High pressure welding. Worldpoly 8/16 High Pressure is a hydraulically operated butt-welding machine suitable for PE 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.
