Pipes are devices used to transport gases, liquids or fluids with solid particles, which are connected by pipes, pipe couplings and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high pressure to the low pressure of the pipeline, and can also be transported by the pressure or gravity of the fluid itself. Pipelines are widely used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

Pipeline Classification

1. Classification by material: metal pipe and non-metal pipe.

2, according to the design pressure classification: vacuum pipeline, low pressure pipeline, high pressure pipeline, ultra high pressure pipeline.

3, according to the transmission temperature classification: low temperature pipeline, normal temperature pipeline, medium temperature and high temperature pipeline.

4. According to the classification of transmission medium: water supply and drainage pipeline, compressed air pipeline, hydrogen pipeline, oxygen pipeline, acetylene pipeline, heating pipeline, gas pipeline, fuel pipeline, toxic fluid pipeline, toxic fluid pipeline, acid and alkali pipeline, boiler pipeline, refrigeration pipeline, purified pure gas pipeline, pure water pipeline.
