  • System, method, and apparatus for pre-tensioned pipe for load-sharing with composite cover
    Patent number: 8440034
    Abstract: A pipe is wrapped with a composite to form a pre-stressed interface to facilitate load sharing between the materials. Prior to being wrapped, the pipe is placed in tension via hydraulic devices or the like. Alternatively, a combination of cured and uncured composite wraps is used in proximity to each other to apply compressive stress to the pipe. In addition, the pipe may be subjected to cold temperatures to change its dimensions prior to being wrapped with a composite material.
    Type: Grant
    Filed: February 28, 2011
    Date of Patent: May 14, 2013
    Assignee: Vetco Gray Inc.
    Inventors: Joseph W. Pallini, Fife B. Ellis, Danny L. Havelka, Brian N. Munk
