A New Method of Housing Flanges Sealing under High Internal Pressure

The article presents an advanced method providing housing flanges sealing with a minimum decrease of joint stiffness compared to flanges sealing joints with flexible pads. Such factors as surface roughness, waviness, shape defect, and flanges dimensions themselves effect on joint stiffness of housing components. Using anaerobic materials as a means of sealant can successfully seal flange butt joint. Experimental research results of a plane flange sealing under differential pressures up to 120 bar, and using anaerobic material LOCTITE manufactured by Henkel, are given. The experiment showed positive result of joints sealing with the use of anaerobic sealant.
