The previous 61 research papers have constructed a full-lifecycle anti-corrosion technical system covering fixed large-scale titanium heating equipment, skid-mounted mobile devices and portable small heating units, with most risk early warning and maintenance management mechanisms designed for single equipment or single workshop independent deployment. In high-corrosion industrial parks, multiple production enterprises share regional environmental conditions including atmospheric salt fog, soil stray current, centralized circulating water supply, industrial waste gas emission and public sewage pipe networks. Abnormal fluctuations in public medium quality, regional environmental pollution accidents and external electromagnetic interference often trigger clustered synchronous corrosion risks for all titanium heating equipment within the park. Isolated equipment-by-equipment monitoring and decentralized enterprise management easily lead to delayed risk discovery, repeated redundant maintenance investment and inconsistent anti-corrosion implementation standards among enterprises. This paper constructs a cross-equipment cluster linked early warning mechanism based on regional shared environmental sensing data, establishes an industrial park collaborative anti-corrosion governance system covering unified monitoring, shared inspection resources, joint emergency disposal, standardized technical training and cross-enterprise failure case sharing, supplements the regional collaborative governance dimension to the original anti-corrosion system, realizes the transformation from decentralized single-equipment risk control to integrated regional overall prevention, further reduces the overall corrosion accident rate and comprehensive operation cost of titanium heating equipment within the industrial park, and perfects the multi-scale governance framework from single equipment, single factory to regional industrial cluster.
1. Clustered Corrosion Risk Evolution Mechanism of Titanium Heating Equipment in Industrial Parks
Regional shared environmental factors are the core inducement of cross-enterprise linked corrosion accidents in industrial parks, and the risk transmission path mainly includes four typical modes: First, centralized circulating water system risk linkage. Most industrial parks adopt unified cooling water supply for multiple enterprises. Once the chloride ion, sulfide, microbial concentration of the public circulating water pipeline exceeds the standard, scaling and biofilm will rapidly spread to all titanium heating equipment connected to the public pipe network, triggering large-scale under-deposit pitting corrosion and microbial-induced corrosion across different workshops and factories. Decentralized independent water quality sampling and delayed parameter adjustment by each enterprise will cause universal passive film damage within the whole park before abnormal risks are discovered. Second, regional atmospheric and soil environmental risk linkage. Coastal chemical parks, electrolysis industrial zones have universal salt aerosol deposition, acid waste gas diffusion and DC stray current leakage. Enterprises close to the same pollution source or power facility will face consistent corrosion stress; if only individual enterprises implement regular salt cleaning and equipotential protection, adjacent factories without corresponding protective measures will rapidly suffer atmospheric pitting and stray current corrosion, and regional extreme weather such as typhoon, heavy fog will simultaneously aggravate the corrosion risk of all outdoor titanium equipment clusters. Third, public pipeline leakage-induced cross-regional risk transmission. When corrosive process medium leaks from public transfer pipelines, leaked pollutants will diffuse through soil, drainage ditches and atmospheric convection, causing secondary corrosion to nearby heating equipment of multiple enterprises. Decentralized emergency disposal will lead to pollution diffusion expansion, and multiple equipment groups will face passive film erosion and medium contamination risks at the same time. Fourth, backward information isolation leads to repeated risk recurrence. Typical corrosion failure cases in one enterprise cannot be timely shared with surrounding factories, resulting in similar misoperation, unreasonable maintenance cycle and mismatched protective material problems repeatedly triggering the same type of leakage accidents in adjacent enterprises, forming clustered repetitive safety losses. In addition, scattered third-party inspection teams of each enterprise have overlapping service areas, resulting in idle inspection resources and high overall regional maintenance costs.
