How to connect the condensate branch pipes and main pipe of a heat exchanger?
Thread Content
As observed on site, the steam branch pipes are connected to the main pipe at a 45-degree angle from the upper part. But the question is: are the condensate branch pipes connected to the main pipe at a 45-degree angle from the upper or lower part, or vertically? Also, which is greater in pressure, the pressure of the condensate branch pipe or that of the main pipe?
Under pressure? Theoretically, it is best to connect to the main pipe at an angle downward, like in the case of a steam trap pipeline, as this reduces resistance and provides shock absorption; however, it affects the strength of the openings.
But it says online that liquids should be introduced from the bottom, while I think it should be from the top as well, for the condensate water from low-pressure steam
