MSL Mars Rover – launch 2011, for the liquid Freon heat rejection system, Omnisafe 3/8” fittings JPL DAWN – Xenon Ion Propulsion, Asteroid Belt, Oct 2007, Omnisafe 1/8” fittings NASA Evolutionary Xenon…
OmniSafe Particle Study – Multiple Make Up
This is the equipment and procedure used to determine the quantity and size of the particles shed into the process stream, due to galling, as a legacy metal face seal fitting is tightened. Objectives Compare standard metal face seal fitting with the OmniSafe torque suppression fitting over the following criteria: Examine the sealing surfaces of…
Overtightening: OmniSafe vs. Legacy Face Seal Fitting
In the S.E.M. (top) the severe effects from over tightening on the sealing surfaces of a legacy face seal fitting are shown. In the S.E.M. (lower) using Omnisafe torque elimination, the seal area is not galled. One half turn past finger tight is a worst case scenario. At 5/8 turn past finger tight the gasket…
ITRS – 22 Nanometer Mode
These findings are in regard to 22 nm circuitry, which is currently in design for 2011-2012. For this circuitry we will be concerned with all particles >10nm. There are some new issues that may reveal a need for cleaner, torque elimination metal face seal fittings. One new challenge is that with these extremely small geometries,…
Electro Dispersive Spectra (EDS) of a New Gland & One Mating
* taken at the point indicated by the red arrow on the first S.E.M.s After checking the nickel peaks on the bottom EDS we notice much higher nickel reading. This higher signal is from nickel particles that are embedded into the torroid of the gland from the galled nickel gasket during tightening of the fitting….
Counter Rotational Displacement – Standard VCR vs. OmniSafe
How much rotation is transferred to the components connected by a “VCR type”* metal face seal fitting as it is tightened with a nickel gasket? This data below shows that the relative rotation of the components ranges from 6.7 to 18.2 degrees. This rotation is based on the plating inside the female nut and the…
