Resilient Industrial Anti-Corrosion Governance System Construction for Titanium Heating Equipment Under Compound Extreme Disasters and Cascading Risk Chain Interruption Scenarios

Based on the 74th research achievement of climate change-oriented dynamic corrosion risk prediction and adaptive anti-corrosion optimization mechanism, most existing governance frameworks focus on single-type extreme weather and independent equipment risk response, lacking systematic research on compound extreme disasters such as typhoon plus heavy rainfall, heatwave plus power grid collapse, acid rain plus industrial safety leakage, drought plus circulating water system failure. Once multiple disasters occur simultaneously, it is easy to trigger cascading risk chain interruption: regional environmental monitoring networks collapse, centralized circulating water supply fails, factory power supply is cut off, on-site anti-corrosion maintenance personnel cannot arrive, emergency spare parts and green anti-corrosion reagents are out of stock, BIM cloud and digital twin monitoring platforms cannot operate normally. Traditional anti-corrosion emergency plans only aim at single accident disposal, and are difficult to cope with the simultaneous failure of multiple governance links, which will lead to large-scale clustered corrosion failure of titanium heating equipment and long-term industrial production shutdown losses. Combined with compound disaster cascading risk evolution rules, this paper constructs a multi-layer resilient anti-corrosion governance system including distributed redundant monitoring architecture, decentralized emergency resource reserve network, offline-localized anti-corrosion operation backup mechanism, cascading risk chain early warning and segmented isolation disposal strategy, supplements the disaster resilience governance dimension for the existing climate-adaptive global anti-corrosion ecosystem, realizes the continuous effective operation of anti-corrosion risk prevention and control functions under partial infrastructure failure, avoids the overall collapse of the whole governance system under compound extreme disasters, and significantly improves the anti-interference ability and emergency survivability of the full-lifecycle anti-corrosion governance system.

1. Vulnerability of Traditional Centralized Anti-Corrosion Governance Under Compound Extreme Disasters

The current anti-corrosion governance system relies highly on centralized cloud platforms, regional unified water supply, municipal power grids, centralized environmental sensing networks and cross-regional logistics support. In compound disaster scenarios, five typical cascading vulnerabilities are fully exposed: First, centralized digital governance architecture faces single-point collapse risk. BIM collaborative cloud platform, digital twin early warning system and national anti-corrosion public service platform rely on regional backbone power and optical fiber communication. Under typhoon, flood and geological disasters, power outages and communication interruptions will lead to the paralysis of remote real-time monitoring, equipment risk visualization, maintenance task automatic scheduling and cross-enterprise linkage early warning functions. Operation and maintenance personnel cannot obtain high-risk corrosion point distribution, historical equipment damage records and standardized emergency anti-corrosion operation guidelines remotely, and can only rely on limited paper archives and personal experience to deal with accidents, greatly increasing the probability of misoperation-induced corrosion leakage. Second, regional centralized infrastructure interruption triggers chain-type anti-corrosion protection failure. Most industrial parks adopt unified centralized circulating cooling water, public nitrogen supply, centralized hazardous waste treatment and third-party unified inspection service mode. Once the public pipeline network is damaged by floods or strong winds, circulating water quality is out of control, inert gas supply is cut off, waste liquid cannot be treated harmlessly, and third-party service teams are blocked by traffic. A single infrastructure failure will quickly spread to all connected titanium heating equipment clusters, resulting in out-of-control medium corrosion, inability to implement sealed anti-corrosion protection, illegal discharge of waste anti-corrosion liquid and clustered safety hidden dangers. Third, emergency resources are centrally stored, prone to regional supply shortage under large-scale disasters. Anti-corrosion emergency spare parts, green cleaning agents, anti-salt-fog temporary protective materials, leakage blocking tools are mostly stored in a single central warehouse of the industrial park. When compound disasters cause road closure, regional logistics interruption and multiple enterprises simultaneously face anti-corrosion emergency demands, central inventory cannot meet the sudden peak demand, leading to delayed reinforcement protection and emergency repair, making temporary environmental corrosion damage evolve into permanent equipment penetration failure. Fourth, the existing emergency disposal plan is oriented to single risk, lacking cascading risk isolation and segmented response mechanism. Traditional emergency schemes only formulate disposal processes for single accidents such as equipment leakage or salt fog corrosion, without sorting out the risk transmission path of "power outage → monitoring failure → water quality deterioration → microbial corrosion → pipeline leakage → environmental pollution". Once multiple risks occur in series, enterprises cannot quickly cut off the risk transmission link, resulting in the continuous expansion of accident scope and cross-enterprise clustered disaster losses. Fifth, the lack of offline localized backup anti-corrosion operation specification and parameter archive mechanism. All anti-corrosion design thresholds, maintenance cycle standards, material compatibility requirements and emergency construction processes are stored in the cloud system. After communication and power interruption, there is no localized encrypted offline archive available for quick query, temporary anti-corrosion adjustment parameters can only be estimated empirically, which is easy to cause mismatched reagent selection, non-compliant fastening operation and improper passive film repair, leading to secondary damage to equipment.

