When installing water supply and heating systems, polypropylene pipes are used, which are presented in the form of a monolithic connection.
They are intended for laying pipelines for various purposes. The supply of drinking water and water intended for technical needs is carried out by a water supply system with pipes made of polypropylene.
A number of advantages allow them to be widely used. Sufficient ease of operation and ease of transportation. They do not need special repair and maintenance. With good resistance to external factors, they have a fairly low cost.
Excellent technical characteristics of polypropylene pipes allow their use in the system of residential buildings and in the construction of industrial facilities.
High hardness forces the installation of pipe systems made of polypropylene to be carried out using fittings. Fittings help prevent bending.
The connection of polypropylene pipes is carried out using combined fittings with threaded metal inserts or using contact thermal welding.
Improved quality indicators of pipes fittings made of polypropylene, undeniably surpassed pipes made of metal used in the heating and water supply system in many technical characteristics.
The technology for manufacturing pipes from polypropylene includes the following process: polypropylene, consisting of granules, is melted in a special cylindrical bunker designed for this purpose. The process is strictly temperature controlled.
Widespread in the construction of pipes made of polypropylene, having the following brands:
Pipes, grades PN10, the service life of which is determined by 45 – 50 years. Cold water supply is carried out by pipes of this brand.
Pipes, grade PN20, whose service life is defined as 25 years or less, are used for cold water supply and hot water supply.
Pipes, grade PN25, due to the reinforced layer on the inner surface, are similar to pipes consisting of metal-plastic. The operation of this type of pipe is directly related to the temperature of the coolant and the pressure in the system itself.
