Normally custom elbow joint angles from 45 degree to 90 are cut from 90 degrees basic joint. For personalized arm joint angles smaller than 45 degree, the elbow is typically cut from the existing standard 45-degree joint. To finish measurement offered in dimension tables for 45-degree elbow joint need to be divided by Tan( 22.5) to obtain the arm joint radius for a basic 45-degree joint.
Calculate Elbow Center Example:
Calculate arm joint center to finish dimension for 2 inch nominal pipeline size arm joint at 30 level angle, reduced from 45 level LR elbow joint.
From ASME B16.9, the facility to elbow dimension for 2 inch 45 level elbow is 35 mm.
Span of elbow = 35/Tan( 22.5 )
Span of elbow joint = 35/0.4142 = 84.5 mm
Length = 0.26795 X 84.5= 22.64 i.e. 23 mm Approx.
