Rugged, Reliable and Accurate Pipeline Integrity Survey Instruments

Welcome to CATHODIC TECHNOLOGY LIMITED. We are a Canadian ISO 9001:2015 registered company with global distribution specializing in corrosion prevention and control equipment. Incorporated in 1980, we began by performing pipeline integrity management surveys, cathodic protection consulting, and other work in the corrosion industry. Being dissatisfied with the available field equipment, we started designing equipment to meet the unique demands of the corrosion industry professional. Our equipment has been engineered & designed from the ground up by corrosion professionals for use by corrosion professionals worldwide. Today, our focus is purely on designing, manufacturing and providing the finest professional grade, contractor tough pipeline integrity survey equipment available on the market.

Pipeline Integrity: Combining Coating Integrity and Cathodic Protection Surveys

Elizabeth Nicholson, Corcon 2014 Corrosion Conference & Expo, Mumbai

Many types of surveys are done to allow the operator to assess the condition of a pipeline.  Two surveys are essential to any pipeline integrity management program, coating integrity and cathodic polarization.  Coating integrity is investigated by generating a pulse on the pipeline, then walking the pipe to locate any voltage gradients in the soil. 

Two Halves of a Whole: Coatings and Cathodic Protection

Elizabeth Nicholson, B.Eng.,Presented at: POLSKI KOMITET ELEKTROCHEMICZNEJ OCHRONY PRZED KOROZJĄ STOWARZYSZENIA ELEKTRYKÓW POLSKICH w WARSZAWIE September 19-21, 2012 in Jurata, Poland

Coatings prevent corrosion by creating a barrier between the structure and the electrolyte.  Cathodic protection works by changing the potential of the structure to interfere with the corrosion process.  Both work together to protect the structure.  Surveys can be done to evaluate the condition of the coating and of the cathodic protection.
