who has a gas source nearby. This new tee product has excellent advantages which the cast tee and welded tee products hardly match with.1999,2(2): 37-38 收稿日期：1998-10-7
