Thank you jrmichler

Hi everyone, What should be the considerations to choose the proper hose (max working press) installed at outlet air pressure vessels (11 bar) for industrial purposes? Please remark source\link. Also, I've found a table which lists the max sys operating press for 4 different fluids (fuel, oil...

Thank you for the information.

Hi everyone, In purpose to estimate the corrosion degredation in pressure vessels it is recommended to measure the pressure vessel thickness using an U.S. device. My question is how to determine the number of test points on the shell/caps surface as a function of the pressure vessel size...

Thank you Baluncore & Lnewqban for the information and ideas.

Hi everyone, How to determine if a pressure vessel dome is eliptical or torrispherical (from external view on a complete pressure vessel, visually/basic measuring). Thank you.

Thank you Jrmichler & Baluncore, it is helpfull.

1. The test fluid is water 2. The height of the top of the vessel above the access port range is about 250-500 mm 3. The distance of the access port from the highest point in the vessel seems to me to the same question/answer as 2. 4. The test pressure range is betwwen 15- 20...

Thank you Baluncore, I think the concept is correct, but it would be better if you can attach a sketch to clarify the tubes connections ( 1/4” silicone tube & 1/4" metal tube ) and the way there are inserted ( with a float of closed cell foam ) into the ∅1/2" opening of the tank. Does a small...

Thank you, It is little bit comlicated to arrange at the field, though it makes sense. The openings I can use usually and practically are ∅1/2", sometimes up to ∅2", but I'll try to look for a solution in the direction you offered above. Thank you all

Hi everyone, I'll try explain... I am a qualified inspector for pressure vessels, and hydraulic testing means filling the tank with liquid (water) to the top of the tank, than using a hand pump raizing the internal tank pressure up to 150% of the design pressure for 30 min. Most of the...

I guess no. The tank is full with water

Hi, What can be done to avoid trupped bubble air at the top of a pressure vessel without upper hole during hydraulic testing? Also, once the bubble exist what can be done to release it? Thanks

Please refer to A-2 table (I've attached above), and explain what for Cp & Cv values stand? The title is odd, its for ideal gases @ 300 deg K (27 deg C). Water at this temp. are not vapor but liquid, unless you assume pressure is lower than atm. pressure.

No! That's not what I'm saying. Unless you did'nt notice, the A-2 table is related to 300 deg K!
