Stainless Steel Tubes vs Pipes: What is the Difference?

Stainless steel tubes and pipes look similar but serve different purposes. Tubes are measured by outer diameter and wall thickness, come in round, square, or rectangular shapes, and suit precision applications like instrumentation and heat exchangers. Pipes are always round, sized by Nominal Pipe Size, and built for pressure and fluid transport. Common grades: 304, 316L, 321.
