  • Patent number: 4743035
    Abstract: A seal system between two metal pipes (1, 2) flanges (4, 5) exposed to extreme temperatures, includes at least one elastic annular lip (11, 12) which is held by one of the flanges, with its highest point (10) in contact with the other flange to form a seal line when the flanges are assembled. The lip (11, 12) is an integral part of one of the flanges (4, 5) and it is made by lathing two grooves (13, 14; 17, 18) with one groove (13, 17) radially penetrating the cylindrical surface (15, 19) of the flange, and the other groove penetrating perpendicularly to the former in the flat surface (7, 8) of the flange to define a thinned area (16, 20) between the two grooves to ensure the elasticity of the lip (11, 12).
