Drainage pipes

Properties

Pipe used for water mains and drainage are produced according to national standard NO. 1336 (DIN EN 1415) “Plastics piping systems for water supply and for buried and above-ground drainage and sewerage under pressure – Un plasticized poly(vinyl chloride) (PVC-U)” in diameter 12 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. 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

Main water pipes are used for water supply and sewage applications and drainage under burial in the soil and above the ground. They are made of  Polyvinyl chloride (PVC). 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.
