What is Miter Elbow?
Miter bends are not standard fittings because are fabricated from pipes. High skill pipe fitter is required to manufacture this type of Miter Type Elbow. Long Radius Miter Elbow preferred size is min 10” & above as large size elbow price is very high compare to other steel buttweld elbows. All types of ASME B31.3 Miter Elbow such as Round Duct Miter Elbow, Rectangular Miter Elbow, Miter Round Elbow, Miter Reducing Elbow & Miter Joint Elbow can be fabricated in 2, 3, & 5 pieces.
A Miter Bend or Elbow is a joint made by beveling each of two pieces to be joined, usually at a 45° angle, to form a corner, usually a 90° angle. There are two types of mitre joint, one Non-perpendicular joints & another is Three-dimensional joints. AWWA C208-96 Miter Elbow are produced from miter cut pieces of pipe. The Miter pieces also called gores which used to make Mitered Elbow. You will found two end gores and three middle gores in a 5-piece Miter Pipe Elbow. As per the AWWA specification the radius of a 60" elbow is 90". The “center-to-face” is 92.065".
AWWA Recomends:
22.5< to ≤ 45, use 3 pieces
45 < to ≤ 67.5, use 4 pieces
67.5 < to ≤ 90, use 5 pieces

Miter Elbow Weight
Weight = 2*R*n*tan(alfa/(2*n))*W, where
R = bend radius at end (=circumscribed)
n = number of miter joints
alfa = bend angle (total)
W = Unit weight of pipe (kg/m or lb/ft)
Steps to calculate miter elbow weight
- calculate the total length of the bend using the formula, l=r x theta, where r=radius of the center line of the bend and theta = bend angle in radians.
- Unit weight of the pipe/ metre can be obtained from the pipe manufacturer end or from the relevant codes and standard governing the material and process of manufature of the pipe piece used for fabricating the pipe bend. for example: in case the pipe piece grade is API 5L, then refer API 5L for unit weight per meter, or you can refer ASTM A53 code for ASTM pipes and so on.
- And then multiply the unit weight per meter calculated in step 2 to the length of the pipe piece calculated in step 1.
Formula of Miter Elbow
In above pic, dotted lines shows where the pipe should be cut. Each dotted cut line has a vertical reference line marked at following distances from pipe end.
- L2 : Distance of first and last reference line from pipe ends.
- L1 : Distance between reference lines.
- Cut Back : Offset distance of cut lines from reference lines at the top and bottom of pipe.
Given a formula to make 90 degree elbow of 10" size with elbow center radius same as standard elbow i.e. 381 mm.
Miter Elbow Input values:
- D = 90 mm : Required Miter Elbow Degree
- N = 4 : Number of cuts
- E = 381 mm : Standard Miter Elbow Radius
- POD = 273 mm : Pipe Outside Diameter
