OVERVIEW: Pipeline hydraulic surges are created by sudden changes in velocity of the liquid flowing in the system. This surging is often called hydraulic "water hammer" or "fluid hammer", and can result in pressures of many times normal operating pressure.
It can be caused by quick closing valves, pump start up or shut down, back surge, and other system effects. The edge welded stainless steel bellows that separates the surging fluid from the compressing nitrogen gas is the key.
The Hydropad surge absorber vessel / industrial water hammer arrestor has all stainless steel wetted parts with an edge welded metal bellows to ensure maintenance-free service and to allow for temperatures and liquids not practical with other units. The Hydropad provides the best fluid control performance possible.
