Soldering polypropylene pipes for heating systems

Now increasingly using pipes made of different polymer materials. Polypropylene is one of them. This kind of pipes is easy enough to process. Having a special apparatus for soldering polypropylene pipes, it is possible to mount a heating or water supply system quickly and without special difficulties in a short period of time.

Let's consider the basic stages of installing a heating system using this type of material, as well as how to solder polypropylene pipes.

The first step is planning. It is necessary to choose the places of fastening of radiators, the total length of pipelines, as well as individual lengths of pipes. At the second stage, the preparatory work is carried out. After installing all the elements in the places you can start harvesting works. Pipes are sawn after all measurements are taken. Next, you will need to purchase the necessary number of fittings, tees, couplings and other auxiliary parts. Soldering of polypropylene pipes is realized only after they have been removed from the reinforcement layer by means of a special device.

In the third stage, the parts are joined. Piping from this type of material is an organic compound based on welding seams, so it is important to observe the linear and radial mating of all elements. The joint is made by special marks to avoid possible twists.

Soldering of polypropylene pipes is the final stage. Individual elements are preliminarily heated to a certain temperature, after which they are mated. After the final hardening of the node, you can proceed to the docking of the next one. Polypropylene parts are heated for a certain time, which depends on the thickness of the walls and the diameter. In this process, it is very important to take into account the ambient temperature.

So, if the technology of soldering polypropylene pipes is more or less clear, then other points should be considered. For the heating system and hot water supply is not every pipe.

For heating systems, a special kind of material is used, the hallmark of which is almost the same expansion ratio with steel pipelines. Such pipes are capable of passing water, which is heated to 95 degrees Celsius. The reinforcement layer is used specifically to obtain low expansions in polypropylene products. It can be fiberglass or thin aluminum foil.

While all polypropylene products designed for heating systems comply with special specifications and are approved for use in hot water supply systems, metal parts are much more suitable for this purpose, as long as there is no polyethylene material that is able to exceed the linear expansion features for steel .

So, now you know how the soldering of polypropylene pipes is carried out, and also what is needed for this. Now you can start work.
