Hello, We are planning to install an agitator in the bottom head of the vessel. My question: are there any specific requirements to the roughness (AARH) of the face of the flange connected to the mounting flange of the agitator?

I am a mechanical P.Eng. I am just starting to work as a contractor for an engineering consultant company. My contract with the Company states that I am responsible for buying liability insurance. Could anybody tell me how much a typical annual premium for professional liability insurance and...

Have you noticed how many engineers are married to nurses? In every company I've every worked for there are always a few, A FEW. Actually, I can not think about any other occupations which follow the same pattern.. I am always puzzled by questions: why engineers and nurses? how do they actually...

Hello, Is it correct to use the acronim "MDMT" if talking about vessesl saddles? Fo rexample, if the vessel saddles to be exposed to -50 deg C, shall I mention MDMT or MMT (minimum metal temperature)= -50C? I was under the impression that "MDMT" applied only to pressure envelope. Thanks.

This is great, thanks a lot!

lostsailor, So, if the code case 2211 was approved - as metengr mentioned -in 1999, it supposed to be included in 2004 Ed. of Code, but it is not there. Could you please suggest where else I might be able to find it? Thanks.

Thanks metengr!

Hello, I can not find in our library any reference to ASME Code Case 2211 "Pressure Vessels with Overpressure Protection by System Design". Is this a separate document or it is a part of the Code? Thank you.

I would live only in San Francisco. Nothing can compete to this. Yes, it is expensive, but the life surrounded by SF beauty and spirit worth everything.

Hi, What is "full-range pressure cycle"? Thanks.

Hi, I have a simple question - from which length / diameter (or diameter / length) ratio the vertical vessel is considered a tower (column)? I have a Pressure Vessel handbook, but there is no information about this particular question. Thanks!

Hi, In our project specification we've asked the Vendor to hydrotest vessel to 1.3 MAWP (new& cold). I've got a question from them - which hydrotest pressure shall be mentioned on the vessel nameplate, 1.3 x MAP new&cold or 1.3 MAWP (the pressure of the test done at the field)? Their concern...

Thanks, bmoorthy, I've read this standard. I'm interested more in practical side of the issue.

Thank you very much, it is exactly what I need!

Thanks, I've already checked John Zink website and didn't find any reference to the required matter.

Hi, I'm evaluating the flare stack bid proposal. The flare is 37 m high. One Vendor had included in the quote the aircraft warning lights, but the other one did not - he had mentioned that per ICAO recommendations, it is not needed for the flare of this height. The question: is ICAO the only...

Hi, I'm doing a bid evaluation for flare stack and try to evaluate the options for pilot flame monitoring: thermocouples, UV or infrared monitors, ot acoustic monitors. Do you have expierence with any of this? What is your favorite? Why? Thanks.

Thank you, it helps a lot. Unclesyd, that's funny.

Hi, I can't find any info in the Code regarding correlation between vessel length and quantity of the manways required. Is there anything (except common sense) to justify how many manways shall be on the long vessel (9 m and up)? Thank you.
