Rigid polyvinyl chloride pipes for pressureless underground sewage and drainage are light and easy to connect. Compared with other pipes, installation is very simple. Rigid polyvinyl chloride pipes for pressure-free underground sewage and drainage have outstanding advantages and a wide range of uses. After considering The material's chemical resistance and heat resistance make it suitable for a wide range of applications.

Product Structure

Rigid polyvinyl chloride (PVC-U) pipes for pressureless underground sewage and drainage use polyvinyl chloride (PVC) resin as the main raw material, add appropriate amounts of additives, etc.,and are extruded and molded by a plastic extruder, and then cooled and solidified , shaping, inspection, packaging and other processes to complete the production of pipes.

Performance Characteristics

High safety factor

The surface hardness of the pipe is high, and the pipeline safety factor is high.

50+Long life time

It has good aging resistance and its normal service life can reach more than 50 years.

preservative

The pipeline has excellent corrosion resistance to inorganic acids, alkalis and salts.

Small friction coefficient

The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to be blocked, and the maintenance workload is small.

Self-instruction

The material has a high oxygen index and is self-extinguishing.

Easy to construct

Pipes and pipe fittings can be connected by bonding. The construction method is simple, the operation is convenient, and the installation efficiency is high.

water tightness

Good water-tightness: The installation of PVC-U pipes, regardless of whether they are connected by bonding or rubber rings, has good water-tightness.
