Clamp-Type Rubber Expansion Joint
■ Product Description
The Clamp-Type Rubber Expansion Joint is a flexible pipeline connector that uses stainless steel clamps to secure the rubber body onto the pipe. Compared to flanged joints, this design significantly reduces overall weight and simplifies installation by eliminating the need for flanges and bolts.
-
Universal Compensation: High flexibility allows for large axial, lateral, and angular compensation.
-
Zero Counter-Thrust: The structure ensures no reactive force is transmitted to the connected equipment.
-
Broad Compatibility: Suitable for connection with PE, PVC, cast iron, carbon steel, and galvanized pipes.
-
Full Customization: Available in any length, diameter, and wall thickness to meet specific engineering requirements.

■ Installation Notes
-
Preparation: Ensure the pipe outer diameter (OD) matches the internal diameter of the rubber joint.
-
Fixing: Slide the joint over the pipe ends and tighten the SS304 clamps to ensure a leak-proof seal.
-
Customization: For non-standard lengths or specific media (high temperature/acid), please specify during ordering.
