How to connect PE water supply pipe fittings

We know that PE water supply pipe manufacturers in the application of pe water supply pipe pipe is usually due to the field must and its standards are not the same, will carry out its connection application, and often applied to the water pipe people understand that in the case of water pipe connection, there will be many different methods to carry out practical operation, such as hot melt connection and electric melt pipe connection. As everyone knows, the two kinds of connection are divided into many different methods, but the method often used is also hot melt connection, in order to better connect the actual operation, everyone together to understand what the detailed connection method is like. 1. Prepare raw materials in advance: Place the PE water pipe or pipe fittings in the leveling part and place them on the docking machine, leaving enough turning capacity of 10-20 mm. 2, clamping: according to the electric welding of pipe fittings, pipe fittings to select the appropriate tile fixture, clamping pipe fittings, for the turning to be fully prepared. 3. Turning: turning the welded steel pipe segment, pipe fitting inner hole residue and air oxide layer to ensure that the two connected inner holes are smooth, smooth and free of impurities. 4, PE water supply pipe fitting alignment: two welded steel pipe segment holes should be thoroughly aligned, the lower the fault, the better, the fault can not exceed 10% of the wall thickness. Otherwise, it will interfere with the connection quality. 5, heating: the connection temperature is usually in the middle of 210-230 ° C is appropriate, the heating plate heating time is different throughout the year, and the melting length of the two heads is 1-2 mm. 6, conversion: Take the heating plate away, quickly let the two hot melt end face stick and pressure, in order to ensure the quality of melting connection, the smaller the conversion time, the better. 7, melting connection: is the important welding welding, the whole process of connection should always be under the pressure of melting, the total width of 2 sides of the roll to 2-4 mm is appropriate. 8, refrigeration: maintain the pressure of the connection will not change, so that the PE water supply pipe connector slowly cooling, cooling time length
