Loose flange

The Loose flange (including the flange plate and flange head) of PVC-U pipe fittings is primarily used for connecting and sealing pipes. The PVC flange plate is a device used to connect parts and pipes, widely used in situations such as between shafts, at the inlets and outlets of equipment, and in pipe connections. Its main function is to connect two planes with bolts to form a seal and prevent liquid leakage. In the connection of PVC-U pipe fittings, the PVC flange plate plays a key role in ensuring a secure and sealed connection between pipes. The PVC flange head is typically installed on top of the flange and is mainly used to connect the flange and the pipe, ensuring the seal of the pipe. It plays an important role in the connection of containers such as pumps, valves, pressure vessels, and tanker trucks.

1. They can be applied in various situations, such as connections for pumps, valves, pipelines, and instruments under high temperature, high pressure, and corrosive conditions.
2. They are suitable for a wide range of applications, including water treatment, food processing, pharmaceutical production, chemical engineering, and many other industries.
3. Due to the certain elasticity of PVC Loose flange, they can reduce the vibration and noise generated when liquids or gases flow through the pipelines.
4. When pipelines or equipment need to be replaced or maintained, PVC unions can be easily and quickly disassembled.
