What Thai NDT does
Thai NDT Public Company Limited (TNDT, bkk:TNDT) is a Bangkok-headquartered, publicly listed industrial services firm founded on April 21, 1982, providing non-destructive testing (NDT), engineering inspection and certification, and technical development services to enterprise clients primarily in Thailand's oil and gas, petrochemical, power generation, construction, and emerging medical/healthcare sectors. The company operates two core service lines: (1) a comprehensive NDT inspection division offering both conventional methods (Eddy Current, Magnetic Particle, Liquid Penetrant, Radiographic, Ultrasonic, Visual, Leak Testing, ACFM, Thermography) and advanced techniques (Phased Array Ultrasonic Corrosion Mapping, Pipeline AUT, Positive Material Identification, Eddy Current Array, Tank Floor Scanning, Tube Inspection, Intelligent Pigging), and (2) a commercial Electron Beam irradiation service for medical device sterilization, polymer cross-linking, and food irradiation, operated from a USFDA-registered facility in Rayong's Eastern Economic Corridor zone. The business model is professional services-based: project-by-project pricing delivered via direct field sales to enterprise clients, with a six-branch office network covering Thailand's industrial zones plus an Indonesia representative office in Batam. Thai NDT holds extensive regulatory credentials — first-in-Thailand ISO/IEC 17020:2012 Type A inspection body certification, multiple Department of Energy Business licenses (LPG, NGV, fuel oil, boiler, electrical), OAP radiation license, ISO 9001:2015, and USFDA registration for the e-beam facility — which collectively create high regulatory barriers. The company has also diversified into regional energy and mining via joint ventures (LTNDT in Laos, TNDT CM and MKTNDT in Myanmar for coal/power, TNDT Power subsidiary) and operates an in-house SNT-TC-1A training center for NDT personnel development. Key clients include PTTEP, Chevron Thailand, IRPC, PTT Asahi Chemical, CUEL Limited, China Petroleum Pipeline Engineering, and CES Engineering.
