PVC-U pipes – characteristics

Pressure water pipes are made of polyvinyl chloride (PVC-U) – a material with extreme resistance to corrosion and chemicals. These products meet strict quality, assembly, environmental and operational standards. PVC pipes have a uniform structure and smooth external and internal walls. At the end of the pipe there is a special socket with a groove adapted for the installation of a seal. Seals for pressure pipes are characterized by increased resistance to overpressure and underpressure.

Advantages of PVC-U pressure pipe and fitting systems

The PVC-U pressure pipe and fitting system guarantees:

ease of installation – the system is lightweight and does not require the use of specialist tools;
easy transport thanks to low specific gravity (for comparison, a steel or cast iron system is up to 7 times heavier);
durability of at least 50 years;
maximum resistance to internal and external corrosion, constant high temperatures (up to +60°C) and chemicals - without the need to use additional protective coatings;
consistent performance – PVC pipes are resistant to sediment build-up, which prevents reduction of internal cross-sections;
tightness of connections; • trouble-free operation;
safety for humans and the natural environment, confirmed by the PZH certificate;
low energy consumption for pumping water, thanks to the smooth inner surfaces of the pipes.

Application of PVC pressure pipes

PVC-U pressure pipes are used to build pressure and vacuum systems transporting various types of liquids: from municipal sewage and sewage with extreme pH values, through rainwater, surface water and groundwater, to treated drinking water. They are not suitable only for transporting liquids that have a destructive effect on PVC-U and EPDM rubber, from which the seals of socket connections are made. The most common applications of PVC pipe systems are:

underground water supply networks,
above-ground external and internal water transmission systems,
underground and above-ground pressure drainage and sewage systems,
sewage systems in areas affected by mining damage (variants of pipes with an elongated socket).
