Thanks r6155!

You can still use ANSI flanges on both sides even if there are partitions. Purchasing ANSI flanges is cheaper than designing your own and machining your own flange. r6155... 50%, no way....considering shop rates for machine time etc.. it evens out around 18-20 NPS flanges. marty007, You...

Per Brighton Tru-Edge... Inside Knuckle Radius is Approximately 15% of the Diameter (See ASME Section VII, Division 1, UG-32 for clarification)

Good Morning, Yes you can use ANSI RF or WN flanges on TEMA R units. However, the gasket must be contained per TEMA R. So the gasket must have outer and inner metal reinforcement rings. This is out of TEMA 10th Ed. If you have any other questions let me know. I design Shell & Tube Heat...

Good Morning Everyone, I have been studying the Megyesy Handbook and forums on here on how to calculate legs such as the picture below. Please ignore the orange selection box. I am only using this image to represent the legs. I am not seeing how to calculate this scenario. I did make an...

Thanks for the reply's guys, Yes we are talking about the rail system currently and have had the same thoughts. Our baffles are normally fixed tight with only the tubes growing etc with the thermal expansion through the baffles. So in a sense the railing would not effect that too much. 2...

We notch the baffles and weld in the flat bar so there is enough hanging out to prevent the baffles from scraping. Some bundles go from 200# up to 9000# depending on the unit. So I understand that 1 system may not work across the board for all unit sizes. What have you seen for channel with...

Good Afternoon Everyone, I have a question regarding bundle supports. Bundles are assembled with tie rods and spacers. Currently I use flat bar at 20 degrees from center on the bottom each side of the baffles as slide rails against the shell to keep the baffles from dragging for removable...

Thanks for the input guys. Our QC checked into it with the NB and they told us that what we need is the ASME/NB ID plate with only the shellside information and a second ID plate with only the tubeside information, but no ASME or NB stamp. We will then only hydro test the shell side and note...

Going by the UHX & Tema, it states that both the shell side & tube side shall be hydrotested seperately. I have a unit that the customer requested that the tube side not be rated as it has very low pressure. According to the code, can we just test the shell side and still be ok? We are...
