Propylene pipes for heating: types and properties

Pipes

Recently, modern construction materials have begun to appear, which, thanks to their qualities, are actively replacing old and familiar products. Such changes did not bypass the area of creating pipelines for various purposes, thanks to which a modern CP pipe for heating has a number of positive qualities that make the system more reliable and functional.

Characteristics and installation

To begin with, it is worth mentioning at once that we will be talking about special materials that are designed specifically for these purposes. The fact is that there are PP pipes for heating, differing in their target characteristics and scope. Therefore, plumbing products will not be considered.

Particularly popular in this area are multilayer or reinforced materials that not only have good thermal conductivity, but also have high strength

Special features

First of all, it should be noted that such materials are not exposed to corrosion.. At the same time, polypropylene pipes for heating can work with a wide variety of compositions and even some acid and alkaline substances are excellently tolerated.

It is also important to mention that this type of material has a very long life.. Some of its species can work without replacement for more than fifty years.
The fact that the internal surface of the flow tube for heating is almost perfectly smooth and in the process of operation does not collect any sort of plaque on itself deserves special attention.. That is why the permeability of fluid in such systems is very high, which is important for closed cycles that do not use forced feed or reduce it to a minimum.

Quite often, for such work, products with compression locks on the fitting were used, but professionals argue that such a connection in these systems cannot have a sufficient level of reliability.

Some types of such products have fairly good strength and resistance to temperature extremes.. At the same time, this material has heat conductivity, which is ideally suited for the chosen field of operation.

Tip! When choosing this product, first of all, you should pay attention to the temperature regime at which a particular model can work. Usually it is indicated directly on the pipe and is selected in accordance with the type of domestic boiler for the heating system and its capacity.

The solder tube is actually a monolithic structure that can withstand much greater pressure at the joints than in a normal place.

Installation

In recent years, pipelines reinforced for heating have become particularly popular. However, their method of installation is practically no different from the one used for working with similar products. Usually it consists in soldering, which is produced using a special tool.

Special soldering iron, which is used when working with such material

Usually, a part of the pipe and the fitting are heated with a soldering iron with appropriate nozzles. After this, the parts are joined and retained for a certain time required for cooling. It should be noted that with a little preparation, this process can be done by hand, which is another advantage of these pipes.

Some systems are quite complex and before starting work it is always necessary to have a ready project for which they will be executed.

Professional craftsmen first try to make a test soldering in order to choose the mode necessary for the work. Therefore, they acquire in advance several additional fittings for pipes and pipe fragments.

Tip! If the work is done once, then it makes no sense to buy a soldering iron. Many stores offer to rent this tool, and if large purchases of building materials are made, this service can be attached as a discount.

Transitions of such pipes through ceilings or walls need to be thought out very carefully, because when heated they expand a little, which means there should not be tight contact.

Recommendations of specialists

It is necessary to choose the type of pipe and the material of its manufacture at the design stage. In this case, the installation manual does not advise making an independent replacement of the material, as this may violate the functional features of the design.

If such pipes are laid on the street, then you should use a special thermal insulation. However, professionals advise to place them below the level of soil freezing.
It should be noted that the price of systems based on such pipes practically does not differ from metal constructions. However, they are much cheaper than copper or stainless steel products.

Sometimes when working with such material it is easier to use special inserts or connecting elements.

Conclusion

After studying the video, proposed in this article, it is necessary to conclude that this type of material is very popular recently and is actively used by modern builders. Also based on the presented text, it is worth saying that the pipes made from this material have a number of positive qualities that should be considered when choosing.
