WE OFFER THE FOLLOWING ON-SITE WELDING SERVICES
BUTT FUSION AND ELECTRO FUSION WELDING
The two most popular methods of welding HDPE piping are Butt Fusion and Electrofusion welds, these services we can provide for you on-site.
Butt Fusion Welding
The butt fusion technique is a simple one whereby the ends of the pipes to be joined are trimmed square to each other, then heated using a teflon coated heater plate under controlled temperature, time and fusion pressure.
Electrofusion welding involves the use of injection-moulded PE fittings into which the pipes are inserted. Embedded within the fitting is a heating wire (Coil) located just below the surface of the internal bore of the fitting, with terminals on the outside of the fitting for electrical connection. These wires, when energised by a controlled electrical power source for a pre-defined duration, produce the necessary heat to melt the coupler and pipe surfaces in the fusion zone which, once allowed to cool, form a welded joint.
