  • Method of manufacturing a pipe coated with a resin layer on the inner surface thereof
    Patent number: 5356665
    Abstract: A pipe coated with a resin layer on the inner surface and a method for manufacturing the pipe. According to the method, a resin mixture including thermal melting fluoro resin and fluorine elastomer is applied to the inner surface of a pipe member. The resin mixture is thermally treated on the inner surface of the pipe member to form a mesh like pattern so that a resin layer of a predetermined stripping strength is obtained.
    Type: Grant
    Filed: February 16, 1993
    Date of Patent: October 18, 1994
    Assignee: Hitachi Cable, Ltd.
    Inventors: Kuniaki Seki, Shinichi Nishiyama, Hajime Abe, Noboru Hagiwara

  • Method for manufacturing metallic tube members
    Patent number: 4838063
    Abstract: A method for coating the inner surface of a metal tube with a metal layer consisting of one or more metals, the metal layer having a melting point lower than that of the metal tube, the method comprising;thinly applying a mixture consisting of a low melting point powder and a flux composition to the inner surface of the tube by the use of a plug, andheating the tube to which the mixture has been applied at a temperature being at least the melting point of the low melting point powder but lower than the melting point of the metal tube to fuse the powder.
