End loop spacer for parallel piping, especially in heat exchangers

摘要

The spacer forms a loop (4) in flexible synthetic piping, and has at least one continuous web (1) with omega-shaped openings (2). One side of the web has elements (3) whose shapes are matched to those of the loops which are to be formed, and the other side has reinforcing to align the piping in a parallel manner. The elements are arranged inside a loop in pairs, at the web openings. Each element is shaped so that it has flexural rigidity, and a second continuous web may be arranged near to the first, in the direction of the loop. Each pair of elements may be connected by a web, and an additional omega-shaped opening (8) may be arranged on the first and/or last moulding (7), and/or on the second web and on the element. The first and last elements may also have additional reinforcing (9).
