Rubber expansion joints / compensators are used as flexible connectors within pipe systems. Based on the German expression "Elastische Rohrverbinder" the type brand ERV® is being used.
ERV are single sphere type rubber expansion joints within swiveling metal flanges. The high quality bellows are produced in a mould. Starting fourty years ago, construction and length of ERV expansion joints have become reckognised standards worldwide. Problem Solvers within Pipe Systems
ERV are distinguished by a large axial, lateral and angular range of allowable movement, low reaction forces and low inherent resistance.
ERV are used to absorb tensions caused by temperature changes (thermal expansion), and equalize structural settling such as basement subsiding or ground movements.
They are suitable as a pipe insert / expansion piece to
facilitate inspections of valves or other devices.
ERV are perfect noise dampeners and ideally qualified to reduce vibrations. The major part of the piping's structure-borne noise and the low-frequency noise generated by fluids is eliminated.
"Better safe than sorry": ERV serve to equalise assembly inaccuracies. If ERV are provided for during the planning phase there will be less problems during installation caused by inaccuracy. This saves costs.
Quality production: only premium quality bellows exclusively made for us by ContiTech, Germany are used. Both ELAFLEX and ContiTech have a reputaion for reliability and longevity.
Big range: for practically all media, sizes DN 25 - 1000 mm.
