Non-Destructive Testing
8 Advanced NDT Techniques for Asset Integrity
NDT is essential for detecting defects and assessing the condition of structures and equipment without causing damage. RIGGING TECH delivers a full range of NDT services — from conventional methods to advanced techniques — supporting lifting equipment inspection, structural integrity assessment, and weld quality control.
Our NDT technicians are certified per ABENDI/SNQC, PCN, or ASNT, with extensive experience in the offshore Oil & Gas environment.
Ultrasonic Corrosion Mapping
C-Scan uses automated ultrasonic scanning to generate 2D thickness and corrosion maps. High-frequency pulses travel through the material and return to the sensor, producing color-coded images that reveal the distribution of wall loss.
Pulsed Eddy Current
PEC/PECA uses electromagnetic induction to detect corrosion and wall loss even through insulation, coatings, or paint. Highly productive for large-area screening without full insulation removal.
Remote Visual Inspection
Videoscopy uses high-resolution cameras on flexible probes to inspect hard-to-reach internal areas. Detects corrosion, cracks, scale buildup, assembly defects, and foreign objects — all without extensive disassembly.
Leak Detection
The Vacuum Box test creates a pressure differential on the surface being inspected. A soap solution is applied, and a transparent box connected to a vacuum pump is placed over the area. Leaks are identified by the formation of bubbles.
Conventional NDT
Conventional NDT encompasses the foundational inspection methods: Ultrasonic Testing (UT), Magnetic Particle Testing (MT), Liquid Penetrant Testing (PT), and Visual Testing (VT). These techniques form the backbone of any integrity program.
Magnetic Flux Leakage
MFL uses powerful magnets to saturate the material with magnetic flux. Where wall loss or corrosion exists, the flux leaks and is detected by sensors. Provides rapid, large-area scanning of tank floors and plates.
Ultrasonic Weld Inspection
Advanced ultrasonic weld inspection using Phased Array (PAUT) and Time-of-Flight Diffraction (TOFD) techniques. Together, they provide comprehensive volumetric weld assessment with superior defect detection.
Positive Material Identification
PMI uses X-Ray Fluorescence (XRF) or Optical Emission Spectrometry (OES) to determine the chemical composition of metals in seconds. Critical for preventing material mix-ups that can lead to premature failure.
