Seeking advice on the issue of inward extension during takeover.
Thread Content
Some nozzles for equipment import and export have an inward extension (for liquid ammonia tanks and cryogenic tanks). Some do not have internally extending connectors. Ask under what circumstances the pipe extension is allowed, under what circumstances it is not permitted, and which other equipment allows for pipe extension. What principles govern the inward extension of takeover? What are the regulations regarding the inward extension length, and where can they be found? Thank you.
For the import of ordinary equipment, factors such as overhang, impact, and diffusion need to be taken into consideration. Equipment used for high-pressure and fatigue analysis, for example, generally does not allow for any overhang. Your question is too general; it would take a long time to provide a detailed analysis, and there are no specific regulations regarding this matter. There’s actually not much that needs to be regulated in this area. Why is experience necessary when it comes to chemical engineering machinery? I can only answer you by saying: each case needs to be analyzed on its own. If everything could be explained in just one sentence, then experience would be useless
:dizzy::dizzy: Isn’t that to gain experience from your work?
The best method for equal-area reinforcement is to have effective reinforcement areas on both the inner and outer surfaces; however, due to structural reasons, this may not be possible on the inner surface.
The liquid ammonia tank you mentioned – the long extension inside the low-temperature tank connection is actually the gas phase pipe
