聚乙烯套管现场焊接技术的研究

Research on Welding Technology of PE Casing Pipe in Site.

本文首先对电阻丝带熔焊和热风焊接作了系统分析,进而提出以电阻丝带熔焊作为连接强度保证,以聚乙烯(PE)焊条和热风焊提高连接密封性的实用补口焊接技术。该方法设备简单、成本低廉,灵活方便。

In this article, the author first gives the systematic analysis of resistance wire-belt fusion weld- ing and hot air welding, and then raises a pratical welding technology for jionts coating which can guarantee the bonding strength by applying the resistance wire-belt and ean increase the sealing property of the joints by using the PE electrode and hot air welding. This method has the advan- tage of less equipment requirements, low cost and more flexibility.
