A disconnectable union for fluid piping is provided in which a pre-load dependent first seal between disassemblable union members is coaxially related to a second seal operable independently of the pre-loading of the first seal such that the second seal independently contains any fluid that comes in contact with it even if such fluid contact is due to diminution of the pre-loading of the first seal. Various flange joint configurations and seal constructions are disclosed for both plastic lined and unlined metal pipe.


A disconnectable pipe union comprising in combination first and second union members, means for establishing between said union members a first circumferential seal whose sealing effectiveness is a function of its pre-loading and which is fluid-tight when pre-loaded above a given level, means constructed and arranged to be placed under tension to draw said first and second union members toward each other to provide at least said given level of pre-loading for said first seal, said union members being related to said means for establishing a first seal su...
