On the basis of the 73rd research results of global harmonized low-carbon anti-corrosion standards and cross-border carbon tariff risk early warning, current anti-corrosion maintenance cycles, coating design parameters, material selection schemes and regional risk grading standards are mostly formulated relying on historical meteorological, environmental and industrial monitoring data under steady climate conditions. With the frequent occurrence of global extreme weather such as super typhoons, persistent heavy rainfall, extreme high temperature heatwaves, seasonal salt tide intrusion, continuous drought and regional acid rain pollution caused by climate change, the ambient corrosion intensity of industrial parks is continuously deviating from the historical statistical baseline. Fixed traditional anti-corrosion governance schemes gradually appear maladaptation: coastal industrial areas suffer from prolonged high-concentration salt aerosol erosion leading to premature coating failure; inland industrial zones face frequent acid rain accelerating external atmospheric pitting corrosion; high-temperature heatwave seasons raise the medium operating temperature of heating equipment and significantly accelerate electrochemical corrosion inside pipelines. Static anti-corrosion design and regular maintenance modes can no longer adapt to the dynamic drift of regional corrosion environments under climate change, easily triggering large-scale clustered equipment corrosion leakage accidents and invalid redundant low-carbon anti-corrosion investment. Combined with global climate prediction datasets, regional environmental long-term monitoring big data and the existing BIM-carbon integrated digital governance platform, this paper constructs a climate-driven dynamic corrosion risk prediction model for industrial clusters, establishes a multi-scenario adaptive anti-corrosion parameter dynamic adjustment mechanism, designs a phased governance optimization path combining short-term emergency response, medium-term scheme revision and long-term regional anti-corrosion layout planning, supplements the climate change adaptation governance dimension to the global industrial anti-corrosion ecosystem, realizes the dynamic matching between anti-corrosion technical strategies and evolving environmental corrosion stress, avoids governance failure caused by climate environmental changes, and further enhances the long-term robustness and climate adaptability of the whole lifecycle anti-corrosion governance system.
1. Maladaptation Risks of Traditional Static Anti-Corrosion Governance Under Climate Change Background
Traditional anti-corrosion parameter design and maintenance management rely on historical average environmental data, and four typical adaptive failure risks gradually emerge against the background of frequent global extreme climate events: First, regional atmospheric corrosion baseline drifts upward, leading to premature failure of original anti-corrosion protection schemes. Coastal industrial parks affected by frequent super typhoons and seasonal salt tide backflow have significantly prolonged high-humidity salt fog duration and increased average salt deposition concentration far exceeding the historical design value. The originally formulated conventional thickness weather-resistant anti-corrosion coating will crack, blister and peel several years in advance; the fixed monthly surface de-salting maintenance cycle cannot cope with continuous high corrosion load, forming a large number of external passive film damage hidden points, triggering clustered atmospheric pitting corrosion accidents. In inland industrial agglomerations, frequent regional acid rain events increase the atmospheric deposition of acidic pollutants, accelerating the corrosion of outdoor flange, support and pipeline exposed parts. Second, extreme high-temperature weather aggravates internal medium electrochemical corrosion of heating equipment. Persistent heatwaves push the ambient temperature and circulating process medium temperature beyond the original design working condition range, increasing the electrochemical reaction rate of chloride ions on the titanium passive film. Equipment originally operated under medium-temperature working conditions faces accelerated local pitting initiation risk; fixed descaling and biocide dosing cycles set according to historical average temperature cannot inhibit the rapid reproduction of microorganisms under high-temperature conditions, leading to frequent microbial corrosion and pipeline inner wall scaling blockage. Third, extreme rainfall, flood and drought alternating events cause abrupt changes in the operating environment of industrial circulating water systems. Continuous heavy rainfall leads to the infiltration of external pollutants into centralized cooling water pipelines, resulting in sudden surges in chloride, suspended solids and organic pollutant indicators; drought periods force enterprises to adopt recycled reclaimed water for circulating cooling, further increasing the salinity of the medium. Static water quality early warning thresholds and regular reagent dosing schemes fail to respond to sudden water quality deterioration, inducing widespread under-deposit corrosion inside equipment clusters. Fourth, climate change leads to the regional migration of industrial corrosion risk zones, and the original four-level corrosion risk zoning cannot reflect the actual current corrosion intensity. Traditional regional corrosion risk grading is delineated based on decades ago environmental monitoring data; with the migration of coastal salt tide belts, the expansion of acid rain influence areas and the frequent occurrence of extreme high-temperature zones, some originally divided moderate corrosion risk areas are upgraded to severe or ultra-severe risk areas, while the original high-risk zones have higher corrosion intensity. If enterprises still implement the original maintenance cycle, coating thickness and material selection standards, anti-corrosion protection will be seriously insufficient; conversely, some areas with reduced annual average corrosion intensity face redundant low-carbon anti-corrosion investment and waste of green governance costs.
