PE Ball Valve Series

Properties of HDPE Valve: High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic made from petroleum.

Installation & Testing

Hot melt butt installation:

①Clean the heating plate, set the heating temperature to 220+10℃, and keep it warm for ten minutes

②Fix the pipes to be welded (pipe fittings)

③ Use a milling cutter to mill the end face of the pipe (pipe fitting)

④Check the coaxiality of the pipe

⑤Butt the pipe and the pipe, keep the pressure for 15 minutes, until the pipe is cooled

⑥The pipe and the heating plate collide with each other, forming a flanging around the pipe, the pressure drops to 0, and it starts to absorb heat, and the time is 10-12 times the wall thickness

Electrofusion installation:

① Before welding, select the appropriate welding voltage according to the marking parameters on the pipe fittings, the voltages are 220V and 380V

②Clean the pipe

③Identification insertion length

④Scrape off the oxide layer

⑤Clean the pipe

⑥Assembly

⑦Welding
