Detailed Description of UPVC Pipes for Underground Drainage & Sewerage:

The inner wall of the PVC-U drain pipe is smooth. Compared with pipes made of other materials, the water flow resistance is significantly reduced. Under the same pipe diameter and flow rate conditions, the water flow velocity in the PVC-U drain pipe is faster, which can effectively reduce the residence time of sewage in the pipe and lower the possibility of impurities in the sewage precipitating and blocking the pipe.
Common connection methods include socket and spigot adhesive bonding, socket and spigot connection with rubber ring sealing, and flange connection, etc. The socket and spigot adhesive bonding has a tight connection and good sealing performance; the socket and spigot connection with rubber ring sealing is convenient for installation and can adapt to a certain degree of pipe deformation; the flange connection is suitable for the parts that need to be frequently disassembled or have high requirements for sealing performance.

Characteristics and Advantages of Polyvinyl Chloride (PVC-U) Drain Pipes

Strong Corrosion Resistance: It can resist the erosion of various chemical substances, including acids, alkalis, salts, etc. It can remain stable in different water quality and soil environments, is not easily corroded, and prolongs the service life of the pipeline.
Less Likely to Scale: The inner wall is smooth, with low water flow resistance, and it is not easy to scale. It can effectively prevent pipeline blockage, ensure smooth drainage, and reduce the workload of pipeline maintenance and cleaning.
Good Water tightness: By using methods such as rubber ring sealing or adhesive connection, it can ensure that the pipeline joints have good water tightness, effectively prevent sewage leakage, and avoid pollution to the surrounding environment.
Good Impact Resistance: It has a certain degree of toughness and impact resistance strength. When subjected to external impact or ground settlement, etc., it is not easy to break and can ensure the normal operation of the drainage system.
Excellent Aging Resistance: It can withstand the influence of factors such as ultraviolet rays, oxygen, and moisture, and is not easy to age or embrittle even when used outdoors for a long time, with stable performance.
Lightweight: With a relatively low density and light weight, it is convenient for handling and installation, reducing the construction difficulty and labor intensity. At the same time, it is also beneficial to reducing the structural load in high-rise buildings.
Good Sound Insulation Effect: It has a certain blocking effect on the noise generated by the water flow, can effectively reduce the noise during drainage, and provide a quieter living and working environment.
Environmentally Friendly and Hygienic: The material itself is non-toxic and will not cause harm to the environment and human health, meeting the relevant national environmental protection standards.
Economical and Practical: The price is relatively low, and the installation cost and maintenance cost are not high either. It has a high cost-performance ratio and can save costs for engineering construction.
