Expansion Joint / Expansion Joint

Bellows: Twin (double) bellows configuration made of Stainless Steel SUS316 separated by a central pipe spool (Provides high flexibility and excellent resistance to corrosion and chemical attack).

Components Material: Available in Mild Steel, SUS304, or SUS316 depending on application requirements.

Ending Type: Tube End (Plain ends designed for direct butt-welding into the pipeline, ensuring a seamless, leak-proof joint).

Tie Rods: No (Unrestrained type; the piping system must be equipped with high-quality main anchors and guides to absorb internal pressure thrust).

Inner Sleeve (Liner): SUS304 or SUS316 (Protects the dual bellows from high-velocity media erosion and minimizes flow turbulence).

Axial Movement: Yes (Absorbs compression and elongation along the longitudinal pipeline axis).

Lateral Movement: Yes (The dual-bellows configuration allows for substantial parallel offset in all directions).

Angular Movement: Yes (Accommodates angular rotation and rotational deflections at the joint).

Multi-Directional Flexibility: By combining two bellows with a center pipe section, this unrestrained universal joint can absorb larger combinations of thermal expansion, lateral shear, and angular misalignment than single-bellows units.

Lightweight and Compact: The tube-end design eliminates the added weight, bulk, and potential leak paths associated with heavy matching flanges, facilitating a streamlined installation.

Low Pressure Drop: The inclusion of an inner sleeve ensures smooth fluid dynamics across both bellows sections, reducing turbulence and preventing product accumulation in the corrugations.
