petroleum pipeline

Pipeline refers to a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Generally, the fluid flows from the high pressure of the pipeline to the low pressure after being pressurized by the blower, compressor, pump and boiler, and can also be transported by its own pressure or gravity. Pipelines are widely used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.
