ASME Sec VIII Div 1 Code Case 2260-1

ASME Sec VIII Div 1 Code Case 2260-1

ASME Sec VIII Div 1 Code Case 2260-1

(OP)
I saw on asme.org that code case 2260-1 was annulled on June 28, 2012. Does anyone know if the alternate design basis was incorporated into the base code? I have an application for which it is well suited (high strain acceptable, low cycling, moderate temperature, etc.) but do not know the status of it since it is listed as unpublished.

RE: ASME Sec VIII Div 1 Code Case 2260-1

Here is an excerpt from the C&S Connect on this item;

There are four reasons that Case 2260 should be annulled:

1. These rules have become outdated relative to the more advanced rules that are now published in Part 4.3 of VIII-2.

2. Today Section VIII-1 Certificate Holders can use the Section VIII-2 head design rules via Code Case 2695.

3. Subgroup Design of Section VIII has determined that when the more advanced head design rules of VIII-2 are used, it is necessary to also use the VIII-2 opening reinforcement rules to maintain consistency in the design. Since Case 2260 did not consider opening reinforcement within its rules, this is another reason that annulment of Case 2260 is appropriate, and Section VIII-1 Manufacturers should use Case 2695 to design thinner heads using the rules in VIII-2.

4. SGD has opened an item to consider replacing the head design rules in VIII-1 with the rules from VIII-2. Until this takes place, Case 2695 will continue to provide access to head design rules in VIII-2 for VIII-1 Certificate Holders.

This Code Case annulment was approved by letter ballot.

Thanks for the info, metengr. I will use Case 2695 then.
