EPDM Rubber Wide Arch Bellows Type Expansion Joint Manufacturer

EPDM Rubber Wide Arch Bellows Type Expansion Joint Manufacturer


Product Description

Bellows type expansion joint design forms an integrated seal by extending the rubber edge and wrapping it around the metal flange. Compared with traditional flat expansion joints, the flap structure effectively reduces the risk of media leakage and enhances the protection of the flange surface, avoiding seal failure due to flange corrosion or mechanical damage. In addition, the flanging part can absorb part of the axial displacement, reduce the stress concentration of the rubber body, and prolong the service life.


Performance characteristics

1.High flexibility

Make the size, shape, and thickness of the reinforcement layer of the joint according to the needs

2.Diversified reinforcement materials

Hand wound rubber joints can use a variety of reinforcement materials to provide the required mechanical strength and corrosion resistance.

3.High pressure bearing capacity

Manual winding can ensure the structural uniformity of the joint, thereby improving its pressure bearing capacity and overall strength.

4.Easy maintenance and replacement

Usually equipped with flanges or threaded interfaces for easy installation and replacement, reducing downtime of pipeline systems.
