Abstract: A system and method for testing and replacing equipment are disclosed. The system may include a first memory module configured to store first characteristics of the first equipment; a second memory module configured to store second characteristics of the second equipment; and a portable reader configured to read the first and second memory modules and to compare the second characteristics with the first characteristics to determine if the second equipment is a suitable replacement for the first equipment. The method may include storing first characteristics of a first equipment on a first memory module; transmitting the first characteristics to a portable reader; measuring second characteristics of a second equipment using a measuring device associated with the portable reader; and comparing, with the portable reader, the second characteristics with the first characteristics to determine if one of the first and second equipment is a suitable replacement for the other equipment.

Abstract: The present disclosure includes systems, apparatus, and methods for monitoring a pipeline network having plural inspection sites. The system comprises a memory module associated with one or more inspection sites, with each memory module storing one or more performance parameters corresponding to the associated inspection site. The system also comprises a measuring device operable to collect performance data of each associated inspection site. The system further comprises a portable reader configured to read the memory module, and in association with the measuring device, to compare the one or more performance parameters with the performance data to validate the performance data while in proximity to the associated inspection site.

Abstract: A welding stud is attachable to a workpiece at a work end portion shaped for enhanced attachment strength with the workpiece. The welding stud has a portion of reduced thickness along a body portion between the work end portion and a retaining collar. The reduced thickness portion is furnished to yield or bend in the event of contact by some other body or piece and preserve the integrity of the attachment weld. The work end portion may also have an enlarged contact face with increased surface area for forming the weld.

Abstract: An access plug flange is provided for inspection ports, for example on high temperature chemical processing vessels or pipes. The plug flange prevents heat loss through an access port formed in an insulative lining covering the vessel or pipe. The plug flange further does not deteriorate or lose its sealing effect despite its location near relatively high temperatures.

Abstract: A marker is provided for attachment to a pipe or other vessel which periodically requires inspection for wall thickness at a specified, defined position. The marker has minimum surface contact with the pipe to protect against moisture accumulation between them. The marker is attached to the pipe or vessel by an attaching cable which also has reduced or minimum surface contact with the pipe. The marker is provided with a lock mechanism and a protective cover to protect the test area from contact by cleaning substances such as sand during sandblasting, as well as coatings or paints applied after cleaning.

Abstract: A capacitive stud welding having an inductive-capacitive welding current supply circuit is provided with a stud and a tunable inductor. The stud is attachable to a workpiece and has an end portion shaped to retain in place on the workpiece at the weld point the flux from the stud to form an optimum weld. The tunable electrical inductor optimizes resonance of the inductive-capacitive welding current supply circuit and the flow of welding current through the stud and workpiece.

Abstract: An apparatus is provided for an access port through an insulative coating or vapor barrier wrap on tubing in cold chemical processes. The apparatus seals against entry of vapors and moisture into the access port which might accumulate there and freeze, causing ice build-up and preventing access of testing probes to the tubing. The apparatus also has an insulative effect against transfer of external ambient heat through its structure to the tubing.

Abstract: An access plug flange and sealing plug are provided for inspection ports on chemical processing vessels. The plug flanges are easily installed, while remaining firmly and securely in place; the sealing plug is also easily removable from the flange for inspection purposes.
