Cm352 Corrosion Inhibitor Best Jun 2026

During inspections of staking pins, mounting bolt recesses, and other counterweight surfaces, CM352 is applied after cleaning the area with solvents like CM23 (Stoddard solvent) to restore the protective layer. How it Works: The Science of Protection

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | High iron counts despite adequate dosage | Biofilm under-deposit corrosion | Conduct a biocide shock (non-oxidizing) and then re-passivate with CM352. | | Copper pitting | Low azole concentration | Test tolyltriazole levels; supplement with a dedicated copper inhibitor if below 10 ppm. | | White rust on aluminum | pH > 9.5 | Reduce alkalinity via acid feed (sulfuric or CO2). | | Foaming in cooling tower | Overdose >2000 ppm | Reduce feed rate; add a low-silicone antifoam. |

: It is used during inspections to treat surfaces after cleaning away existing corrosion with approved solvents (like Stoddard solvent CM23) and abrasive pads. Identification cm352 corrosion inhibitor

If corrosion is detected, the surface must be cleaned with a solvent (like CM23) and an abrasive pad (CM47) before CM352 is reapplied to restore the protective barrier. How Corrosion Inhibitors Work

CM352 is a mixed-type, adsorption-based corrosion inhibitor primarily designed for (e.g., HCl, H₂SO₄) and sour environments (H₂S-containing brines). It is known for high efficacy on carbon steel , low-alloy steel , and stainless steel at temperatures up to 120°C. Unlike traditional inhibitors (e.g., chromates, nitrites), CM352 is low-toxicity and biodegradable , making it suitable for environmentally sensitive applications such as oilfield acidizing, industrial acid cleaning, and cooling water systems. During inspections of staking pins, mounting bolt recesses,

Implementing CM352 within an asset integrity program offers several distinct operational benefits:

CM352 is extensively used in environments where water is used for cooling or heating, and in process industries. Typical applications include: | | White rust on aluminum | pH > 9

CM352 is a (affects both anodic and cathodic reactions). Its mode of operation involves:

Regulatory and compliance notes CM352 is formulated to comply with common industrial discharge and handling regulations when used per guidelines. Local regulatory requirements vary—confirm permitted discharge concentrations and reporting obligations for your jurisdiction before large-scale release.
