A sealing plug system for sealing a hole in a flexible pipe. A shaft extends through a hole in a conduit. A seal couples to the shaft. The seal sealingly engages an interior surface of the conduit. A reaction collar couples to the shaft. A locking system couples to the shaft. The locking system blocks movement of the shaft in a first direction and allows movement of the shaft in a second direction that is opposite the first direction.

A method of repairing an active leak in embodiments of the present invention may include one or more of the following steps: (a) identifying the active leak on a pipe structure, tank or pressure vessel, (b) setting cold spray system settings to repair the pipe structure, (c) administering pressurized gas and metal powder to an active pipe leak, (d) identifying any potential hazards surrounding the active pipe leak, (e) eliminating and/or reducing the potential hazards surround the active pipe leak, (f) inserting a wedge within an active leak pipe hole, (g) ceasing administration of pressurized gas and metal powder to the active pipe leak when it appears sealed, (h) verifying the active pipe leak is sealed, and (i) re-administering the pressurized gas and the metal powder to the active leak is the active leak is not fully sealed.

The present invention provides an adhesive protective film for protecting pipework, the film comprising: a protection layer; a release layer; and an adhesive between the protection and release layer. The release layer comprises a first plurality of uniformly spaced failure initiation locations provided along a first edge of the release layer for initiating tearing of the protective film; and the release layer is at least 50 μm thick.

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 composite system for the reinforcement of physical structures includes a plurality of unidirectional fibers arranged with respective longitudinal axes generally parallel to each other over a substantial portion of a length of each unidirectional fiber. The plurality of unidirectional fibers are non-mechanically connected. A resinous material adheres the plurality of unidirectional fibers to each other such that each one of the plurality of unidirectional fiber is adhered to at least one adjacent one of the plurality of unidirectional fibers along a substantial portion of the length of the adjacent one of the plurality unidirectional fibers.

A reinforced pipe and a method of preparing the reinforced pipe are provided. The reinforced pipe has repair area where a circumferential defect is present in a center section of the repair area. The reinforced pipe comprises a unidirectional fabric circumferentially wrapped around the repair area of the pipe so as to result in multiple layers of the unidirectional fabric around the repair area. The unidirectional fabric is composed of high-performance fibers with at least 90% of the high-performance fibers oriented in the 90 direction, and the unidirectional fabric is wrapped such that the high-performance fibers run in the axial direction. The reinforced pipe further comprises a bidirectional fabric wrapped of over the unidirectional fabric such the at least one layer of bidirectional fabric is wrapped over the unidirectional fabric.
