Gimbal Type Expansion Joint

Product Overview

GIMBAL TYPE EXPANSION JOINT

Dewdon’s Gimbal type expansion joints are designed to permit angular rotation in any plane by the use of two pairs of hinges affixed to a common floating gimbal ring. Simply, a double gimbal expansion joint is consisted of two single gimbal expansion joints and an intermediate pipe connects them each other.

This Dewdon model absorbs movement in all directions moving in a single plane and to a limited degree. For absorption of more extensive lateral movement, the optimal solution is to install our universal expansion joint.

  • Single Gimbal type

Double Gimbal type Expansion Joints

Our double gimbal expansion joint is basically a two single gimbal expansion joints and an intermediate pipe that joins them. This type of Expansion Joint can absorb a large lateral movement in any plane and angular movement in any direction.

Features

  • Limitation of bellows movements
  • Compression thrusts are restrained by the hard drive
  • Movement of bellows is more controlled.
  • Internal flow liners for eliminating velocity problems may be fitted.
  • Anchors only require to absorb spring forces.
  • Pressure thrust is restrained by the hardware.

Dewdon’s Gimbal metal Expansion Joints are manufactured in a way which allows them to handle angular movement in any plane by the use of two pairs of hinges affixed to a common floating gimbal ring. The gimbal ring, hinged and pins are designed to restrain the pressure thrust due to internal pressure and shear forces.

The gimbal ring is the key for the principe of the gimbal expansion joints – it can be either round or square. For round gimbals the torsional moment shall be considered and for square gimbals the instability due to the bending shall be considered

Features

  • Handles angular movement at any level
  • Slightest guiding required
  • Prevents contortions on the bellow elements
