[0002] Pipeline refers to the pipe that transmits the working fluid in the hydraulic system. Compared with pipeline, pipeline is a reasonably arranged pipeline system. Because of the flexibility of pipeline, pipeline is often used in hydraulic system and other mechanical equipment driven by liquid. Firefighting pipeline refers to the pipeline material used in firefighting, connecting firefighting equipment and equipment, and transporting firefighting water, gas or other media. After long-term use, the surface of the firefighting pipeline is prone to leakage, which causes the fluid inside the pipeline to leak out, and the pipeline needs to be plugged in time.
