Gray PVC fittings is a kind of plastic pipe fittings, the main material is polyvinyl chloride (PVC). This kind of pipe fittings is gray in color and is usually used in water supply pipe systems, that is, pipes that supply our daily water.
Function
Gray PVC fittings are mainly used in water supply pipe systems. They have excellent properties such as acid resistance, alkali resistance, corrosion resistance, good pressure resistance, high strength, lightweight, low price, small fluid resistance, no secondary pollution, hygiene requirements, and convenient construction and operation. Gray PVC pipe fittings, as a mature water supply pipe, are widely used in various pipe systems that need to transport clean water to ensure the safety and purity of water quality.
Difference between gray PVC fittings and white PVC pipe fittings
The main difference between gray and white PVC pipe fittings is the purpose, pressure resistance, use environment, and price.
Purpose: Usually used as water supply pipes, while white PVC pipes are mostly used for drainage. This is because gray PVC pipes meet the standards for drinking water use and can meet the sanitary requirements of water supply, while white PVC pipes are generally used for drainage or sewage discharge due to the large amount of impurities.
Pressure resistance: The gray PVC water supply pipe has a higher pressure resistance, while the white PVC drainage pipe has a relatively lower pressure resistance. This is because the water supply pipe needs to withstand higher water pressure, while the drainage pipe mainly considers the ability to discharge sewage, and the pressure resistance requirement is relatively low.
Use environment: White PVC pipe fittings are not suitable for open-air environments because they are not resistant to direct sunlight, because when sunlight shines through the pipe to the liquid inside, it will produce chemical reactions, causing algae to grow on the inner wall of the pipe. Gray PVC pipe fittings are suitable for a wider range of use environments due to their better weather resistance and pollution resistance, including industrial production and sewage treatment.
Price: The cost of gray PVC water supply pipes is higher, while the price of white PVC drainage pipes is relatively low. This is because water supply pipes need to meet higher standards and requirements, and the production cost is relatively high, while drainage pipes have more impurities and relatively lower hygiene requirements, so the cost is lower.
Advantages
1. Hygiene and safety: Gray pvc fittings are opaque, which helps reduce bacterial growth and is more suitable for drinking water supply systems.
2. Durability: Gray pipe fittings are suitable for open-air environments and are not easy to age, while white pipes are prone to aging in the sun.
3. Applicable scenarios: In home decoration, gray pipes are often used in water supply systems, while white pipes are used in drainage systems. Water supply systems require higher hygiene standards and stronger pressure resistance.
