Advantages

● The surface hardness and tensile strength of PVC drainage pipes are excellent, and the pipe safety coefficient is very high.

● PVC drainage pipe of good aging resistance, usually its normal service life can reach more than 50 years.

● PVC drainage pipe has a very good corrosion resistance to inorganic acid, alkali, salt and other substances, so it is more suitable for industrial sewage discharge and transportation.

● PVC drainage pipe friction coefficient is small, smooth flow, not easy to plug, less maintenance work, and high oxygen index, with self-extinguishing.

● PVC pipes, small linear expansion coefficient, is 0.07 mm / ℃, affected by the temperature of the deformation is small. 

● Small thermal conductivity and modulus of elasticity, excellent freezing resistance.

● PVC drainage pipe connection can be adhesive method, simple construction, easy operation, high installation efficiency.
