What Is The Meaning Of Stainless Steel Pipe Outer Diameter, Inner Diameter And Nominal Diameter Respectively?

What is the meaning of stainless steel pipe outer diameter, inner diameter and nominal diameter respectively?

1, outer diameter: the diameter of the outer circle of the round stainless steel pipe is called the outer diameter,

2, inner diameter: the diameter of the circular stainless steel inner circle is called the inner diameter,

3. Nominal diameter: also known as average outside diameter; The use of nominal diameter is conducive to the standardization of parts, but also convenient for design, manufacturing, repair and management, reduce manufacturing costs. For stainless steel pipes, the nominal diameter is expressed by a dimension less than the outside diameter and greater than the inside diameter. Corresponding to a nominal diameter of a stainless steel pipe, its outer diameter is a certain value, and the inner diameter changes with the wall thickness.
