Abstract: A pipe coupling for coupling a first pipe to a second pipe wherein a gap exists between a first pipe end and a second pipe end. The pipe coupling includes a tubular insert configured to fit within the gap and match an inside diameter and outside diameter of the pipes, thereby providing a through-butt joint between the insert and the pipes. The pipe coupling also includes a half-tubular first fitting section and a half-tubular second fitting section, configured to snap-lock and form a tubular shape over the insert, the first pipe end and the second pipe end. In some embodiments, the insert is integral with the fitting sections.

Abstract: A clamp device is for repairing a damaged part of a pipe section. The clamp device has a patch member and a support structure having a clamp body supporting the patch member. The clamp device has a first engagement member configured to engage with a first part of the pipe section and a second engagement member configured to engage with a second part of the pipe section. The clamping device has a first mechanism configured to engage the first engagement member with the first part and compress the patch member at the damaged part, and a second mechanism configured to engage the second engagement member with the second part and induce a compressive force between the first engagement member and the second engagement member.

Abstract: Pipelines in operation specifically the ones operating under high pressures are subject to structural deficiencies therefore, they are susceptible to leakage. The present disclosure relates to a pipeline-leak-containment apparatus comprising an elongate tubular containment wall and at least a first clamp and a second clamp sealingly engaging a section of a pipe to form a sealed interstitial space between the elongate tubular containment wall and the pipe. The tubular containment wall comprises an inner layer, a reinforcement layer and an outer layer. Each clamp comprises an inner clamp, and an outer clamp, wherein at least the inner layer at each end of the elongate tubular containment wall is sealingly sandwiched between the inner clamp and the outer clamp of each clamp. Inner and outer clamps are split clamps that sealingly engage the pipe upon tightening of fastening members.

Abstract: A device and method for sealing a leak in a pipe. The device includes a sealing component that is placed against a pipe outer surface and over the leak. A clamp extending from the sealing component clamps partially around a circumference of the pipe and pulls the sealing component against the pipe. A vent in combination with the sealing member releases leaking gas through or around the sealing component while the sealing component is being secured to the pipe. The vent is then closed after full clamping is completed.

Abstract: A system for repairing irrigation poly-pipe comprises cooperating, user-deployable, inner stabilizer and an outer sealing band that are adhesively attached to prepared ends of the poly pipe to be joined. The stabilizer and sealing band are lightweight, and adapted to be disposed in flat, storage or shipping configurations prior to use. Each end of two flat poly-pipe end segments can be drawn over the stabilizer, abutting tabs at the stabilizer center. Adhesive on stabilizer segments may be exposed by removing tear strips to affix to the pipe ends. An externally applied sealing band has ends that can be manually grasped, for deployment around the pipe ends drawn over the stabilizer, coaxially surrounding the seam formed by the tabs at the juncture of the two pipe ends to seal it and waterproof it.
