In municipal drainage, sewage treatment and underground pipe systems, PVC SDR 35 pipe fittings have become the first choice of engineers and construction workers due to their superior performance and wide applicability. Its light weight, corrosion resistance and high strength make it occupy an important position in modern drainage systems.
What are PVC SDR 35 pipe fittings?
SDR (Standard Dimension Ratio) refers to the standard dimension ratio of the pipe, that is, the ratio of the outer diameter to the wall thickness. SDR 35 means that the ratio of the outer diameter to the wall thickness of the pipe is 35, which is usually used in low-pressure drainage systems such as municipal sewage pipes, rainwater drainage and underground drainage projects. PVC SDR 35 pipe fittings are specially designed for these pipes to ensure tight connections, smooth fluid flow, and long-term resistance to external pressure and environmental erosion.
Advantages of PVC SDR 35 pipe fittings
1. Strong corrosion resistance
PVC material has excellent chemical corrosion resistance and is not affected by sewage, acidic liquids or industrial wastewater, ensuring long-term stable operation of the pipeline system.
2. Lightweight and easy to install
PVC SDR 35 pipe fittings are lighter than metal pipe fittings, making installation more convenient and reducing construction costs and labor costs.
3. High strength and pressure resistance
The SDR 35 standard design enables the pipe fittings to have excellent pressure resistance, withstand underground soil pressure, and be suitable for different geological environments.
4. Excellent water flow performance
PVC SDR 35 pipe fittings have a smooth interior, reducing fluid resistance, reducing the risk of sediment accumulation, and improving drainage efficiency.
5. Strong sealing and anti-leakage
Adopt advanced rubber ring sealing or adhesive connection methods to ensure that the system is leak-free and effectively protect groundwater resources.
