Bending a pipe in a required radius of circle by without applying any external source of heat on the pipe is cold bend in pipeline.
I believe you want to know the MINIMUM bending radius of sheet metal. The maximum bend would be 180 degrees.
Worught Pipe Bend
Where it is not possible to bend a pipe due to lack of equipments or the thickness of the pipe, the miter bend is made by cutting the pipes at desired angles.
Bend meter is a type of pipe which are bend may be sharply or 90 degree . In fluid mechanics we calculate the losses inside the pipe .in which losses are more.
The term "pipe bending radius 40D" refers to the minimum radius at which a pipe can be bent, where "D" represents the diameter of the pipe. Therefore, a 40D bend means the bending radius is 40 times the pipe's diameter. For example, if the pipe has a diameter of 2 inches, the minimum bending radius would be 80 inches. This specification helps ensure the integrity and performance of the pipe during bending, preventing kinks or damage.
The RADIUS of a 5D pipe bend is actually what is 5 times the nominal diameter. So if you had a 10" diameter pipe, the radius of the centerline of the bend would be 50 inches.
A 3D bend is a pipe bend that the bend radius is 3 times the pipe outside diameter.

To calculate the degrees per meter required to bend a 16" pipe to a 10D bend, you would first need to determine the bend radius using the formula: Bend Radius = Pipe Diameter x Bend Factor. For a 10D bend, the bend factor is 10 (D = diameter) so the bend radius would be 16 x 10 = 160 inches. To find the degrees per meter, you would then calculate the angle of the bend (usually 90 degrees for a standard 10D bend) divided by the total length of the bend in meters (which would be the circumference of the bend radius).
To determine short radius and long radius bends, you can refer to industry standards or specifications such as those provided by ASME B16.9 for pipe fittings. A short radius bend typically has a centerline radius equal to the nominal pipe diameter, while a long radius bend has a centerline radius that is 1.5 times the nominal pipe diameter. You can also measure bends in existing piping systems or consult manufacturers’ catalogs for specific dimensions.
Bending a pipe in a required radius of circle by without applying any external source of heat on the pipe is cold bend in pipeline.
To maintain the same center-to-center spread of pipes after a 45-degree bend, you can use the formula: C = L + R, where C is the center-to-center distance, L is the length of the straight pipe sections before and after the bend, and R is the radius of the bend. The radius should be measured from the centerline of the pipe, and adjustments may need to be made based on the pipe diameter and bend radius to achieve the desired spread.
A bend in a 150mm sewer pipe can typically be placed between manholes at locations where the pipe needs to change direction, such as at a junction or to navigate around obstacles. It's important to ensure that the bend adheres to local regulations and standards for sewer installations, which often specify the minimum radius for bends to prevent blockages. Additionally, the bend should be easily accessible for maintenance and inspection purposes.
To calculate a 1.5 bend radius, multiply the diameter of the pipe or conduit by 1.5. For example, if the pipe diameter is 2 inches, the bend radius would be 2 inches × 1.5 = 3 inches. This radius is often used in applications to ensure that bending does not compromise the integrity or flow capacity of the piping system. Make sure to consider the material and type of bend when applying this calculation.
4 times the diameter of the cable
It depends on the cable. 0 to 5000 volts the minimum bending radius is 6 x diameter of the cable. Above 5000 volts the minimum bending radius is 8 x the diameter of the cable.
