Advice / Inspections





In 2015 three technicians specialized in destructive and non destructive testing decided to become indipendent and founded the laboratory MEGA-LAB. The great entrepreneurial spirit and professional skills of the owners allowed to obtain in a very short time the ISO 9001 certification and ISO 17025 accreditation.
During the years, more and more customers appreciate the services offered by our laboratory, customers belonging not only to the Oil and Gas market, but also subsea, nuclear and power.
Investments in state-of-the-art equipment, personnel training and machining tools allow not only to perform tests and examinations in the best way, but also with the maximum efficiency and production capacity, thus ensuring reduced waiting times for test execution.
