Scope
Pipes are intended for construction of self-flowing tight pipelines of the household and rain sewerage. They are used mainly in the design of new drainage systems, which at the beginning of operation will not be fully filled.

The Qmax PLAST pipe is a hermetic reinforced concrete pipe with a flat support. Greater ability to self-clean at small flows, in comparison with round pipes.

Plast pipes are reinforced concrete pressureless pipes with protective shells made of polyethylene. The protective sheath is made of low pressure polyethylene (LDPE) according to GOST 16338-85, designed to ensure durability (at least 50 years) and waterproofing of sewer pipes during operation in conditions of action inside the pipes of highly aggressive environment to concrete (reinforced concrete). PNT is resistant to concentrated hydrochloric, carboxylic and fusible acids, oils, fats, alkalis, salt solutions, resistant to gasoline, low temperatures, ductile and has good impact resistance.
