Example Embodiment

[0059] The pipe coupling 100 includes a tubular outer casing 102, a tubular inner casing 104 and a tubular sealing gasket 106. The tubular outer casing 102 is formed of rolled steel and has a longitudinal gap 108. The shell is folded back on itself at its free end and welded at 110 to form a loop 112 along the opposite edge of the longitudinal gap 108. A pin 114 is inserted in the ring. The tension screw 116 passes through a transverse hole in one of the pins 114 into a threaded transverse hole in the other pin of the pins 114 to connect the two free ends of the outer shell 102 to each other.

[0060] A slot 118 is cut in the ring 112 to provide space for the screw. The axial end edge of the housing 102 is bent inwardly at a right angle to form an annular flange 120.

[0061] The tubular inner casing 104 is formed of rolled steel and has a longitudinal gap. The axial end edge of the inner housing 104 is bent inwardly at a right angle to form an annular flange 122. The inner shell

Abstract

The present invention relates to fire-resistant pipe couplings (100) for connecting together two plain-ended pipes in a fluid-tight manner. The pipe coupling (100) comprises: a tubular casing comprising: an outer tubular casing (102); and an inner tubular casing (104), fitting entirely inside the outer casing (102); a tubular sealing gasket (106) disposed within the inner tubular casing (104); andmeans (116) for tensioning the casing around the gasket (106). The casing further comprises: at least one layer of fire-resistant material (124) disposed between the inner (104) and outer (102) casings; and at least one layer of thermally-insulating material (128) disposed between the tubular sealing gasket (106) and the inner casing (104), whereby the outer casing (102) and tubular sealing gasket (106) are thermally insulated from one another.
