A patch for a pipe includes a patch body that has an outer surface and an inner surface. The patch body is curved to correspond to the curvature of a pipe that may include a defect that is desired to be sealed. A plug extends from the inner surface of the patch and the plug is configured to fit within the defect while the inner surface of the patch is in contact with an outer diameter of the pipe. The patch is adhered to the pipe using a primer and an adhesive that is applied to the outer diameter of the pipe surrounding the defect, the inner surface of the patch, or to both surfaces. Attachment straps may wrap around the pipe and the patch as the adhesive sets to maintain contact between the pipe and the patch.

A coating repair device for repairing a defect in a paint or coating by forming a repair patch around and over the defect. The repair device comprising a flexible member having an inner section peripherally surrounded by an outer section, each section having top and bottom surfaces with the bottom surface of the inner section being recessed with respect to the bottom surface of the outer section, such that when the flexible member is, in use, placed on the surface of a coating to be repaired it defines a cavity with the surface. An injection through-hole extends between a top and bottom surface of the device for the introduction of repair material into the cavity, in use, and one or more relief through-holes extend between the bottom and top surfaces of the device through which, in use, displaced air or surplus repair material may flow out of the cavity.

In some implementations, an apparatus comprises a pipe, a stud that is forge-welded to the pipe, creating a forge-welded stud, a bracket that is operably coupled to the forge-welded stud, and a ladder support operably coupled to the bracket.

A method and apparatus for connecting pipe sections or repairing two separated pipe sections is provided, including for extruded chopped filament pipe (“ECFP”). An apparatus having a sealable connecting jacket is provided, which includes a mold configured to fit around a cut section of ECFP and receive a resin or other material through an input, and a curing system, such as a hot water intake surrounding the mold to heat and cure the resin forming the new pipe section.

A device for preparation of composite for on-site pipeline reinforcement includes: a temperature control stirring unit, an infiltration unit, and a vacuum unit communicated in sequence, the infiltration unit includes a spindle, reinforced fiber cloth, a flow-guiding net, and a vacuum bag film sleeved outside them, the spindle is stopped by two baffles, an adhesive feeding joint and an adhesive discharging joint are disposed at two ends of the spindle, respectively, the adhesive feeding joint and the adhesive discharging joint each includes an inner joint and an outer joint, sealing discs disposed at a junction between the inner joint and the outer joint, an outer wall of the inner joint and an outer side of the baffle are covered by a flow-leading net, and the flow-guiding net covered on the outer side of the baffle extends from an edge of the baffle into the adhesive storing compartment of the baffle.

Robotic tools, methods, and systems for repairing pipes in-situ are described. A robotic tool includes a body with an annular, cylindrical configuration with a first end and a second end opposite the first end, the body having an inner surface defining an axis; a printing arm attached to the inner surface of the robotic body using a track, the printing arm circumferentially movable along the inner surface of the body; a printing head attached to the printing arm, the printing head movable radially along the printing arm and axially relative to the printing arm; and a plurality of legs positioned at axial intervals around the robotic body, each leg pivotably attached to the robotic body at either the first end or the second end of the body and pivotable between an open position and a closed position.

The present invention proposes a split clamp (7), typical of trepanning operations in pipes, which allows the intervention with a tool (3) that makes a circular hole in the pipe (1) under analysis, removing layer by layer, until reaching the pressure barrier (2). With this, a sample of the layer of interest is removed to be forwarded for analysis. Such a clamp (7) has means to isolate the pipe (1) from the external environment, introduce the tool (3) and remove the same with the sample, also allowing tightness repair of the pipe (1).

A fire sprinkler system according to one aspect of the present disclosure includes a pipe having a first pipe portion and a second pipe portion. The first pipe portion includes a wall having a first wall thickness, and the second pipe portion includes a wall having a second wall thickness that is greater than the first wall thickness. The fire sprinkler system further includes structure coupled to the pipe and defining a sealed chamber between the structure and at least the first pipe portion, and a sensor for sensing a pressure in the sealed chamber. Example corrosion monitoring devices and methods for monitoring corrosion in pipe systems, including fire sprinkler systems, are also disclosed.

A repair system for repairing a polyolefin pipe containing a transitional film applied over and bonded to the pipe and a reinforcement system, applied over the transitional film. The transitional film has a first side adapted to bond to polyolefins and the reinforcement system contains a fiber-reinforced polyurethane system bonded to the second side of the transitional film. A system two polyolefin tubular members joined end-to-end containing two tubular members arranged such that their respective ends are adjacent, thereby defining a circumferential joint, a transitional film applied and bonded to the circumferential joint and at least a portion of the two tubular members, and a reinforcement system applied over the transitional film. The transitional film has a first side adapted to bond to polyolefins and the reinforcement system contains a fiber-reinforced polyurethane or a fiber-reinforced epoxy system bonded to the second side of the transitional film.
