LiSeven polypropylene pipes, manufactured in Ukraine, reinforced with fiberglass or aluminum, are used for installation of hot and cold water supply, heating and ventilation systems.

The PP-R / PP-RCT system of pipes and fittings from the manufacturer PipeLife (Czech Republic) is designed for water supply and high-temperature heating systems.

The corrugated sleeve is used to protect water pipes from mechanical damage during internal (hidden) installation and protects the external surface of the pipe from the chemical influence of cement / concrete, and also performs a compensatory function when the pipe expands.
