# **Innovation of Pressure-Resistant Sealing Technology Service Model and Full-Cycle Management Strategy* ## **Introduction** In the fields of high-pressure pipeline operation and maintenance such as petrochemicals and urban gas, the pressure-sealing technology has become an indispensable safety guarantee measure for pipeline renovation and maintenance. With the continuous improvement of industry safety standards and the continuous upgrading of equipment technology, the traditional "just seal and forget" service model has been unable to meet the needs of modern enterprises. This article will systematically analyze the six innovative service models after pressure-sealing operations, deeply discuss the full life cycle management plan, and provide a complete service system construction idea for the industry, covering from emergency repair to intelligent prevention. ## 1. Service System Architecture of Pressure-Resistant Sealing Technology ### 1. Three-Dimensional Model of Service Mode | Service Level | Core Content | Value Realization | |---------|---------|---------|| Basic Services | Implementation of blocking operations, equipment recovery | Ensuring basic construction safety | | Value-added Services | Completeness assessment, data archiving | Extension of pipeline service life | | Intelligent Services | Digital Twinning, Predictive Maintenance | Preventing Major Accidents from Occurring | ### 2. Changes in Modern Service Demands Shift from "isolated blocking tasks" to "comprehensive solutions" From **manual records** to **digital archives** From **passive response** to **active prevention** ## 2. Detailed Explanation of the Comprehensive Six-Phase Innovation Service Model ## 1. Post-Closure Evaluation Services #### (1) Integrity Detection Technology - **Ultrasonic thickness measurement**: Detect the remaining strength of the base material in the sealing area - **Magnetic memory detection**: Identifies areas of stress concentration - **Infrared thermal imaging**: Identifying micro-leakage points in the medium #### (2) Evaluation Report System ```mermaid graph TDA [Sealing Quality Assessment] --> B [Pipeline Remaining Life Prediction] A --> C [Corrosion Protection Layer Status Analysis] A --> D [Suggested Maintenance Period] ### 2. Equipment Hosting Service - **Equipment Sealing and Storage**: Professional temperature-controlled and humidity-controlled storage facility - **Regular maintenance**: The hydraulic system is inspected quarterly. - **Quick Response Mechanism**: Technical support is available within 2 hours. ### 3. Data Asset Services (1) Three-dimensional digital archives The precise coordinates of the blocking point (GPS positioning error < 0.5m) Physical and chemical performance data of the pipe material Video recording of the homework process #### (2) Intelligent Analysis Platform Corrosion rate prediction model Analysis of Stress Change Trend Automatic risk level warning ### 4. Preventive Maintenance Services - **Annual Physical Examination Plan**: Includes 12 key indicator tests - **Cathodic Protection Optimization**: Adjust the protection potential parameters - **Anti-corrosion layer repair**: Use polyolefin heat shrink tape for patching. ## 5.
