Pulsation dampeners can be used for the following cases:It can be used for leakages in a hydraulic system. Also it can be used for any pressure changes due to thermal expansion.
It can be used as an energy storage device (Accumulator) in a hydraulic system. It supplies hydraulic power for a short period of time. This property is crucial for lube oil system which has to supply lube oil to critical rotating equipment wherein slightest delay may result in a costly failure to the equipment.
Pulsation Dampeners installed close to the valves is used to absorb the surge which is risen from the sudden pump shut-downs when the fluid flows back slamming into the pump or check valve.
It can be used in absorbing the surges like water hammer results from the sudden change of kinetic energy...

Wellhead Equipment
Wellhead equipment are used in connecting the casing and tubing to an oil or gas pipeline. These are useful in suspending the casing strings and help seal the well. The casing is a permanently-installed pipe for lining the well hole to provide pressure containment and prevent collapse. The wellhead equipments are known as the flanged devices that are attached to the casing.Wellhead equipments include a number of other components such as casing heads, casing spools, tubing head spools, tees, and crosses. The casing head is part of the connection between the casing and the wellhead equipment itself. Usually, many...
