Expansion Bellows / Expansion Joints

We offer ranges of standard as well as custom manufactured bellows to cater for many applications from heavy industry to food quality . The selection of bellows design, open:close ratios, stroke length, convolution width, split or endless configuration, and materials will depend on your specific application.


Where molded bellows are not suitable, a range of hand-built rubber bellows are available including tapered and smooth bore.


Our hand-built rubber bellows are designed to absorb motion and displacement between pipe flanges.


For more than 50 years, Shah India Rubber has stood at the forefront of fluid sealing technology. Our history of growth and success is rooted in our commitment to deliver the most innovative sealing solutions and unparalleled service to the world’s processing industries.


Rubber Expansion Joints protect equipments and piping from damage caused by vibration and thermal movements. While not their primary purpose, they are also frequently used to accommodate equipment misalignments. Rubber expansion joints provide superior flexibility, movement absorption, and cycle life, while resisting chemical attack and abrasion.


They are useful over a wide range of temperatures & pressures, making them the preferred expansion joint for most liquid and slurry applications, though gases & solids are also frequently conveyed by rubber expansion joints.


Function of rubber expansion joints :
  •  Damp oscillation, noise and vibration
  •  Compensate motion
  •  Compensate expansion caused by differences in temperature
  •   Reduce tension
  •  Compensate ground and foundation settling
  •  Compensate imprecise assembly
  •   Serve as assembly and disassembly aids
  •   Provide an elastic wall seal for penetration assemblies
  •   Compensate pipeline movements
Three features set Industrial Moulders Expansion Joint technology apart :

1.  It is entirely maintenance-free,
2.  Highly reliable in application and
3.  Extremely durable.
This means that operators can rely on our expansion joints for cost-effectiveness and sustainability.
