Abstract

850,421. Reinforced pipes. LONZA ELECTRIC & CHEMICAL WORKS Ltd. June 9, 1958 [June 8,1957], No. 18375/58. Class 99(2) In a process for the production of tubes, a resin impregnated fabric strip and a strip of closed cell cellular polyvinyl chloride are wound up on a former and bonded together by a hardenable synthetic resin composition so as to form a tube having at least one layer of cellular strip and at least one layer of resin-impregnated fabric strip. The cellular strip can be made from polyvinyl chloride with or without a maximum of 20% of plasticizer or copolymers of vinyl chloride by dissolving gases in the material and expanding these gases by a high pressure process. The layer of fabric e.g. glass fibre, textile, or woven material, can be coated or impregnated with a hardenable synthetic resin and spirally wound upon a former followed by a strip of cellular material and then a further layer of fabric impregnated with the polyester. The layers are then heated by infra-red irradiation until the whole tube hardens. Specification 694,964 is referred to.
