Now, pipes made of different polymeric materials are being increasingly used . Polypropylene is one of them. This type of pipe is quite simple to handle. Having a special apparatus for soldering polypropylene pipes, you can quickly and easily install a heating or plumbing system in a fairly short 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 the layout. You should choose the location of the radiators, the total length of the pipelines, as well as individual pipe sections. At the second stage, preparatory work is carried out. After installing all the elements in places, you can proceed to the procurement work. Pipes are cut after all measurements have been carried out. Next, you will need to purchase the necessary quantity of fittings, tees, couplings and other auxiliary parts. Soldering of polypropylene pipes is realized only after the reinforcing layer is removed from them by means of a special device.
At the third stage, the parts are docked. A pipeline of this type of material is an organic compound based on
welds, so it is important to observe the linear and radial alignment of all elements. The joint is made according to special marks in order to avoid possible twists.
Soldering polypropylene pipes is the final step. Individual elements are preliminarily subjected to heating to a certain temperature, after which they are docked. After the final solidification of the node, you can proceed to dock the next one. Polypropylene parts heat up for a certain time, which depends on the wall thickness and diameter. In this process, it is very important to consider the ambient temperature.
So, if everything is more or less clear with what the technology of soldering polypropylene pipes is, then other points should be considered. Not every pipe is suitable for a heating system and hot water supply .
For heating systems, a special kind of material is used, the hallmark of which is almost the same expansion coefficient with steel pipelines. Such pipes are capable of passing water that is heated to 95 degrees Celsius. The reinforcing layer is used specifically to obtain low expansion rates in polypropylene products. It can be fiberglass or thin aluminum foil.
Despite the fact that all polypropylene products intended for heating systems comply with special specifications and are approved for use in hot water supply systems, metal parts are much better for these purposes, as long as there is no polyethylene material that can exceed linear expansion features for steel .
So, now you know how to solder polypropylene pipes, and also what is needed for this. Now you can get to work.
