The type standard with pressure closure is a key engineering requirement to ensure the stability and operational stability of the piping system. The following is a detailed description of the standard,

1. Introduction

Pressure plugging is a common pipe repair and test method used to temporarily plug pipes for repair, equipment replacement, or system testing. The purpose of this standard is to ensure the stability and reliability of pressurized closure operations and to minimize any possible risk of accidents and losses.

2. Scope of application

This standard is applicable to all types of pipeline systems, including industrial pipelines, chemical pipelines, oil and gas pipelines, etc. It covers all key aspects of plugging with pressure, including selection of plugging equipment, plugging method, plugging pressure, etc. 3. Definitions and abbreviations

This standard lists common definitions and abbreviations related to pressure plugging to ensure consistency and accuracy in the use of this standard.

4. Equipment and material requirements

4.1 Selection of Plugging equipment

Select the appropriate plugging equipment according to the characteristics and requirements of the pipeline system. The plugging material shall have sufficient strength and corrosion resistance to withstand the pressure and temperature in the pipeline system.

4.2 Plugging Device Testing

Before using the plugging equipment, it should be tested and verified as necessary to ensure that its performance meets the requirements.

5. Plugging methods and procedures

5.1 Preparations for Plugging

Before sealing with pressure, necessary preparations must be carried out on the pipeline system, including cleaning the pipeline, checking the condition of the pipeline and determining the sealing location.

5.2 Sealing Operations

The operation steps of plugging with pressure are described in detail, including the installation of plugging equipment, the filling or hydraulic displacement of plugging device, and the control of plugging pressure.

6. Stabilization measures

6.1 Training for Plugging operators

All personnel involved in a pressure closure operation should receive relevant training on the risks and safety measures of the closure operation.

6.2 Site stability Requirements for plugging

The stability requirements of the operation site with pressure closure are listed in detail, including wearing personal protective equipment, setting up warning signs, maintaining site ventilation, etc.

7. Monitoring and testing

7.1 Monitoring the plugging process

During the plugging process with pressure, periodically monitor the plugging equipment, plugging pressure, and surrounding environment to ensure the stability and effectiveness of the plugging operation.

7.2 Verifying the plugging

After the plugging is complete, the plugging effect should be tested to confirm the effectiveness of the plugging.

8 Records

This standard specifies the documentation and record requirements for plugging operations with pressure, including plugging operation records, plugging equipment test reports, and post-plugging inspection reports.

9. Revision and maintenance of standards

This standard should be regularly revised and maintained to keep track of newer technologies and industry needs.

In SUMMARY:

This standard describes in detail the type standard with pressure plugging, including equipment and material requirements, plugging methods and procedures, stability measures, monitoring and inspection. Its implementation will help ensure the stability and reliability of the operation with pressure closure, and provide guidance and guarantee for the maintenance and testing of the pipeline system.
