Abstract

1417305 P.T.F.E. coated pipes PRODUITS CHIMIQUES UGINE KUHLMANN 24 Oct 1973 [6 Nov 1972] 49464/73 Addition to 1275392 Heading B2E [Also in Divisions B5 and F2] The reinforced pipe of Specification 1275392 comprising a body of PTFE with a perforated metal reinforcement, the PTFE being isostatically moulded or coated onto the reinforcement, is modified in that the reinforcement is of expanded metal, Fig. 1, which can be stretched in a direction F and is so arranged in the pipe wall that this direction F, Fig. 2, is perpendicular to the main axis X-X of the pipe. A modified pipe, Fig. 7, has smaller and larger diameter portions 18, 19 connected by a frusto-conical bridge part 20.
