What are the standards for carrying out pipeline blasting and purging?

Pipeline blasting cleaning is a method of pipeline cleaning, and its implementation must comply with the following standards and requirements: 1. GB 50243-2014 \"Code for Construction and Acceptance of Industrial Pipeline Projects\". This standard specifies the requirements for the construction and acceptance of pipeline projects, including the conditions under which pipeline blasting cleaning should be carried out as well as the training required for operators. 2. JB/T 4348-2019 \"Technical Specifications for Industrial Pipeline Blasting and Purging\" – This specification details the technical requirements and operational procedures for pipeline blasting and purging, and it also sets out regulations regarding safety measures, equipment inspection, and maintenance. The specific requirements include: 1. Ensure the safety of personnel and equipment during the blasting and purging process. 2. Determine parameters such as pressure and flow rate for blasting purging based on the conditions inside the pipeline. 3. Conduct equipment inspection and safety assessment prior to operation to ensure normal functioning of the equipment. 4. Operators need to receive professional training and hold relevant certificates. 5. Ensure that the work area is dry and well-ventilated to prevent accidents such as fires and explosions. 6. Conduct necessary recording and reporting, including various parameters and operational details before, during, and after blasting and purging. By meeting the above standards and requirements, the safety and reliability of pipeline blasting and purging operations can be ensured, thereby achieving the desired cleaning effect. .

I’d like to share information on JB/T 4348-2019, the \"Technical Specifications for Blasting and Purging of Industrial Pipelines\"; I can’t find this standard number
