Pressure plugging is a common pipeline repair technique, often used to solve pipeline leakage problems. The technology works by wrapping a special strip around the damaged part of the pipe, pressurizing it to form a sealing layer on the surface of the pipe, thereby preventing gas or liquid leakage. The sealing technology with pressure has the advantages of simple, rapid, economical and hygienic, and is widely used in the maintenance and emergency treatment of various industrial pipelines.

The wear resistance with pressure closure refers to the wear and abrasion ability of the strip used in pipeline maintenance during use. Due to the impact and friction of the fluid in the pipeline and the influence of environmental factors, the wear resistance of the strip is one of the important indicators to measure its quality. In order to ensure the reliability and durability of pressure sealing technology, it is necessary to select strips with high wear resistance and adopt appropriate use and maintenance methods.

In general, there are two main types of tape with pressure sealing: metal tape and composite tape. Metal belts are usually made of stainless steel, aluminum alloy, copper and other materials, which have high strength and rigidity and can withstand greater pressure and wear. However, because the surface of the metal belt is smooth, it is easy to slide and shift, so it is necessary to pay attention to the pressure and fixing method when using. The composite tape is composed of a variety of materials, usually including polyimide, polytetrafluoroethylene, glass fiber, etc., can be designed according to the actual needs of different properties and structures. The composite tape has good wear resistance and corrosion resistance and is suitable for a variety of complex pipeline maintenance environments.

In addition to choosing the right strip, it is also necessary to pay attention to the use and maintenance methods of the strip to ensure its wear resistance. First of all, it is necessary to choose the appropriate strip specification and length according to the actual situation to avoid excessive tensile force and wear of the strip during the pressurization process. Secondly, when pressurizing and fixing the strip, attention should be paid to strength and uniformity to avoid being too tight or too loose. In addition, it is necessary to check and maintain the strip regularly, such as cleaning the pipe surface and checking whether there are cracks, deformation and other abnormal conditions on the strip surface.

In general, as a means of emergency pipeline maintenance, pressure sealing technology has important application value and significance. In the selection and use of strip, it is necessary to pay attention to its wear resistance, take appropriate measures and maintenance methods to ensure its durability and reliability. In the future industrial production, the tape sealing technology will continue to be improved and optimized, and provide more efficient, safe and hygienic solutions for pipeline maintenance.
