Pipe Bend & Pigabble Bend Manufacturers – Long Bend with Radius-R = 3D, 5D & 10D | 3D Elbow, 5D Elbow, 6D Elbow, 8D Elbow, 10D Elbow Manufacturers, Suppliers

  • Steel pipe bends are similar with elbows to some extent, they have same angle degree, thickness and size. The only difference is the pipe bending radius. Pipe elbow has LR (1.5D) & SR (1D) only. While bends R≥3D (R= 3D, 4D, 5D, 6D, 7D, 8D, 9D, 10D) D means outside diameter. Its advantage is that it can match long distance transition requirements, so bend dimensions are commonly designed according to customer requirements. Manufacturing a pipe bend consist of various processes such as bending, squeezing, pressing, forging, machining and more. Metallica specializes in manufacturing long radius bends with Bending radius(R): R=3D, 5D, 6D, 7D, 8D, 10D and 12D, with Bending angle (θ):15°, 30°, 45°, 60°, 90°, 135°, 180°.

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 or equal to 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. Accordingly, if the bend radius is 3D, 5D, 6D, 7D, 8D, 10D and 12D they the fittings are called pipe bends.

What is the Weight Calculation Formula for Pipe Bends?

Weight in kgs = 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
