2007年4月10日 · Your minimum nozzle thickness is (b)(3) but need not exceed Standard wall (0.375)(7/8)+0.1 = 0.43" so your minimum nozzle thickness based on UG-45(b) only is 0.30" Keep in mind that you will check the nozzle thickness for …

2012年12月14日 · The (2) .119 diameters on the attached dwg are raised bosses. The .226 diameter is a hole. Datum A is the common planar surface these features are normal to. What we are trying to accomplish with the GD&T is first hold the 2 bosses center to center dim to .000 TP if at MMC with bonus tolerance...

2014年12月5日 · According to my source, "Cold-formed Steel Structures" by W. Yu the expression for a cold-formed channel agrees with your second reference when t f = t w if the dimension 'b' is taken from the middle of the web to the end of the flange. Comparing this with your first reference: t f = 12.7 t w = 7.2 b = 70.4 h = 292.3

2025年2月18日 · 1) Don't mix units like you've done. Use the exact units written in B 31.3. 2) Why have you added 3mm CA for a stainless steel pipe? 3) S value for you is not 20 ksi, but 16.7 wt with 0mm CA is now 0.155 in, within the wt for sch 80S …

2017年6月4日 · b. 0.392” c. 0.350” d. 0.142” The answer sheets says that the correct answer is b 0.392 referring to B31.3,304.1.2 (a). But when I use that formula to calculate the thickness I get 0.0418” for pressure design thickness. If we add 0.1” for corrosion allowance we get for minimum required thickness 0.1418”.

2014年5月13日 · Look at the picture. You see how datum axis A-B is derived from datum features A and B. You probably will have no problem with the idea of checking relation of axis A wrt axis A-B, because they are definitely not the same. Now let’s move to parallel cylinders. Datum A-B is neither features A or B, but the thing of its own, derived from both.

2007年5月16日 · Given that, one of the secondary windings will be V ca = 480?120 and the other will be V ab = 480?0. The missing voltage, V bc = -(V ca +V ab) will calculate to be 480?240. In each case, V ab will have the same phase angle as V AN, V bc will have the same phase angle as V BN, and V ca will have the same phase angle as V CN. If you are getting ...

2005年2月24日 · UG-44(b)(4) formula is used only if you want to evaluate the flange joint for the external loading. For this, you have to know the piping load (forces and moments) exerted on the vessel flange. For determining the P-T rating, simply use ASME B31.3 Appendix L.

2003年1月29日 · I have a drawing of a part that defines its final geometry. This part is a casting and the current vendor both casts and machines the part. Some areas of the final part remain as cast. Any suggestions for a concise note: I need to say that draft angle is acceptable for casting purposes as long...
