Paragraph 26-6.3.3: revised formula S2,E to account for the effect of the collar in U-shape unreinforced bellows. Paragraph 26-6.4.1: deleted the two options conceming instability due to intemal pressure. Paragraph 26-6.3.2 revised the fatigue formulae for unreinforced bellows, reinforced bellows (para. 26-7.3.2), and toroidal bellows (para. 26-8.3.2) to limit the calculated allowable number of cycles to 1 million cycles. Paragraph 26-12: revised to limit the test pressure to prevent instability of the bellows during the pressure test, as required by B31.3 and EJMA. Included UNS S32906 in Table UHA-23. Revise Fig. UW-16-1, (f-2) dimension "~ tmin" to "minimum of 1~ f'. Addition of UNS A95083, A95086, A95456 Revised U-l(g).
UG-ll(c)(5) added to clarify that the vessel Manufacturer is to verify that welded standard pressure parts comply with the rules of this Division. Revised UG-136(c)(3) to require pressure relief valves with adjustable blowdown to have control elements posi­ tioned typical of production methods prior to conducting the capacity flow test. Revised heading of UG-134 to read, "Pressure Setting and Performance Requirements." Added new para. UG-134(f) clarifying requirements regarding pressure relief valve chatter and flutter. Referenced UG-134 within UG-136(c)(3)(c). Required vessel markings regarding the use of ultrasonic examination using Code Case 2235-6. Revised UG-116(e) and UG-116(e)(l). UHX-12.4(d): Added note that states aU-tube tubesheet may be designed as simply supported. UHX-12.6: Provided rules to design aU-tube tubesheet as simply supported. UHX-13.4(g): Added note that states a fixed tubesheet may be designed as simply supported. UHX-13.9: Provided rules to design a fixed tubesheet as simply supported. UHX-14.4(g): Added note that states a floating tubesheet may be designed as simply supported. UHX-14.7: Provided rules to design a floating tubesheet as simply supported.
