Inline inspection of the "unpiggable" in fired-heaters and pipelines
The MERLIN inline inspection tool takes up to 50’000 wall thickness and internal radius readings per metre allowing for identification of tube defects, including: diametric growth; internal and external corrosion; local and general metal loss; pitting and internal fouling.
The bi-directional, single body, neutrally buoyant construction allows the pig to travel with fluid flow for maximum manoeuvrability.
Using the data obtained during the inspection process, Cokebusters can provide Level 1 & 2 FFS/RLA on request.
