Abstract

1343602 Pipe couplings; repairing pipe joints WILLIAM PRESS & SON Ltd 22 Nov 1971 [23 Nov 1970 25 March 1971] 55653/70 and 7795/70 Headings F2G and F2P In order to make defective joints 3 tight, a segmental sleeve 6 can be expanded, by bolts 8, to squeeze elastomeric seal 4a, 4b, 5 against the pipe wall, at either side of the joint. The segments 6a may be of hard grade nylon. When the joints, as in, for example, a cast iron gas main, have become misaligned, two axially spaced annuli (50, Figs. 5 and 6, not shown) may replace the sleeve 6 and the flexible web (56), analogous to web 5, accommodates the joint misalignment.
