ABSTRACT:
An elastomeric sealing ring is provided for sealing an end of a pipe unit of the kind comprising a pipe, heat-insulating foam material surrounding the pipe and an outer tubular jacket and in which the pipe projects beyond the ends of the foam material and the jacket projects likewise, but for a shorter distance. The sealing ring is of U-section with a radially disposed base and inner and outer coaxially projecting flanges and has an annular groove formed in the base and extending into the outer flange. In use, the inner flange tightly surrounds a respective pipe end part of the pipe unit, the base is either seated against or spaced from the corresponding end of the foam material and the corresponding jacket end part extends into the annular groove. When two or more pipe units fitted with such sealing rings are joined end-to-end, the interconnected pipe end parts or each joint may be surrounded by heat-insulating foam material extending into contact with or spaced from the bases of the respective sealing rings and this foam material may be surrounded by a tubular outer cover.
