管道压接技术的机理及主要参数的计算

Principle of Pressure-connecting Technology of Pipeline and Calculating Methods of its Main Parameters

管道压接技术,是一种既不破坏内涂层,又不需要内补口的内防腐管道连接技术。本文介绍了管道压接技术的机理及压接过盈量、胀头锥角、扩口胀力等参数的计算方法。

The pressure-connecting technology of pipeline neither destroys the inner protecting layer, nor needs inner repair for inner preservation of pipeline. This paper introduces the principle of pressure-connecting technology of pipeline and the calculating methods for these parameters, such as excess amount of pessure-connecting, angle of expansion head and expanding force etc.
