Chlorinated polyvinyl chloride (CPVC) is a unique polymer after polyvinyl chloride chlorination. Ordinary PVC molecular chlorine content is 45%, while CPVC molecules chlorine content is about 64% to 68%, up to more than 70%. CPVC tensile capacity is higher than the UPVC, PP, PP - B, PP - R H, PB, HDPE, PE, PE – X RT, etc.; its thermal expansion coefficient is lower than the PP, PE, PB; thermal conductivity is lower than that of PP, PE, PB and metal pipe; the temperature resistance and resistance to deformation ability is better that that of PP, UPVC, ABS and HDPE.
CPVC pipes are designed in copper tube size from 1/2” to 2”, with two kinds of standards in dimensional ratios, SDR-11 and SDR-13.5. The fittings are designed with standard SDR-11. SDR13.5 pipe match the standard ASTM F442. The specification of those products, which covers requirements, test methods and methods of marking of components made in one standard dimension ratio and intended for water service, can match the standard ASTM D2856.
FEATURES OF PRODUCT
- Safety and Health – the extremely low rate of harmful bacteria breeding is superior to drinking water hygiene standard designed by both the World Health Organization and the People’s Republic of China Ministry of Health. Thereby, it was recommended for medical system.
- Flame Retardant – limited oxygen index of CPVC material is 60%. The minimum ignition temperature is 482°C. No dropping fire, very low smoke rate and no poisonous gas.
- Corrosion Resistant – CPVC material has strong resistance to acid and alkali, which can be used for delivering liquid of HCL and NaOH.
- Low Thermal Expansion Coefficient – CPVC material has low coefficient of thermal expansion. Expansion loop length is 16 feet, under the condition of 100F temperature change and 20’ holding.
- Anti-Ultraviolet – the ultraviolet rays will not cause breakage of polymer chains structure.
- Long Service Life – CPVC material has strong antioxidant and aging resistance performance than other material in utilization.
FIELDS OF APPLICATION
- Hot and cold water applications in home, apartments, hotels, resorts, hospitals, high and low rising buildings, corporate commercial houses, academic institutes, etc.
- Piping networks for pure water and medicament in pharmaceutical factory.
- Piping networks for beverage, dairy and drinking water supply.
