What kind of pvc pipe to use for stormwater drainage?
A stormwater drainage pipe is a pipe system that mainly uses pipes to discharge rainwater (including snowmelt water) to natural water bodies or to sewage treatment plants for treatment. This system generally only performs primary sedimentation treatment, and sometimes can also be used to discharge relatively clean industrial wastewater. The main purpose of rainwater drainage pipes is to effectively collect and discharge rainwater from roofs, ground, or other places to prevent flooding while protecting the environment and public safety. At present, PVC pipe is often used in rainwater discharge. This paper mainly introduces the advantages of PVC pipes in rainwater discharge.
How do you choose PVC pipes for rainwater discharge?
1. Material and quality: Make sure that PVC pipes are made of high-purity polyvinyl chloride resin with good corrosion resistance and aging resistance. Check whether PVC pipes meet national or international standards, which specify the physical and chemical properties of PVC pipes.
2. Size and specification: Select the appropriate pipe diameter according to the actual drainage needs. Commonly used drainage pipe diameters are Φ50mm (2 inches), Φ75mm (3 inches) and Φ110mm (4.25 inches). Φ110mm drain pipes are often used in the main drain pipes of kitchens and bathrooms to ensure smooth drainage.
3. Wall thickness and strength: Choose products with wall thickness that meet the regulations. Generally speaking, the thicker the wall thickness, the longer its pressure resistance and service life.
4. Brand and reputation: Choose well-known brands such as Puhui, which has more than 20 years of experience in pipeline production and R&D, has a good reputation and reputation in the market, and the product quality is guaranteed.
5. Connection method : Consider the connection method of PVC pipe, such as adhesive connection, rubber ring connection and threaded connection. The selection of the appropriate connection method should consider the ease of installation, tightness and reliability .
6. Environmental adaptability: Consider the environmental conditions where the PVC pipe will be installed, such as temperature changes, UV exposure and chemical contact. High-quality PVC pipes should have good weather resistance and chemical corrosion resistance.
Advantages of PVC pipes for rainwater drainage
1. Excellent corrosion resistance: PVC drainage pipes have excellent acid resistance, alkali resistance, and corrosion resistance, which are very suitable for chemical industry use. They can effectively resist the chemicals that may be contained in rainwater and protect the pipes from corrosion.
2. Low fluid resistance: The inner wall of the PVC drainage pipe is smooth, the roughness coefficient is low, and the fluid resistance is small. It can effectively improve the hydraulic conditions of the pipe network, reduce the system operation cost, and ensure that rainwater can be discharged quickly.
3. Lightweight and easy to install: The density of PVC drainage pipes is small, and it is convenient to carry, load unload, and construct, which reduces the difficulty and cost of construction.
4. Long service life and low cost: PVC drainage pipes are low in price, easy to transport and construct, and have a long service life. Therefore, the overall cost is low and suitable for large-scale use.
