Sealing with pressure is a common engineering technique, which is mainly used for sealing and sealing of pipeline, container or wellbore facilities. It can effectively prevent the leakage of fluid and ensure the stability of construction or maintenance work. This article will describe the installation process with pressure plug in detail, including preparation, stability measures, material preparation, implementation steps, etc.

1. Preparation

1. Check the working area: ensure that the environment of the working area is stable, eliminate possible dangerous substances, fire sources, etc., and clean up the working area to keep it clean and tidy.

2. Determine the location of the plugging point: According to the engineering requirements and design requirements, determine the specific location and number of pipelines, containers or Wells that need to be blocked.

3. Evaluation of sealing conditions: Evaluate the blocked facilities, including parameters such as size, material, internal pressure, etc., to determine the appropriate sealing method and material selection.

2. Stabilization measures

1. Personnel protection: All personnel involved in the plugging operation must wear personal protective equipment, including stability caps, protective glasses, earplugs, protective gloves, and antistatic clothes.

2. Environmental ventilation: Ensure that the blocked operation area has good ventilation conditions to prevent harmful gas accumulation.

3. Fire and explosion prevention measures: It is prohibited to smoke, use open flame or spark generating equipment in the blocked operation area. Ensure that sealing materials and tools are non-flammable to prevent fire and explosion accidents.

Third, material preparation

1. Sealing material: According to the different sealing points, choose the appropriate sealing material, such as soft sealing ring, hard sealing ring, rubber gasket and so on. Ensure the quality and performance of the material meet the requirements.

2. Plugging tools: Prepare necessary tools, such as wrenches, pipe expansion tools, sealants, and gaskets, to facilitate plugging.

Iv. Implementation steps

1. Disassemble the original seals: Use appropriate tools to disassemble the original seals, and carefully check the status of the sealing surface to ensure that it is clean, smooth, and not obvious.

2. Cleaning and lubrication: clean the sealing surface and sealing materials to ensure that the surface is free of dirt, grease, etc., to improve the sealing effect. Use appropriate amount of lubricant to lubricate the parts that need to be lubricated.

3. Install the sealing material: Select the appropriate sealing material according to the specific requirements of the sealing point, and install it on the sealing surface according to the pressure specification. Pay attention to the position and orientation of the material to ensure a tight connection to the pipe or container.

4. Adjust the sealing material: As required, use tools such as pipe expansion tools or wrenches to properly adjust the position and tightening degree of the sealing material to ensure that the proper pressure is reached between it and the sealing surface, and maintain a good sealing effect.

5. Check the sealing effect: After the sealing is completed, the sealing point is comprehensively checked to ensure that the location of the sealing material is accurate, stable and reliable, and there is no leakage.

6. Stable pressure release: In the case of confirming that the sealing point is stable and reliable, gradually release the pressure to avoid the stability risk caused by sudden pressure release.

5. End your work

1. Clean up the site: After the plugging operation is finished, clean up the working area, remove debris, tools and plugging material residues, and keep the working area clean.

2. Handover record: Fill in the handover record of the plugging operation, including the information about the plugging point, plugging material, and plugging effect, for subsequent reference and management.

Conclusion:

Pressure plug installation is an important and commonly used engineering technique that enables effective plugging and sealing in facilities such as pipelines, containers or Wells. This paper describes the installation process with pressure plug in detail, including preparation work, stability measures, material preparation and implementation steps. When performing a sealing operation with pressure, strictly follow the specifications and pay attention to stability and protective measures to ensure the stability of the construction process and the reliability of the sealing effect.
