Atmospheric Corrosion Testing

An atmospheric corrosion survey evaluates whether airborne elements — such as sea salt, corrosive chemical plant discharge, or dust — are contributing to a structure's corrosion. MATCOR technicians inspect the structure, test air and surface deposit samples, and deliver a full report with findings and recommendations.

Are atmospheric conditions contributing to corrosion?

In some cases, corrosion of a structure may be caused by elements in the atmosphere. These airborne chemicals can include:

Salt in the sea air
Corrosive chemicals from the discharge of chemical plants
Airborne dust
Other elements that can induce corrosion and accelerate the rate of corrosion

During a preliminary corrosion analysis of a structure, it may be determined that it is necessary to conduct atmospheric inspection or testing. MATCOR technicians are able to:

Provide a complete inspection of the structure
Test and analyze air samples
Gather, test and analyze sample deposits on the structure or in the structure such as in concrete
Provide a complete report of atmospheric survey results and recommendations

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.
