Elaflex ERV Rubber Expansion Joints

Flexiducting Ltd are suppliers of Elaflex Rubber Expansion Joints. These rubber bellows are manufactured in Germany and are recognised as the leading brand.

Rubber Expansion Bellows (Compensators) are used as flexible connectors within pipe systems. Based on the German expression “Elastische Rohrverbinder“ the type brand ERV® is being used.

ERV expansion joints from ELAFLEX HIBY are moulded single sphere type rubber bellows with swiveling metal flanges. Their construction and lengths have since become internationally recognised standard.

V-Loop & U-Loop Seismic Joints

Flexiducting are suppliers of seismic joints and expansion loops designed for pipeline systems to absorb movement during seismic activity and thermal expansion/contraction.

During an earthquake it protects critical pipelines transfering hot and cold water, gases, fuel and sewerage, and also offers protection for vital equipment by allowing boilers, chillers, fan-coil units and other systems to move independently from buildings such as hospitals, high rises, stadiums and civil defence centres.

We can offer custom designed and manufactured V-Loop or U-Loop assemblies to allow for movement on all axis up to 500mm.

Sizes up to 500mmNB.
