Per ASME code, or appropriate TEMA standards, is there a design calculation for the minimum tubesheet thickness required in the fabrication of a Fire Tube Boiler? Any thoughts would be greatly appreciated.
We are looking for a formula to determine the volume of a dished head as a function of height; or the height measured from the flange connection of the head vertically to the head's top. For example, what volume is contained in a dished head measured vertically 1" from the flange...
Thanks everyone for the excellent feedback and comments. Your guidance on the appropriate standards to refer to helped nail down the meaning of undercut.
Last year, our plant consulted with a metallurgist on some weld defect issues associated with our continuous casting belt. The belt is a 0.060" thick piece of stainless steel, 12 meters across, and about three football fields in length. It's welded in multiple areas to join the stainless...
Thanks for all of your insight. We reviewed our application with the local jurisdiction, and apparently, ASME section I or section VIII is applicable. It's a design choice. In our case, the boilers were designed to section I to achieve improved mechanical integrity. However, based on applicable...
The state of Tennessee desires to classify our Waste Heat Boilers as "Power Boilers". The subject boilers cools process gas which consists of SO2 for the purpose of making 450# steam. As an organization, we wish to challenge this classification, and categorize the subject boilers as...
