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.

Our product offering is lead by the Hexcorder, a GPS synchronized survey instrument capable of performing close interval potential surveys (CIPS), direct current voltage gradient surveys  (DCVG) or combined CIPS & DCVG overland pipeline surveys. This gives a pipeline operator critical data on the condition of their pipe coating by identifying coating defects and the performance of their pipeline cathodic protection system. The data is stored and downloaded as a .csv file, which can be imported into the software of the customer’s choice or easily analysed in Excel. No special software required! The Hexcorder is complimented by our complete range of GPS synchronized current interrupters, capable of interrupting a range of amperage’s.  

Additionally, we offer numerous styles of data loggers. Our Smart Logger is GPS synchronized, allowing the surveyor to record dynamic stray current or telluric interference data on a pipeline survey. The CorrReader is designed to allow non-technical users to obtain valid cathodic protection data from single point surveys, such as test stations or tank farms to satisfy regulatory compliance requirements. All Cath-Tech brand data loggers store GPS time and location for each & every reading to help satisfy regulatory compliance documentation requirements.

Finally, we make a range of GPS synchronized current interrupters, both portable and for retrofit into rectifiers. Cath-Tech was the first to integrate GPS synchronization between the data loggers and current interrupters, allowing a shorter and more accurate interruption cycle and eliminating the need to regularly resynchronize them.

With a comprehensive, industry leading, 2 year warranty the Cath-Tech CP survey instrument family  provide a seamless solution to many of the critical demands of todays pipeline integrity management and  asset protection programs or regulatory compliance concerns.

A Fuzzy Logic Model Designed for Quantitative Risk Analysis based on ECDA Data

Elizabeth Nicholson, Corrosion 2015, Paper 5675

Describes a fuzzy logic model intended for quantitative risk analysis to the integrity of buried pipelines. The proposed approach correlates data from combined CIPS+DCVG coating surveys to the soil resistivity, in order to define an indicator that expresses the corrosion susceptibility at a given coating defect location. Inputs used in the mathematical model include: DCVG defect severity, CIPS pipe-to-soil “OFF” potentials and local soil electrical resistivity