2. Construction of Climate-Driven Dynamic Corrosion Risk Prediction Model for Industrial Equipment Clusters
Integrate global regional climate scenario prediction datasets, long-term environmental monitoring data, industrial park atmospheric pollutant monitoring records and historical equipment corrosion failure case samples, build a multi-dimensional dynamic corrosion risk prediction framework based on machine learning, and realize short-term extreme weather early warning, medium-term seasonal corrosion intensity prediction and long-term climate evolution trend risk zoning forecast.
2.1 Multi-Source Fusion Input Dataset Construction
Four categories of basic data are accessed to the BIM anti-corrosion collaborative governance platform for standardized cleaning and fusion:
Historical and forecast meteorological data: regional temperature, relative humidity, rainfall frequency, wind direction and wind speed, typhoon track, salt tide intrusion period, acid rain pH value, extreme high-temperature continuous duration under multiple climate change scenarios;
Long-term environmental corrosion monitoring data: atmospheric salt deposition rate, industrial acid gas concentration, soil resistivity, centralized circulating water conventional water quality monitoring indicators, seasonal variation law of each parameter;
Equipment basic attribute data: BIM component material grade, anti-corrosion coating type and thickness, design operating temperature, outdoor exposure location, original risk grade, historical maintenance records and corrosion defect distribution;
Historical failure sample data: time, location, corrosion type, inducement and environmental background parameters of all past equipment leakage and corrosion failure accidents in the industrial cluster, which are used to train the risk prediction model. All datasets are spatially calibrated according to the geographic coordinates of each equipment component and industrial monitoring station, forming spatially matched multi-dimensional feature samples for model training and verification.
2.2 Hierarchical Dynamic Corrosion Risk Prediction Model Framework
The model is divided into three prediction time scales to realize differentiated early warning and governance guidance:
Short-term extreme weather corrosion risk emergency prediction (1–30 days): aiming at typhoons, heatwaves, heavy rainfall, salt tides and other sudden extreme events, predict the peak value and duration of regional corrosion stress, identify high-risk equipment groups such as outdoor exposed pipelines, coastal windward heating units, circulating water connected equipment, output emergency anti-corrosion reinforcement suggestions including temporary surface protective covering, advance circulating water dosing, pre-enhanced leakage inspection frequency.
Medium-term seasonal dynamic corrosion intensity prediction (1–12 months): predict the seasonal variation trend of regional atmospheric and medium corrosion intensity, dynamically adjust the effective anti-corrosion protection residual life of coatings, sealing components and passive films, revise the optimal maintenance cycle of cleaning, de-salting, coating inspection and bolt torque reinspection according to the predicted seasonal corrosion load, avoid insufficient maintenance or redundant maintenance.
