Is it still necessary to install a drain pipe on large storage tanks after adding drain holes?
Thread Content
The water drainage pipe, also known as the discharge pipe, is designed specifically to remove water and impurities from within the tank as well as to eliminate residual oil residues at the bottom of the tank. Looking at the drawings, the large storage tank already has drain holes – why is a discharge pipe still installed? There should be no need for that anymore
It is necessary; in some cases, holes are made directly in the holes. The switch valve and the switch cleaning hole are definitely two different operating conditions. How can you drill a cleaning hole when there is a charge?
Excuse me, does \"making a hole in the hole\" refer to creating an opening in the drain hole for a drainage pipe? Won’t the oil flow out through the drain when there is fluid present?
It’s not necessary; drainage can be handled entirely through the drain holes.
Is there a difference in the height at which the openings are located in the two cases? Perhaps the material discharged from the water outlet can still be reused, while what is expelled through the waste discharge hole is completely unusable.
The sewage pipes and drain pipes should both be installed at the bottom of the storage tank, right? Well, the materials they discharge are those that have settled at the bottom, including water, oil, solid particles, and so on; therefore, what is discharged by the drain valve cannot be recycled. I don’t quite agree with the opinion from the 5th floor. In other words, there is no need to install a drain valve, as the sewage discharge valve serves a comprehensive function. There’s no need to waste the investment, even though the amount is very small.
Those with valves on the drainage holes have the water cut-off process controlled by those valves.
I disagree with what was said on floor 7; if there are valves on the drainage holes, then aren’t there any valves on the waste discharge holes? Draining and filling water are different in terms of operation. Filling water refers to adding water into the tank; it is part of the manufacturing process and is usually carried out at the top of the tank, where water is pumped into the tank. Drainage and sewage discharge are similar; both are located at the bottom of the tank and serve to empty the contents within it.
There seems to be no need to set them separately.
