BUTT WELDING MACHINES are used to join lengths of HDPE (high-density polyethylene) pipe, for a variety of construction, gas, mining, water, agricultural and other applications. The new Australian-made PolyForce500 range is capable of joining pipes of up to 500mm diameter and manufacturer Worldpoly has machines catering for pipe diameters ranging from 40mm to 3600mm. The process involves using the machine's hydraulic clamps to secure the ends of each pipe while a heating plate is applied to the ends. When the correct temperature is reached the hydraulic clamps butt both ends together under force, holding them in position while the bonding process takes place to ensure a high-quality seal. The nature of the environments in which butt welding machines are used will often see them operating in remote and demanding locations from early morning to late at night, which is one of the reasons why Worldpoly says it exclusively specified the durable Narva equipment on its latest models. Included in the new machines are two Narva Explora 14" single row LED light bars, four Model 8 LED white marker lamps, a Hi Optics LED rotating beacon and a HDRV surface mount dual USB socket.
