How to calculate the approximate weight of a 90 degree elbow if a elbow is 90 degree SR, or 2R, then how to calculate the approximate weight? It also have got a formula to get it. Please see as follows: The length of Back arc=R*1.57+OD/2*1.57 The length of Front arc=R*1.57-OD/2*1.57 so the actual length of raw material (pipe)=[(R*1.57+OD/2*1.57)+(R*1.57-OD/2*1.57)]/2 so when you get the lenth of raw material, you can easiy get the approximate weight othe the elbow using the formula that how to calculate the approximate weight of a pipe. Have you got it yet? How to calculate the approximate weight of stainless steel 90 degree LR elbow easily and quickly? There is a formula to get it. You can see it as follows: For 316L materail stainless steel elbow: Weight=(OD-WT)*WT*OD/1000*0.02507*2.3kgs Take 219*3.76 316L 90 LR Elbow for a example: (219-3.76)*3.76*219/1000*0.02507*2.3=10.22kgs For 304L materail stainless steel elbow: Weight=(OD-WT)*WT*OD/1000*0.02491*2.3kgs
