The thermal movement requirement can be axial, lateral or angular .

SBM Bellows follow latest EJMA Standard and ASME for design, manufacture and quality assurance of Metallic Bellows & Joints. We manufacture bellows from I.D 25MM to I.D 2500MM. SBM Expansion Joints are made of material obtainable in sheet form & have reasonably good ductility and weldability. Cold Rolled Austentic Stainless Steel 304, 316, 321, 316L, Inconel is used in general in thin and medium walled or multiply bellows or customers requirements. We offer all types of end fittings and in all grades of materials as per customers requirements and application.

What Are Expansion Joint Bellows? An expansion joint is a structural assembly designed to manage stress and dimensional changes in building materials caused by:

• Thermal expansion and contraction
• Movement due to wind
• Movement due to seismic waves.

The structure is applicable between building sections, in bridges, railway lines, sidewalks, ships, and most importantly, piping systems. It acts as a heat and vibration absorber and prevents the building parts from falling out. It can also help in fireproofing, waterproofing, and soundproofing building elements. Expansion joints made of metal are known as bellows.

What Are The Common Types Of Expansion Joints?

• Hinged Expansion Joints

These Expansion Joints can absorb lateral deflections in a single plane undergoing thermal contraction and expansion. It prevents the axial deflection of the material with the help of pivots. The product is designed to withstand pressure thrust.

• Axial Expansion Joints

Axial Expansion Joints can absorb longitudinal deflections in a straight line. It is one of the best know simple means of stress compensation. It allows movements in all directions without redirecting pipe work or altering the direction of flow.

• Universal Expansion Joints

This Expansion Joint comprises of two bellows separated by spool in the centre. It is designed to absorb lateral expansions in large amounts. The length of the central spool determines the capacity of the expansion joint to sustain such deflections.

• Metallic Expansion Joints

Also known as compensators, these expansion joints comprise of metal bellows and can absorb three types of deflections – lateral, axial, and angular. Their use is best pronounced in pipe work and relevant machinery work.

What Are The Advantages of Expansion Joints Manufacturers in India?

• Simple design, easy to install, and cost effective
• Prevention of displacement of building elements due to seismic movements
• Prevention of cracking of pipe due to thermal contraction and expansion.
• Allowance of flexible movement even at low installation height.
• Minimal reactive and adjusting forces.

What Are The Industrial Applications of Expansion Joints Bellows? Expansion joints are applicable to various industrial applications including the following:

• Power Generation Units
• Chemical Processing Plants
• Pressure Vessel Manufacturing

Hinged Expansion Joint are designed and are used to restrict axial deflection either in extension or compression. Hinged Joints contains hinged or pivots which allow the unit to bend in a single plane. The Hinge mechanism is typically designed to accept full pressure thrust. Hinged Joints can either be Axial or Universal type.
