What are the pressures before and after the natural gas enters the customer’s pressure regulation and metering cabinet outside the plant? Under normal circumstances, which section qualifies as a pressure pipeline?
Before entering the user’s pressure regulation and metering cabinet, there is usually a medium-pressure natural gas pipeline, with a pressure of around 0.4–1.6 MPa； Inside the pressure regulation and metering cabinet, there are usually low-pressure natural gas pipelines, with a pressure of around 0.05–0.1 MPa. Among them, the medium-pressure natural gas pipeline section belongs to pressure pipelines. .
Before entering the user’s pressure regulation and metering cabinet, there is usually a medium-pressure natural gas pipeline, with a pressure of around 0.2–0.4 MPa； Inside the pressure regulation and metering cabinet, there are usually low-pressure natural gas pipelines, with the pressure adjustable as needed, ranging from 0.02 to 0.1 MPa. Among them, the section of medium-pressure natural gas pipeline before pressure regulation belongs to pressure pipelines.
