CPVC SCH 80

CPVC SCH 80

    High heat resistance 

    High resistance to chemical 

    High mechanical strength

    Small fluid resistance 

    Weather resistance 

    Low dissolution rate 

    East construction and cost-saving 

Back

In addition to holding the same features as PVC SCH80, the chlorination degree of CPVC resin is higher. Additional chlorine can increase temperature resistance up to 100 degree Celsius. CPVC SCH 80 offers high density, abrasive resistance, lower combustion, and lower smoke. Besides, it can also limit flame diffusion and possess better higher temperature resistance.

Remark
1. Also available in offering PVC SCH40/CPVC SCH40 piping and fittings, please feel free to contact us.
2. The pressure resistance of Solvent Cemented Joint fittings and Spears SR (Stainless Steel Reinforced) fittings is approx. 60% of the pipe; the pressure resistance of standard thread fittings is 50% of the pipe.


Warning
1. PVC SCH80/CPVC SCH80 is not allowed in transferring the compressure air or gas.
2. Do not use compressed air or gas in testing any PVC or CPVC thermal plastics piping system; Do not apply the equipment that activated by air or gas to clean-up the system. The above actions will probably cause the burst of the piping system and even cause serious harm to humankind.
