Following options are available for the connecting tube/tubesheet welds:
|
Full Strength |
A full strength tube-to-tubesheet weld is one in which the design strength is equal to or greater than the maximum allowable axial tube strength. In other words the joint is at least as strong as the tube. |
|
Partial Strength |
A partial strength weld can be designed based on the actual tube-tubesheet axial load |
|
Seal Weld/No Weld |
No calculations are performed in this case. |
Information on these weld types can be found in the ASME Code Section VIII Division 1 paragraph UW-20.
