    • Jointing systems for plastics pipes are known where electrofusion is employed to create a welded joint between two pipe ends. Conventional electrofusion units work well on pipes of small diameter, below 400mm, but with larger diameters difficulties arise. The invention seeks to overcome difficulties of joining large diameter pipes, an objective met by a jointing system comprising a strip of plastics material wound with a resistance wire, and a containment strip of a compatible plastics material. Both of the wound strip and the containment strip can have a tightening means such that with the wound strip wrapped around a pipe joint, and the containment strip wrapped around the wound strip, both can be tightened onto the pipe ends at the position of the joint. Once fusion has taken place, the wound strip and the containment strip are welded together onto the pipe ends to create a sealed joint in the form of a hoop of high strength.
    • 已知用于塑料管的接合系统,其中使用电熔体在两个管端之间形成焊接接头。 常规的电融合单元在小直径小于400mm的管道上工作良好,但是直径较大的问题出现。 本发明寻求克服连接大直径管道的困难,其目的是通过一种接合系统来实现,该接合系统包括缠绕有电阻丝的塑料材料条和相容塑料材料的容纳条。 伤口条和容纳带两者都可以具有紧固装置,使得缠绕在管接头周围的缠绕条以及缠绕在伤口条周围的容纳条可以在接头的位置处紧固到管端上 。 一旦发生熔合,将伤口条和容纳条焊接在管端上,以形成高强度箍形式的密封接头。
