Together these two downloads are a powerful tool. The Tube Bending Formulas Guide that is bundled with the calculator covers some of the most common tube bending formulas, including tube inside diameter, wall factor, mandrel nose, radius, and clamp length. What is in the Tube Bending Formulas Guide? Some of the most common shapes covered by the calculator are: It then calculates the section area moment of inertia properties of common shapes. The tube bending section modulus calculator allows you to input the tube specifications into an easy to use calculator. What shapes are covered in the calculator download? We’ve created a tube bending calculator and tube bending formulas guide to help you navigate all of the calculations, variables, and prep work. There are a lot of calculations and variables involved in tube bending. Where can you find help with these calculations? As long as the round material number is higher than the non-round material, then that particular bender will be capable of bending your part shape. How do you know what bender will bend your square, rectangle, non-round shape? You need to calculate the section area moment of inertia for the round material and compare it to your non-round material. What happens if you are not bending round tubes? Much better to avoid these problems altogether by taking a bit more time planning your bend and performing calculations. Performing a bend incorrectly can lead to tube bulging, tube collapse, and other tube problems. This is important because knowing if a bend will work before you perform it increases your efficiency, saves time, and saves material. Also, the material composition determines the deforming of the tubing material past the given material’s modulus of elasticity and into the yield strength of the material.ĭetermining the section modulus of the piece of tube or pipe you need to bend is important because it will allow you to know before you bend if your equipment can successfully complete the bend. When bending tube or pipe, the bender must have enough bend arm toque to overcome a material’s section modulus to make a bend into the tube that is permanent. However, section modulus can also relate to bending tubes. Typically, structural engineers designing “I” beams or T beams calculate section modulus of the cross-sectional area of the beam to understand if the beam will support a particular load or repeated cyclic loading. This is so that building, bridges, and rail road tracks do not fail and have safety factors. In particular, calculating the section area moment of inertia properties of common shapes for tube bending can be time-consuming and complicated. If you’ve ever had to perform the calculations necessary to properly bend tube and pipe you know that while they are a vital part of the bending process, there is often a lot of information to juggle.
