Tube to tubesheet shear load test

[leon_har_dt]

Hi all i hope you are doing well.
now that this shear load test may be mandatory in 2023, it dont see in figure UW-20.3 how the load is applied. The tube need to have some weld piece in the end for the plunger?
Where i can find a real configuration to perform this test?

I'll appreciate any answer

Best Regards

UW-20 is clear. Read again.

Tube push-out tests are very common.
If you don't find it clear in UW-20 ask someone that re-tubes HXs.
This is often part of the qualification process.

Thanks a lot for your answer
I read again and it confuse me when the UW20 do a push out configuration but the ASTM E8 do a pull out. It can be interpreted as the same test? Thats why i ask if in the end of the tube it should be weld some piece to perform the push.

Here where i come from it can be a very rare case where this test are done. So i'm learning while doing.

Best Regards

Mechanically it is easier to do this as a pushout.
You don't have to grab the tube.
Many people fold the ends of the tubes and push then push on them.
