PVC pipe drainage fittings

PVC drainage pipes are mainly made of sanitary grade polyvinyl chloride (PVC) resin, with appropriate stabilizers, lubricants, fillers, color enhancers, etc. added. They are extruded by plastic extruders and injection molded by injection molding machines. Through cooling, curing, shaping, inspection, packaging and other processes, the production of pipes and fittings is completed.

The common specifications of PVC drainage pipes are as follows: nominal outer diameters are 32 mm，40mm，50mm，75mm，90mm，110mm，125mm，160mm，180mm，200mm，250mm，315mm，400mm，500mm，630mm The length of PVC-U pipes is generally 4m or 6m, and other lengths are determined through negotiation between the supply and demand parties.

Product advantages:

1. The surface hardness and tensile strength of the pipe are excellent, and the safety factor of the pipeline is high.

2. It has good aging resistance and a normal service life of more than 50 years.

3. The pipeline has excellent corrosion resistance to inorganic acids, alkalis, and salts, and is suitable for industrial wastewater discharge and transportation.

4. The pipeline has a low friction coefficient, smooth water flow, is not easily blocked, and requires less maintenance work.

5. The material has a high oxygen index and self extinguishing properties.

6. The coefficient of expansion of the pipeline is small, at 0.07mm/℃, and the deformation is less affected by temperature. The thermal conductivity and elastic modulus are small, and compared with cast iron drainage pipes, the anti freezing performance is excellent.

7. The connection of pipes and fittings can be made by bonding, with a simple construction method, easy operation, and high installation efficiency.

8. Good water tightness: The installation of PVC-U pipes, whether connected by adhesive or rubber rings, has good water tightness.
