Description
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.
