Pipe connectionThe ways of connecting HDPE pipes can be divided into electro-fusion and butt fusion.
The general principle of HDPE pipe welding is that the polyethylene is melting from 190℃ to 240℃, then if the melt pipes can be fully connected with proper pressure after cooling. HDPE pipes can be connected with other material of pipes and parts, such as cast iron pipes, valves and fittings etc through proper use of flanges or HDPE/steel transition connecting fittings.
