3D Bend

Manufacturer of 3D Bend

A 3D bend in the context of steel fabrication refers to a type of pipe or tube bend that has a radius equal to three times the diameter of the pipe or tube. These bends are used in various industries, including construction, manufacturing, and plumbing, to change the direction of pipes or tubing while maintaining a smooth flow of fluids or gases.
A 3D bend is a bend in which the radius of the curve is equal to 3 times the diameter of the pipe. It is a smoother bend than a 1.5D bend, which looks almost like a regular 90-degree right angle, but it is a sharper bend than a 5D bend, which looks like a smooth arc between two perpendicular pieces.
