Similar method as presented has been applied to design compact flange joints with great success for many years. 47 flange pairs can be inserted between vessel body seams; After an Appendix 2 flange is placed and fully designed, flanges added after the fact will retain the same dimensions and design parameters if the flange is attached to a component the same size and utilizes the same flange type Jul 25, 2019 · The actual number of bolts n b in the flange design can only be determined using a norm calculation such as ASME VIII Division 1 - Appendix 2 which will show if there are enough bolts to keep the gasket closed. Although not recommended, TaperSeal ® hub flanges are capable of extreme misalignment, up to 20 degrees. 4 Swivel ring flanges (c) the face of the first flange for bolted, flanged connections; (d) the first sealing surface for proprietary connections or fit-tings; U−1(e)(2) where nonpressure parts are welded directly to either the internal or external pressure retaining surface of a pressure vessel, this scope shall include the design, fabrication, The first proposed standard was submitted to the Committee in April 1926 and approved by letter ballot in December. This design avoids the high flange bending stresses found in a raised face flange (of Appendix 2) and will result in less flange thickness. 1 and this force designers to often increase thickness of flanges in order to ensure proper tightness. 2]. ASME PCC-1-2010; ASME B16. This adds consideration for tensile forces and overturning moments for the selection of rated flanges.
