What Is Miter Bend?
A bend made by cutting the ends of a pipe at a specific angle and then uniting the ends of the pipe is known as a mitre bend. Non-perpendicular bend and three-dimensional bend are the two different types of mitre bend. A four piece Miter Bend has two centre sections, two end pieces, and milter pieces, also known as gores. It should be noted that these fittings are not commonplace. Miter bends require highly skilled workers, who are typically employed in general labour. A mitre bend may have up to five cuts. The advantages of this fitment include:
However, there are some demerits of Miter Bends too, like:
How To Make Miter Bend?
When two pipe ends are cut at an angle of 45 degrees each, they are united by welding to create a genuine mitre bend, which has a 90 degree bend. Similar to this, a 90 degree mitre bend can be created by joining three pipes that have been cut at a 90 degree angle.
How Do You Calculate Miter Elbows?
The radius of the centerline of the bend and the bend angle are multiplied to determine the length of a mitre bend or mitre elbow (in radians). Hence, l=r*.
What Is Considered A Miter Bend?
Miter bends are created by cutting the ends of pipes at an angle—typically 45 degrees—and then putting the pieces together by welding to create a bend—typically at a 90 degree angle.
Where To Use Miter Bend?
Similar to bend pipe fittings, the mitre bend aids in changing the pipe run's flow direction. They are mostly employed in general services, such as for fluids in category D. Only when the pipe size is greater than 14 may they be used in process lines.

Calculation Inputs Needed:
Pipe/Line Size | No. of Cuts | Material Type | Bending Angle | Sch Number | Radius of Bend |
---|---|---|---|---|---|
8″ | 3 | CS (Carbon Steel) | 90 | SCH 120 | 2.5 D |
Note: D = Pipe / Line size
Step 1: Note the data from above table
Step 2: According to no. of cuts, outline the drawing as below figure.
Step 3: Finding the CL1 (i.e. Center Line Length) of the First Miter.
Using Pythagoras formula,
NOTE :
Therefore,
Step 4: Calculate Outside and Inside Radius (OR & IR) of the bend.
Step 5: Calculate the IL1 (i.e. Inside Length) of the First Miter.
Using Pythagoras formula,
Therefore,
Step 6: Find out the OL1 (i.e. Outside Length) of the First Miter.
Using Pythagoras formula,
Therefore,
Step 7: Find the "Length of Pipe required" for the Miter Bend.
Length of pipe required = CL1 + Cutting allowance + CL2 + Cutting allowance + CL3 + Cutting allowance + CL4
ASME B 36.10M-2015
Plain End mass is given 90.44 kg/m as per ASME B 36.10 M
Now,
Finding the weight using the following formula
Weight of the Pipe = Plain End Mass * Length of Pipe ( in meter)
Weight (W) = 90.44 * 0.831 = 75 kg
Step 10: Get the Cut-back.
Cut-back = CL1 – IL1
Cut-back = 136 – 107 = 29 mm

Input Required
Put the given value in equation (4a)
Where,
θ = (Bend Angle/Numbers of Miter or cut) / 2 = (90°/2) / 2= 22.5 °
Therefore,
Pm = 103.60 psi
We can see Pm< Pdesign
So, increase the numbers of the miter to 3 and recalculate (only the value of θ (15 °) will be changed, rest will be the same.
Now,
Pm = 136.19 psi
Still,
Pm< Pdesign
Similarly, for 4 miters, (θ =11.25 °)
Pm = 159.93 psi
Still,
Pm< Pdesign
Similarly, for 5 miters, (θ =9 °)
Pm = 178.16 psi
