Method of installing liner assembly for pipeline repair or reinforcement, and liner assembly and steam generator for same

A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including an outer tubular liner and an inner inflatable bladder positioned longitudinally within the tubular liner, the tubular liner being wetted with a curable compound; introducing fluid into the inflatable bladder so that the inflatable bladder expands to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition for a time period sufficient for the tubular liner to cure; and deflating the inflatable bladder and retrieving at least a portion of the liner assembly from the pipeline.

Apparatus and method to repair the junction of a sewer main line and lateral pipe
10683960 · 2020-06-16 · ·

A liner assembly and method for lining a damaged pipe junction between a main and lateral pipe is provided. The liner assembly includes a main liner member and a lateral liner tube. A collar disposed near the juncture between the main liner member and lateral liner tube is impregnated with a liquid hydrophobic or hydrophilic material capable of curing in a flexible or rigid state with the material expanding in the presence of water. The hydrophobic or hydrophilic material can also be applied without the use of the collar. When the liner assembly is pressed against the main and lateral pipes, a portion of the hydrophilic or hydrophobic material is forced into the damaged pipe junction.

Method for Renovating the Interior of a Hollow Structure

A method for renovating the interior of a hollow structure such as a sewerage pit (1) is described. The method provides an access opening (16) to the hollow structure (1); provides a plurality of material sheets (3) comprising reinforcing fibers and a curable resin composition through the access opening (16) and against a wall (11a, 11b) of the hollow structure (1); and provides an inflatable pressure means (4a, 4b) within the hollow structure (1). The pressure means (4a, 4b) are inflated against the wall (11a, 11b). A curing means (6) is then provided within the hollow structure (1) for curing the resin composition; and the resin composition is cured to harden the material sheets and provide a renovated interior of the hollow structure (1).

Membrane lamination of three-dimensional (3D) article
10661543 · 2020-05-26 · ·

Embodiments provide a lamination machine and lamination process for laminating a membrane to a three-dimensional (3D) target surface of an article, such as a footwear article, glove, clothing article, backpack, or other article. The lamination machine may include an inflatable former that is permeable to air. The inflatable former may have a shape that generally corresponds to a shape of the target surface. The membrane and target surface may be arranged on the former, with a heat-activated adhesive disposed between the membrane and the target surface. The lamination machine may further include a pump to pump heated compressed air into the former. The heated compressed air may inflate the former to press the membrane against the target surface and to activate the adhesive to bond the membrane to the target surface.

Fuel Cell Liner Installation Device And Method Of Use
20240083102 · 2024-03-14 ·

A fuel cell liner installation device for properly installing fuel cell liners in an aircraft includes a bladder, which is flexible. A connector attached to the bladder is selectively connectable to a source of pressurized gas. In a collapsed state, the bladder is insertable into a cavity in a hull of an aircraft. The cavity is defined by a plurality of stringers that is lined with a plurality of fuel cell liners. Upon inflation, the bladder is sized and shaped substantially complementarily to the cavity and exerts a force upon the fuel cell liners to maintain the fuel cell liners in position as adhesive, which is positioned between the fuel cell liners and the stringers, cures. The bladder then can be deflated and removed from the cavity, positioning a user to install a fuel cell in the cavity.
