Must the inlet and outlet valves of atmospheric pressure crude oil floating roof storage tanks be installed on the first flange of the tank body?
Thread Content
Can a short circuit be connected as well? Experts identified this issue and suggested that adding another short circuit would create an additional point of leakage. Are there any standards specifying that valves must be connected to the flange of the tank itself? I need help!
Why do questions need to be connected with short circuits? What is the reason? If there is no necessary reason for it, it is definitely an unsafe behavior. If there are valid reasons, risk identification can be carried out to determine which method poses a higher level of danger.
If the flexible connection is made first and then the valve, two flange connections will be present at the tank outlet, increasing the possibility of leaks. Moreover, in the event of a leak, it cannot be stopped; the material can only be transferred to another tank while the leak persists. If the valve is installed first and then the connection, one flange is reduced, thereby decreasing the likelihood of leaks.
The tank outlet should be directly connected to a valve to reduce the number of leakage points
