Electro Dispersive Spectra (EDS) of a New Gland & One Mating

Torroid of a New SS316L Gland

After One Mating Using a Nickel Gasket*

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.

This reading is consistent and confirms the conclusions from the previous particle study and S.E.M.s
