PIPE-LINER EVERSION SYSTEM AND METHOD
20170326784 · 2017-11-16 ·

A pipe-liner system for lining a pipe and methods of use thereof. A continuous, eversible extended liner is formed from a pipe-liner attached to an extender-tube via a substantially leak-proof connection there between. Lengths of the extender-tube and the pipe-liner are each chosen so that the pipe-liner is caused to be accurately positioned within the pipe upon everting the extended liner into the pipe by a pressurized fluid. The pipe-liner is held against an interior surface of the pipe being lined by inserting an inflatable bladder into the extended liner and filling the bladder with pressurized fluid. When a resin in the pipe-liner has hardened, the bladder is removed and the extender-tube is detached from the pipe-liner.

Systems and methods for rehabilitation of water conduits and other conduits

Methods and systems for installation of a liner inside a conduit (e.g., water pipe) to transport a fluid (e.g., potable water) to rehabilitate the conduit, in which the liner can be installed, and thus the conduit can be rehabilitated, more efficiently, including, for example, by further reducing an extent of digging that may have to be done, by testing more readily (e.g., pressure-testing for watertightness or other fluid-tightness once installed), and/or by adapting to a cross-sectional size of the conduit. Also, the liner may be thinner, interact better (e.g., less) with the fluid flowing through the conduit, and/or be otherwise designed to enhance its use and performance.

System and Method for Retroactively Lining a Vertical Trash Chute
20220118679 · 2022-04-21 · ·

A system and method of retroactively lining a vertical trash chute in a building. A tubular fabric liner is provided having a first open end and a second open end. The tubular fabric liner is infused with a resin. A first plug assembly is attached to the first open end. The tubular fabric liner is pulled through the vertical trash chute to position the tubular fabric liner in the trash chute. A second plug assembly is attached to the second open end. The tubular fabric liner is inflated. As it expands, the tubular fabric liner presses against the interior of the trash chute. This condition is maintained until the resin cures and bonds the tubular fabric liner to the trash chute. Once cured, the plug assemblies are removed, the tubular fabric liner is trimmed, and trash chute access openings are cut through the cured liner.

AIRCRAFT FLUID CONDUIT COMPRISING THERMOPLASTIC PIPING AND CONNECTOR

Securing Polymer Liners within Pipes
20220212395 · 2022-07-07 ·

A method of manufacturing a length of lined pipe comprises inserting a radially-contracted liner pipe into an outer host pipe. Injector needles are inserted through an end of the outer pipe into an annular gap between the pipes. Adhesive is injected between the pipes at locations inboard of the end of the outer pipe. After withdrawing the injectors, at least a portion of the liner pipe is expanded to close the gap and to bond the pipes together via the injected adhesive. Shims may be inserted into the gap between the pipes. A portion of the liner pipe inboard of the shims may be expanded radially while the shims constrain local radial expansion of an outboard portion of the liner pipe to maintain the gap for accommodating the injectors. Withdrawing the shims after injecting the adhesive allows radial expansion of the outboard portion to close the gap between the pipes.
