What NDT Lab does
NDT Lab (legal entity Nondestructive testing OÜ, reg. nr. 14052710) is an Estonian non-destructive testing laboratory headquartered in Tallinn that provides inspection services for welded joints, metal structures, vessels, and pipelines. The company operates seven distinct testing methods under one roof: ultrasonic testing, visual and dimensional inspection, engineering supervision (including ISO 3834, EN 1090, and WPQR support), penetrant control (capillary color defectoscopy), ultrasonic thickness gauging, radiographic X-ray inspection, and magnetic particle testing. All services are delivered within the scope of its ISO/IEC 17025 accreditation issued by the Estonian Accreditation Center (EAK).
The business model is a sales-led B2B professional services offering, with quote-based pricing and on-site delivery at client facilities. Customer acquisition runs through a multilingual website (Estonian, English, Russian, Finnish) equipped with a structured inquiry form; the lab also publishes a formal complaints/claim process underpinning its accreditation compliance. It serves three primary use-case segments — metal construction, pipeline operators, and general manufacturing/mechanical engineering — and operates exclusively within Estonia.
The company is a small founder-operated private limited company (1–10 employees) with no disclosed institutional investors, intellectual property, or management team beyond owners. The only capital event recorded is a €15,000 startup support grant from EAS (Estonian Development Agency) for fixed asset acquisition and innovative service provision. Revenue, ownership structure, and customer roster are not disclosed.
