One of the most important activities of the plant «Spiroplast» is the production of polypropylene pipes.
Polypropylene does not support combustion, lightweight and high impact resistance, especially at low temperatures.
Polypropylene – the only material from which the pipe does not break the freezing of water.
However, the main advantage of the material is low cost compared to other materials. Therefore, in recent polypropylene tubes were used widely in the private and capital construction.

Polypropylene Pipes «Spiroplast» can be used in all water systems – for hot and cold potable water and process water, for arrangement of underfloor heating, wiring heating systems.
Due to the chemical resistance of polypropylene pipes brilliantly proved in the food and chemical industry, widely used in gardening associations, at gas stations.
Professionals, designs penstock PP must take into account the likely operating conditions, as well as prolonged exposure to heat and pressure of the transported fluid.
