Which method for calculating breather valves is correct, SY/T0511.1 or API 2000?
Thread Content
Recently, while performing calculations for the selection of vent valves, I found that the calculation methods specified in the standard SY/T0511.1 for petroleum storage tanks and those in API 2000 are different and even contradictory. Which one is correct?
One is an industry standard, and the other is an international standard
So far, all the calculation sheets for breather valves I have received are based on API2000
SY/T0511.1 and API2000 are two different standards used for calculating the breather valves of oil storage tanks. Their calculation methods may differ, leading to contradictory results. For the selection and calculation of breather valves, it is recommended to follow local regulations as well as relevant industry standards and specifications. If you need accurate calculation results, you can consult professional engineers or relevant institutions for more detailed guidance. .
Several standards such as SY/T0511.1 were merged and revised, and replaced by SY/T 0511-2024
