High & Low pressure welding. Worldpoly 8/16 High Pressure is a hydraulically operated butt-welding machine suitable for PE and PP pipes and fittings from 8" to 16" IPS. using the high pressure welding methods specified by ASTM. ISO and Aus/NZ. Excellent Australian Engineered design and construction provides a premium machine for welding both on the worksite and in the factory. The use of high quality pressure-cast Aluminium clamps allows for lower weight without compromising strength and performance. while providing extra strength when welding out-of-round pipe. Significantly increased force is available for drag when welding pipe strings. or on difficult sites. Welding can be carried out between clamps 3 & 4 for tees. bends and manifold work. and the machine is pre-wired for immediate integration with optional data Logger. and overhead electric crane.
