    Overtightening a bolt beyond its recommended bolt load.

    This spec sheet is really helpful. Can you please share its reference. And where are the spec service temps range and bolt material is mentioned?

    Overtightening a bolt beyond its recommended bolt load.

    Thank you for your response. I think the tensile area used here is quite small. the studs diameter is 63.5 from which calculated tensile area should be 3165 mm2. using that min yield load is around 2000 kN.

    Overtightening a bolt beyond its recommended bolt load.

    What would be the consequence of tightening A bolt beyound its recommended bolt load. The recommended operational bolt load is 430 kN and we are planning to tight the bolt via hydraulic bolt tensioner and approximately achieving more than 670 kN bolt load/bolt. 430kN bolt load is recommended by...

    Metal jacketed vs Spiral wound gaskets for Heat Exchangers

    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?

    Leakages in High pressure Urea grade nozzles, lens gaskets.

    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. https://www.meccanicapadana.com/intranet/libretti/libretto123-01-1.pdf

    Leakages in High pressure Urea grade nozzles, lens gaskets.

    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. This link contains information about Drip rings and lens gasket. : https://www.meccanicapadana.com/intranet/libretti/libretto123-01-1.pdf

    Leakages in High pressure Urea grade nozzles, lens gaskets.

    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...

    Leakages in High pressure Urea grade nozzles, lens gaskets.

    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.

    Leakages in High pressure Urea grade nozzles, lens gaskets.

    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?
