The durable process with pressure closure is a common technology in the engineering field, and it has a wide range of applications, including construction, petroleum, gas, chemical and other industries. In this process, through the use of special materials and technical means, the pipes, containers and other equipment are sealed, so as to ensure its reliability in the long-term use of the process.

First, let's look at the concept of pressure plugging. Pressure plugging refers to the application of a certain amount of pressure in the equipment to stop the leakage of liquid, gas or other substances. This sealing method is suitable for various types of pipes and containers, including straight pipe, bend pipe, tee, four-way, etc. It can be used in the process of testing, maintenance and renovation of new equipment.

In the process of sealing with pressure, it is first necessary to select the appropriate sealing material. Common sealing materials include rubber, plastic, metal and so on. These materials have good sealing properties and corrosion resistance, which can effectively stop leaks and air leakage.

Next, we need to prepare for plugging. First, clean and inspect the inside and outside surfaces of the equipment to ensure that there are no impurities and damage. Secondly, according to the size and shape of the equipment, choose the appropriate plugging tools and fixtures. The plugging material is then cut to the appropriate shape and size to match the interface of the device.

Then, the plugging process begins. First, apply a layer of sealant to the interface area of the device to increase the sealing effect. The plugging material is then placed on the interface and secured using a clamp or bolt. When fixing the sealing material, the pressure needs to be gradually increased until the set sealing pressure is reached. At the same time, it is necessary to make appropriate adjustments and checks according to the characteristics and requirements of the equipment.

Once the plugging process is complete, a sealing performance test is required. This can be done by means of pressure testing, vacuum testing, leak testing, etc. The test results shall conform to the design requirements and relevant standards. If the test results are not qualified, the sealing material and process need to be re-checked and adjusted.

During operation, check and maintain the plugging device periodically. This includes monitoring and repairing possible leaks, replacing damaged plugging materials, and performing preventive maintenance measures such as lubrication and cleaning.

In short, a durable process with a pressure plug is a complex and important engineering technique. By selecting the appropriate sealing material and taking the appropriate process measures, the stability and reliability of the equipment can be ensured in the long-term use process. However, in order to achieve the best results, it is necessary to rely on advanced knowledge and experience, and follow the relevant standards and norms.
