摘要： A pipe coupling for coupling together two pipes in a fluid-tight manner includes a tubular casing, a tubular sealing gasket located within the casing, and screws for tensioning the casing around the gasket. The casing includes an inner tubular casing and an outer tubular casing, both of metal. A layer of fire-resistant thermally-insulating material is disposed between the inner and outer casings to form a fire shield.
