Liquefied natural gas facilities operate at extreme cryogenic temperatures and high pressures where a single weld defect can halt production. Prime Inspections delivers certified NDT services purpose-built for LNG liquefaction, regasification, and export terminals — from storage tanks to loading arms.
Our Level II and Level III technicians hold extensive experience on cryogenic piping, 9% Ni steel, and austenitic stainless systems. We provide documented, code-compliant inspection reports accepted by operators, EPCs, and regulatory agencies worldwide.
Certified Level II and Level III technicians, methods matched to the system and the governing code.
Full NDT inspection of LNG storage tanks including radiographic testing (RT), ultrasonic testing (UT), and magnetic particle testing (MT) on tank shells, nozzles, and foundation welds.
PAUT, AUT, and conventional RT on cryogenic process piping, transfer lines, and regasification systems — ensuring code compliance to ASME B31.3 and API 570 standards.
TOFD, phased array UT, and digital radiography on LNG vaporizers, boil-off gas compressors, and shell-and-tube exchangers for leak-free, high-integrity performance.
MT, PT, and ultrasonic shear-wave inspection on structural steel, pipe supports, and cold-box modules subject to thermal cycling and cryogenic embrittlement risks.
Comprehensive weld inspection during greenfield and brownfield LNG construction — RT, PAUT, MT, PT, and UT on new cryogenic pipelines, tank erection, and facility expansion projects from foundation to commissioning.
Hands-on inspection history with 9% nickel steel, austenitic stainless, and the embrittlement risks unique to cryogenic service.
Based in Houston at the center of the Gulf Coast LNG build-out, with 24/7 response across 11 locations.
Inspection documented to ASME B31.3, API 570, and your project specification — accepted by operators, EPCs, and regulators.
AUT, TOFD, phased array, and digital radiography where conventional film would slow the schedule.
Cryogenic process piping is typically ASME B31.3; in-service piping inspection follows API 570; tanks and vessels follow their construction codes. We inspect and report to the governing code in your specification.
Yes — advanced UT methods (AUT, TOFD, PAUT) and digital radiography support both new construction and in-service integrity programs.
Yes. Our technicians have extensive experience on 9% Ni and austenitic stainless cryogenic systems, where technique selection matters for both detection and schedule.
