The engineering standard with pressure closure is a method commonly used in construction and engineering projects to ensure that pipes, containers, or other equipment do not leak during transportation or use. This method involves the use of pressure and sealing materials to ensure the integrity of the system. The following details the engineering standards for pressure plugging and provides relevant information.

I. Overview

Pressure plugging works are designed to stop the leakage of liquids, gases or other substances from pipelines or equipment by applying pressure and using sealing materials. This technology is widely used in construction, petrochemical, water treatment, energy and other industries. The main purpose of sealing with pressure is to ensure the sealing of equipment and pipelines during transportation, maintenance and use.

2. Standard requirements

1. Equipment and piping must be designed in accordance with relevant industry standards to ensure that they withstand predetermined pressures and temperatures.

2. Prior to a pressure plug, a rigorous assessment and risk analysis must be carried out to ensure that all necessary measures and protective equipment are in place.

3. Sealing materials with pressure must meet the relevant standards and must be fully tested and verified to ensure their performance and reliability.

4. In the construction process, strict operating procedures must be followed, and all operators must be trained and have the appropriate qualifications.

5. Inspection and testing must be carried out in accordance with relevant standards to ensure the effectiveness of sealing with pressure.

6. All construction and inspection records must be recorded in detail and kept properly for future reference.

Third, construction steps

1. Safety preparation: Before any operation with pressure closure, strict stability preparation must be carried out, including determining the boundary of the work area, setting stability warning signs, wearing personal protective equipment, etc.

2. Cleaning and inspection: Clean the surface of the pipe or equipment and check for any damage or defects.

3. Preparation of sealing materials: Select the appropriate sealing materials according to the design requirements and material specifications, and prepare them according to the instructions.

4. Sealing operation: According to the design requirements and operating procedures, the sealing material is applied to the sealing area of the pipeline or equipment, and ensure that the seal is good.

5. Pressure application: Use the appropriate pressure equipment, apply the predetermined pressure to the pipeline or equipment, and observe whether there is any leakage phenomenon.

6. Inspection and testing: Use appropriate inspection and testing methods to evaluate the effectiveness of plugging, and record relevant data and results.

7. Cleanup and recovery: After completion of the pressure plugging operation, clean up the site and carry out the necessary recovery work, including removal of temporary equipment and cleaning of plugging materials.

The above is a brief introduction to the basic requirements and construction steps of the engineering standard with pressure closure. In actual projects, detailed planning and implementation should be carried out according to specific situations and requirements, and relevant industry standards should be strictly followed to ensure construction quality and stability.
