We have extensive in-house inspection and testing facilities, as well as employing external sub-contractors where required. All testing can be witnessed by a customer representative or third party. NDE is used extensively to assess raw materials, in-process inspection of welds, and pre and post-inspection following proof-load testing or heat-treatment. Our NDE Department covers ultrasonic examination, magnetic-particle inspection, dye penetrant inspection and visual examination. Components are often subjected to a site-integrity test to ensure fit-up and compliance prior to delivery; Stephenson Engineering performs all these tests on-site