2. Overall Architecture of Resilient Anti-Corrosion Governance System Under Compound Disasters

Adopt the technical architecture of "edge distributed redundant monitoring + multi-node decentralized emergency resource layout + localized offline data backup + cascading risk chain hierarchical isolation + multi-scenario compound disaster emergency pre-plan", build a five-tier resilient protection system to realize the degradation and orderly operation of anti-corrosion governance functions when part of the infrastructure fails, and avoid overall system collapse.

2.1 Edge Distributed Redundant Monitoring and Offline Localized Data Backup Module

Deploy edge computing gateway nodes in each factory area of the industrial park, breaking the original centralized cloud single-node operation mode: all key anti-corrosion monitoring data, BIM equipment attribute parameters, maintenance specification libraries, emergency operation manuals are synchronously encrypted and backed up to the local edge server. When external optical fiber and power supply are interrupted, the edge node can independently complete local equipment corrosion risk threshold early warning, historical defect record query, standardized emergency maintenance scheme push and equipment high-risk point offline positioning without relying on the remote cloud. Key monitoring points such as circulating water quality, ambient salt deposition, equipment operating temperature adopt dual power supply design of municipal power plus emergency standby generator; core sensing devices are equipped with independent solar power supply modules. After regional power grid collapse, key anti-corrosion risk monitoring can still maintain continuous data collection and local early warning, avoiding the loss of disaster process corrosion evolution data and the blind spot of risk monitoring. All offline backup data adopt tamper-proof encryption storage, and can be automatically synchronized to the cloud platform for supplementary filing after communication and power supply are restored, ensuring the integrity of the whole-lifecycle anti-corrosion traceability data.

2.2 Decentralized Multi-Node Emergency Anti-Corrosion Resource Reserve Network Layout

Change the single central warehouse centralized storage mode, construct a hierarchical distributed emergency resource reserve system of "park regional central reservoir + enterprise factory-level standby depot + key high-risk equipment on-site portable emergency cabinet":

Park central reserve warehouse: store large quantities of anti-corrosion coating raw materials, large-scale leakage blocking equipment, bulk green cleaning agents and emergency nitrogen supply equipment, responsible for cross-factory resource scheduling after single-node inventory is exhausted;

Each enterprise sets up an independent factory-level emergency depot, equipped with conventional sealing gaskets, portable flaw detection instruments, local passive film repair materials, temporary rain and salt prevention protective cloth, to meet the initial emergency disposal demand within 72 hours of disaster occurrence;

All outdoor high-risk titanium heating equipment clusters are equipped with on-site portable emergency cabinets, storing hand-held parameter detection instruments, emergency quick sealing accessories and simplified anti-corrosion operation guide cards, realizing the fastest on-site risk disposal without cross-area resource scheduling. Build a regional emergency resource dynamic scheduling platform based on edge nodes, real-time display the inventory surplus of each reserve node, realize nearby resource allocation under traffic interruption conditions, effectively solve the problem of emergency material shortage caused by regional logistics paralysis under compound disasters. Meanwhile, establish a cross-enterprise emergency material mutual aid and post-disaster compensation mechanism to guarantee the standardized reuse and replenishment of reserved anti-corrosion materials.

2.3 Cascading Corrosion Risk Chain Identification, Segmented Isolation and Hierarchical Early Warning Mechanism

Sort out six typical compound disaster cascading risk chains: ① Typhoon + flood → communication power interruption → monitoring failure → circulating water pollution → under-deposit corrosion → equipment leakage → regional environmental pollution ② Heatwave + power grid collapse → forced equipment shutdown → medium retention in pipeline → high-temperature microbial reproduction → pipeline scaling and pitting corrosion ③ Acid rain + industrial leakage accident → atmospheric corrosive pollutant overflow → outdoor equipment passive film widespread damage → clustered atmospheric corrosion failure Establish a three-level cascading risk early warning and isolation rule:

Level 1 (Source Early Warning): After the meteorological department releases compound disaster forecast, the edge platform locks all high-risk equipment groups, pushes pre-disaster anti-corrosion reinforcement tasks such as pipeline emptying, temporary protective covering and circulating water pre-dosing;

Level 2 (Transmission Link Isolation): Once a single infrastructure failure is detected, automatically trigger isolation measures: close the public circulating water branch valve of the affected factory, cut off the shared nitrogen supply pipeline of the disaster area, lock the maintenance access permission of fault area equipment, prevent risk from spreading to adjacent equipment and enterprises;

Level 3 (Terminal Accident Emergency Disposal): For equipment that has suffered corrosion damage, call the offline emergency disposal specification library to implement standardized local repair, and upload all disposal records to the local edge node for subsequent cloud synchronization filing.

