Twin Hinged Expansion Joints

Sizes available: 80mm-3metre N.B.
Pressure Ranges:
upto 40kg/cm2
(large sizes can be supplied)
Two hinged joints are together by a center tube, allowing large lateral movements at high pressure & can be fitted with pipe ends or flanges. Limit stops control the degree of movements.

Pressure Balanced Expansion Joints

Sizes, types & pressure ranges to suit specific applications.
Pressure Balanced Bellows are used in piping systems where pressure loads are critical & where complex axial & lateral movements are involved when space is limited. Using a pressurised bellows outside the system to counteract forces generated by bellows inside the system, large axial and lateral movements can be absorbed.
