  • Method of strengthening the connection between pipe sections in high pressure pipelines
    Patent number: 8449800
    Abstract: A preventative maintenance method of strengthening the connection between high pressure, in situ piping. An encapsulation mold is installed over a properly functioning, non-leaking coupling or joint interconnecting pipe sections carrying gas in excess of 60 psi. A resin sealant having tensile strength in excess of 3000 psi fills the mold, so that it circumscribes the coupling and adjacent portions of the pipe sections extending from the coupling, forming a permanent bond to the coupling and pipe sections. The method prevents high pressure pipe connection pullout, which otherwise could lead to catastrophic failure.
