What is the pressure control for natural gas pipeline transportation? Our main line is 0.6MPA, and the branches (such as those leading to the boiler) are 0.3MPA.
Gas transmission pipelines can be classified into three types according to their purpose: gathering pipelines, transmission pipelines, and distribution pipelines. ①Gas gathering pipeline: A pipeline that runs from the wellhead equipment in the gas field, through a gas gathering station, to a gas processing plant or an initial compression station; it is primarily used to collect untreated natural gas extracted from the reservoirs. Due to the high pressure in gas wells, the pressure in the gathering pipelines is generally above 100 kilogram-force per square centimeter, with diameters ranging from 50 to 150 millimeters. ②Gas transmission pipelines: These are the pipelines that carry natural gas that has been processed to meet the quality standards required for pipeline transportation, from the gas processing plants or starting compression stations at the source of gas to the distribution centers in major cities, large end-users, or gas storage facilities. They also include pipelines that connect different gas sources together. They constitute the main part of the entire gas transmission system (see gas transmission processes). The diameter of gas transmission pipelines is larger than that of gas collection and distribution pipelines; the largest diameter for gas transmission pipelines at present is 1420 millimeters. Natural gas is transported under pressure using starting compression stations and compression stations along the route; the transmission pressure ranges from 70 to 80 kilogram-force per square centimeter, and the total length of the pipelines can reach several thousand kilometers. ③Distribution pipelines: These are the pipes that run from urban pressure regulation and metering stations to customer branches. They feature low pressure, numerous branches, a dense network, and small diameters. In addition to steel pipes being used extensively, plastic pipes or pipes made of other materials can also be employed for low-pressure distribution pipelines.
2# sdqd800 I would like to ask what the specific pressure range for distribution pipelines is. What is the typical diameter of urban distribution pipelines? I really need these figures; thank you in advance

The main natural gas pipeline has a pressure of around 8 MPa! ………………
Is there any literature reference for this pressure range?
