Miter Bend manufacturer in India

Manufacturer of carbon and alloy steel 90-degree mitered elbows


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:

  • They are low in cost.
  • It does not require any thinning.
  • It can be made both in a workshop or site.

However, there are some demerits of Miter Bends too, like:

  • Due to the multiple joints, they do not possess high strength
  • Corrosion resistance capacity is also less due to multiple weld joints..
  • They cannot withstand high pressure or high turbulence.
  • They are unsuitable for pigging.
  • Needs highly skilled workmen for manufacturing.

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

Calculation Steps:

Step 1: Note the data from above table

  • Pipe O.D. = 219 mm
  • D = 8 inch
  • Bending Angle = 90°
  • Schedule = 120
  • Material = Carbon Steel
  • No. of cuts = 4
  • R = 2.5 D = 2.5*8*25.4 = 508 mm

Step 2: According to no. of cuts, outline the drawing as below figure.

Miter Bend Calculation

Step 3: Finding the CL1 (i.e. Center Line Length) of the First Miter.

Using Pythagoras formula,

Center Line Length

NOTE :

  • The first and last miter will always be of the same length at every point.
  • Excluding the last miter, all the miter’s length will be twice of the first miter at each point.

Therefore,

  • CL2 = CL1 * 2 = 272 mm
  • CL3 = CL1 * 2 = 272 mm
  • CL4 = CL1 = 136 mm

Step 4: Calculate Outside and Inside Radius (OR & IR) of the bend.

Inside and Outside Radius

Step 5: Calculate the IL1 (i.e. Inside Length) of the First Miter.

Using Pythagoras formula,

Inside Length

Therefore,

  • IL2 = IL1 * 2 = 214 mm
  • IL3 = IL1 * 2 = 214 mm
  • IL4 = IL1 = 107 mm

Step 6: Find out the OL1 (i.e. Outside Length) of the First Miter.

Using Pythagoras formula,

Outside Length

Therefore,

  • OL2 = OL1 * 2 = 330 mm
  • OL3 = OL1 * 2 = 330 mm
  • OL4 = OL1 = 165 mm

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

90 Degree Miter Bend

Where the pipe should be cut is shown in the above figure by the dotted lines. On each dotted cut line, a vertical reference line is drawn at the following distances from the pipe end.

  • L2: The distance between the first and last reference lines from the pipe ends.
  • L1 is the distance between two reference lines.
  • Cut Back: The distance between the cut lines and the reference lines at the top and bottom of the pipe.

  • Miter bends are not common fittings.
  • It is also known as manufactured bend.
  • Perfect mitre bend preparation necessitates highly trained welders and fitters.
  • Mostly used in general services (type "D" fluid).
  • When utilised in process lines, pipe sizes larger than 14" are recommended.
  • Utility wires with a diameter greater than 6" are used.
  • Miter bends can be made with 2, 3, 4, and 5 mitres.
  • The number of cuts will be limited to a maximum of five.
  • Due to the increased number of joints, there is a decrease in strength.
  • Pressure drop is greater.
  • Increased turbulence.
  • Corrosion risk is increased due to the increased number of weld joints.
  • There is less strength.
  • Pigging is not permitted.
  • High-skilled labour is necessary.

  • Pipe Type = Seamless
  • S = 20000 psi
  • E = 1
  • W = 1
  • R1 = 1.5D = 1.5x12x25.4 = 457.2 mm
  • (T-C) = 2.55 mm
  • T = 6.35 mm (SCH20)
  • Mechanical Allowance = 12.5%
  • Corrosion Allowance = 3 mm
  • r2 =(D-T)/2 = (323.8-6.35)/2 = 158.72 mm
  • Bend Angle = 90°
  • C = Mechanical allowance + corrosion allowance = 0.79+3 = 3.79 mm

Put the given value in equation (4a)

Equation

Where,
θ = (Bend Angle/Numbers of Miter or cut) / 2 = (90°/2) / 2= 22.5 °

Therefore,

Equation

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
