Suction header design - construction?
Suction header design - construction?
(OP)
Can anyone share whether or not the branch pipes welded into / onto a larger ID pipe header extend down into that header?
I know that for COMPRESSIBLE flow, this is done with 60-degree angle cuts in the branch pipes extending inside the header; but is that done for INCOMPRESSIBLE flow too?
My concern are vortices and low pressure areas they generate causing the oil to reach vapor pressure. I understand that this is not a concern with gas flow.
My suction pipes and header will be full at all times. My reservoir is elevated above the header and pumps' suctions.

We will design everything from now on using only S.I. units ... except for the pipe diameter. Unk. British engineer

IMHO, there is no reason to extend branch connections into headers based on any process flow requirements.
Furthermore, this type of branch connection would most likely be considered "unique" by the piping code of record and therby require engineering calculations or pressure testing.

Hey "stanier" - I am trying to convince my boss to buy that standard. WOW! $180. Even for the PDF copy! At least if I have to buy it myself I can deduct it on my taxes. Geez!

Note that the return branches do not do this.
From reading, it sounds like they WANT the accelerated velocities; and are also using the ends of the branches to "pick up" or retrieve oil accumulated in the header for the compressors.
