Abstract
The present invention relates to a surge absorber that may be easily custom fabricated to a particular flow line application. The surge absorber prevents "water hammer" by providing an enlarged compressible fluid chamber that is separated from the flow line by a diaphragm. When the pressure surge occurs, the greater incompressible fluid volume provided by the intermediate tubular section of the pressure vessel housing provides sufficient baffling while an internal diaphragm protector protects the diaphragm from damage by the incompressible fluid.
