Regarding the design pressure for carbon four pressure pipelines
Thread Content
What is the typical design pressure for carbon four pressure pipelines? Why is it said that the pressure rating for pipelines related to carbon four is generally not less than PN25?
Butane belongs to hazardous chemicals; it is flammable and explosive. It is in a liquid state at certain pressures and temperatures, while it is in a gaseous state at room temperature. Under normal conditions, the pressure of butane ranges from 0.1 to 1.0 Mpa. If the purity is not high and the mixture contains components such as propane or higher, the pressure may be even higher. Therefore, even though a pressure of 1.6 Mpa is sufficient for transporting butane, a safety margin is generally added for safety reasons, thereby increasing the pressure rating of the pipeline
It mainly depends on your work stress.
This requirement was specified in the old petrochemical standards (it seems to be SHT3059); it has been removed from the new standards, but many people still follow this requirement and continue to consider the issue of liquefied hydrocarbon gasification
The standard found is HGT 20570.1-1995; it is indeed quite old. It specifies a design value of 1.57 MPa, which is quite consistent
Hello, what exactly is this so-called C4?
