The linear expansion coefficient of the pipeline is small, 0.07mm/℃, and the deformation affected by temperature is small. The thermal conductivity and elastic modulus are small, and the frost resistance is better than that of cast iron drain pipes. The pipes and pipe fittings can be connected by bonding. The construction method is simple, the operation is convenient, and the installation efficiency is high.
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.
Good drainage performance. PVC drainage pipe has good drainage performance, because the PVC drainage pipe has a small diameter and a small slope, which can increase the clear height of the space, which is more beneficial to users and enhances the use function of the building.Superior physical and chemical properties. The physical and chemical temperature of PVC drainage pipe has the advantages of strong corrosion resistance, aging resistance, wear resistance and long service life.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.
