The re-application interval is linked to the propeller's regular lubrication schedule. Owners and maintenance personnel are advised to reapply the corrosion inhibitor at regularly scheduled intervals, similar to the lubrication interval specified in the applicable propeller owner's manual. This integrated approach ensures that whenever the propeller is being serviced, the protective coating on the counterweights is also inspected and renewed, thereby maintaining a continuous shield against corrosion.
A 30-story office building in Chicago had a 25-year-old chilled water loop. Every spring, they needed to re-pipe sections due to "pinhole elbow syndrome." They switched to CM352 in 2019. After two years, a borescope inspection showed the inside of the steel pipes looked cast-iron grey —passivated, not pitted. Estimated annual repair savings: $18,000.
Introduction CM352 is a next-generation corrosion inhibitor formulated for demanding industrial environments where metal longevity, process reliability, and low environmental impact are critical. Designed as a multifunctional additive, CM352 delivers robust metal protection across a wide range of aqueous and semi-aqueous systems, reduces operational downtime, and integrates easily into existing treatment programs. cm352 corrosion inhibitor
While primarily optimized for closed loops, variations of CM352 are utilized in open recirculating systems to combat the high oxygenation and evaporation rates that accelerate rust. Power Generation and Manufacturing
CM352 corrosion inhibitor is a specialized compound best known for its role in aerospace maintenance, specifically for Hartzell Propeller systems. The primary function of is to prevent corrosion on bolt-on, steel counterweights found in various propeller models. The re-application interval is linked to the propeller's
Proper application of CM352 is crucial for its effectiveness. The process is detailed and must be followed precisely to ensure comprehensive protection. Here is a summary of the standard application procedure:
Deploying a high-performance formulation like CM352 shields vital infrastructure, extends asset lifespans, and optimizes operational efficiency. What is CM352 Corrosion Inhibitor? A 30-story office building in Chicago had a
CM352 has been commercially available since 2018 (developed by , licensed globally). Current R&D focuses on:
According to Hartzell Service Letter HC-SL-61-364 , steel counterweights are pre-coated with CM352 during the factory assembly process. Because these weights control blade pitch angle, surface rust can alter their balance or cause stress-corrosion cracking over time. 2. Recess and Pin Maintenance
). CM352 is injected into these streams to prevent "sweet" ( CO2cap C cap O sub 2 ) and "sour" ( H2Scap H sub 2 cap S
Unscheduled shutdowns due to pipe bursts or boiler failures are incredibly costly. CM352 minimizes iron fouling and sediment accumulation, reducing the frequency of mechanical cleanings, filter replacements, and emergency repairs. 4. Multi-Metal Compatibility
