PipeHugger Low Pressure Pulsation Dampeners with Elastomer Bladder
The principle of operation & features of the "PipeHugger" liquid bladder are: a large diameter chamber, relative to the diameter of an entry and exit hole to that chamber, ensures that pressure pulses entering and attempting to pass through such a chamber, die away. The death of pressure waves is relative to a near "cube" law exponent, by distance from entry point to the nearest point for reflection. So that a pressure wave, entering through a small hole, finding itself in a chamber, say 12 times the diameter of the entry hole, will die away to the extent that what is left of the pressure wave, will hardly find its way out of the outlet. The bladder, that is the liquid chamber, is large diameter. Large diameter membranes have good response characteristics to changes in pressure that are small.
PipeHugger pulse dampeners are safely closed by tamper-proof segmental lock rings that are retained by a set or boss on the dampener end-plug, such that the ring can not be removed without first de-pressurizing the damper of its pre-fill cushion gas spring. The ratios of dimensions with these "lock ring" pulsation dampeners enable the safe depressurization of the energy contained in the cushion gas, prior to vessel failure pressure. PipeHugger dampeners have an end face that is machined to an ANSi flange stud bolt pattern and a raised face. To achieve flow through capability, these capsular dampeners are typically mounted on multi port base blocks. Thru-flo enable pressure pulse and transient spike interception. Released from base block by 4 screws only. Simply remove 4 bolts.
PipeHugger High Pressure Pulsation Dampeners with Elastomer Bladder
Pulsation dampeners for smoothing industrial pipe systems, with flange face or, "O" ring & piping base. For flow fluctuation and interception of system pressure waves in process fluids that do not require the use of PTFE diaphragms. Pulse dampener is safely closed by tamper-proof segmental lock rings that are retained by a set or boss on the end-plug, such that the ring can not be removed without first de-pressurizing the damper. The ratios of dimensions with these "lock ring" Dampeners enable the safe depressurization of the energy contained in the cushion gas, prior to vessel failure pressure.
Cost saving with "liquid inside" the bladder dampeners only need the vessel shell, which house the inert Nitrogen pre- filled cushion, to be made from carbon steel. This damper construction cost saving is spent on having a larger diameter. The large pulsation dampener diameter successfully attenuates pressure waves, traveling at 3600 mph that are force into it by the multi-port piping bases. Pulsation dampeners designed with liquid in the bladder, only
require a base plug, liquid contact part, and bladder to be compatible with corrosive system liquids, as opposed to the entire vessel being high cost metals.
