People always confused about how to describe steel pipe dimensions (sizes) in correct ways, or how to clarify to seller what exactly pipe size we are going to purchase. In case any misunderstandings or a different size we purchased, that will be a big trouble.
So, what are the exactly right ways to express the steel pipe dimensions?
For your better understanding, we will explain from below aspects:

Pipe Size Schedule (Schedule 40 & 80 steel pipe means)
Means of Nominal Pipe Size (NPS) and Nominal Diameter (DN)
Steel Pipe Dimension Chart (Size chart)

Steel Pipe Dimension 3 characters
A completely description for steel pipe dimension includes outer diameter (OD), wall thickness (WT), pipe length (Normally 20 ft 6 meter, or 40 ft 12 meters).
Through these characters we could calculate the pipe weight, how much pressure pipe could bear, and the cost per foot or per meter.
Therefore, that’s why we always need to know a right pipe size.
