    Compressed Air System

    I am looking for a calculation oriented book that guides the reader on how to select a compressed air system for an industrial plant. The book should have all the calculations presented in a step-by-step manner. Can you please recommend me a good book?

    heat insulated, cold insulated

    A pipe can be heat insulated, or cold insulated. What is the difference? Without the low thermal conductivity of insulating material, what else is going on?

    Barge sizes

    Barges are used to ship large vessels. Are there any size specification (sq. feet) for barges? Or it is really upto the manufacturer? Where can I read details about the construction of these barges. Who makes them? Can you give me some examples of companies who make them?

    nondestructive electric test

    The specification ASTM A 213 item 10 on page 6 talks about nondestructive electric test for heat exchanger tubes. What is this test for? Does it serve the same purpose as hydrostatic test? Where is it decribed? Is there any ASTM spec that details how to perform this test?

    liquid in pipeline (posted in PFM)

    This question was previously posted in BPV forum. I am trying this forum too. Sorry for the repeated post. How do you detect if a decomissioned pipeline has any liquid in it (remnant). You dont want to cut into the line. You got to use some kind of measurement technique to detect any liquid in...

    liquid in pipeline (posted in BPV)

    How do you detect if a decomissioned pipeline has any liquid in it (remnant). You dont want to cut into the line. You got to use some kind of measurement technique to detect any liquid in the pipe if possible. Any ideas?

    DIN

    A vessel fabricated in Germany and with most of the information on the drawing written in German language, has the following material info: " ... Material is 19Mn5 as per DIN 17155 with inspection certificate as per DIN 5004913C ..." The above could have typos since the drawing is very old...

    viscosity

    SSU is a unit of viscosity. I believe it is unit for kinematic viscosity (centistokes) and not dynamic viscosity (centiPoise). The relationship between centistokes and SSU is something like logarithmic or exponential - I dont know, but that is what I am trying to find! Where can I find an...

    heat tracing - second post

    I posted the following in a different forum. Thought may be I could get better response here! For a simple finite element model for flow of slurry through a pipe, boundary conditions on the pipe wall need to be decided. The different cases are: 1. Heat traced pipe 2. Steam-jacketted pipe 3...

    heat tracing

    For a simple finite element model for flow of slurry through a pipe, boundary conditions on the pipe wall need to be decided. The different cases are: 1. Heat traced pipe 2. Steam-jacketted pipe 3. Insulated pipe without any heat input 4. Bare pipe 5. Pipe with color applied to it. Typically...

    Shell & Tube exchanger pressure rule

    Is there any requirement per TEMA code on the maximum difference or ratio between the shell side and tube side design pressure? Can the shell side pressure be very high as compared to the tube side pressure? and vice verca? What is the 2/3 rule? I heard of it, but could not find it in TEMA code...

    stiffener rings

    A tall 304SS vertical tower is to be rated for Full vacuum external pressure. Stiffener rings are required per calculations. If stiffener rings are not allowed on the O.S., can they be put on the I.S.? If they are on the I.S., do they have to be continuous? Please refer to relevant sections...

    GASKET

    Why is it that typically Shell and Tube heat exchangers have double metal jacketted gaskets while nozzles on vessels have spiral wound gaskets. How do you chose one over the other?

    MM lb

    MM lb/yr production rate?? - Sounds like a unit that I have not come across before. Is it true that 1 MM lb = 1,000,000 lbs.?

    underground tank

    Does ASME Section VIII Div 1 cover construction of underground tanks? Please refer to appropriate reading. I guess one must account for the soil pressure on the tank and hence the depth below surface will need to be considered when it comes to external pressure calcs.

    tower structure

    One of the most typical shapes for a refinery tower has a larger lower section and a smaller upper section connected to each other through a cone. When it comes to erection of this vessel, the skirt can be easily attached to the lower section. Can a tower have a smaller lower section as...
