Twin Ports Testing (TPT) was founded in 1972 in Duluth, Minnesota, with the initial objective of testing pipeline welds and bends. Since then we have dramatically expanded our capabilities to include comprehensive nondestructive testing and nondestructive evaluation services as well as geotechnical engineering, construction materials testing, environmental consulting, industrial hygiene and industrial chemistry laboratory services. The expansion of TPT through the addition of these services has enabled our involvement in projects from the initial developmental stages through completion.
For over four decades, TPT has provided quality inspection, consulting, and testing services to clients throughout the Upper Midwest, and regions beyond. The accuracy, reliability and cost-effectiveness of our services have earned TPT an excellent reputation. TPT firmly stands behind reliable results. Our reputation for reliability is anchored in state-of-the-art instrumentation, a staff of highly trained professionals, and a stringent system of quality assurance. TPT guarantees rapid response to on-site testing and the shortest possible turnaround time for laboratory evaluation and technical reports.
The innovation of our staff sets TPT apart from our competitors. The entire TPT staff always places the needs of the client first. A well-trained team of engineers, biologists, chemists, geologists, hydrogeologists, industrial hygienists and technicians has been assembled to provide the finest testing and consulting services available. They bring a combined broad base of expertise from industry, construction, public works, the environment, research and education. Our staff is continuously upgrading education and certifications so that we are entirely up-to-date on all procedures and test methods we perform.
Whether a project calls for routine laboratory testing or complex chemical analysis, we understand that solutions are only as good as the data on which they are based. TPT is committed to the reliability of that data. That is our guarantee. The next time you are in need of testing services, please give us a call at 715-392-7114.
