Sealing with pressure is a technical measure commonly used in engineering construction, which is used to seal the pipe or hole to prevent the leakage of fluid or gas. It is widely used in various fields, such as petroleum industry, construction engineering, underground engineering and so on. This paper discusses the related problems of sealing with pressure from the perspective of quality and analyzes its quality.

1. Material selection and quality control

In the process of sealing with pressure, material selection and quality control is one of the key factors to ensure the quality of construction. First of all, the selected sealing material should have good sealing and pressure resistance to ensure the reliability of the sealing effect. Secondly, the quality of the material must meet the relevant standards and specifications, and there should be a certificate of conformity. During the construction process, the quality of each batch of purchased materials needs to be tested and operated in strict accordance with the specifications. In addition, it is necessary to pay attention to the storage and custody of materials to avoid moisture, deterioration and other problems.

Second, construction technology and technical requirements

The quality of sealing with pressure is also closely related to the construction process and technical requirements. First of all, the construction plan should be formulated in detail before construction, and the technical disclosure should be carried out to ensure that the construction personnel understand the main points of operation and stable precautions. During the construction process, perform operations according to the specifications, such as cleaning pipes or holes, applying sealing materials, and installing plugging equipment. At the same time, attention should be paid to the control of the construction environment, such as the influence of temperature, humidity and other factors, to ensure the stability of the sealing effect. After the completion of construction, the blocked parts should be inspected and tested to ensure quality.

Third, the quality and training of construction personnel

The quality and training level of construction personnel is also directly related to the sealing with pressure. First of all, construction personnel need to have relevant technical knowledge and skills to understand the sealing process and construction methods. Secondly, the construction personnel should have a good sense of stability and operating norms, and comply with the relevant stability regulations and operating procedures. Before construction, necessary training should be carried out to improve the technical level and comprehensive quality of construction personnel. At the same time, it is necessary to strengthen the supervision and management of construction personnel to ensure that they can operate in accordance with the requirements of the code.

Fourth, quality supervision and acceptance

Quality supervision and acceptance is an important link to ensure the quality of sealing with pressure. In the construction process, technology should be set up for quality supervision, and key nodes in the construction process should be checked and checked. At the same time, it is also necessary to establish quality files to record key data and operational conditions in the construction process for later quality traceability. After the completion of construction, quality acceptance should be carried out to test and evaluate the sealing effect to ensure that the expected quality requirements are met.

Conclusion:

The quality of sealing with pressure is one of the important factors affecting the construction quality of the project, which needs to be controlled comprehensively from the aspects of material selection, construction technology, construction elements and quality supervision. To ensure that these aspects meet the requirements of the code, in order to ensure the reliability of the sealing effect and the stability of the construction quality. Therefore, for the sealing construction with pressure, quality management should be strengthened to improve the construction quality and ensure the stability and reliability of the project.
