Liners and tube supports for industrial and chemical process equipment

A liner assembly for industrial and chemical process equipment comprising, a metallic substrate consisting essentially of iron group metals and alloys thereof, a metallic liner sheet overlying said metallic substrate, and liner sheet and substrate having an aperture therethrough, a metallic sleeve extending through said aperture and being sealed to said liner sheet by a circumferentially continuous metal joint consisting essentially of a weld or braze, said liner sheet and sleeve each consisting essentially of titanium, zirconium, hafnium, tantalum, columbium, vanadium, and alloys thereof which have a coefficient of thermal expansion differing substantially from that of said metallic substrate and if alloyed with iron are brittle, a metallic bushing shorter in length than said sleeve and received in said aperture between and in direct engagement with and bearing on both said sleeve and substrate and having a coefficient of thermal expansion greater than the coefficient of thermal expansion of said sleeve and said substrate, an elastomer interposed between and bonded to at least a substantial portion of one face of an imperforate portion of said liner sheet and also bonded to an underlying coextensive portion of an adjacent face of said substrate to adhere said liner sheet to said substrate and permanently retain said liner sheet on said substrate without any wrinkling and buckling of said liner sheet, and a continuous ring of an elastomer overlying an edge of said bushing and bonded to a portion of the sleeve extending beyond said bushing and to the adjacent faces of said liner sheet and said substrate so as to seal said bushing from a corrosive environment.

A liner assembly for industrial and chemical process equipment comprising:

• a metallic substrate consisting essentially of iron group metals and alloys thereof, a metallic liner sheet overlying said metallic substrate, said liner sheet and said substrate having an aperture therethrough, a metallic sleeve extending through said aperture and being sealed to said liner sheet by a circumferentially continuous metal joint consisting essentially of a weld or a braze, a metallic tube telescopically received in said sleeve and sealed to said sleeve by a circumferentially continuous metal joint consisting essentially of a weld or a braze, said liner sheet, sleeve, and tube each consisting essentially of titanium, zirconium, hafnium, tantalum, columbium, vanadium, and alloys thereof which have a coefficient of thermal expansion differing substantially of that of said metallic substrate and if alloyed with iron are brittle, an elastomer interposed between and bonded to at least a substantial portion of one face of an imperforate portion of said liner sheet and also bonded to an underlying coextensive portion of an adjacent face of said substrate so as to adhere said liner sheet to said substrate to permanently retain said liner sheet on said substrate without any wrinkling and buckling of said liner sheet, and an elastomer received in said aperture between and bonded to both said sleeve and to the adjacent faces of said liner sheet and said substrate so as to mount said sleeve and said tube telescoped therein on said substrate.
