We plan to use fixed pipe as the flexible pipe is prone to leak.
But we do not know how to determine the pipe size, 1″ or 2″ , which is better?
Small pipe is more flexible, but it seem easy to break.
The flow rate of the antifoam in this Delayed Coker plant is 6 m3/h.
It seem 1″ is enough, but we worry that it may break sometime.
