In the petroleum industry, pressure plugging is a key operational step to ensure the efficiency of downhole operations. The manufacturing requirements of a pressure plug are rigorous and require a series of rigorous procedures and standards to ensure the quality and reliability of the plug tool. This article will delve into the requirements of pressure sealing manufacturing, from material selection, process flow to quality control, etc., in order to help readers more comprehensively understand and master the knowledge of this important field.

First, material selection

1. Sealing material: The sealing performance of sealing tools with pressure is directly related to the efficiency of the operation. Therefore, when selecting sealing materials, priority should be given to their high temperature resistance, pressure resistance, corrosion resistance and other characteristics. Commonly used sealing materials include rubber, polyurethane, fluorine rubber, etc., need to make a reasonable choice according to the specific operating conditions and requirements.

2. Structural materials: Structural materials with pressure sealing tools need to have good strength and durability to ensure stable operation in high temperature and high pressure environments. Commonly used structural materials including carbon steel, stainless steel, alloy steel, etc., need to make the appropriate choice according to the working conditions and requirements.

3. Materials: In addition to sealing materials and structural materials, sealing tools with pressure also need some materials to improve their performance and reliability, such as lubricants, sealants, coatings, etc. The selection of these materials should consider their compatibility and stability with other materials to ensure that the overall performance meets the requirements.

Second, the process flow

1. Design phase: The design of the sealing tool with pressure is a key step to ensure its performance and reliability. The design process needs to take into account the working environment, working conditions, sealing requirements and other factors, and reasonably determine the structure, size, material and other parameters of the tool. The design process should follow the relevant standards and specifications to ensure the operability of the tool.

2. Manufacturing process: The process of manufacturing sealing tools with pressure requires strict control of all aspects to ensure the quality and consistency of tools. Advanced processing equipment and technology should be used in production, and processing and assembly should be carried out in strict accordance with the design requirements. Key process links such as welding, drilling, heat treatment, etc., also need to be improved to avoid the introduction of defects and hidden dangers.

3. Testing and acceptance: After the manufacturing is completed, the sealing tools with pressure need to undergo strict testing and acceptance to ensure that they meet the relevant standards and requirements. The test contents include appearance inspection, size measurement, air tightness test, pressure performance test, etc. The test results should meet the design requirements before leaving the factory.

Third, quality control

1. System establishment: In order to ensure the quality stability and reliability of sealing tools with pressure, enterprises should establish a sound quality management system, including quality system documents, operation instructions, testing procedures, etc. The system should clarify the responsibilities and processes of each work to ensure that each process can be effectively controlled.

2. Process control: In the manufacturing process, the process control of each link should be strengthened to discover and correct possible problems in a timely manner. Through the establishment of process card, quality record card and other means to achieve the whole process of production monitoring, to ensure that each product meets the standard requirements.

3. Disposal of defective products: The defective products found should be stopped immediately and analyzed to find out the cause of the problem and take effective measures to improve them. The handling of defective products should be timely and accurate, and the defective products should flow into the market to ensure the quality and reputation of the products.

Conclusion:

The manufacturing requirements of sealing tools with pressure are a comprehensive issue that requires comprehensive consideration and control in terms of material selection, process flow and quality control. To do a good job in every link, we can ensure the quality and reliability of the sealing tool with pressure and ensure the efficiency of the operation. It is hoped that the discussion in this paper can provide some reference and inspiration for readers to better understand and apply the requirements of sealing with pressure.
