Why should the branch pipes on the torch main pipe be connected at an angle of 45° to the main pipe, in line with the flow direction of the medium?
Reply 1# zeng46563: Reduce the height difference between pipe layers, minimize the impact force generated when branch pipes are connected to the main pipe, and prevent vibration of the vent pipes
An inclination facilitates the flow of gas into the flare line, preventing backflow； Avoid allowing vent gases to impact the torch line directly ； Entering from above can effectively prevent fluid accumulation ；
The key is to reduce impact and lower resistance
What about inserting it vertically from above, ignoring height considerations?
Shock and pressure resistance. (It’s pleasant to look at too)
I think there are two reasons: First, as everyone should know, the main torch pipe is sloped, leading toward the vent tank. The pressure in the vent main is very low; the liquid flows from the higher points to the vent tank due to its own weight. The branch pipes are connected to the main pipe at an angle of 45° along the flow direction of the fluid, in order to avoid interfering with the natural flow of the condensate. Secondly, many branch pipes originate from safety valves; if they are connected to the main pipe at a 90° angle, there is an issue of reactive force acting on the branch pipes. And a 45° miter joint can **reduce this generating force. Just my personal opinion!
