One of the important and most basic advantages of PPRC pipes and fittings is their simple installation, allowing you to create a tight connection. This is due to the material from which they are made. Polypropylene is a complex polymer that is highly resistant to high temperatures. Therefore, such parts are recommended for hot water and heating systems.
What to consider before choosing, except for high temperature
On the market there is a polypropylene material of various modifications, which has the appropriate marking:
- the block copolymer is labeled as PPV;
- homopolymer - PPG;
- random copolymer - PPR.
So fittings marked PPG are not intended for hot environments. They are often used in cold water supply systems.And if you purchase a material with a similar marking for heating or hot water, then it will not cope with the assigned task.
It is necessary that pipes and fittings withstand temperatures of at least 95 degrees. And for this purpose it is better to choose fittings that belong to the PPV or PPR category.
It is also worth considering that in systems with hot water, the pressure is slightly higher than where cold liquids flow. It is important to pay attention to the marking, which is indicated by two letters PN. It is this abbreviation that recommends the optimal pressure that will not violate the integrity of the product during the service life declared by the manufacturer. And polypropylene products should serve at least 50 years. The pressure in the hot water and heating system must not exceed 25 bar and be below 10 bar.
It is also important to ask the manufacturer who supplies similar products to the market. All products are manufactured in accordance with the requirements of GOST, which is confirmed by international certificates of conformity. If such a document is available, then it confirms the high quality of the product. In general, it is worth noting that a certificate is a kind of quality mark, which was awarded to some groups of goods even under the Union.
Fittings and other fasteners have characteristic design differences:
- the coupling is used when connecting pipes of the same diameter;
- in order to connect pipes of different diameters, you will need transitional couplings;
- if it is necessary to turn, raise the pipeline, you will need a corner;
- where the pipes diverge to the sides, branch out, a tee is required.
If you still have difficulties with the choice, you can take advantage of a free professional consultation.
