Abstract

Disclosed herein is a device and method, preventing water from leaking to the outside of a multiple wall pipe, or a hollow part in a pipe wall, and forcibly correcting differences in inside and outside diameters between pipes provided on opposite ends of a joint, and simultaneously correcting circularity of the pipe. The heat plate includes a disc, a circular groove provided on an outer surface of a side of the disc and having a V-shaped cross-section with a flat bottom, and a heat source inserted in the disc. A method of joining a multiple wall pipe includes inserting an end of the cut multiple wall pipe into a V-shaped groove of the heat plate, heating and fusing the end of the cut multiple wall pipe by applying electricity to the heat plate, and compressing and cooling the cut multiple wall pipe after the heat plate is removed.
本发明公开了一种装置和方法,其防止水泄漏到多壁管的外部,或管壁内的空心部分,并强制性校正位于接头的相反端上的管之间的内径和外径差异,同时校正管的圆度。加热板包括圆盘、位于圆盘一侧的外表面上并具有底部平坦的V形横截面的圆形凹槽以及插入圆盘中的热源。接合多壁管的方法包括:将切割后的多壁管的一端插入加热板的V形凹槽中;通过将电施加到加热板上而加热和熔化切割后的多壁管的该端;在取走加热板之后压缩和冷却切割后的多壁管。
