Hello Experts. I'm already work with a data sheet of an acid flare KO drum.. It is mentionned that the material used is CS+6mm at 3.5 kg/cm2g design pressure and 150°C design tempertaure. from your point of view, Is the selected material for those condtion with a fluid containing Acid gas and...

HI EXPERTS MY QUESTION IS : How Can I classify the HRSG? is this unit is fired or not fired boiler?? Cordially :)

Hi experts; please, what isthe differencies between hub flange and pad flange?

Hello guys, I'm facing at these requirements: -Fixed tubesheet exchanger can be used if shell side fluid is clean i.e fouling resistance <0.0002 hr m2.°C/Kcal. the question is : is the fluid is considered as a clean where the fouling resistance is lowest??? Cordially [dazed]

Hello I'm facing at a datasheet of drum in vertical postion where the drain is not at the lowest point of the vessel !!. is there any passage in standrad/norm that treat this preoccupation, As I know that the drain must be at the lowest point and the vent at the hieghest point of the vessel...

Hello Experts; The question : is there a limitation of manway/manhole size related to the inner diameter of the vessel? I mean is there o formula or standard/norms that give a relation between the size of the vessel and the size of manholes? Thank You ;)

Hello Experts; I'm facing at a datasheet of a vessel where it is mentioned that the material of constrcution is : CS+6mm CA+ Cladding. The question is that I know that where cladding is used no additional corrosion allowance is needed, is there any norm or standard that confirm this?! cordially ;)

Thank you Mike :)

Hello, please is there a diffrence between a girth flange and a body flange? if it is the case what is the meaning of the two and if there is any doc or book mention these special types.

Hello dear expert, What is the minimum size (inside diameter) of a vessel according to ASME SEC 8.

Hello everybody; plz what is the difference between the two series A and B of flange for large diameter? and how to choose between the two?

Hello an thank you for evryone for your response; Our specification said that the tabular loads shall be considered as being caused by 66% thermal and 34% dead weight loads, IN Excel sheet of loads on nozzles the loads are sustained, occasional and expansion load, so my understanding is: 1) for...

Hello experts my question is about allowable loads on nozzles for pressure vessel. the standard of the company wich I work at, has tabular alloawble values of forces (Fa,Fc,Fl) and moments (Mt,Mc,and Ml) according to flange rating. The problem is when I choose to analyse loading for nozzles...

Hello world, I'am a fresh mechanical engineer and I'm trying to re-design an existed pressure vessel just for training and get familiar with PV design. I have many questions and problems that maybe are basis for experenced one. 1- Is ir necessary to set values of Projection from Top,Projection...

Thank you a lot for this rich message.
