The present disclosure provides an assembly including a base structure, a pinhole patch and solder. The base structure includes a body that defines a pinhole. The pinhole patch extends at least partially into and at least partially fills the pinhole. An outer surface of the pinhole patch is disposed adjacent and is mechanically joined to a pinhole surface that defines the pinhole. The solder is disposed over at least a portion of the outer surface of the pinhole patch that bonds the pinhole patch at least to the pinhole surface that defines the pinhole. A subassembly is also disclosed. The subassembly includes a pinhole patch and flux.

A device for fixing components, particularly pipes or tubes, includes two fixing parts with recesses, which can be connected to each other, the parts forming a bushing in the mounted state, the inner contour thereof being designed to receive a pipe or a tube, at least one sacrificial element being arranged for minimizing corrosion, particularly crevice corrosion, in the event of a respectively received component being increasingly consumed with the onset of corrosion and reduction of the service life of the fixation. At least one fixing part includes at least one recess which opens up into the inner contour of the bushing and in which at least one sacrificial element is movably arranged, the sacrificial element being pre-stressed in the direction of the bushing by a spring element.

An isolating flow line spool fitting, particularly for electrical isolation of above-ground steel flow lines or other pipes. Two opposing half segments are electrically separated from each other by non-conductive isolating materials. A first half segment includes a threaded male connection member, while a second half segment includes a mating threaded collar for threadedly connecting the second half segment to the first half segment, and thereby forming a fluid pressure seal.

The methods and systems of lower the grounding potential of an AC electrical grid for protecting a potable water delivery systems from corrosion due to a chemical redox reaction between protective concentration of disinfection chemicals in water and iron, lead and/or copper metal pipes within the potable water delivery system. The methods protect the surface of interactive metals more noble than zinc. These methods are also effective in corrosion protection of the national metallic infrastructure of metals more noble than zinc, such as street signs, lights stands, bridges, and any systems connected to the electrical grid.

The system and method of the present application improve pipeline integrity and may optimize operational efficiencies. Using the data that is generated by cathodic protection and pipeline integrity monitoring devices (e.g. rectifier monitoring), the present application utilizes data analytics techniques, such as artificial intelligence and machine learning algorithms, to improve pipeline integrity operations.

The present invention provides a sacrificial anodic plug for insertion within an irrigation span to provide anodic corrosion protection. According to a preferred embodiment, the anodic plug of the present invention includes a protective cap connected to a securing bushing, and an anodic coupler which extends into the interior of the irrigation span. Preferably, the securing bushing includes non-conductive threads for mating with the threads of a sprinkler outlet and for electrically isolating the anodic coupler from the protective cap. According to further preferred embodiments, the anodic coupler is formed of magnesium and extends down away from the protective cap and terminates in an anodic base. According to a further preferred embodiment, the protective cap may include a wear indicator indicating the amount of anodic material remaining in the central anodic coupler and anodic base.
