Product introduction:
PVC-U drainage pipe uses polyvinyl chloride resin as the main raw material, adds necessary additives, and is formed by extrusion processing. It is a series of drainage pipe products with mature technology and has been widely used at home and abroad. The product has the advantages of long life, corrosion resistance, etc., which is unmatched by cast iron pipes; it is lighter in construction, easy to handle and install, and easy to connect. It is widely used in civil construction drainage, chemical drainage, and rainwater drainage.

Features:
The product has the advantages of unmatched long life and corrosion resistance of cast iron pipes; it is lighter in construction, easy to handle and install, and easy to connect. It is widely used in civil construction drainage, chemical drainage, and rainwater drainage.
1. The surface hardness and tensile strength of the pipe are excellent, and the safety factor of the pipe is high.
2. Low cost, long service life, normal service life can reach more than 50 years, no need for regular maintenance and repair.
3. The pipeline has excellent corrosion resistance to inorganic acids, alkalis, and salts. It is suitable for industrial sewage discharge and transportation. It does not rust or scale, so there will be no corrosion and shrinkage inside.
It is not easy to be blocked, and the outer wall will not be polluted due to the rust of the pipeline, ensuring the beauty of the building.
4. The pipe friction coefficient is small, the water flow is smooth, not easy to be blocked, and the maintenance workload is small.
5. The material has high oxygen index and is self-extinguishing.
6. The linear expansion coefficient of the pipeline is small, and the amount of deformation affected by the temperature is small. The thermal conductivity and elastic modulus are small, and the anti-freezing performance is better than that of cast iron drain pipes.
7. The pipes and fittings are connected by glue, the construction method is simple, the operation is convenient, and the installation work efficiency is high.
8. It is non-toxic, does not contain toxic lead salts and other toxic chemicals, and is harmless to the human body.
