Waste water treatment plants are subject to corrosion and rust from a variety of causes, one which is Hydrogen Sulphide gas, (H2S.)  Corrosion is an insidious and costly problem that causes just about every metal and metal alloy to fail over time, including metals in electrical and electronic control systems, components, connectors, and switches.

Corrosion is found in almost all industries including wastewater treatment plants, pulp and paper mills, fertilizer plants, and numerous other industries and is not going away. However, with an established Preventative Maintenance Program that includes corrosion prevention it becomes a problem that can be cost effectively dealt with.


Corrosion prevention

One proven and positive way to reduce, if not prevent, corrosion altogether from causing electrical, electronic systems and component failures is by using an ultra-thin film water displacing lubricant material with corrosion inhibiting compound such as SuperCORR A, a proprietary formulation packaged in aerosol cans which uses a non-flammable fast drying carrier solvent. The aerosol is supplied with a flexible tube applicator which allows the protective coating to be applied accurately even in difficult to get to components.

Removal of surface contamination from the metallic contact surfaces on switches and circuit breakers is essential to ensure fault free operation.  The unique SuperCORR A formulation is an inert compound that neither reduces nor increases the electrical conductivity. SuperCORR A also provides long term protection from corrosion and electrical arcing that can lead to shorts and subsequent circuit failures.

An application of SuperCORR A will also prevent corrosion on metals and components in areas where acid or corrosive vapours may accumulate or form such as battery storage compartments and external power connectors.

Testing SuperCORR A in corrosive environments
SuperCORR A (MIL L 871777A Type 1 Grade B lubricant) was subjected to extensive and vigorous Mixed Flowing Gas (MFG) testing at Battelle Laboratories under a U.S. Government contract using ASTM B827 and ASTM B845 Class III MFG testing protocols, which included gases with high corrosion potentials including Hydrogen Sulphide (H2S), Nitrous Oxide (NO2), and Chlorine (Cl2). Full copies of these tests can be made available on request.

ASTM B845 refers to techniques for mixed flowing gas (MFG) tests containing gases that are applied to evaluate devices containing electrical contacts such as slip rings, separable connectors, electromechanical relays or switch contacts. The MFG tests accelerate corrosive degradation processes. Connectors and contacts within closed electronic cabinets may be affected by an environment of different severity than the environment on the outside of these cabinets. In general, indoor environments are different to outdoor environments.

ASTM B827 Provides procedures for conducting environmental tests involving exposures to controlled quantities of corrosive gas mixtures and describes equipment and methods for gas, temperature, and humidity control for tests to be conducted in a reproducible manner. Reproducibility is measured using control coupons whose corrosion films are evaluated by mass gain, coulometry, or by various electron and X-ray beam analysis techniques. Reproducibility can also be measured by in situ corrosion rate monitors using electrical resistance or mass/frequency change methods.


Industrial applications of SuperCORR A

Super CORR A has a proven performance record in protecting electrical components, systems, connectors and electronics and will also prevent the ingress of moisture and other contaminants onto the connector surfaces which initiate corrosion and cause intermittent component failure or a premature degradation of component performance. The Battelle Laboratories studies provided data and related processing information validating the benefits of using SuperCORR A corrosion preventative compound and lubricant to protect the electrical connectors of line replacement units (LRUs) used in military aircraft avionic applications. The results of the laboratory and field-testing activities conducted in these studies confirm that SuperCORR A is an extremely effective coating to protect electronics, electrical components and systems including switches and connectors with no compromise of the integrity of the electrical component/system even in very corrosive environments.

As a result of testing at  Battelle Laboratories and on site testing at a number of private and public company’s SuperCORR A is being used to reduce maintenance and repair costs in a number of different industrial applications including wastewater treatment plants, pulp and paper mills, automotive and heavy equipment industries and in the power production sector oil and gas and renewable energy and in  both the aviation and maritime industries.
