- Yield strength.<\/strong> The machinery has to be capable of performing the bend. The required force depends largely on the type of steel and its yield strength.<\/li>\n
- Wall thickness.<\/strong> When bending tubes and pipes, the thickness changes in the inner and outer walls of the bend. The inner wall becomes thicker while the outer wall becomes thinner. Some machines provide support to avoid problems with the cross-section, such as wrinkles in the inner wall. If support is not provided, care must be taken to prevent these changes in thickness from becoming a problem.<\/li>\n
- Bend radius. <\/strong>Suppliers normally provide recommendations for the minimum achievable radius without compromising the integrity of the pipe. It depends on the type of material. Reaching this minimum requires attention and expertise.<\/li>\n<\/ul>\n

- Bend radius vs wall thickness. <\/strong>There is a relation between the minimum bend radius that can be achieved and the thickness of the wall. This is important because the tubes and pipes can fail when the radius is too small compared to the wall thickness.<\/li>\n
- Material elongation value.<\/strong> Elongation can be described as the difference between the yield strength and the ultimate tensile strength of the material<\/a>. A big difference means a big elongation, which results in better formability properties.<\/li>\n<\/ul>\n
Steel Tube Bending<\/strong><\/h2>\n
Steel is one of the most popular metals in the manufacturing industry, with carbon steels and stainless steels<\/a> on the top of the list.<\/p>\n
Carbon steel tubes and pipes are common because of their strength and formability. Also, carbon steel is cheaper, which makes it the right choice when there are no other specific requirements, such as a higher corrosion resistance or demanding operation conditions that may include very high pressures and temperatures.<\/p>\n
Other important properties of this material<\/a> include:<\/p>\n
- \n
- Low melting point.<\/li>\n
- High malleability.<\/li>\n
- High durability.<\/li>\n
- Good heat distribution.<\/li>\n<\/ul>\n
Due to the properties described before, carbon steel pipes are used in many different applications. Examples include conveying low-pressure fluids, machinery, sprinklers, electrical conduits and light gauge steel products, among others.<\/p>\n
On the other hand, stainless steel tubes and pipes are useful in places where corrosion<\/a> is imminent. This material provides great resistance to the unavoidable chemical process.<\/p>\n
