Abstract (en)
[origin: CA2703031A1] The invention relates to a connection system for double-walled pipes (1, 2) comprising an inner pipe (12, 22) made of a stainless steel and an outer pipe (11, 21) which surrounds the inner pipe (12, 22) and has a greater tensile strength than the inner pipe (12, 22), wherein threads (13, 23) are formed at the ends of the outer pipe (11, 21), and also comprising a screw-type sleeve (3) with internal threads (31, 32) which correspond in terms of design to the external threads (13, 23), and comprising a sealing ring (4) which is arranged in the sleeve (3), is formed from a stainless material and, in the screwed-on state, seals the sleeve (3) with respect to the medium transported through the inner pipe (12, 22).
