Advantages of in building drainage engineering and water supply engineering applications

1. Advantages of UPVC pipe in the application of building drainage engineering
(1) Hard material without plasticizer, excellent surface hardness and tensile strength of the pipe, high pressure resistance grade and pipeline safety factor,
(2) Good anti-aging performance, normal service life can reach more than 50 years.
(3) The weight is light, 1/5 of the cast iron pipe, the installation is convenient, and the project cost is significantly reduced.
(4) Excellent corrosion resistance to various inorganic acids, alkalis and salts, suitable for all kinds of industrial sewage discharge and transportation.
(5) The friction coefficient is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small.
(6) The material has a high oxygen index, is a Class B flame-resistant material, and has self-extinguishing properties.
(7) The expansion coefficient of the pipeline is small, which is 0.07mm/(m'°C), the deformation is small under the influence of temperature, 100%~130% lower than that of similar polyolefin materials, and the thermal conductivity and elastic modulus are small. Compared to cast iron drain pipes, it has excellent resistance to freezing.
(8) Pipes and fittings can be connected by bonding, the construction method is simple, the operation is convenient, and the installation efficiency is high.
2. Advantages and disadvantages of UPVC pipes in the application of building water supply engineering
The advantages of UPVC water supply pipes are (1) corrosion resistance, aging resistance, long service life, and service life of more than 50 years;

(2) Strong impact resistance, high mechanical strength, can withstand high internal pressure and high tensile strength;

(3) No blockage, no scaling, smooth inner wall, low fluid resistance, small head loss;

(4) Tasteless, non-toxic, no rusty water, avoid secondary pollution of water sources, and the water quality is hygienic and reliable;

(5) Light weight, convenient handling, loading and unloading, flexible and convenient installation, significantly reduce the project cost;

(6) Good sealing performance;

(7) Use a unique auxiliary agent to make the product not emit the smell that pests like, and avoid termites and rats from biting and destroying.
In short, the use of UPVC pipes in building water supply and drainage projects can not only facilitate construction, reduce project costs, but also help ensure water quality, save operating costs, and reduce production costs.
