2. Time saving: The clamping connection method is easy and fast to operate, saving tedious preparation work and waiting time, improving construction efficiency, and saving time and cost.
3. Strong seismic performance: The compression connection method utilizes the fastening force on the structure to fix the pipes and joints together, which has high seismic resistance and can adapt to some areas with frequent earthquakes.
4. Good sealing performance: The compression connection method adopts a sealing ring or O-ring to ensure reliable sealing at the connection, prevent leakage problems, and improve the overall sealing performance of the pipeline system.
5. Economical and practical: The compression connection method not only has lower operating costs, but also reduces system operating costs by reducing material and energy consumption, making it an economical and practical connection method.
