WebSIF Flexibility calculations are based on selected piping code. There are no code SIF equations that covers a branch welded to a Reducer. Therefore s elect "User" method and … WebMar 11, 2009 · The SIF's used in the ASME B31 Codes for Pressure Piping were derived from cyclic fatigue testing done before 1955 by A.R.C. Markl and his colleagues. NO ECCENTRIC REDUCERS WERE TESTED and so there is no data for the B31 Codes to base the calculation of SIF's for eccentric reducers - therefore there are no B31 SIF's for eccentric reducers. irig microphone instructions

WebMar 20, 2003 · Alpha is the reducer cone angle in degrees. Notes: alpha can not exceed 60 deg The larger of D1/t1 and D2/t2 can’t exceed 100 All of the codes supported by CAESAR II subscribe to one of these approaches. The codes that state that the reducer SIF is 1.0 don't require you to apply an SIF. WebApr 3, 2008 · In this application, the SIF at the weld can vary from 1.3 to a maximum of 1.9 (the 1.9 SIF would be for the 30 degree taper and more than 30 degrees is not allowed. Note that this reference addresses only the preparation and fit-up of the weld and the weld itself (at the diameter and wall mismatch) and it does not apply to any manufactured ... WebIn line with global efforts to save the environment and reduce global warming, SIF is committed to reducing energy usage and office consumables.
