UPVC / CPVC pipe material instructions and knowlege
UPVC / CPVC pipe material instructions1. Material characteristics:
PVC is polymerized by vinyl chloride monomer (VCM). PVC material has the characteristics of non-toxic, anti-aging and acid and alkali resistance, so it is very suitable for use in chemical pipelines. The mixture of PVC raw materials with a certain amount of solid additives (no plasticizers) is called rigid polyvinyl chloride (UPVC).
CPVC is a polymer material modified by chlorination of polyvinyl chloride (PVC) again. After chlorination of PVC resin, the chlorine content is increased from 56.7% to 63-69%, which increases the chemical stability and improves the material. The heat resistance, acid, alkali, salt, oxidant and other corrosion; its thermal deformation temperature and mechanical properties are much higher than UPVC. Therefore, CPVC is one of the best engineering materials for industrial piping.
2. Introduction of pipeline system:
Both UPVC and CPVC piping systems have the characteristics of corrosion resistance, impact resistance, no deformation, smooth inner wall, no scaling, good thermal insulation, non-conductivity, easy bonding, and long service life. Therefore, it gradually replaces other metal piping systems on the advantages of high cost performance and low construction cost, and UPVC and CPVC piping systems are convenient and fast to maintain, and do not need to be shut down for a long time to cause huge losses. Therefore, UPVC and CPVC piping systems are currently designed for industrial piping First choice.
The maximum allowable operating temperature of UPVC piping system is 60 ℃, and the long-term operating temperature is 45 ℃. It is suitable for conveying some corrosive media with a temperature below 45 ° C; it can also be used for the conveyance of ordinary pressure fluids, generally used for water supply and drainage pipes, agricultural irrigation pipes, environmental engineering pipes, air conditioning pipes, etc.
The maximum allowable temperature of CPVC piping system is 110 ℃, and the long-term use temperature is 95 ℃. It is suitable for transporting hot water and corrosive media within the pressure range allowed by the standard. Generally used in petroleum, chemical industry, electronics, electric power, metallurgy, papermaking, food and beverage, medicine, electroplating and other industrial fields.
