One instrument carried by Pacific Rim Marine Surveys Ltd is the Tritex ndt Ultrasonic Thickness Tester. The purpose of this tool is to measure the thickness of various materials including: steel, cast iron, aluminium, copper, brass, pvc, polyethylene to name a few. Material thickness measurement range can vary from 1.5 – 200mm with accuracy to 0.1mm.
This instrument measures the structure with sound anodes and is used in many applications. These can include testing steel or aluminium vessels for hull thickness during pre-purchase or insurance surveys. Quite commonly a vessel will be stated as being built with a particular thickness of material. With a quick meter survey this can be determined to be correct or not! Also the affect of corrosion can be determined on these vessels by comparing meter figures with new-build figures.
This meter is also used to surveys determining repair work to be undertaken. In this way, like material can replace the damaged structure with ease and limited hold up to the job schedule.
