VALPlast multilayer pipes made of high modulus polypropylene (PP-HM) are used in external networks for the collection and transport of sewage and stormwater in localities.

Product standard: SR EN 13476-2 "Plastic piping systems for discharge and sewerage, non-pressure, underground. Structured-wall piping systems of unplasticized polyvinyl chloride (PVC-U), polypropylene (PP), and polyethylene (PE). Part 2: Specifications for pipes and fittings with smooth internal and external surfaces and for the system, Type A."

The pipes have an intermediate layer of PP-B (block copolymer) located between an outer layer and an inner layer of compact PP-HM material. The pipes are manufactured by co-extrusion.

The pipes are chamfered at both ends and are joined with a socket and sealing gasket, which is supplied with the pipe.

Depending on the strength class, the pipes are classified:
– SN8 with minimum ring stiffness 8kN/m2;
– SN10 with minimum ring stiffness 10kN/m2.
