Flow-accelerated corrosion and high-temperature pH in closed heating/cooling-medium loops - magnetite stability, wall thinning at bends and welds, wall shear, in-situ vs lab pH, Cr-Mo upgrade screening. USE WHEN: localised thinning or leaks at bends, elbows or welds in carbon-steel tubing; a glycol/water, boiler-feedwater or condensate loop; a WHRU or economiser bundle; amine pH control; or 'is the fluid alkaline enough at temperature?'. Anchors on neqsim.process.corrosion.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NeqSim Flow-Accelerated Corrosion and High-Temperature pH Skill Screening for **flow-accelerated corrosion (FAC)** — dissolution of the protective magnetite film under mass-transfer control — and for the **in-situ pH** that governs it. ## When this skill applies - Localised wall thinning or leaks at **bends, elbows or circumferential welds** in carbon-steel tube bundles, with intact surfaces nearby. - Closed **heating- or cooling-medium loops** (glycol/water or water), boiler-feedwater, condensate, WHRU / economiser / steam-generator tubes. - Operating temperature roughly **90–250 °C**, peaking near 150 °C. - Questions about **pH control** of an amine-buffered loop, or whether measured chemistry is adequate. ## Two mistakes to avoid before anything else **1. Do not judge a hot system by its laboratory pH.** Laboratory pH is measured on a cooled sample, typically at 20–25 °C. Corrosion happens at 150 °C. Two things move, by different amounts: - The amine pK$_a$ falls, so the buffered fluid becomes less alkaline. - **Neutrality itself falls**: neutral water is pH 7.00 at 25 °C but about **pH 5.85 at 150 °C**. …

How to install
mdr add equinor/neqsim/neqsim-flow-accelerated-corrosion@sha256:7ccbf1b24105e024The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
