Degree of Bend Multiplier 10 degrees 6.0 22 degrees 2.6 30 degrees 2.0 45 degrees 1.4 60 degrees 1.2 Math From Triangles The geometry of a triangle provides formulas useful for many conduit bends Most conduit bends, in addition to a simple 90-degree bend, can be understood and calculated using the geometry of a right triangle. Miter bends. Another type of bend is a Miter bend. A Miter bend is a bend which is made by cutting pipe ends at an angle and joining the pipe ends. A true miter bend is a 90 degree bend made by cutting two pipes at 45 degrees and joining them by welding. Similarly three pipes cut at 22.5 degrees will give a 90 degree miter bend. A .473-in. die opening may produce an inside bend radius of 0.70 in. A .551-in. opening produces an inside bend radius of 0.082 in. And a .984-in. opening may produce an inside bend radius of 0.147 in. That's a huge radius variation, and the die width changed by about half an inch. edges using a 40-degree bend angle, Apply Auto-Mitering is cleared, and the corner relief is set to Trim to Bend. The preceding images show two views of the resulting model: viewed looking at the same face shown in Figure 6 (left) and slightly rotated (right). At this point the folded model browser structure is similar to Figure 3.

This video explain how to fabricate 45 deg Elbow from pipe?Miter bend calculation by using 2 cut 3 piece methodThis channel explain about piping isometric,nd we conducted extensive FEA to validate a number of mitre bends (90 deg , 4 segment bends, theta=30). asme b31.3 section 304.2.3 gives two formulae: one (eq 4a) which is independent of segment A (=M/2)and another one (eq 4b) which is dependent of segment A. our FEA show that (eq 4a) is too conservative but the Code says to use the "lesser value Then we can use above formula to get elbow angle for custom degrees. Same procedure applies to 3D elbows. Example 1: Calculate elbow center to end dimension for 4 inch nominal pipe diameter elbow at 60 degree angle, cut from 90 degree LR elbow. From ASME B16.9, center to elbow dimension for 4 in elbow is 152 mm. Length = Tan (60/2) X 152 I tried your suggestion of modeling the single-miter bend as bend with miter=1 (and i even experimented with 2 bend angles of 5 and 15 deg. each), but SIF always stayed equal to 1. The SIF will be the same for a 45, 38 and 90 degree bend. The bend angle will change the overall stiffness of the component through the changing arc length as RliOl.
