1The material has high oxygen index and self extinguishing property.
2The 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 excellent compared with the cast iron drainage pipe.
3The pipes and pipe fittings can be connected by bonding. The construction method is simple, the operation is convenient, and the installation efficiency is high.
4Good water tightness: the installation of pvc-U pipe has good water tightness, whether by bonding or rubber ring connection.
