• Eliminate pressure instrument failure due to hydraulic or pneumatic shock
• Smooth out pressure impulses and fluctuations
• Remove harmful solids from actating fluid
• Assure steady average pressure readings

The key to the superior performance and efficiency of chemiquip pressure snubbers is the corrosion resistant porous membrane used as the snubbing element. A product of electric furnace technology, the porous metal disc is fabricated by sintering prealloyed, type 316 stainless steel powder, or other corrosion resistant materials, ina n electric furnace. The powder particles are firmly welded at their tangent points to create a mechanically stable structure with a tensile strenght of 20,000 psi. There is absolutly no evidence of particle migration regardless of the magnitude of the pressure, shock or longevity of service.

The particle size of the powder determines the pore opening. The standard flow capacity of the snubber is adjusted by using the pore size most suited to the viscosity of the pressure-actuating

medium. Various pore sizes are available for use with oils, water, gases or mercury.

With a chemiquip snubber positioned up-stream of a pressure sensitive instrument, the instrument response to the system pressure changes is at a rate in proportion to the pressure differential across the snubber element. A moderatly rapid, smooth response of the pressure sensitive instrument is obtained, free of of transient surges or pulsations. The snubber is calibrated to give and equilibrium reading, up-scale or down-scale, in approxamitely 2-3 seconds.
