管材弯曲工艺及常见缺陷预防

Bending technology of pipe and the prevention of its common failures

介绍了绕弯、推弯、压弯、滚弯等几种生产中常见的管材弯曲工艺,并对实际弯曲常见的质量缺陷及预防措施进行了分析阐述,从而减轻或消除缺陷的产生,以获得较好的弯制管件。

The article introduces several common pipe bending technologies in production as reel,push,press and roll bending,and analyzes and illustrates quality failures of practical bending and their preventive measures,in order to reduce or avoid failures and to gain well bended pipe fitting.
