Company founded
1972
Twin Ports Testing 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, materials testing, environmental consulting, industrial hygiene, and industrial chemistry laboratory services. The expansion of Twin Ports Testing through the addition of these services has enabled our involvement in projects from the initial developmental stages through completion.
