Expansion joints are crucial components used in a range of engineering and construction installations to accommodate movement, primarily thermal expansion, contraction and movement, in various structural and mechanical systems. Hydraflex, a notable UK-based manufacturer, offers a variety of expansion joints including Metal Hose and Bellows, suited for diverse applications in the UK and overseas markets​.

Construction and Compliance

Hydraflex’s expansion joints are meticulously designed to cater to different movement needs. For instance, their threaded type axial expansion joints are engineered to absorb thermal expansion and vibrations in connected pipelines, with integrated liners to minimize contact between the inner surface of the bellows and the fluid, ensuring smooth flow and reduced friction losses. The stainless steel bellows (membranes) are an integral part of the construction​. Moreover, their Flexible Pump Connectors are compliant with ISO 10380:2012, highlighting adherence to quality and industry standards​.


These products find applications across a range of sectors including heating and ventilation, building services among others​. The axial expansion joints are particularly useful in managing thermal expansion and vibrations in pipelines, while the flexible pump connectors are used to absorb lateral movement in pipelines and reduce vibrations from pumps​.

Benefits and Features

Hydraflex expansion joints offer a plethora of benefits like absorption of thermal expansion, vibration damping, and facilitation of angular rotation in structural setups. Special features include the use of stainless steel bellows and integrated liners to ensure smooth fluid flow and reduced friction losses. Additionally, the design of certain expansion joints like the HN.FS type and GB.FS type, permit angular rotation in one or multiple planes, making them highly versatile for different operational needs.
