3D Pipe Bend

3D Pipe Bend

Pipe bends are unique parts of piping components. There are pipes, fittings, flanges, and other components in piping. The bends are fittings that are used to connect piping parts together. The bends differ in diameter and radius. The radius is denoted by the letter D and a 3D Pipe Bend means the radius of the bend is 3 times the diameter of the pipe. There are 1.5D bends, 2.5D bends, and so on. An En 10253-2-typ A 3D Bend denotes the standard it belongs to and the type of bend and the radius of the bend. The 3D bends are considered long radius bends. There are short-radius pipe bends as well.

3D radius bend manufacturing process

3D return bends

3D mandrel bends

3D hot induction bend

A 3D pipe bend is produced using a bending machine that heats the pipes to a specific temperature and then uses mechanical force to transform them

  1. Insert the straight pipe into 3D pipe bending machine
  2. Heat the pipe and use lever to bend the pipe
  3. Small pipe bend could be manufactured by cold forming

Surface treatment for 3D pipe bending

  • 3PE coated
  • Black paint
  • FBE coated
  • Galvanized

Find here buttweld 3d bend dimensions as per ASME b16.9, forming process and weight calculation formula of long radius 3d bend

Carbon Steel 3D Pipe Bending processes are facilitated by machines. The machines are mostly operated by manpower. However, there are machines that run with pneumatic power or hydraulic power. The bends can be formed by press bending, hot-slab sand packing forming, three-roll push bending, rotary draw bending, or heat induction bending. Stainless Steel 3D Pipe Bends can be made by either of these methods. The heat induction method uses an induction coil that heats up a piece of pipe and then pressure is applied to bend the pipe to the desired curvature. After the desired shape is achieved, the newly formed bend is then passed through water or cold air for stabilization.

3D Short Radius Bend and long radius bends are used in different applications such as wiring conduits, pipelines, plumbing, handrails, art projects, fencing, automotive exhaust systems, structural frames, and furniture design. The diameter of the bends varies according to the application. The 3D Pipeline Bends can be of smaller diameters below 10 inches or larger diameters above 10 inches. Since these are long radius bends, they can be used in applications where a smooth flow of fluids is needed.

The bend has bend allowance, bend deduction, and K factor in the calculations. Most 90 Degree 3D Bend types have equal legs or equal lengths of pipe on both sides of the curvature. Then the circumference of the pipe bend is measured from end to end of the bending part. The radius of a 90 Deg 3D Bend is denoted by R = C/2(pi) where the C is the circumference of the bend and the pi is a constant, 3.14.

The weight of any piping product involves the volume of the material and density of the material. So the 3D Short Radius Bend or any other bend can be measured for the thickness and total surface. The thickness multiplied by the total surface provides the volume of the material. The piping material has a specific density. Multiplying the volume by the density will give you the weight. The formula is w = 0.0433 ( D – T ) TRθ / 100000 + L where w is the weight in kg, D is the outer diameter of the pipe, T is the thickness in mm, R is the bend radius, θ is the bend angle and L is the sum of double sides straight length.

As discussed earlier, pipe bending is facilitated by machines. A pipe bending machine takes in the raw pipe and makes it into a bend. This is done by pressure, heat, and pulling or pushing of particular parts. Carbon Steel 3D Pipe Bending of smaller diameter pipes could be done with just rotary draw with mandrels placed inside the pipe. The pipe end is bent while the mandrel inside maintains the internal diameter of the pipe. Larger pipe sizes are bent through machines with heating and pressing mechanisms.
