摘要:
A repair wrap for repairing or strengthening an item. The repair wrap includes a fabric, where the fabric includes one or more fibers. The repair wrap also includes a film disposed laterally within the fabric. The repair wrap further includes a hardening material disposed in the fabric. The fabric is configured to be wrapped around a portion of an item. Curing the hardening material is configured to form a shell about the portion of the item.

A reinforced pipe section comprises a metal pipe, a layer of dry fibers disposed around the metal pipe, and an external liner covering the layer of dry fibers. A method of manufacturing a reinforced pipe section comprises wrapping a layer of dry fibers over a metal pipe, and covering the layer of dry fibers with an external liner, thereby forming a first dry fiber wrapped metal pipe. A method of reinforcing a degraded metal pipe comprises wrapping the degraded metal pipe with a layer of dry fibers to increase the hoop strength of the degraded metal pipe, and covering the layer of dry fibers with an external liner.
摘要:
A system and method of repairing a pipe including securing a reinforcing material, such as a dry fiber structure (e.g., a carbon fibers) to the surface of the pipe. A polymeric material is placed on top of the reinforcing material, self-penetrating the dry fiber structure. The polymeric material substantially saturates the reinforcing material and cures to form a reinforced polymeric composite which may increase or restore the pressure rating or operating pressure capacity of the pipe. Optionally, an outer containment component, such as a sleeve, shell, box, wall, outer pipe, and so on, may be installed around the reinforcing material prior to introduction of the polymeric material. In this case, the polymeric material may be placed (i.e., poured) into the interior of the containment component on top of the reinforcing material.

A tool is disclosed comprising a thin, ribbon-like but semi-rigid material which can be “snaked” in between ductwork and the surface to which it is attached. The tool is configured to enable the temporary attachment of a tape material thereon. Further, the tape material includes a non-adhesive “release tape” attached to the adhesive portion of the adhesive tape. Using the method and apparatus described herein, a user can insert the tape, with the protective tape release thereon, around the ductwork, release the tape and remove the tool, and use the tool as it is being withdrawn to urge the adhesive tape onto the seam being taped.

A method and kit for repairing a gas leak in a pipe containing natural gas. The natural gas repair kit includes a leak sealant, a pressure sealant, and an encapsulator. The method for repairing the gas leak includes the act of applying a leak sealant over the leak in the pipe. The method further includes the act of wrapping a pressure sealant around the pipe near the leak. The pressure sealant should enclose and contact the leak sealant. Additionally, an encapsulator should be wrapped around the pipe near the leak. The encapsulator should contact the pressure sealant and the pipe.

Further, the polymeric material may be subjected to pressure to facilitate contact of the resin through the reinforcing material.

A wrapped and curing substrate is secured: with a strap. The strap has two clips, each having a prong. The prong of a first clip is slid in a first direction into a first portion of the wrapped substrate. A second clip is pulled away from the first clip over a substrate edge, and the prong of the second clip is slid into a second portion of the wrapped substrate in a direction opposite the first direction. In one embodiment, the first portion of the wrapped substrate is an overlapping layer of substrate, and the second portion of the wrapped substrate is the layer of substrate extending from underneath the overlapping substrate.

Reinforcing bands of high tensile strength filaments in a cured resin matrix are in the shape of a coil having a plurality of elastic convolutions for reinforcing a weakened pipe. Areas of depressions on the exterior surface of the pipe are filled with a load transfer filler material and the bands are coiled around the pipe with adhesive holding an innermost convolution of the coil to the pipe and subsequent convolutions of the coil to adjacent convolutions. A plurality of the bands are placed in abutment with one another to cover the entire weakened area of the pipe.
