Case 2695
Code Case to Allow Section VIII Division 2 Design Rules to be used for a Section VIII Division 1 Pressure Vessel

Inquiry: Under what conditions may the Design-By-Rule Requirements in Part 4 of Section VIII Division 2 be used to design components for a Section VIII Division 1 Pressure Vessel?

Reply: It is the opinion of the Committee that the Design-By-Rule Requirements in Part 4 of Section VIII Division 2 may be used to design components for a Section VIII Division 1 Pressure Vessel, provided the following conditions are met.
a) The allowable design tensile stress shall be in accordance with UG-23 of Section VIII Division 1.
b) The weld joint efficiency shall be established in accordance with UW-11 and UW-12 of Section VIII Division 1.
c) Material impact test exemptions shall be in accordance with the rules of Section VIII Division 1.
d) If the thickness of a shell section or formed head is determined using Section VIII Division 2 design rules, then;
   1) For design of nozzles, any nozzle and its reinforcement attached to that shell section or formed head shall be designed in accordance with Section VIII Division 2,
   2) For conical transitions, each of the shell elements comprising the junction and the junction itself shall be designed in accordance with Section VIII Division 2,
   3) For material impact test exemptions, the required thickness used in the coincident ratio defined in Section VIII Division 1 shall be calculated in accordance with Section VIII Division 2.
e) The fatigue analysis screening in accordance with Part 4, paragraph 4.1.1.4 of Section VIII Division 2, is not required. However, it may be used when required by UG-22 of Section VIII Division 1.
f) The provisions shown in Part 4 of Section VIII Division 2, to establish the design thickness and/or configuration using the Design-by-Analysis procedures of Part 5 of Section VIII Division 2 is not permitted.
g) The Design Loads and Load Case Combinations specified in Part 4, paragraph 4.1.5.3 of Section VIII Division 2 are not required.
h) The primary stress check specified in Part 4, paragraph 4.1.6 of Section VIII Division 2, is not required.
i) Weld Joint details shall be in accordance with Part 4, paragraph 4.2 of Section VIII Division 2, with the exclusion of Category E welds.
j) The fabrication tolerances specified in Part 4, paragraphs 4.3 and 4.4 of Section VIII Division 2 shall be satisfied. The provision of evaluation of vessels outside of tolerance per Part 4, paragraph 4.14 of Section VIII Division 2 is not permitted.
k) The vessel and vessel components designed using these rules shall be noted on the Manufacturer's Data Report.
l) All other requirements for construction shall comply with Section VIII Division 1.
m) This Code Case Number shall be shown on the Manufacturer's Data Report.
