Issues such as operating pressure, design pressure and test pressure.
Thread Content
I encountered a strange problem. The operating pressure is 1.8, the design pressure is 6.0, and the test pressure is 7.5. I'm bored. Can anyone explain it?
The design pressure will definitely be higher than the operating pressure, and is a little higher than the maximum pressure that may occur in reality, so it is not surprising that the design pressure is 6.0 and the operating pressure is 1.8. The test pressure is generally 1.25 times the design pressure. In addition, be more rigorous and indicate the pressure unit, which should be MPa.
This is possible because the design pressure is greater than the operating pressure, which should be the design working condition of long-distance oil pipelines in areas with large drops.
The test pressure is generally 1.25 times the design pressure, so the design pressure is 6.0MPa and the test pressure is 6.0* 1.25=7.5MPa.
Sometimes the highest pressure that occurs in the system in a short time is considered, such as the pressure during possible chemical reactions and the pressure during deflagration.
The design pressure must be much higher than the operating pressure. Consider the highest pressure that occurs in the system in a short period of time. The test pressure is generally 1.25 times the design pressure.
The equipment test pressure is 1,25 times the pipeline test pressure and 1,5 times.
Haha, this is the difference between theory and practice
"Pressure Vessel Safety Technical Supervision Regulations" stipulates: The design pressure of the pressure vessel shall not be lower than the maximum operating temperature. Pressure resistance test Pt=ηP/t, hydraulic pressure η=1.25 ； Air pressure η=1.15
Yes, chemical vessel pressure matters. The design pressure must be higher than the operating pressure, otherwise it will be too unsafe. In order to check the manufacturing quality of the designed equipment, a pressure test is required, so the test pressure is 15% or 20% higher than the design pressure, depending on the pressure level of the container.
This is very safe, but the investment may be large.
The container test pressure is generally 1.25 times the design pressure, and the pipeline test pressure is generally 1.5 times the design pressure. But the gap between operating pressure and design pressure is too big
