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.
