#### Introduction

With the rapid development of the oil, gas and other fluid transportation industries, pressure plugging technology is playing an increasingly important role in maintenance and repair operations. Pressure plugging is a technique for sealing the fluid while the pipe or equipment is still under pressure to allow for repair, maintenance, or replacement of equipment. Although the traditional plugging equipment with pressure can complete the basic plugging task, it is often faced with some technical bottlenecks and operational problems in practical applications. Therefore, it is particularly important to improve the sealing equipment with pressure to improve its efficiency and applicability.

#### Current status of pressure plugging equipment

The existing pressure plugging equipment usually consists of a plugging device, a pneumatic or hydraulic drive system, a control system and a monitoring system. These devices are used in a wide range of industries, including petrochemicals, water supply systems and wastewater treatment. However, as the complexity of the operating environment increases, traditional equipment is exposed to deficiencies in the following aspects:

1. ** Stability problems ** : In high pressure or high temperature environments, the sealing performance of traditional equipment may be insufficient, bringing the risk of leakage.

2. ** Operation complexity ** : Some traditional plugging equipment requires special operation training, which increases the difficulty of operation.

3. Limited scope of application ** : Different types of pipelines and equipment need targeted design of the plugging device, lack of versatility.

4. Insufficient monitoring and feedback ** : The monitoring system of traditional equipment is relatively simple, and the lack of real-time feedback mechanism makes it difficult to make timely judgments on the plugging status.

In view of the above problems, improving the pressure plugging equipment has become an urgent task to be solved.

- ** Automatic control system ** : The development of automatic control system, can automatically adjust the sealing force and sealing state according to the change of the operating environment.

##### 4. Design versatility

In order to increase the versatility of the equipment, the following factors should be considered in the design and design:

** Modular design ** : The modular design enables the equipment to adapt to different calibers and types of pipelines, reducing the cost of equipment replacement and maintenance.

- ** Compatibility design ** : Ensure that the new equipment can be compatible with the existing piping system and equipment, easy to replace and install.

##### 5. Improve the operation process

Optimizing the operation process can effectively improve the stability and efficiency of field operations:

- ** Simplified operation steps ** : By improving the design, the operator can more easily complete the plugging operation and reduce the consumption of human resources.

- ** Provide detailed operating guidelines ** : Provide detailed operating manuals and training for operators to ensure that they can use the equipment stably and effectively in different environments.

#### Case study of equipment improvement

In order to better understand the improvement direction of sealing equipment with pressure, the following will analyze the improvement results in practical applications through several cases.

##### Case 1: Improvement of pressure plugging equipment in a petrochemical company

In the daily maintenance of a petrochemical company, the leakage problem is often encountered with the traditional pressure plugging equipment. After research, they decided to adopt a new high-elastic sealing material and a multi-seal design. After the improvement, the sealing performance of the equipment has been significantly improved, successfully avoiding the risk of leakage in multiple high-pressure operations. In addition, the introduction of an automatic monitoring system allows the operator to monitor the status of the plug in real time, improving the stability of the operation.

##### Case 2: Pipeline maintenance project of a water supply company

In the maintenance project of a city water supply pipeline, the application scope of traditional pressure plugging equipment is limited, so it is necessary to purchase multiple types of equipment. After the improvement, the company adopted a modular design of pressure plugging equipment, reducing equipment procurement costs, but also improve the applicability of the equipment. Through the compatibility of the equipment design, the new equipment can be flexibly used on different types of pipelines, which greatly improves the work efficiency.
