Research and Development
Since it’s founding in 1987, TesTex has been focused on the Research and Development of high-end non-destructive testing (NDT) methods, primarily in electromagnetics. Our first R & D project was for Bettis Atomic Labs for the United States Nuclear Navy, where we developed inspection technology for magnetic Heat Exchanger Tubes that could detect and quantify wall thinning as well as pitting without using a secondary inspection method. The Bettis project led to the development of the Remote Field Electromagnetic Technique (RFET), which was the first tubing inspection system to use a portable computer for data display and analysis.
Through the 1990’s, TesTex continued to develop RFET methods with input from various industries, including petroleum refining, chemical, petrochemical, power, pulp, paper and steel. That work led to the most advanced RFET technology available today: the TesTex Multi-Channel RFET. In 1992, TesTex developed the Low Frequency Electromagnetic Technique (LFET) for the inspection of above ground storage tanks (AGSTs). Subsequently, LFET methods have been applied several product lines and settings, including: pipeline and pressure vessel scanning; boiler waterwall, superheater, and reheater scanning; and large diameter pipe inspections from the OD.
The latest development from TesTex is in Crack Detection using what is called Balanced Field Technique to detect surface and sub-surface cracking in magnetic and non-magnetic metals. Current TesTex Hawkeye Crack Detection Systems that are field deployed can detect a crack within 1/8″ of the surface, new prototype sensors are detecting cracks within 3/8″ of the surface.
Whether based upon our own market intelligence or from direct input from industrial customers or trade groups, TesTex continues to conduct leading edge research & development. Our full-time staff of seven (7) researchers have expertise in digital design, mechanical innovation, software programming, system integration, and sensor development.
TesTex always utilizes the latest in digital signal processing (DSP) chips, field programmable gate arrays (FPGA), software algorithms, and automation produce state-of-the-art systems for Electromagnetic NDE.
