What is the Difference Between Tubing and Pipe?  

Without the proper background knowledge, it can be difficult to know how to distinguish between a piece of tubing and pipe. Both are hollow, cut at similar lengths and sizes, typically fabricated from steel, and serve various industrial-grade purposes. The key-differences between these products relate to their shape, measurement designations, and intended applications. MB Metals is your premier stocking supplier of ASTM-standard steel tubing and pipe products. Our expansive warehouse in Kent, WA stocks a variety of tubing and pipe products for our customers in the Western United States. We utilize a robust network of domestic and international milling partners to provide the best quality, selection, and affordability possible. To help aid new buyers in selecting the correct piece of tubing or pipe, here are some key-differentiators that set these two products apart.

Steel Pipe

Steel pipe is a cylindrical, hollow piece used for the conveyance of gases, liquids, pellets, powders, and in a wide variety of construction and building applications. A specific Nominal Pipe Size (NPS) designates the different sizes for steel pipe. This number represents an estimation of the pipe’s conveyance capacity. We offer ASTM A53 schedule 10, 40, and 80 pipes, along with specialty sections to meet your exact needs.

Steel Tubing

Also hollow and fabricated from steel, tubing can come in round, oval, square, and rectangular configurations, depending on the unique application needs. Sizing for Tubing is designated by the outer diameter dimensions, and the wall thickness—which are both measured in inches or millimeters. MB Metals offers ASTM A500 Grade A, B and C square, rectangular and round hollow sections, and ASTM A513 square and rectangular hollow sections for an array of application needs.
