Embedded AC mitigation system
09774105 · 2017-09-26 ·

An embedded Alternating Current (AC) mitigation system reduces or eliminates induced AC currents on pipelines. When a pipeline runs parallel to power lines, the AC current in the power lines induces AC current in the pipeline. Known coatings applied to the pipelines provides electrical insulation and result in a dangerous or destructive buildup of AC voltage in the pipeline. A combination of the pipeline, a dielectric, and a plate, forms a capacitor. The dielectric may be a coating on the pipe, or a dielectric material deposited on the pipeline and under the plate. The capacitor acts as a decoupler by transmitting AC current to the ground while preserving DC current on the pipeline. The embedded AC mitigation system will further act as grounding system and eliminate the need of adding a grounding system.

Quick release thread protector for threads of a pipe
11396968 · 2022-07-26 ·

A thread protector for threads of the pipe has a collet having an inner surface, and outer surface and an end surface, a sleeve cooperative with the collet, and an arm pivotally mounted to the sleeve and having a surface bearing against the and surface of the collet. The collet is adapted to engage the threads of the pipe. The sleeve has a plurality of tapered surfaces thereon. The arm is movable between a first position in which the collet is free of the threads of the pipe and a second position in which the collet moves along the tapered surfaces of the sleeve such that the collet engages the threads of the pipe.

WRAPPABLE PROTECTIVE SLEEVE WITH CLOSURE AND LOCATING FEATURE AND METHODS OF CONSTRUCTION AND USE THEREOF
20210394500 · 2021-12-23 ·

A wrappable protective sleeve for providing protection to at least one elongate member contained therein and methods of construction and use thereof are provided. The sleeve includes a flexible textile wall having opposite inner and outer faces bounded by opposite edges and opposite ends. The opposite edges extend generally parallel to one another between the opposite ends. A pair of adhesive layers is bonded to the inner face, with each of the adhesive layers being spaced from one another. The adhesive layers extend between the opposite ends adjacent the opposite edges. Further, a release paper is releasably adhered to the pair of adhesive layers for subsequent removal and use of the sleeve.
