Abstract:
An in-depth study of ten nondestructive testing techniques has shown that ultrasonic methods are most suitable for in-specting reinforced plastic composite RPC pipe. Both liquid-coupled and air-coupled ultrasonic systems have been shown to be capable of detecting delaminations, inclusions, and uncured regions in 14 specially prepared sections of 3-inch- diameter fiberglass pipe. Plan view C-scans were recorded using both techniques. The liquid-coupled system showed higher resolu- tion and sensitivity to small-area reflections. Recommended inspection system specifications are listed based upon the per-formance of laboratory equipment used in the program. Author-PL
