Properties

The three main products are sewage, water mains, drainage and rainwater pipes which their standards are different according to their applications. Sewer pipelines are produced by standard No.9119 (DIN EN 1329) “Plastics piping systems for soil and waste discharge (low and high temperature) within the building structure –Un plasticized poly (vinyl chloride) (PVC-U)”and in diameters 32 to 250 mm. Impact test was evaluated on samples according to ISIRI 9119 “plastics-Unplasticized poly (vinyl chloride) (PVC-U) pipe, fittings and piping system for soil and waste discharge within building structure- specifications. Materials behavior is completely different against impact loads and static loads (like tensile loads). Impact test is an appropriate way to distinguish and classify materials tendency to brittle failures. For more information, related to the product application, please study the attached file. Longitudinal reversion Test was also done according to to ISIRI 9119 “plastics-Unplasticized poly (vinyl chloride) (PVC-U) pipe, fittings and piping system for soil and waste discharge within building structure- specifications”. This test shows the UPVC pipes shrinkage exposed to heat. Since both samples passed the standard, tougher conditions were applied for the test. In order to determine the quality of homogenization of the polymer and additives and also amount of gel in UPVC pipes, the resistance to dichloromethane at a specified temperature test was done. Dichloromethane is a solvent of UPVC. Actually, it is a way to distinguish material chemical and mechanical resistance. The test was carried out according to ISIRI 9119 “plastics-Unplasticized poly (vinyl chloride) (PVC-U) pipe, fittings and piping system for soil and waste discharge within building structure- specifications.

Manufacturer's Description

In most areas sewage pipes are used for removing of homes and industrial areas sewage. They are made of different types of material. Nowadays the most sewage pipes are made by UPVC.Polyvinyl chloride (PVC) is kind of useful plastics in construction and buildings. It can be used in tubes, door and window frames and fittings. By adding lubricants, this material will become softer and more flexible than plastics. If no lubricant and plasticizer is added, UPVC is obtained. Chemical resistance of this polymer make it interesting for variety of industries especially pipe industry. Usage of UPVC includes sewer pipelines, water mains and potable water services, power and telecommunication cables. These pipes are supposed to have chemical and corrosion resistance, high elasticity module and toughness, long term tensile strength and abrasion resistance, but they may become brittle exposed to cold atmosphere. In addition, they tend to deform and lose their strength in high temperature conditions. Insufficient strength and chemical resistance may cause failure. These pipes have gotten better properties by the use of nano particles.
