Our company, as a professional pressure sealing firm, has been long-term providing engineering services related to pressure sealing, pressure tapping, and pressure sealing. Below, we will delve into a detailed analysis of the working principle of pressure sealing in pipelines:
In leak elimination, pressure-bound sealing does not require fire operations to ensure safety. Pressure-bound sealing refers to the maintenance, emergency repair, auxiliary bypass, replacement, or addition of valves, replacement of pipeline sections, partial pipeline replacement, and internal pipeline fault treatment without stopping the transportation of the medium, reducing pressure, or disrupting the normal operation of the pipeline. This sealing technology reduces economic losses and adverse environmental impacts.
The principle of pressure sealing is based on the sealing mechanism of a liquid medium and solid sealing material under dynamic conditions. The method involves installing equipment at the leakage site, utilizing the chamber formed between the sealing location and the equipment. It uses a high-pressure injection tool to inject sealing adhesive into the chamber, filling the entire chamber space. This balances the pressure of the sealing adhesive and the pressure of the leakage medium, establishing a new sealing structure, blocking the pathways of the leakage holes and the medium's leakage. Moreover, pressure sealing is highly adaptable and has a wide range of applications.
Pressure-sealing technology has been widely applied in people's production and life, serving as a safe, economic, and rapid special technique for pipeline maintenance and repair. It allows for the replacement, relocation, valve replacement, and addition of branches without interrupting the continuous transport of pipeline media. Additionally, it can repair accident pipelines during leaks, restoring the normal operation of the pipeline.
The application of pressure-sealing technology saves on labor and materials without affecting people's daily work and life. It is safe, reliable, pollution-free, and does not interfere with the normal transportation of pipelines, ensuring the safe and environmentally friendly connection of new and old pipelines. Continuous medium transmission involving pressure-sealing technology includes substances like oil, natural gas, water, ethylene, coal gas, medium-grade oil, aviation fuel, etc., which are non-corrosive. It is evident that pressure-sealing technology plays a very important role in our lives.
