Abstract

A spacing spiral for a coaxial tube system in which, in use, there is a temperature gradient between radially successive tubes of the coaxial system e.g. a coaxial tube system, constituted by an electric cable operated in a super-conductive state, or a pipeline for conveying a heated or cooled fluid medium, comprises individual cords (1, 2, 3 & 4) assembled in the form of a plait. Preferably the cords are of circular cross-section. The cords may for example be of metal and/or synthetic material. Furthermore, individual cords may be of composite construction, e.g. comprising synthetic and metal threads twisted together. A particularly useful specific construction employs four individual cords which follow an undulating course along the length of the spiral, two of the four cords (1 & 2) being disposed generally in one plane and the two other cords (3 & 4) being disposed generally in a plane at right angles to the first one. The plaited spiral enables heat transfer (in the radial direction of the coaxial tube system) to be kept down to a particularly low value without loss of flexibility. <IMAGE>

1. ДИСТАНЦИОННАЯ СПИРАЛЬ, преимущественно для коаксиальной системы труб с температурным перепадом между трубами, включающая собственно спираль, установленную в пространстве между трубами, о т л и ч а ю щ а я с я тем, что, с целью уменьшения тепловых потерь без уменьшения гибкости, спираль выполнена из сплетенных в виде косы Ьтдельных ' прядей.1. REMOTE SPIRAL, mainly for a coaxial pipe system with a temperature difference between the pipes, including the actual spiral installed in the space between the pipes, so that in order to reduce heat loss without reducing flexibility , the spiral is made of braids woven in the form of a braid of individual 'strands. 2. Спираль по π. 1, о т л и чающая с я тем, что в случае выполнения спирали из четырех отдельных прядей последние волнообразно проходят вдоль спирали, причем две пряди расположены в одной плоскости, а две другие - в перпендикулярной к ней плоскости.2. The spiral along π. 1, with the fact that in the case of a spiral made of four separate strands, the latter pass in waves along the spiral, with two strands located in one plane and the other two in a plane perpendicular to it. 3. Спираль по пп. 1 и 2, о т л и- чающаяся тем, что поверхность отдельных прядей выполнена шероховатой. §3. The spiral according to paragraphs. 1 and 2, on the basis of the fact that the surface of the individual strands is made rough. § J074416 >J074416> •·• ·
