EN545 Large Range Flexible Bolt Joint Carbon Steel PN10/16 PVC Pipe Universal Coupling
The material and performance of the product
Wide-range flexible compensation joints are usually made of high-performance materials such as stainless steel and EPDM rubber, which have good corrosion resistance, compressive resistance and flexible angle adjustment ability. These characteristics enable the flexible joints to maintain stable performance in high temperature or humid environments, ensuring long-term stable operation of the system.
Product Applications
1. Petrochemical industry: In the transmission pipeline system in the fields of petroleum, natural gas, chemical industry, etc., the flexible joint can withstand the harsh working environment such as high pressure, high temperature, corrosion, etc., to ensure the safe operation of the pipeline system.
2. Electric power industry: In the power transmission pipeline system, flexible joints can ensure the stability and safety of power transmission.
3. Metallurgical industry: In the conveying pipeline system in metallurgical production, flexible joints can ensure the smooth progress of the production process.
4. Shipbuilding industry: In the ship's piping system, the flexible joint can withstand the harsh working environment such as seawater corrosion and hull vibration to ensure the normal operation of the ship.
5. Aerospace industry: In the piping system of aerospace vehicles, flexible joints can ensure the normal operation of aerospace vehicles.
