Hello all,
I am wondering about how the high-pressure mechanical/corrosion test systems in aqueous/gaseous environment (Eg: tensile, creep, fatigue testing in some environments) are made leak proof at the moving part boundaries? Especially when the test vessel is filled with some solutions, how the pull rod - autoclave boundaries are made leak proof? What kind of sealing are used here? Kindly provide me so some design references.
Thank you for your assistance.
I have no experience, with this scenario, but suggest you start by defining the required performance envelope - maximum pressure, temperature range, (if variable), the aqueous/gaseous materials to be used, since those could impact whatever seal material, and the maximum planned individual test duration, in case seal life is limited by chemical interaction with the aqueous/gaseous environment. Then, review the test setup in Fig 1, at the link below, for suitability; it avoids moving part seals by using an expanding bellows type of chamber.
