Mine the PVC tube

Brief introduction：
(1) with good tensile strength， compressive strength：but its flexi blt y is not as good as other plastic pipes.
(2) fluid resistance is small：PVC pipe wallis very smooth， the resistance to fluid is very small its roughness coefficient is only 0.009， its water delivery capacity is 20%higher than the same diameter of cast iron pipe， 40% higher than the concrete pipe.
(3) corrosion resistance， good drug resistance：PVC pipe has excellent acid resistance， alkali resistance， corro- sion resistance， not affected by moisture and soil pH， pipeline laying without any anti-corrosion treatment.
(4) with good water tightness：PVC pipe installation， whether the use of bonding or rubber ring connection， have good water tightness.
(5) rodent prevention：PVC pipe is not a source of nutrients， so it will not be eroded by rodents.
According to tests conducted by the National Health Foundation in Michigan， rats do not bite into PVC pipes (6) performance test：curing time， shrinkage， splitting strength， tensile property， peel strength， thermal st ablity， application period， storage period， release of harmful substances.

    Performance：

    (1) The installation is simple and the connection is convenient.After the flaring machine is flared， it can be easily connected.

    Sealing gasket can be used to ensure sealing.

    (2) wear resistance， corrosion resistance， smooth inner wall， small friction coefficient， corrosion resistance of a variety of chemical media， especially suitable for use in the coalmine underground humid air.

    (3) larger transmission flow， smooth pipe wall， can improve the flowrate of the medium， increase the flowrate， compared with the same metal pipe， can transport more medium， save power consumption.

    Application：underground coalmine gas drainage.