Long-term climate evolution corrosion risk zoning prediction (5–30 years): under multiple climate change emission scenarios, simulate the long-term drift trend of regional corrosion baseline, dynamically update the four-level regional corrosion risk zoning map, identify risk upgrading and risk downgrading areas, provide decision basis for equipment renovation, anti-corrosion process upgrading and new project site selection anti-corrosion design parameter formulation. The prediction results are bound to each BIM equipment component, and the risk change trend of each heating equipment can be visually displayed on the three-dimensional model; all prediction logs, parameter input records and model version information are stored in the blockchain traceability system, which can be used as the basis for subsequent anti-corrosion scheme adaptive adjustment and low-carbon governance benefit accounting.
3. Multi-Scenario Adaptive Anti-Corrosion Governance Dynamic Adjustment Mechanism
Form a closed-loop adjustment mechanism of "climate environmental prediction → risk drift identification → anti-corrosion parameter dynamic revision → whole-process implementation constraint → effect feedback model optimization", and realize adaptive optimization from design, material, maintenance, monitoring multiple dimensions.
3.1 Design Parameter Dynamic Adaptive Adjustment Mechanism
For new EPC projects and equipment renovation projects, the BIM platform automatically invokes the latest regional dynamic corrosion risk zoning results to replace the historical static risk grade, intelligently adjust the recommended coating thickness, insulating anti-fretting material specification, pipeline drainage gradient, sealing material aging resistance grade and allowable medium temperature threshold. For areas where the corrosion risk is predicted to be upgraded, the system forcibly pushes high-temperature resistant, high salt-fog resistant modified anti-corrosion coating schemes and high-purity titanium material selection requirements; for risk-declining regions, appropriately optimize the anti-corrosion material specification to avoid redundant carbon emission brought by over-protection, balance safety governance and low-carbon benefit.
3.2 Periodic Maintenance Dynamic Schedule Optimization Mechanism
According to seasonal predicted corrosion intensity, the platform dynamically adjusts the inspection cycle, cleaning frequency, salt cleaning interval and reagent dosage of equipment clusters. During the predicted salt tide and high-temperature seasons, shorten the outdoor equipment surface inspection and de-salting maintenance cycle, increase the sampling frequency of circulating water chloride and microbial indicators, appropriately increase the dosage of green biocides; in low-corrosion dry and cold seasons, extend the maintenance cycle reasonably, reduce the consumption of anti-corrosion chemicals and inert gas, realize the dynamic optimization of low-carbon anti-corrosion benefits under the premise of safety. All revised maintenance plans are automatically synchronized to the enterprise operation and maintenance management module and the national anti-corrosion public service platform, forming standardized executable task lists.
3.3 Environmental Monitoring and Intelligent Early Warning Threshold Adaptive Calibration Mechanism
The regional shared environmental sensing network and equipment on-line monitoring system automatically adjust the early warning threshold of water quality, ambient humidity, salt deposition concentration according to the predicted climate corrosion baseline drift. In high-risk seasons, appropriately lower the abnormal early warning threshold of chloride and organic pollutants in circulating water to realize advance hidden danger disposal; synchronously optimize the multi-factor joint corrosion early warning algorithm parameters of the digital twin platform, improve the identification sensitivity of corrosion precursor signals under high-corrosion environmental load, reduce the missed alarm rate of clustered corrosion risks caused by environmental baseline drift.
4. Phased Climate-Adaptive Anti-Corrosion Governance Optimization Implementation Path

4.3 Long-Term Regional Layout Governance (Multi-Year Climate Evolution Cycle)
Regularly update the regional corrosion risk zoning map every 5 years relying on long-term climate prediction data; for industrial areas where corrosion risk is continuously upgraded, gradually promote high-performance modified anti-corrosion materials, embedded distributed micro-sensing monitoring layout and integrated anti-vibration structural transformation; when planning new industrial parks and equipment projects, avoid predicted future high-risk corrosion zones, adopt climate-adaptive anti-corrosion design parameters from the source; incorporate regional climate corrosion evolution factors into industrial park safety planning and green low-carbon overall layout.
