A question regarding heat exchangers
Thread Content
The catalytic unit’s fractionation tower top water cooler features a pipe welded beneath the floating head; there is a nut below that pipe, but it seems to have never been used. What does it mean to weld something? Some say it is to prevent stress cracking, but some are welded while others are not. I also saw this thing outside the regenerator; could it be that it leaked and got welded there? Could someone give me some advice? Thank you
I guess it’s used for on-site temperature measurement.
Hehe, that thing is used for waste discharge
The one on the floating head is probably used for pressurizing the heat exchanger, while the one on the regenerator might be an inverse blowing duct
It is more likely to be used for sewage discharge; if pressurization is required, a pressure testing plate can be added to the flange
There should be ones on both the top and bottom, right? Condensate at the lower row, venting at the upper row; pressure testing is also possible
What should be given is all there; it’s just in different forms, but all serve the purpose of providing a sense of relaxation! ! !
Used for temperature measurement; a thermometer is employed to take temperatures, while the nut is used when the tube leaks.
It’s supposed to be used for temperature measurement; of course, it can also be used for draining waste when the condensate drain cannot be opened.
The threaded connections on the heat exchanger are used for pressurization and venting; once the heat exchanger arrives at the site, it will be clear how the construction team carried out the pressurization process. Haven’t seen it on the regenerator.
The exhaust nozzle for pressure suppression is on top; is that the temperature sensor probe? The original poster had better post a photo.
