Abstract

1,039,073. Concentric pipes. SVENSKA FLAKTFABRIKEN A.B. March 12, 1965 [March 17, 1964], No. 10670/65. Heading F2P. A combined distancing and sealing element 1 for positioning relatively to each other two concentric spirally wound pipes 2, 3 comprises an annular member of U-shaped cross-section, the radially inner surface of which is provided with a part-spiral groove to accommodate the folded-over edges 7 of the inner pipe 3. Two axially extending, diametrically opposite walls are formed in the space between the legs of the U-shape to facilitate the positioning of the element between the pipes. The limbs of the member in its unmounted position diverge away from each other.
