One of the devices for butt welding of polymer pipes

The kit includes an electromechanical end facer - a two-sided disk knife, simultaneously bringing the ends of the pipes to an ideal condition. The end facer can be removable, in the form of a separate block, or folding, on a hinged joint.

After the cleaning stage, the end face is removed and a flat round heating element is installed in its place between the two pipes, which ensures the heating and the beginning of the melting of the material. The heater can also be completely removable or hinged.

The next step is the compression phase – the heater is czech republic mobile database (folded back), and the movable blocks with clamped pipes move towards each other. The required force can be provided by hydraulics or mechanical transmission – worm, screw, lever, etc.

Various models of devices for butt welding of polypropylene and polyethylene pipes

Such devices vary in size and type of power drive, can be universal or designed for a certain range of pipe diameters. They have a common feature - high cost, which makes their use in domestic conditions completely unprofitable. And there is no need for this - for the installation of any pressure and non-pressure pipelines in a house or apartment, coupling welding is quite sufficient, especially since for short sections it is the optimal solution, and the quality of the connections is even higher.

Machines for manual coupling welding
And this is exactly the equipment that will be useful to a home craftsman when creating or reconstructing a home plumbing or heating system. As already noted, a mechanical drive is not required - human muscular effort is enough. Therefore, the design of the device itself is extremely simple.

The most common diagram of the device for welding polypropylene pipes

Each device has a handle (pos. 1) to enable welding operations to be carried out while suspended, in hard-to-reach places. As a rule, a cable (pos. 2) comes out of the handle to connect to a 220 V power supply.
