Figure 2 A bend angle in tube bending usually is calculated from the outside—the complementary bend angle. Other critical dimensions are the wall thickness (which thickens on the inside radius and thins on the outside radius) and outside diameter.

To calculate total pipe length, add distance from end of pipe to the first bend, plus first bend arc length, plus distance to second bend. Consult factory for special tooling request. Angle of Bend Material Consumption for Bend Angle Centerline Radius x Degree of Bend x .0175 = Length Radius (CLR) Required Tangent Excess Material Inner Wall ... Mar 14, 2018 · The radius is also half of the diameter, which is the distance between two points on the circumference that passes straight through the circle's center. You can calculate the radius of a pipe through its diameter or circumference.
