Soldering polypropylene pipes for heating systems
Now more and more used pipes,made of different polymeric materials. Polypropylene is one of them. This type of pipe 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.
Consider the main 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 you have installed all the elements in place, you can start harvesting. 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.
At 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. Joint is made on special labels to avoid possible twists.
Soldering of polypropylene pipes is the finalstage. 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 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 with what soldering technologypolypropylene pipes, all more or less clear, then we should consider other points. For the heating system and hot water supply is not every pipe.
For heating systems, a speciala kind of material, 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 products made of polypropylene,designed for heating systems, meet special technical requirements and are approved for use in hot water supply systems, metal parts are suitable for this purpose much better, 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 working.
