What are the "superiorities" of PVC drainage fittings relative to cast iron pipes?

When spring comes with her unique new green and sea, it can really make people fascinated; when spring carries her unique gentleness and tides, it can also make people break their souls. When the spring is full, the company ushered in the sales season of PVC drainage pipe fittings. Our company sincerely invites new and old customers to visit and purchase!

In the selection of drainage pipes for many projects, many choose PVC drainage pipes to eliminate the more common cast iron drain pipes in the 1980s and 1990s. What advantages does PVC drainage pipe fittings have over cast iron pipes?
1. Light pipe and convenient construction
For a long time, the drainage cast iron pipe has a large specific gravity, and it needs to be hemp, adjust the interface material, gargle and maintain during installation. The construction not only has heavy work, but also has a long installation time, which significantly reduces the construction efficiency. The PVC drainage pipe has a specific gravity of about 1.4t/m3, which is only l/5 of the cast iron pipe. The plastic pipe of the same length is much lighter than the cast iron pipe. It only needs to be manually handled during installation, and the PVC drain pipe fitting is The socket type viscous interface, at the same time, its standard length (6m, 4m) is longer than cast iron pipe, reducing the number of interfaces and reducing the installation process. For example, a standard 6m long DN110 plastic tube can be installed by one person, while a cast iron tube requires 2~3 people, so the installation time can be reduced by more than 60%, and the installation cost can be reduced by more than 50%. The construction unit can save costs, reduce costs, shorten the engineering cycle, and improve the economics of the building.
2, good drainage performance
According to the theoretical calculation of the gravity of the water film, when the flow area of ​​the drainage water film does not exceed 1/3~1/4 of the broken area of ​​the riser, the maximum water discharge capacity of the plastic riser is 60% higher than that of the cast iron pipe, and it does not cause The water seal is destroyed. Therefore, for the same equivalent displacement, the pipe diameter of the PVC drain pipe can be smaller than that of the cast iron pipe, or the same pipe diameter can be used as small as possible within the scope of the specification, thereby increasing the space. High, more beneficial to the user, enhances the use of the building.
3, economic and beautiful
According to the current market situation, the price of PVC drainage pipe fittings is only about 80% of that of cast iron drain pipes. That is to say, the construction cost per 1,000 square meters of construction cost per unit of construction cost is reduced by about 700 yuan compared with the cost of cast iron drain pipes. In addition, because PVC pipes are lighter, their transportation costs are also significantly reduced.
PVC drainage pipe fittings usually have white outer wall and are not used for anti-corrosion treatment such as red paint and silver powder. There is no such problem as rust corrosion of the outer wall of cast iron pipe. It does not require frequent maintenance and care when it is darkly inserted into the pipe well. The advantages of the tube are more significant: easy to clean, less obstructive to visual effects, greatly improving people's lives, working environment, and convenient property management of buildings.
4. Good social benefits
Today, China's steel supply is in short supply. PVC drainage pipe fittings can replace other steel drainage pipes in a wide range, and greatly reduce the energy consumption in the steelmaking process, and at the same time reduce the environmental pollution caused by this process. Has good social benefits.
5, superior physical and chemical properties
PVC pipe is a thermoplastic product, heated by PVC to a molten state (150 ~ 200 ° C), containing about 56% of the unique flame retardant element chlorine (Cl), so the oxygen index is high, is a flame retardant material, chemical stability, unique machinery The physical properties enable it to be used normally for up to 50 years. At the same time, its corrosion resistance, anti-aging and wear resistance make it more stable and durable than cast iron pipes and cement pipes, thus reducing the frequency of replacement repairs and reducing the frequency. The operating costs and the natural loss of materials contribute to the long-term use of the building and increase the safety and reliability of the building.
