  • Manufacture of pipes
    Patent number: 11697881
    Abstract: The present invention relates to a method of manufacturing a pipe, which method comprises cold-gas dynamic spraying of particles onto a suitable support member thereby producing a pipe, and separating the pipe from the support member.

  • Method of forming seamless pipe of titanium and/or titanium alloys
    Patent number: 10005129
    Abstract: This invention relates to a method of forming sections of seamless titanium or titanium alloy pipe. The method involves providing a substrate for forming pipe and a sleeve of a section of pipe on the substrate. The pipe section has an end from which the substrate projects. The pipe is formed by spraying particles of titanium or titanium alloy generally parallel to a longitudinal axis of the substrate to impact a face of the end and to cause particles to bond to and to accumulate on the pipe end to form pipe. The method further involves moving formed pipe longitudinally relative to the substrate to remove formed pipe from the pipe-forming substrate and continuing to spray titanium or titanium alloy particles onto the end face to cause further pipe to form continuously and integrally with the formed pipe. This enables a seamless titanium or titanium alloy pipe to be formed of any desired length.
