Hello today we will talk about the various types of union with which the polyethylene pipe is the most traditional method by means of thermofusion.

This method consists of cutting the pipe at its ends, so that it is aligned and then by an iron, at a controlled temperature, according to the diameter and thickness, the mechanical connection is made to join one tube with another and ensure the tightness of the tubes Which are cast in one piece.

Electrofusion:
This consists of another system, which is equally efficient, it is necessary to have the special equipment to make this union, which is programmed to read (barcode scanner) which will indicate current time to run, by resistors Achieving the welding.

Flanges:
The pipe has the end flanges that are thermofused, in factory or in the field, once the thermofusion is done, it is only necessary to join with screws and to add gaskets. This method is also common to join, with valves or connections of cast iron. (Magnets, tubes and fittings, valves).

Coupling to socket:
This union, is safe and efficient practice is used in smaller diameters mainly used as the main method of joining in polypropylene pipe for PPL building.
Thermofusion coupling to socket.
These 4 methods mentioned above are mostly used for water conduction.

Compression Couplings:
This method is mainly used in connection of polyethylene pipe for conducting wiring (Power). It also exists for water conduction but they are not common, which installers prefer other methods.
