Electrocoupler HDPE 50mm used widely today in the European market for joining the pipes in the water supply lines, natural gas lines and sanitary discharges. This electrocoupler mounted by the electro-fusion method. Electrocoupler enables joining of HDPE pipe, different fittings HDPE by each other and network. For welding elecrocupling using a welding machinery which supplies power to control reziztencën of electrocupler, this resistance generates heat needed the union by merging the inside part of electrocoupler and exterior of HDPE pipe. Manufactured with European standards, resistant to corrosive materials, high resistance to deformation of land and resistant to pressure up to 16 Bar.
