PVC pipes for street sewerage systems
PVC pipes for street sewerage systems are made of non-softened polyvinyl-chloride, and are designed to collect all kinds of sewage waste waters. The quality of the non-softened polyvinyl-chloride (PVC) used to produce the pipes and the connecting elements, must satisfy the requirements defined by the SRPS G.C6.502 standard. Any use of a softener, a filling or other material that does not possess controlled and attested composition is strictly forbidden.
PVC is a high-quality material, resistant to corrosion and chemical decomposition such as may be caused by acids, alkalis, salt compounds and many other chemicals.
Pipes and connectors made of PVC can be applied as a permanent solution in the temperature conditions ranging from 0 ºC to +60 ºC. PVC installations are resistant to salt water, acids, bases, sulphates, alcohol and mechanic impact. They also provide very good electrical insulation, and have a service life of over 50 years. PVC installations cannot be used for waste waters with a high content of petrol, acetone and benzene. The pipes are joined together using a sleeve joint or other type of connector, with rubber rings ensuring full adhesion.
PVC KK pipes and connecting elements are used in all types of pipelines that are installed below the ground surface, as well as on free and even surfaces above ground level, to be used for collection and removal of waste waters and rainfall, either together or separately. These pipes can be used in industrial wastewater sewage systems, provided that these do not contain elements that can disturb PVC and provided that these are either free-fall (gravity) systems or low-pressure systems. The pipes are produced in S-25 and S-20 series. The choice of the series will depend on the route location and type of base on which the pipes are laid.
The pipes that are intended for street sewage systems are made with an expanded ‘collar’ on one end, or without it (series S-25 and S-20).

The listed diameter of the pipe is its outer diameter, ranging from Ø 160 mm, to Ø 400 mm, while the lengths in which the pipes are supplied range from 1000 mm to 6000 mm.
PVC UK pipes are red-brown in colour (RAL 8023) and bear the inscriptions with the following data: type of material, outer diameter, SRPS G.C6.507, manufacturer’s code and year of production. The quality and the dimensions of the pipe are in compliance with the European Norm EN 1401 and the SRPS G.C6.507 standard.
The useful length of the pipe is its length without the depth of the collar.
