SUS304 Double Gimbal Expansion Joint ISO 9001 Certification Flange Connection

SUS304 Double Gimbal Expansion Joints ISO 9001 certification Flange Connection

Product description

Double Gimbal: Designed to absorb lateral and angular movements in any direction. This model is made up of two bellows joined together by a linking pipe and a double cardan system.

A 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.

Pressure Balanced: A pressure balanced expansion joint accommodates axial and lateral movements and counteracts the bellows pressure thrust. An additional bellows is incorporated into the unit and is subject to the line pressure to generate a force equal and opposite to that on the main bellows. Tying these bellows together neutralises the pressure load on the unit.

This particular type of Expansion Joint offers the additional advantage of not transferring the thrust caused by the internal pressure to the pipes or adjacent equipment. This characteristic is especially important when it comes to joining the pipes to turbines or other delicate equipment which, by their nature, are unable to withstand these extra loads.

Performance characteristics

The synthetic displacement of multi-plane curved pipe segment is compensated mainly by angular deflection.Since the balance ring, pin shaft and hinge plate can bear the pressure thrust and other additional external forces, the expansion joint itself absorbs the internal pressure thrust and will not produce external forces on the pipeline, so the setting of pipeline support can be simplified.The universal hinge ripple compensator can compensate the arbitrary upward angular displacement of the pipeline.The universal hinge type expansion joint is different from the hinge type in that it has a universal ring and two pairs of hinge structures perpendicular to each other in the circumferential direction of the universal ring, so it can absorb the angular displacement of any plane, and two or three combinations are needed to absorb the displacement.
