Pipes QMAX PLAST are designed for the construction of gravity-flowing sealed pipelines for domestic and stormwater drainage. They are used mainly in the design of new drainage systems that will not be completely filled at the beginning of operation.

The Qmax pipe is a sealed reinforced concrete pipe with a flat backing. Greater self-cleaning ability at low flows compared to round pipes. The pipe is designed to withstand an internal pressure of 0.5 bar (approximately 5 m of water column). It is sealed with an integrated rubber sealing ring and has transport anchors.The pipes are designed for the construction of gravity-flowing sealed pipelines for domestic and stormwater sewers. They are used mainly in the design of new drainage systems that will not be completely filled at the beginning of operation.

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.
