Abstract

1310513 Pipe couplings BTR INDUSTRIES Ltd 30 June 1970 [1 July 1969] 33136/69 Heading F2G A coupling for two pairs of pipes 1, 2, 17, 18 has two parts each having an inner and outer member 27, 28 having coaxial sealing surfaces, the ends of inner pair of pipes 1, 17 being within the inner sealing surfaces and the outer pair of pipes 2, 18 between the inner and outer sealing surfaces. The pipe 18 may be coaxial with the duct 17, or be a single or series of pipes placed around the pipe 17. A ring 3 having a series of passageways 21 separates the members 27, 28 and limits the relative axial movement of the members 27, 28 on coupling. The ring 3 may be retained by a circlip as shown or held in threaded engagement with member 28, Fig. 5 (not shown). Sealing between the coaxial surfaces may be by means of rings 23 on tapered surfaces 20 on either the inner and/or outer surfaces Alternatively, Fig. 6 (not shown), a grooved spigot fitting within a plain socket may be used. The union nut 15 for drawing together the coupling may be replaced by a gland nut or bolted flanges.
