PE Pipe Welding, PE Pipe Butt Welding, This method offers high reliability and diameter in the range and pressure of the process: the pipe ends are heated, using a tool called a “mirror image” which defines the contact pressure and temperature. During cooling, the ends are quickly contacted and held under pressure.

Polyethylene pipes include MDPE and HDPE pipes. Based on wall thickness, they are categorized into the SDR11 and SDR17.6 series. The former is suitable for the transportation of gaseous manufactured gases, natural gas and liquefied petroleum gas, while the latter is mainly used for the transportation of natural gas. Compared with steel pipes, the construction process is simple and flexible. What's more, there is no need to treat it with anti-corrosion treatment, which will save a lot of processes. The disadvantage is that the equipment is not as good as steel pipe. In the construction process, special attention should be paid to the safe spacing of the heating, not exposed to sunlight in the air, and sensitive to chemicals to prevent damage caused by leakage of sewage pipes. pe vacuum sheathing pipe production line editorial briefly explains the classification of PE pipe.


Plastic pipe equipment according to the production method of pipe fittings: injection fittings and welding fittings.

According to the construction method and application classification: electro-thermal fusion fittings, thermal fusion butt fittings, socket fittings and steel-plastic adapters.

According to engineering habits:casing, elbow, tee, saddle tee, reducer, end plug, flange, steel-plastic conversion.

According to the pressure level, PE pipes are mainly divided into 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, 1.6MPa, MPa is the unit of pressure, e.g., 0.6MPa is the meaning of pressure 6 kg.
