How to determine the diameter of long-distance gas pipelines
Thread Content
A 160 KM gas pipeline needs to be constructed; what diameter should be chosen?
The problem description is unclear: medium, pressure?
You can take a look at HGT20570.6
Please, the original poster, provide a detailed description of parameters such as the medium in the pipeline, operating pressure, and operating environment.
The pipeline is designed to transport 21×108 Nm3 of gas per year. The gas supply comes from a gathering and transmission station in a certain gas field, with a pressure of 2.2–2.5 MPa and a temperature of 32°C. The quality parameters of the gas supplied through pipeline gas supply systems meet the requirements for Class II gas as specified in the standard **Natural Gas** GB17820-2012
Hydraulic calculations are necessary; for such long lengths, software must be used
How can hydraulic calculations be carried out when the pipe diameter hasn’t been determined yet? I’m quite slow to understand; could you explain it in more detail?

The pipeline design specifies a gas delivery volume of 21×108 Nm3/year; the gas supply comes from a gas field gathering and transmission station, with a pressure of 2.2–2.5 MPa and a temperature of 32°C. The gas quality parameters for the pipeline gas supply project meet the requirements of Class II gas standards specified in the standard \"Natural Gas\" GB17820-2012. The pipeline length is 160 KM, with a pressure of 5.0 MPa at the starting station and 2.5 MPa at the ending station
First, preset the pipe diameter, then make adjustments after calculations; after a few attempts, the most appropriate pipe diameter can be determined.
