Non‐Destructive Inspection of TCPs Using Pulse‐Echo Ultrasound and X‐Ray Microcomputed Tomography Techniques

open access: yesX-Ray Spectrometry, Volume 55, Issue 3, Page 443-453, May/June 2026.
ABSTRACT Thermoplastic composite pipes (TCPs) have potential applications in offshore oil and gas industries because of their strength, lack of corrosion, and flexibility. Designed for fluid transportation in high‐pressure and high‐temperature environments, manufacturing defects and operational loads can compromise their performance.
