Hello All,
My Engineering Firm was just awarded a project to replace (2) existing nozzles with (4) new nozzles that are a size larger on a boiler steam drum. We are contracting out the engineering of the nozzles to a proper PE, and we are doing the piping design that will attach to the...
Can anyone explain to me why temperature change is not considered a sustained load, when the system is operating for a long period of time without shutdown? Or is there an accurate way to consider the full operating case(T1,P1,G) and what method of calculating the allowable would be used?
Hello,
I am currently working on a project where I am designing a piping system in need of expansion joints. The system is large and there is no room for expansion loops, so expansion joints is our best option. However my problem begins dealing with the expansion joint manufacturer.

Duct Design Experts,
How do I determine if my circular duct design needs stiffening rings? And, if it does need them, how do I determine the correct member size for the stiffener?
After reading "The Structural Design of Air and Gas Ducts for Power Stations and Industrial Boiler...
Hello,
I am having trouble modeling a boot on a horizontal vessel. I attached the cylindrical section at a nozzle but the vessel has a conical reducer to a nozzle at the the bottom of the boot. Does anyone have any advise on how to model this correctly in Compress?
Thank you.
I am trying to design an additional nozzle on an existing furnace and I have a question that my see elementary to some but I would rather ask than continue falsely. I have been reviewing Part UG of the BPVC, specifically UG-37 through UG-45, and most of these sections discuss nozzles on round...
From experience, what are some good materials that have minimum embrittlement and good creep rupture strength during long periods of operation at 1000 deg F? This is for a large diameter duct project.
Also, are there other material properties that I should be concerned with when dealing with...
Hello,
I am a young mechanical engineer that is starting a new project to design a new section of duct that will be bypassing and existing stack and rejoining an incinerator outlet just before a new HRSG unit. The duct is 12'-6" in diameter and the air in the duct at the tie-in is 1000ºF. The...
