What is the difference between average and minimum wall tubing?

The terms “average wall” and “minimum wall” refer to two different ways of specifying the thickness of tubing.

Average wall tubing refers to tubing that has a uniform thickness along its entire length. The thickness of the wall is determined by taking the average of several measurements taken at various points along the length of the tubing. This ensures that the tubing has consistent strength and performance properties throughout its entire length.

Minimum wall tubing, on the other hand, refers to tubing that has a specified minimum thickness, but may have variations in thickness along its length. This can result in areas of the tubing that are weaker or stronger than others, depending on the thickness of the wall at that point.

The choice between average wall and minimum wall tubing depends on the specific application and requirements of the tubing. In some cases, a minimum wall thickness may be required to ensure that the tubing can withstand the pressure or stresses it will be subjected to. In other cases, a more consistent thickness may be preferred to ensure that the tubing has consistent properties throughout its length.
