Abstract

952,478. Joint-making packings; pipe joints. SULZER FRERES S.A. Dec. 19, 1960 [Dec. 23, 1959], No. 43603/60. Headings F2B and F2G. An annular seal comprises a plastically or elastically deformable sealing substance 33, Fig. 3, in the form of a soft metal such as cadmium, silver, silver alloy or lead-indium alloy, contained in a relatively rigid body 32 in such a manner that, when the seal is compressed between parts to be sealed, e.g. of a tank or pipeline, the sealing substance is deformed in opposite directions towards, and forms an effective seal with, the sealing surfaces of both parts. The body consists of a ring and the sealing substance is contained in annular grooves in opposite faces thereof. In modifications (a) the body has an H cross-section, Fig. 5, which is more readily deformable in the vertical than in the horizontal direction; (b) the sealing substance 63, Fig. 6, is contained in cavities, grooves 64 being provided for communication with check bores 65 in the parts to be sealed; (c) the body consists of two rings 72 of lenticular cross-section, Fig. 7, inserted in trapezoidal grooves in the adjacent parts; (d) the sealing substance is enclosed in a tubular body, Fig. 12, and passes into grooves 102 through bores 100 or slots 101; (e) the sealing surfaces of the seal, Fig. 9, are separated by check grooves 65.
