The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.

A method for producing a pre-insulated pipe, comprising inserting a length of jacket pipe (10) into a guide channel (110) having a front end (111) and a rear end (112); fixing said length of jacket pipe (10) in said guide channel (110); providing a first end (21) of a length of insulated inner piping (20), said length of insulated inner piping comprising a length of inner pipe surrounded by at least one layer of compressible insulation material (26); inserting, at said front end of said guide channel, into said length of jacket pipe, said first end of said length of insulated inner piping (20); applying an overpressure at least in an interior of said length of jacket pipe (10), around the inserted first end of the length of insulated inner piping (20); and moving said first end of said length of insulated inner piping (20) to said rear end of said guide channel (110); wherein said overpressure is such that said at least one layer of insulation material (26) is radially compressed; removing said overpressure to fix said length of insulated inner piping (20) in said length of jacket pipe (10) in order to form a pre-insulated pipe.

The application relates to a method for producing a double-walled pipe (1) and a pipe (1) of this type, having an outer pipe (3) which is press-fitted with an inner pipe (2) consisting of a corrosion-resistant alloy, wherein an adhesive (4) is inserted at least in regions between the outer pipe (3) and the inner pipe (2), wherein, after adhering the inner pipe (2) with the outer pipe (3), the inner pipe (2) and the adhesive layer (4) are removed at the pipe ends, and the inner side of the outer pipe (3) is plated via an integral connection with the inner pipe (2).

In various examples, a method of making a guidewire is described. The method includes placing a polymer jacket over a core wire. The core wire includes a first portion having a first profile and a second portion having a second profile. The first profile is smaller than the second profile. Heat is applied to the polymer jacket and the core wire to reflow the polymer jacket and fuse the polymer jacket to the core wire, wherein the polymer jacket forms a layer of substantially uniform thickness along a length of the core wire. In some examples, a guidewire made using the method is also described.

Examples are disclosed that relate to textile coverings for electronic devices and methods for manufacturing textile coverings for electronic devices. In one example, a textile covering for an electronic device comprises one or more structural fibers woven into a seamless tube, the seamless tube configured to encircle at least a portion of the electronic device. The textile covering also comprises one or more heat-shrink fibers and/or one or more adhesive fibers woven into the seamless tube. The heat-shrink fibers shrink when the seamless tube is heated above a threshold temperature, thereby constricting the seamless tube around the electronic device. The one or more adhesive fibers adhere the textile covering to the electronic device.

Corrosion on industrial infrastructures can be prevented or arrested using a multi-stage system and method having an optional epoxy primer, a thermoplastic layer, a self-amalgamating water-cure wrap, and a top coat of epoxy. The resulting impervious barrier resists corrosion and withstands abuse from the elements.

A polymeric film or laminate comprising the same is applied to at least a portion of a surface of an underlying article to provide, for example, desired surface characteristics. To assist in such application, a polymerizable composition is coated onto at least one of the surface of the polymeric film or the laminate and the surface of the article. The polymerizable composition is then polymerized with the polymeric film or laminate positioned thereover to form a sufficiently polymerized interlayer between the polymeric film or laminate and the underlying surface in resulting articles. Ease of removal and/or repair of polymeric film and laminates comprising the polymeric film that are so applied is facilitated.

A method for producing a pre-insulated pipe, comprising inserting a length of jacket pipe (10) into a guide channel (110) having a front end (111) and a rear end (112); fixing said length of jacket pipe (10) in said guide channel (110); providing a first end (21) of a length of insulated inner piping (20), said length of insulated inner piping comprising a length of inner pipe surrounded by at least one layer of compressible insulation material (26); inserting, at said front end of said guide channel, into said length of jacket pipe, said first end of said length of insulated inner piping (20); applying an overpressure at least in an interior of said length of jacket pipe (10), around the inserted first end of the length of insulated inner piping (20); and moving said first end of said length of insulated inner piping (20) to said rear end of said guide channel (110); wherein said overpressure is such that said at least one layer of insulation material (26) is radially compressed; removing said overpressure to fix said length of insulated inner piping (20) in said length of jacket pipe (10) in order to form a pre-insulated pipe.

An armor for a heat shrink kit for joining a first length of heating cable and a second length of heating cable. The armor includes a spring configured to be positioned over at least a portion of the heat shrink kit, a first fastener configured to couple the spring to at least one of the first length of heating cable and the heat shrink kit, and a second fastener configured to couple the spring to at least one of the second length of heating cable and the heat shrink kit. The armor is configured to provide impact protection to the heat shrink kit.

A microcatheter comprising an inner layer, a strike layer and an outer layer and a braided skeleton located between the inner layer and the outer layer, wherein the inner layer is made of Polytetrafluoroethylene (PTFE) and has a thickness of 0.0015 inch or less, wherein the strike layer includes a polyether block amide and has a thickness of 0.001 inch or less, and wherein a distal portion of said outer layer is made of polycarbonate-based thermoplastic polyurethane having a shore of 90A or below.
