What are pipes? How to classify?

Briefly

Pipeline refers to a device connected with pipes, pipe joints and valves for conveying gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high pressure of the pipeline to the low pressure, and the fluid can also be transported by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

Pipe classification

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

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

3. According to the conveying temperature classification: low temperature pipeline, normal temperature pipeline, medium and high temperature pipeline.

4. Classification by conveying medium: water supply and drainage pipelines, compressed air pipelines, hydrogen pipelines, oxygen pipelines, acetylene pipelines, heat pipelines, gas pipelines, fuel oil pipelines, highly toxic fluid pipelines, toxic fluid pipelines, acid-base pipelines, boiler pipelines, refrigeration Pipelines, purified pure gas pipelines, pure water pipelines.
