General Details

Steel pipe bend is a pipe fittings which used to change direction of the pipeline for some specific reason. The manufacturing are cold and hot heating. While Bending pipe in the heating process, the heating process should be slow and uniform, so as to ensure the thermal conductivity of the pipe, we should pay attention to avoid overheating and carburizing.

What is Industrial Processes for Bend Pipe Fittings?

Bending, squeezing, pressing, forging, machining and more.

Steel Pipe Bend Dimensions

Steel Pipe Bend Dimensions

Bending Radius

R≥3D (R= 3D, 4D, 5D, 6D, 7D, 8D, 9D, 10D) D means outside diameter.

What is Bend Angle?

Normally 15°, 30°, 45°, 60°, 90°, 135°, 180° or at customer’s option.

Straight Length (L) for Bend

Normally between 300mm and 1500mm in length of straight. It is also at customer’s option.

Application of Buttweld Elbow & Bend

Buttweld elbows & bends are widely used in many industries, such as power generation, petroleum, natural gas, chemicals, shipbuilding, heating, paper-making, metallurgy and so on.

Weight formula of Bend Pipe Fittings

Weight / kg = 0.0433 ( D – T ) TRθ / 100000 + L

D = Outside diameter

T = Thickness in mm

R = Bend radius

θ = Bend angle

L = Weight of double sides straight length

What is Difference between Pipe Elbow and Bend?

Pipe bends typically have a minimum bending radius of 1.5 times pipe radius (R). If this bending radius is less than 1.5R, it is called Elbow. For example, 1.5D elbow we call it as long radius ( LR) elbow and 1D elbow as short radius ( SR) elbow.
