There are two methods for joining HDPE pipes. Butt Welding, Electrofusion Welding, or mechanical fasteners are used to connect HDPE Pipe. Pipes made of materials other than polyethylene can be connected using compression fittings, flanges, or other suitable adapters. Connection parts provide convenience based on where they will be used.
Welding is done with heating resistors inside the fusion fitting during the electrofusion welding process. After the pipes are inserted into the Ef fittings, the welding machine's ends are connected to the resistors of the Ef fitting and heated. As a result, the HDPE pipe will be connected to the electrofusion fitting. Pe 100 pipes can be welded using the Electrofusion welding method with HDPE pipes ranging in diameter from 20 mm to 1200 mm. The DVS 2207 standard is followed when performing electrofusion welding.
Butt welding is the most commonly used welding method for joining HDPE pipes and fittings today. The pipe joining method is a process in which the two ends of the pipes are heated and welded using a butt-welding machine, and then pushed toward each other by pressure at a specific temperature The welding method can be used to join HDPE pipes with diameters up to 1200 mm. The butt-welding method adheres to the DVS 2207 standard.