2. Regional Shared Sensing Network Construction and Cross-Cluster Linked Corrosion Early Warning Mechanism
Building a park-level public environmental monitoring platform is the technical foundation for realizing cross-equipment linked risk early warning, which breaks the isolated data barrier of each enterprise's independent monitoring system: Arrange regional fixed environmental sensing nodes at key positions including park circulating water main pipeline, atmospheric pollution monitoring stations, public power corridor soil potential detection points, coastal windward boundary and centralized sewage outlet. The monitoring indicators cover circulating water chloride, pH, dissolved oxygen, total bacteria, atmospheric salt deposition concentration, ambient temperature and humidity, soil stray current potential, toxic gas concentration and other shared risk parameters, and the collected regional public data is uniformly accessed to the park industrial Internet cloud platform. Each enterprise uploads the operating data, equipment maintenance records and local monitoring data of its own titanium heating equipment cluster to the regional platform in compliance with data security authorization rules. The platform builds a two-level linked early warning model: regional overall risk early warning and enterprise equipment cluster refined early warning. When the public circulating water chloride index exceeds the safety threshold, the system automatically pushes blue or yellow early warning to all enterprises connected to the water supply network, reminding each unit to strengthen water quality sampling inspection, appropriately advance descaling and biocide dosing time, and adjust the anti-corrosion maintenance cycle in advance; when regional stray current potential reverses frequently or salt fog concentration surges under extreme weather, the platform issues unified regional orange early warning, requiring all outdoor titanium heating equipment to complete surface de-salting cleaning, inspect grounding and equipotential bonding facilities, and strengthen portable potential detection frequency. Different from single-equipment threshold alarm, the linked early warning system can predict the spread trend of regional corrosion risks, realize forward risk prevention before large-scale equipment failure occurs, rather than passive accident disposal after individual equipment leakage. Classify early warning release levels according to the scope of risk influence: enterprise internal local early warning only acts on the single factory equipment cluster; regional park-level early warning covers all related enterprises within the risk diffusion range, and realizes synchronous information push to equipment managers, maintenance teams and park safety supervision departments through multi-channel terminals. Historical regional environmental abnormal data and clustered corrosion accident cases are incorporated into the big data training set to continuously optimize the linkage early warning threshold, reduce false alarm and missed alarm rates caused by decentralized independent monitoring.
3. Industrial Park Collaborative Anti-Corrosion Governance Institutional Framework and Resource Sharing Mechanism
On the basis of regional linked early warning, establish five major collaborative governance mechanisms to realize the integration of scattered anti-corrosion resources within the park: First, unified park-level anti-corrosion technical standard system. Formulate general anti-corrosion management guidelines suitable for the regional environmental corrosion grade of the industrial park, clarify the unified baseline requirements of public medium regular sampling frequency, outdoor equipment salt cleaning cycle, stray current protection mandatory configuration, qualified cleaning agent and biocide list, prohibited sealing material types and post basic training content. Each enterprise can formulate internal detailed operation specifications on the premise of complying with the park unified bottom-line standard, avoid excessive protective investment or anti-corrosion loopholes caused by inconsistent standard formulation among different enterprises. Second, shared third-party inspection and maintenance resource mechanism. The park uniformly selects qualified anti-corrosion technical service providers to provide centralized regular non-destructive testing, sensor calibration, cathodic protection parameter debugging, chemical cleaning and passivation construction services for all settled enterprises. Establish a shared equipment scheduling pool including handheld thickness gauges, portable potential testers, nitrogen sealing equipment and leakage emergency tools, realize cross-enterprise equipment leasing and shared use during peak maintenance periods, reduce the repeated purchase of high-cost testing equipment by small and medium-sized enterprises, and lower the overall regional anti-corrosion investment cost. Third, joint hierarchical anti-corrosion training and qualification mutual recognition mechanism. The park regularly organizes unified theoretical and practical training for operation and maintenance personnel of all enterprises, compiles regional typical clustered corrosion accident case teaching materials based on local environmental characteristics, and sets up a unified post competency examination question bank. The qualification certificates issued after passing the park assessment are mutually recognized by all settled enterprises, solving the problem of repeated training and certification when personnel flow between different enterprises within the industrial park, and improving the overall professional quality of regional frontline maintenance teams. Fourth, cross-enterprise failure case closed sharing and risk warning mechanism. Build a park confidential corrosion failure case database, each enterprise is required to upload accident investigation reports, root cause analysis conclusions and rectification implementation plans after titanium heating equipment corrosion leakage accidents. The park regularly sorts out typical failure cases and releases regional risk reminders, summarizes common misoperation behaviors and design defects, and guides all enterprises to complete hidden danger self-inspection and specification revision, fundamentally restraining the repeated occurrence of similar clustered corrosion accidents. Fifth, regional joint emergency disposal and pollutant coordinated governance mechanism. Establish a park-level anti-corrosion leakage emergency rescue team and centralized emergency material reserve warehouse. Once cross-enterprise pollution diffusion or large-area equipment leakage risk occurs, uniformly schedule emergency personnel, leakage blocking tools, pollutant absorption materials and waste collection facilities to control the accident diffusion range at the fastest speed. After the accident, coordinate centralized harmless treatment of all leaked hazardous media and contaminated waste, jointly complete regional environmental monitoring and ecological remediation, avoid separate emergency disposal leading to pollution spread and secondary safety accidents.

5. System Complementation and Governance Scale Expansion of the Whole Anti-Corrosion Technical System
This research expands the governance scale of the original 61-set anti-corrosion system from single equipment, single factory to regional industrial cluster, forms a three-tier progressive governance system: micro-scale single equipment full-lifecycle refined protection, mesoscale enterprise internal standardized closed-loop management, macro-scale industrial park regional collaborative linked risk prevention.
