Coating Conductance Testing

MATCOR evaluates pipeline coating condition and effectiveness using DCVG/ACVG surveys and Pipeline Current Mapper (PCM) attenuation surveys for underground pipelines, and external corrosion direct assessment (ECDA) for exposed or above-ground pipelines and tanks. Our technicians also recommend repairs, rehabilitation, and coatings to prevent corrosion on new construction.

Pipeline coatings, both above ground and below ground should be evaluated regularly for condition, effectiveness and the potential for pipeline failures.

Evaluating Underground Pipelines

Below ground pipeline coatings are evaluated using indirect inspection techniques such as direct current voltage gradient (DCVG) and alternating current voltage gradient (ACVG) surveys.

A Pipeline Current Mapper or PCM can also be used to perform an AC current attenuation survey to qualitatively rank coating quality and highlight pipeline locations with the most significant coating holidays (defects).

Evaluating Exposed or Above-Ground Pipelines

External corrosion direct assessment (ECDA) inspection techniques are used when the underground pipeline is exposed or for above ground pipelines.

Qualified MATCOR technical personnel are available to perform coating surveys, inspection and evaluation for oil, gas and water pipelines and storage tanks, in addition to recommending pipeline repairs and rehabilitation, and coatings to prevent corrosion for new pipeline or tank construction.

Durammo Deep Anode System

Durammo® is MATCOR’s factory-assembled, ready-to-install deep anode system for cathodic protection of pipelines, wells, and buried infrastructure. Nearly 10,000 systems have logged over 200 million hours, featuring MMO anodes, patented Kynex® connections, and Kynar® cables.

The MITIGATOR

The MITIGATOR® is the industry’s only engineered AC mitigation system to combat the corrosive effects of alternating current (AC) on pipelines, combining performance with greater ease of installation and lower cost. Providing superior performance over bare copper and zinc for AC grounding and mitigation, this system is based on MATCOR’s SPL™-Anode manufacturing technology. It is a packaged grounding system that combines the best of copper grounding with low resistance, corrosion-inhibiting backfill.

AC DC Coupon Test Stations

Where AC corrosion is a threat, monitoring must shift from polarization measurements to current density measurements—and that requires coupon test stations. MATCOR supplies AC/DC coupon test stations with dedicated AC and DC current density coupons, ensuring localized conditions don’t create AC corrosion risk that standard test stations can’t detect.

Cathodic Protection Rectifiers

MATCOR rectifiers come standard with features that are only available as options on some competing rectifiers. Every part of a MATCOR rectifier is covered by our two-year guarantee, and the transformer comes with an industry leading five-year warranty.
