The bending radius refers to the small radius that the titanium coil pipe must have when bending to prevent cracks, deformation or damage to the pipe during the bending process. In the application of titanium coils, the choice of bending radius is very important because it directly affects the service life and safety of titanium coils.
Generally, the bending radius of titanium coil pipes cannot be less than 3 times the pipe diameter. For larger pipe diameters, the bend radius may be larger. In addition, the bending radius is also affected by other factors, such as the wall thickness of the pipe, bending angle, etc. When selecting the bending radius, these factors need to be taken into consideration to ensure that the titanium coil will not be damaged during the bending process.
In practice, the bend radius is usually determined experimentally. When performing a bending test, the titanium coil needs to be placed on an adjustable bending device and the bending angle and bending radius are gradually increased until it cracks or deforms. By observing the test results, it is possible to determine its maximum tolerable bending radius.
In addition, in order to ensure the safety of titanium coils during the bending process, other aspects of detection and control are also required, such as bending angle, bending speed, cooling method, etc. These factors need to be comprehensively considered based on the specific titanium coil material, specifications and usage environment.
