Technical characteristics:
The PVC-U sewage pipe system is produced in the diameter range DN/OD 110 – 500 mm and in the stiffness SN2, SN4, SN8, SN12. The pipes for outer sewage system are orange-brown (RAL 8023), uniform in terms of shades and intensities with a smooth outer and inner surface. All types of sewer pipes and fittings are connected between each other and with smooth-wall pipes through sockets with a groove in which an elastomer seal is placed.
Standards:
EN 1401-1:2009 – Plastics piping systems for non-pressure underground drainage and sewerage — Unplasticized poly(vinyl chloride) (PVC-U) — Part 1: specifications for pipes, fittings and the system
EN 13476-2 – Plastics piping systems for non-pressure underground drainage and sewerage — Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) — Part 2: Specifications for pipes and fittings with smooth internal and external surface and the system, Type A
Advantages of PVC-U pipes and fittings:
Full tightness
High smoothness of the inner surface of the pipes
High abrasion resistance
Total corrosion resistance of pipe surfaces
High chemical resistance to substances in the pH range from pH 2 – pH 12
Significant reduction in the weight of PVC-U pipes in relation to stoneware, concrete and cast iron pipes
Significant chemical resistance to many chemicals substances
A large selection of pipes with adequate stiffness
Application in communication engineering
