Pipe bending is a crucial process in various industries, including automotive, construction, HVAC, plumbing, and aerospace. It involves shaping pipes and tubes into specific angles or curves to meet the requirements of different applications. This guide covers everything you need to know about pipe bending, including methods, materials, applications, and best practices.
What is Pipe Bending?
Pipe bending is the process of reshaping pipes or tubes into desired angles or curves without compromising their structural integrity. It is used to create custom shapes for fluid transport, structural frameworks, and aesthetic designs.
Types of Pipe Bending Methods
Mandrel Bending
A mandrel (a solid rod) is inserted into the pipe to prevent collapsing or wrinkling during bending.
Ideal for: Thin-walled pipes, precision bends, and tight radii.
Roll Bending
Uses rollers to gradually curve the pipe into large-radius bends.
Ideal for: Spiral pipes, coils, and large-radius curves.
Compression Bending
The pipe is pressed against a die to create a bend.
Ideal for: Thicker pipes and simple bends.
Rotary Draw Bending
A die rotates to pull the pipe around it, creating precise bends.
Ideal for: Complex shapes, tight tolerances, and high-quality finishes.
CNC Pipe Bending
Computer-controlled machines ensure high precision and repeatability.
Ideal for: Mass production, custom designs, and complex geometries.
