Metal Bellows 

Metallic Bellows for Extreme Flexibility​

Bengal manufactures precision-engineered metallic bellows designed to perform reliably in the most demanding operating environments. Our thin-walled bellows are engineered to accommodate axial, lateral, and angular movements while maintaining excellent resistance to internal pressure, cyclic loading, extreme temperatures, corrosion, and torsional stresses.

Engineering & Design Capabilities​

Inspection & Testing​

Every metallic bellow is manufactured under stringent quality controls and can be tested using:

Manufacturing Capabilities​

Material Grades​

Stainless Steels: SS304/304L, SS316/316L, SS316Ti and SS321
Nickel Alloys & Special Materials: Inconel® 600, 601 & 625, Incoloy® 800, 800H & 825, Monel® 400, Hastelloy® C-276, Copper, and other special alloys on request.

Bellows Configurations​

Single Ply – Ideal for low-pressure applications with limited thermal movement and vibration.

Double Ply – Provides an excellent balance of flexibility, fatigue life, and pressure capability.

Multi-Ply – Constructed from multiple concentric thin-wall plies to achieve superior flexibility, longer cycle life, enhanced pressure resistance, and improved reliability in high pressure critical applications.
