Section bending, alsao called profile bending, is done in a wide variety of metals in various ways.
Two factors, wall factor, and bend radius are used to determine the severity of a bend. little or no support is needed inside the tube when the tube diameter is small and the wall is thick.
As the tube diameter increases, the tube becomes weaker. If the wall thickness of the tube decreases this too makes it weaker. The forces acting on the tube also become greater as the bend centerline radius becomes smaller.
Induction bending of square tube What is Induction Bending? Induction Bending is a precisely controlled and efficient piping bending technique. Local heating using high-frequency induced electrical power is applied during the induction bending process. Pipes, tubes, and even structural shapes (channels,… Read More »Nine steps of the square tube induction bending process
There are five typical methods of bending in the industry: roll bending, incremental bending, hot bending, rotary-draw bending, and induction bending. Each method has its advantages. Some methods are more commonly used in the steel construction industry, while others are… Read More »Five typical methods of profile bending in industry
It’s worth a mention firstly that there are two common terms used in industry, tube bending and pipe bending. Tube is measured by the outside diameter whereas pipe is measured by the inside diameter. Pipe sizing refers to the nominal inside diameter, sometimes called nominal bore, rather than the actual inside diameter.
To determine if a steel section can be curved you need to first determine its section modulus and then see if you have the correct bending equipment.

To understand the mechanics of sheet metal bending, an understanding of the material properties, characteristics and behaviors of metal, is necessary. Particularly important is the topic of elastic and plastic deformation of metal. Information on the properties of metals, with… Read More »Mechanics Of Sheet Metal Bending
The pressure of the supercritical CO2 fluid extraction process is generally 8~35Mpa, sometimes higher. In GB1501998 “Steel Pressure Vessels”, the design specifications are unified for pressure vessels with a design pressure of less than 35Mpa. CO2 extraction vessel is high-pressure… Read More »CO2 extraction vessel materials and the top two structural forms
In the previous article (Three Causes Of Vibration And Noise In Shell And Tube Heat Exchangers), we described: Shell and tube heat exchangers are widely used in industrial carbon dioxide extraction machines. With the expansion of the production scale of… Read More »How to prevent shell and tube heat exchanger from vibrating
Many bends in one cycle Multi-radius bending is commonly used for complex parts when one continuous pipe or tube requires two or more center line radii. Multi-Radius steel bending can be accomplished within the same part, saving customers splices and… Read More »The basics of multi-radius bending in pipe or tube bending
Even when you have chosen standard tube dimensions, and standard bend radii and kept to a limited number of different bend sizes, there are still bend configurations that will cause problems for tube manipulators and will often translate into higher… Read More »Three special cases in pipe/tubing bending