2.4 Multi-Scenario Compound Disaster-Oriented Anti-Corrosion Emergency Pre-Planning System

Form standardized emergency response manuals for each typical compound disaster scenario, which are embedded into the offline edge backup database in both text and video forms, including pre-disaster reinforcement scheme, in-disaster segmented risk isolation operation steps, post-disaster equipment anti-corrosion damage comprehensive inspection method, passive film standardized repair process, waste anti-corrosion hazardous liquid temporary sealed storage specification. Set up hierarchical emergency responsibility authorization under disaster conditions: on-site operation and maintenance personnel have the authority to implement first-level emergency isolation and local anti-corrosion repair; enterprise safety management personnel are responsible for cross-node emergency resource scheduling and regional risk coordination disposal; park management department undertakes cross-enterprise accident joint disposal and external regulatory information reporting. Regularly organize compound disaster emergency drills, continuously optimize the emergency plan and update the offline specification library according to drill defects, and incorporate the emergency standard implementation effect into the enterprise industrial credit evaluation of the national anti-corrosion public service platform.

3. Four-Stage Resilient Closed-Loop Governance Implementation Mechanism for Compound Disasters

3.1 Pre-Disaster Resilience Preparation Stage

Complete edge distributed redundant deployment, offline anti-corrosion archive full backup and hierarchical emergency material reserve layout; dynamically optimize regional corrosion risk zoning and equipment high-risk point distribution relying on climate prediction data; organize compound disaster anti-corrosion emergency training and drill, clarify multi-subject responsibility division and resource mutual aid rules.

3.2 Disaster Early Warning & Pre-Emptive Reinforcement Stage

After receiving the compound disaster forecast cascading risk early warning, finish pipeline residual medium emptying, outdoor equipment temporary anti-corrosion protection, circulating water pre-dosing, emergency generator inspection and standby material inventory verification in advance, cut off non-essential public pipeline connections of high-risk equipment to narrow the potential risk transmission scope.

3.3 In-Disaster Degraded Operation & Segmented Risk Isolation Stage

Under the condition of cloud and centralized infrastructure failure, rely on edge offline system to complete local risk monitoring, emergency scheme query and on-site standardized disposal; implement segmented valve isolation for public facilities to block cascading risk transmission; realize nearby scheduling of decentralized emergency materials to ensure the basic anti-corrosion protection function of key equipment.

3.4 Post-Disaster System Recovery, Damage Assessment & Resilience Optimization Stage

After the disaster subsides, synchronize edge local disaster data to the national anti-corrosion cloud platform, carry out comprehensive anti-corrosion damage identification of equipment clusters, count the effectiveness of emergency resilience measures, summarize the vulnerability links exposed in the disaster process, optimize the redundant monitoring layout, emergency reserve node distribution and emergency pre-plan clauses, realize the iterative upgrading of the resilient governance system, and form a closed-loop of "preparation-warning-disposal-optimization".

4. Connection Between Resilient Governance System and the Existing Global Anti-Corrosion Ecosystem

First, the edge offline backup data is completely consistent with the BIM anti-corrosion parametric model, whole-chain traceability archive and dynamic carbon accounting data of the original system, ensuring the consistency of anti-corrosion judgment standards, maintenance parameters and carbon emission statistical calibers before and after the disaster, avoiding data distortion caused by emergency empirical operation. Second, the post-disaster equipment corrosion damage assessment results will be fed back to the climate dynamic risk prediction model, revise the regional environmental corrosion intensity baseline under compound disaster scenarios, further improve the accuracy of long-term climate adaptive anti-corrosion parameter optimization. Third, the enterprise's resilient governance construction investment, emergency drill implementation records and disaster risk avoidance benefits are incorporated into the enterprise green credit evaluation system, which can be used as preferential conditions for applying for industrial safety transformation subsidies, low-carbon policy loans and green factory certification. Fourth, typical compound disaster resilient anti-corrosion disposal cases are desensitized and shared on the national public service platform, forming a national industrial disaster anti-corrosion emergency standard library, realizing the nationwide replication and promotion of resilient governance experience.
