Doc.79 uniformly regulates the unified compilation standard, content compilation requirement, multi-level approval, formal release, on-site distribution, version synchronous update and invalid document recovery of all anti-corrosion standard documents, solving prominent on-site management problems such as inconsistent document writing specifications, scattered drafting departments, disordered release channels, asynchronous version updates and random self-modification of on-site operation guides, and forming standardized document whole-process closed-loop control from drafting to scrapping. # Chapter 1 General Compilation Basic Standards for All Anti-Corrosion Documents ## 1.1 Unified Naming & Serial Number Specification 1. Fixed serial number rule All anti-corrosion system documents adopt fixed independent serial numbers (33,34,35,38,40,41,45,48,50,53,55,58,59,60,62,64,68,70,71,72,75,79), serial numbers shall not be repeatedly compiled, new supplementary management documents shall apply for new serial numbers sequentially after 79. 2. Standard full document title format Format: [Core Theme] + [Document Type] Example: Hazards of Excess Chloride Ions to Four Kinds of Fermentation Heating Tubes (Doc.45) Example: Full Lifecycle Training & Competency Qualification Specification for Fermentation Heating Tube Anti-Corrosion System (Doc.75) 3. Version coding uniform rule Consistent with Doc.71: Vx.y, x=major revision number, y=minor revision number, initial release version V1.0. ## 1.2 Unified Text & Layout Compilation Format Mandatory Clauses 1. Layout structure unified template Preface → Chapter hierarchical classification (Chapter 1, Chapter 2…) → Sub-section (1.1,1.2…) → Itemized clauses (1/2/3) → Summary/Supplementary Provisions; technical hazard analysis documents support comparative tables, management specification documents support process flowcharts and record template attachments. 2. Terminology unified standard All material names, equipment parameters, risk grading, process indexes shall adopt unified fixed expressions agreed by factory equipment department, prohibited to use self-defined vague terms: - Material uniform name: 316 Stainless Steel / Grade 2 Titanium / PFA Coated Heater / Quartz Glass - Risk unified grading: Red Major Risk / Yellow General Risk / Blue Minor Hidden Danger - Fixed parameter threshold: all pH, chloride, DO, temperature, flow velocity, static time indexes consistent across all documents, no internal contradiction. 3. Numerical unit unification Concentration unit: ppm; flow velocity: m/s; temperature: ℃; time unit: h/min; wall thickness loss: %; all documents use consistent units. 4. Attachment template rule All patrol checklists, test records, accident report ledgers, KPI statistical tables, training forms are uniformly attached to corresponding parent documents, unified naming, fixed format, not allowed separate random printing of modified forms on site. ## 1.3 Cross-Document Content Consistency Compilation Requirement 1. Core index inter-consistency inspection before submission for approval All safe threshold, replacement cycle, start-stop frequency, rinsing standard parameters must be cross-checked against the whole set of existing documents during drafting; any conflict with existing serial documents must be revised uniformly before approval, eliminating contradictory standards. 2. Cross-reference marking rule When mentioning content specified in other serial documents, mark the corresponding document number in parentheses, e.g. "For risk grading standards, refer to Doc.64 Risk Prevention Manual". 3. Unified failure classification definition The definition of heating tube leakage, rupture, coating peeling, pitting corrosion, milky etching fog, frosting damage shall remain identical in all mechanism analysis, accident investigation, inspection audit documents. # Chapter 2 Document Drafting, Review & Multi-Level Approval Closed-Loop Process ## 2.1 Drafting Responsible Division 1. Corrosion mechanism & hazard analysis documents (Doc.33~53): Drafted by factory equipment technical engineer 2. Equipment lifecycle, accident investigation, risk prevention documents (Doc.55/58/64): Drafted by workshop equipment management supervisor 3. Operator SOP, KPI assessment, long-term optimization plan (Doc.59/60/62): Jointly drafted by production supervisor + equipment engineer 4. Supervision audit, archiving traceability, training competency, release management specification (Doc.70/71/75/79): Drafted by factory equipment management department administrator ## 2.2 Four-Step Approval Process (Mandatory Full Sign-Off Before Release) Step1: Professional technical review Drafter submits draft, factory equipment engineer reviews technical rationality, parameter accuracy, cross-document consistency, marks revision opinions and returns for modification if inconsistent. Step2: Workshop on-site applicability review Workshop production director & equipment supervisor jointly audit, verify whether the clauses match actual on-site production equipment and process conditions, adjust operability unreasonable contents. Step3: Functional department joint review Quality management department, safety department conduct joint review: verify GMP compliance, equipment safety risk control, batch quality protection clauses. Step4: Factory-level final approval Factory equipment manager signs for final approval; only after full four-level sign-off can the document enter formal release procedure, any missing signature is deemed invalid draft. ## 2.3 Supplementary & Emergency Supplementary Document Approval Rule When sudden major corrosion accidents, large-scale pipeline reconstruction lead to urgent document revision, launch emergency approval channel: shorten review cycle to 2 working days, but four-level review sign-off procedures cannot be omitted. # Chapter 3 Formal Release, Classification Distribution & On-Site Layout Standard ## 3.1 Unified Release Carrier Management 1. Electronic master file After approval, the drafter uploads the signed official version to factory cloud anti-corrosion document library, sets as master standard electronic file, locks editing authority, only factory equipment department has revision permission. 2. Paper printed official version Uniform printing by factory administrative office, unified cover format printed with document serial number, version number, approval signature scan, anti-counterfeit watermark; self-printed copied documents on site are deemed invalid. ## 3.2 Graded Distribution Object & Quantity Standard 1. Central archive allocation Factory equipment department archive: 2 complete bound sets of all serial documents; workshop equipment management office: 1 full Doc.68 integrated bound volume + single loose-leaf special specifications (Doc.70/71/75/79). 2. On-site post distribution Each shift operation room: 1 set of core frequently-used documents (Doc.59 operator SOP, Doc.64 risk manual); maintenance workshop station: 1 set of maintenance-related specifications (Doc.55, Doc.70, Doc.79). 3.
