What should be noted during the installation of flanged rubber expansion joints?

2025-11-03

When installing flanged Rubber Expansion Joints, the following key points must be noted:

Strictly prohibit installation beyond displacement limits: During the installation process, it is not allowed to exceed the displacement limit of the joint; otherwise, it may lead to pull-off or leakage.

Symmetrically install bolts and gradually tighten them under pressure: This is to prevent local leakage. When the pressure exceeds 1.6 MPa, the bolts should be equipped with elastic pressure pads.

When installed vertically, anti-pull-off devices and supports must be added: This is to prevent the joint from being pulled off under pressure and ensure safe operation.

The installation site should be kept away from heat sources, ozone-rich areas, and strong radiation: This is to avoid environmental factors causing damage to the joint.

During transportation and handling, it is strictly prohibited to scratch the surface and sealing face with sharp tools: This is to prevent physical damage that could affect the sealing performance. Ensure that the pipeline ends are clean and free of foreign matter, and that the flanges are well-aligned: This guarantees good sealing and a stable connection.

Regularly inspect the tightness and sealing performance of the joint: This allows for timely identification and resolution of issues, ensuring long-term stable operation. These precautions help to ensure the installation quality and operational safety of flanged Rubber Soft Joint.
