Product Details

 HDPE Pipe and Fitting is a polyethylene plastic. In the 1990s, it began to develop vigorously in our country, with continuous improvement of quality. It has now been widely used in architectural water supply, urban water supply and other aspects. In recent years of engineering practice and application, the advantages of PE pipe have been affirmed by the construction personnel, it overcomes the shortcomings of easy rust, scaling, bacteria, short life, corrosion resistance, light quality, easy recycling and many other advantages.


Connection Methods for  HDPE Pipe and Fittings

PE tube is the most convenient hot melt connection, electric melt connection, socket connection. Hot melt connection is divided into hot melt socket connection and hot melt butt connection.

(1) Hot melt socket connection is to heat the matching inner surface and outer surface into a flow state at the same time, remove the heating tool, and insert the outer surface into the inner surface to form socket lap. Adjust the position of pipes and fittings so that the pipes and fittings are on the same axis to prevent the eccentric welding joints from being firm and the air tightness is not good. Because PE street only after all cooling to room temperature can achieve the best heat resistance strength, cooling period of other external forces will make pipe, pipe fittings can not maintain the same axis, thus affecting the quality of welding, therefore, cooling period shall not be moved to be connected or apply external forces at the connection.

(2) Hot melt butt connection, that is, two of the same connecting surface with a heating plate to the powder flow state, remove the hot plate to apply pressure to the connecting surface, and under this pressure, cooling fixed, forming a firm connection. The key to this connection is timing, temperature, and pressure.

(3) PE pipe with different diameter limits shall be connected by reducing the diameter of PE pipe fittings, and then hot-melt connection shall be adopted. For the connection of PE pipe with DN>50 and other pipe pipes, valves, expanders, fire hydrants and other metal pipe fittings, the same type of flange shall be used to connect the PE pipe with DN<50 and metal pipe and small-diameter valve, and the injection pipe fittings with metal threads inside and outside shall be used for the transition. The pressure grade of the transition fitting shall not be lower than the nominal pressure of the pipe.
