Hinged Expansion Joints manufacturers in India

Hinged Expansion Joints suppliers pliant bellows

Hinged expansion joints are the type of expansion joints that are restricted to rotate in a single plane. The hinged expansion joints are used to absorb the changes that are a result of piping thermal expansion or a contraction.

First of all, it is important to restrain the pressure thrust. Hinges are added to the edges of the expansion joints with the use of pairs of pins. This allows a crossing movement in a single plane, hence, restraining the pressure thrust, also preventing the expansion joint from diverting axially during compression and decompression as well. Therefore, the hinged expansion joints provide for angular movement and maintain pressure thrust forces They can be used without pairing but for better outcomes, it is suggested that they are used in sets of two or three.

Hinged expansion joints are flexible bellows used in piping systems. When used in isolation, these hinged expansion joints are restricted to the pure angular rotation because of its flexible joint hinges. When used in pairs or sets, the expansion joints will operate together consuming parallel deflection. Hinged expansion joints prove to be advantageous as they are typically compact in size and are structurally rigid.

ADVANTAGES OF USING HINGED EXPANSION JOINTS:

  • All pressure thrust is held by the hinge pins and is not imposed on pipes work, anchors or equipment.
  • Forces that deflect the bellows are minimal.
  • The hinged expansion joints are also typically compact in size and are structurally rigid.
  • Guides are not found necessary on short pipe runs like in boiler house systems. For long pipe runs, only the simple type of pipe guides are applied.
  • A single pair of hinged expansion joints has the ability to absorb enormous amounts of decompressions or expansions, hence, providing to considerable savings in the guides, anchors, and actual joint cost.

Applications:

  • Industrial piping systems
  • In aerospace components
