HDPE pipes are mainly used for: municipal engineering water supply system, building indoor water supply system, outdoor buried water supply system and residential area, factory area buried water supply system, old pipeline repair, water treatment engineering pipeline system, gardening, irrigation and other fields of industry Water pipes, etc.
But it should be noted that HDPE pipes cannot be used for hot water pipes.
HDPE pipe specifications and connection methods
The diameter of HDPE pipe ranges from DN32 to DN1000, and is divided into 26 levels. The pressure level is between 0.6Mpa and 1.6Mpa, a total of 5 levels.
HDPE pipe will be melted between 190℃n240℃. With this feature, the two melted parts of the pipe (or fittings) can be fully contacted and maintained at proper pressure. After cooling, the two can be firmly integrated. Therefore, the connection method of the PE pipe is different from that
of the U-PVC pipe. It usually adopts two methods of electric hot melt connection and hot melt butt connection. According to the size of the pipe, it can be divided into: when DN≤63, injection hot melt socket connection is used; When DN≥75, use hot melt butt connection or electrofusion socket connection; when connecting with different materials, use flange or threaded connection.
In the pipeline repair method, there are pipe expansion construction method and lining HDPE method.
