What is the general requirement for pipe support spacing?

The general requirement for pipe support spacing takes into account various critical factors, including the diameter of the pipe, the material it is made from, and the type of fluid it is carrying. This consideration is crucial because different materials and fluid characteristics can affect the weight, thermal expansion, and overall behavior of the piping system under different conditions.

For instance, a larger diameter pipe carrying a heavier fluid requires closer support spacing to ensure structural integrity and prevent sagging or bending. Similarly, the material plays a role; for example, metal pipes may have different support requirements compared to plastic pipes because of their different strength characteristics and susceptibility to environmental factors. Fluid type is also significant, as fluids with varying densities and temperatures may exert different forces on the piping system, influencing how often support must be placed.

Unlike a simplified approach based on arbitrary measurements or the pipe's length alone, the actual supporting needs must be based on the comprehensive characteristics of the application. Therefore, adhering to a specified guideline that varies based on these factors ensures safety and compliance with industry standards.
