Why metal jacketed gaskets are used in Heat exchanger's' head covers instead of spiral wound gaskets. What is the advantage of double jacketed gaskets over spiral wound in heat exchangers?
Actually, I am new to this platform. I thought there would be different people in different forums.
Thank you so much for sharing the reference.
@Strong, thank you so much for sharing these references. They are quite helpful.

Hi LittleInch,
Yes, this drip ring acting as a gasket here. It has two sealing surfaces like lens gasket. The drawing and specs of it are mentioned in the link attached.

Dear TugboatEng,
This is a drip ring. That tapping is an integral part of the gasket. I will attach a picture of it below for your info.

Hi LittleInch,
This is a threaded flange on a Urea grade nozzle. Rating is above 2500Lb (special rating for UG). Studs have threads in accordance with ANSI B 1.20.1 NPSM.
No, we are not trying to force this into place. I mean there these spools are properly aligned and have minimal or no stress...
By no tightening margin I meant, the nut won’t further rotate upon striking the spanner. Also the(hexagonal)edges of the nut are getting damaged.
A picture of the assembly is attached.
How to handle a situation in which there is a Urea-Carbamate leakage through a High-pressure Urea grade nozzle and lens gasket.
What to do if the tightening margin is finished after hot tightening?
What should we take care of during installation to avoid such leakages after plant startup?
