Fire-resistant pipe coupling

A pipe coupling for coupling together two pipes in a fluid-tight manner, comprising:

• a tubular casing comprising:
• an outer tubular casing;
• and an inner tubular casing, fitting entirely inside the outer tubular casing;
• a tubular sealing gasket disposed within the inner tubular casing;
• and
• means for tensioning the tubular casing around the gasket, wherein:
• the tubular casing further comprises:
• at least one layer of fire-resistant material disposed between the inner tubular casing and the outer tubular casings, wherein the at least one layer of fire-resistant material or each layer of fire resistant material is a prepared strip of flexible material having a width greater than the width of the outer tubular casing, such that the prepared strip of flexible material or each of the prepared strips of flexible material extend radially inward at each end to form a skirt at each end, so that the prepared strip of flexible material or each prepared strip of flexible material has a pair of skirts, and the pair of skirts of the prepared strip of flexible material or each pair of skirts of each prepared strip of flexible material is configured to extend toward an outer surface of one of the pipes being coupled together;
• and
• at least one layer of thermally-insulating material disposed between the tubular sealing gasket and the inner tubular casing,
• whereby the outer tubular casing and tubular sealing gasket are thermally insulated from one another.
