Originally formed as R-CON International in 1986,Electromechancial Technologies Inc. (d.b.a. ETI) produced client-designed components for the nuclear and aerospace industries and its own product line of specialized and patented high pressure, high temperature connectors (the Arc Connector or R-Con). In 1987, ETI began building ultrasonic in-line pipeline inspection (ILI) tools for hazardous liquid and natural gas pipelines. By 1988 it had added High Resolution Magnetic Flux Leakage (MFL) inspection and it has contributed innovations to the field dating back to that time. ETI sold its pipeline inspection systems in 1992 and did not participate in the field for several years. However, in 2002 the DOT enacted new and more stringent rules and regulations relating to the safe operation of pipelines. ETI took the opportunity to introduce new capabilities consistent with this challenge through the design of a completely new MFL ILI tool. ETI has been a pioneer in the technological advancement of ILI tools. In its MFL tools, it introduced the use of Hall effect sensors, solid state memory and multi-axis sensors. More recently, it has implemented Extra High Resolution (XHR) principles and data analysis. It samples the magnetic leakage field from two to four times as frequently as most other tools. It has strengthened the definition of XHR data to include data reduction parameters consistent with this higher accuracy in field mapping. It has introduced new proprietary technology that provides three dimensional data analysis without the use of multi-axis sensors. In addition to its work in the petroleum industry, ETI produces specialized equipment for the inspection of large diameter water lines. These tools are available for lines from 56" diameter up to 78" diameter and can be used in mortar-lined pipe. These specialized inspection tools are the largest diameter MFL tools in the world.
