Electrofusion welding is a method for joining High-Density Polyethylene (HDPE) pipes that utilise electricity and heat to meld the fitting together with the pipe. Pipes that transport liquid and gas use this method, ensuring tighter connections and preventing leaks.
The entire electrofusion process is as follows: First, fittings are clamped in place to join the two connecting pipes. The electrofusion welder will then be programmed to send electric currents into the fitting via the cable tips. The currents will cause the pipes and fittings to melt together, at a temperature advised by trained operators. The pipes are locked into place once the joints have cooled.
Using poly electrofusion joint fittings offers the following advantages:
Strength of Connection
Whole pipe systems malfunction with the failure of a single joint. Melting the surfaces of both the pipe and the fitting creates a better-integrated pipe system, effectively transforming the joint into a part of the pipe. This integration reduces the pressure on the joints, thereby increasing pipe durability and joint reliability.
Ease of Installation
Electrofusion welding is automated, which helps reduce installation time and allow for greater versatility. This method provides an advantage in industrial operations and repairs, where installations are still convenient even in areas that are tighter than usual. The automation also ensures that the installation follows proper temperature and exact heating time, minimising possible mistakes.
Joint Record Management
Welding equipment keep data regarding all joint installations, making problem areas traceable in case of potential pipe failure. The recorded data ensures consistent quality for all pipe installations, with some welders able to store more than 100,000 joints in their memory capacity. Joint records also help lower the cost of future repairs and maintenance by providing reliable information for inspections and planning.
Electrofusion welding provides increased efficiency and quality for the installation of HDPE joints. Professionally-trained operators are needed to fully maximise these benefits, helping ensure the integrity and longevity of any pipe system.
