At R and R Corrosion we can carry out and provide the equipment for Signal Attenuation Coating (SAC) Surveys for customers in the oil and gas, water, and construction industries. The Survey will identify and locate any problems within corrosion protection systems such as cathodic protection and film coatings. At R and R we can also provide advice on repairing any protection systems.
Signal Attenuation Coating Surveys involve an AC signal being applied to the pipeline or structure in question. The signal will decrease owing to the resistance of the protective coating as it leaks to earth. At points at which there is a defect in the coating or protection there will be greater signal loss - enabling us to both find the fault and determine the level of coating weakness.
