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.


Purpose:

  • Under underground pressureless drainage and sewerage systems laid out in the ground in a road lane (under road or off road) or other areas used for communication engineering.

  • For making covers for cables and culverts through road embankments.

  • Dehydration of bridge structures thath are built on road routes.

  • Pipes in the version with elongated socket can be used in mining damage areas.


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
