[Special Equipment Safety Management and Standardization]--How to check the next inspection date of pressure pipelines?

Thread Content

The 25th National "Safety Production Month" in 2026. Everyone pays attention to safety, and everyone will investigate and rectify potential risks in an emergency. -------------------------------------------------- Do a good job in special equipment safety management and standardization management to ensure safety [Special Equipment Safety Management and Standardization] Summary post! Welcome to communicate as we continue to update! ! ! https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=5718553( Source: Haichuan Chemical Forum (Huahaichuanliu hcbbs)) Everyone is welcome to participate in exchanges and discussions----------------------------------------------------------------- Consult with peers from supervisory agencies: When we check whether the gas pipelines are within the validity period of the inspection according to the "Routine Supervision and Inspection Items of Special Equipment User Units", some of them can be found in the "Comprehensive Inspection Conclusion Report of Public Pipelines", but some cannot? The next inspection date, which is the boundary point of the qualified period that represents the phased safety status of pressure pipelines, is one of the key points of special equipment safety supervision and inspection. The statutory next inspection date is derived from the inspection report of the inspection and testing agency or the fitness for use evaluation conclusion report. Classification of pressure piping related to inspection. Pressure pipelines are divided into three categories: industrial pipelines, public pipelines, and long-distance pipelines. Public pipelines are divided into two types: gas pipelines (GB1) and thermal pipelines (GB2). Gas pipelines within the scope of special equipment supervision are divided into six levels according to design pressure.: 1. The design pressure of GB1-I grade high-pressure gas pipeline is 2.5＜P≤4.0MPa ； 2. The design pressure of GB1-II grade high-pressure gas pipeline is 1.6＜P≤2.5MPa ； 3.The design pressure of GB1-Ⅲ grade sub-high pressure gas pipeline is 0.8＜P≤1.6MPa ； 4. The design pressure of GB1-IV grade sub-high pressure gas pipeline is 0.4＜P≤0.8MPa ； 5.The design pressure of GB1-V grade medium-pressure gas pipeline is 0.2＜P≤0.4MPa ； 6.The design pressure of GB1-Ⅵ grade medium pressure gas pipeline is 0.1≤P≤0.2MPa ； Check the next inspection date accordingly. The next inspection date for different pressure pipelines is reflected in different reports. 1. The next inspection date of industrial pipelines can be found in the "Industrial Pipeline Periodic Inspection Conclusion Report" ； 2. The next inspection date for GB1-I level, GB1-II level high-pressure gas pipelines, and GB1-III level sub-high-pressure gas pipelines can be found in the "Public Pipeline Fitness for Use Evaluation Conclusion Report" ； 3. GB1-Ⅳ grade sub-high-pressure gas pipelines, GB1-Ⅴ grade medium-pressure gas pipelines, GB1-Ⅵ grade medium-pressure gas pipelines and GB2 thermal pipelines are available in the "Comprehensive Inspection Conclusion Report of Public Pipelines" ； 4. The next inspection date of long-distance pipelines can be found in the "Long-distance (Oil and Gas) Pipeline Fitness for Service Evaluation Conclusion Report".
