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.<\/p>\n
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.”<\/p>\n
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. <\/p>\n
The pipes are chamfered at both ends and are joined with a socket and sealing gasket, which is supplied with the pipe.<\/p>\n
Depending on the strength class, the pipes are classified:
\u2013 SN8 with minimum ring stiffness 8kN\/m2;
\u2013 SN10 with minimum ring stiffness 10kN\/m2.<\/p>\n","protected":false},"excerpt":{"rendered":"
