Hi all and Happy New Year,
Though design philosophies of Codes (especially for Tubesheets in case of HE Design) differ and cannot be cross-compared, given an option to select AD Merkblatt and ASME VIII-2, I seek suggestions on the selection for an exchanger to designed, manufactured and...
Thank you for the response. I couldn't catch up in time due to some personal reasons. Inner ring could not be ordered due to geometry constraints. However, we resolved the issue by replicating design of a fellow company having similar geometry and service - upon their consent.
Hi all,
We have a case where the mating flange has different surface finish compared to the top flange; one flange has a surface finish value of Ra 3.2-6.3 um, while the other has a surface finish value of 1.6 um.
As per my literature research, the SPW gasket works find under such...
Hi all,
I am new to HEX design and that too using AD Merkblatter Code. Using AutoPipe Vessel, I designed a custom weld-neck flange per B7 & B8 for my BEU exchanger. Subsequently, I designed tubesheet per B5 (6.7.3).
From the report generated by AutoPipe Vessel and further delving into...

@CuMo, @SnTMan, @r6155, @Krausen, @VFK, many thanks for the responses. From a cumulative understanding developed from your inputs, I opted for flexitallic PN type kammprofile gasket and took m and Y factors avaiable in their brochure.
Further, I checked SS type flange for Hydrogen Induced SCC...
Hello,
I am in a fix these days while designing a modified U-tube bundle for a heat exchanger on ASME VIII-I and TEMA ‘R’. Originally, exchanger had a 13 Cr-Mo 44 metal grooved gasket. Now while I am modifying the tube-bundle due to updated process requirements, I need to evaluate the exchanger...
