What does the term 'bending radius' refer to?

The term 'bending radius' specifically refers to the minimum curve allowed for a pipe to prevent damage and maintain flow integrity. This is crucial because when pipes are bent, especially in pressure piping systems, they must be treated with care to avoid stresses that could lead to kinks or fractures. A bending radius that is too tight can cause significant issues such as reduced flow capacity, increased pressure drops, or even complete failure of the piping system.

Understanding the proper bending radius for different pipe materials is essential in ensuring that the integrity of the piping is preserved, thereby allowing fluids to flow smoothly without obstruction or leakage. Proper adherence to the minimum bending radius not only protects the material of the pipe but also ensures compliance with industry standards and safety protocols. This is why recognizing the bending radius is critical in piping design and installation practices.
