Mitered Pipe Bend

Carbon Steel Miter 90 Degree Elbow and Stainless Steel Fabricated Bend manufacturer in India

Mitered Pipe Bends are common these days. A miter pipe fitting is something made up of more than one piece of pipe welded together in different angles. So a mitered bend is essentially more than one piece of pipe welded together to bring the desired angle. For example, two pieces are welded in 45 degree angle cuts to bring a 90 degree mitered bend. The ASME B31.3 Mitered Elbow Manufacturer in India belongs to a standard which includes pipes of 1/8 inches through 12 inches in diameter. There are different sizes of SS mitered pipe bend and fittings.

The Carbon Steel Miter 90 Degree Elbow is made up of carbon steel and has a 90 degree angle. The single miter bend and elbows could be used interchangeably when specific requirements are not there. There are Mild Steel Long Radius Miter Elbow types and the Miter Cut Elbow types. Depending on the need of the applications, mild steel could be used when the corrosion stress, temperature and pressure are low.

Stronger materials are used with high stress applications and high corrosion resistant materials are used with highly corrosive environments. The 45 Degree Miter Elbow is different in that it only changes the direction in a 45 degree angle. There are different shapes of the diameter which result in different types of elbows and bends such as the Rectangular Miter Elbow. They all have various applications such as the Mitered Bend Pipe that are used in high temperature services like the exhausts.

Miter Elbow Formula

---

In upper image, dashed lines shows where the pipes needs to be cut. Every dashed cut line incorporates a vertical reference line marked at following distances from pipe finish.

• – Cut Back : Offset distance of cut lines from reference lines at the pipe bottom and top.
• – L1 : Distance between reference lines.
• – L2 : Distance Between the first and the last reference line from pipe end.

Miter Elbow Input values:

• – N = 4 : No. of cuts
• – D = 90 mm : Required Miter Elbow Degree
• – POD = 273 mm : Pipe O.D.
• – E = 381 mm : Standard Radius of Miter Elbow

Weight Calculation of Miter Elbow

---

Weight = 2*R*n*tan(alfa/(2*n))*W, where

alfa = bend angle (total)
n = no. of miter joints
W = Unit weight of pipe (kg/ m or lb/ feet)
R = bend radius at end (=circumscribed)

ASTM A403 WP304 Miter Bend Calculation

Required Inputs for Calculation :

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.

➤ Step 3: Locate the Angle of Cut.

➤ Step 4: Finding the CL1 (i.e. Center Line Length) of the First Miter.

Using Pythagoras formula,

NOTE :

• ➊ The first and last miter will always be of the same length at every point.
• ➋ 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 5: Calculate Outside and Inside Radius (OR & IR) of the bend.

➤ Step 6: Calculate the IL1 (i.e. Inside Length) of the First Miter.

Using Pythagoras formula,

Therefore,

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

➤ Step 7: Find out the OL1 (i.e. Outside Length) of the First Miter.

Using Pythagoras formula,

Therefore,

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

➤ Step 8: Find the "Length of Pipe required" for the Miter Bend.

❯❯ Length of pipe required = CL1 + Cutting allowance + CL2 + Cutting allowance + CL3 + Cutting allowance + CL4

NOTE : Cutting allowance depends upon the cutting method used, we are assuming 5 mm.

❯❯ Thus, L = 136+5+272+5+272+5+136

❯ L = 831 mm

➤ Step 9: Calculating the Weight of the Pipe.

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

Points To be Considered about Fabricated Bend

---

• ✔ Experienced skilled welders and fitters are required for perfect miter bend preparation.
• ✔ Used mainly in general services (category “D” fluid).
• ✔ If used in process lines then above 14” pipe size.
• ✔ Miter bend can be fabricated with 2, 3, 4, & 5 miters.
• ✔ It is also called fabricated bend.
• ✔ The numbers of cut will be a maximum of 5.
• ✔ Miter bends are not standard fittings.
• ✔ Used above 6” for utility lines.
