PE pipe fittings are non-toxic, hygienic, corrosion-resistant, non-leakage, small flow resistance, high toughness, excellent flexibility, good resistance to rapid cracking, long service life, easy recycling, easy to install.
PE pipe fittings can be used for water supply pipes, gas pipes, coal mine pipes, oil pipelines.
Polyethylene (PE) water supply pipe and pipe fittings
1, socket type hot melt connection
The outer surface of the tube end and the surface of the socket are simultaneously heated to the melting temperature of the material. After checking the shape of the nozzle, the end of the molten tube is inserted into the socket and fixed until the interface is cooled. This connection is suitable for pipes with a pipe diameter of less than 125 mm.
2, hot docking
The two end faces perpendicular to the tube axis are brought into contact with the hot plate, so that the both end faces of the pipe reach the melting temperature, and the both end faces are pressed and connected, and a certain pressure is applied for a predetermined time and then the interface is cooled. This connection is suitable for the connection of pipes of the same pipe diameter to the pipe fittings.
3. Electrofusion welding
After the pipe fittings are inserted, the heating element is heated at a set current, and the joint portion of the pipe and the pipe is heated, melted, bonded, and the connection is completed after cooling.
