The research and production holding JSC TMIM mastered release of corrosion-proof VRS from polypropylene pipes with bell-shaped nozzles.

Water distribution system from polypropylene pipes of variable section with bell-shaped nozzles. The material of pipelines excludes formation of deposits on an internal surface, has smaller coefficient of friction and isn't subject to corrosion. Also it is necessary to refer durability to advantages of polypropylene pipes, ability to maintain short-term temperature increase of the carrier to 95 °C, the small weight, lack of electric conductivity, good technological effectiveness of production and installation.

Polypropylene is chemically unreceptive to many hostile environment, is eco-friendly, is easily washed out in use, keeping hygienic properties during all service life which according to all standards of construction makes 50 years.
