Product Function

Connection sealing function: It can connect pipelines, valves, equipment, etc., and tighten them with bolts to form a seal at the connection part of the rubber flange, preventing fluid leakage and ensuring the sealing and integrity of the pipeline system.

Shock absorption and noise reduction function: Rubber has good elasticity, which can effectively absorb the vibration and noise generated by fluid flow in pipelines, reduce the damage of vibration to equipment and pipelines, and reduce the impact of noise on the environment.

Compensation displacement function: it can adapt to axial, radial, and angular displacements of pipelines caused by temperature changes, installation errors, and other factors, avoid stress concentration caused by pipeline displacement, and protect the safe operation of pipeline systems.

Corrosion resistance function: Rubber materials have certain corrosion resistance and can resist the erosion of certain chemical media, extending the service life of pipeline systems in harsh environments.

Buffer protection function: In pipeline systems, it can provide buffer protection for connected equipment and pipelines, reducing direct damage to equipment and pipelines caused by fluid impact, pressure fluctuations, etc.
