The surface hardness and tensile strength of pvc drainage pipes are excellent, and the pipeline safety factor is extremely high.The linear expansion coefficient of pvc drainage pipe is small, 0. 07mm/℃, small deformation due to temperature. Small thermal conductivity and elastic modulus, excellent frost resistance.PVC rainwater pipes have excellent toughness, and the surface hardness and tensile strength of pipe fittings are excellent. PVC drainage pipe can be connected by bonding method, which is simple in construction, convenient in operation and installation.PVC drainage pipe has good aging resistance, and its normal service life can reach more than 50 years.Pvc drainage pipe has excellent corrosion resistance to inorganic acid, alkali, salt and other substances, so it is more suitable for industrial sewage discharge and transmission.It has good weather resistance and can not be corrupted by bacteria and fungi.The inner wall is smooth, the fluid fluidity loss is small, the dirt is not easy to attach to the smooth pipe wall, the maintenance is relatively simple, and the cost is low.
