Abstract
550,448. Flexible pipes. WILKINSON, B., DOUGLAS, W. D., and STANDEN, G. June 6, 1941, No. 7188. Addition to 538,171. [Class 99 (ii)] A flexible selfsealing petrol pipe is made up of an innertube of a synthetic resin or rubber impervious to the action of petrol, a surrounding helical winding of non- metallic material such as regenerated cellulose, polyvinyl resin, or vulcanized fibre, a layer of self-sealing rubber such as that known by the Registered Trade Mark "Linatex," and an external protective covering. Fig. 1 shows a pipe composed of an inner tube 10 of polyvinyl resin which is built up on a mandrel and has wound around it a layer of fabric 11 coated inside with vinyl cement and outside with rubber cement, a helical winding 12 being then applied, and over that a layer of sponge rubber 13 and a second helical winding 14 staggered with respect to the winding '12 so that the sponge rubber becomes corrugated and prevents collapse of the tube upon flexure. The rubber 13 is coated on both sides with a cement such as that known by the Registered Trade Mark "Solufix," and two layers 15, 16 of " Linatex " applied and also covered with "Solufix." A helical winding 17 of hemp cord then resists the corrugating action, and an external covering of fabric 18 is applied, with a further cord binding 19. The envelope 18 is coated with dope or may be of fabric treated with neoprene, or of two layers of fabric with vulcanized rubber between them. The " Linatex " may be uncured, and an accelerator added to the cement, the whole being subjected to heat ; in such a case the covering 18 may be coated with fuel-resisting rubber. In a modification the outer covering may be of the material known by the Registered Trade Mark " Cellophane," and the helix 12 may be covered with a layer of cotton or rubber. The inner tube may be of thiokol. Specification 437,928, [Group V], is referred to.
