Differentiating Metal Pipe & Metal Tubing

To many, steel and aluminum metal pipe and tube products may seem relatively similar; in many ways, they are. However, significant differences separate the two, including unique applications, features, and benefits. If you’re unsure if a metal pipe or tube is right for your project, several differentiating factors will help with the decision-making process.

What is Metal Pipe?

Round tubular metal pipe is primarily designed to transport fluids and gases. It is designated by a nominal pipe size (NPS or DN) representing a rough indication of the pipe conveyance capacity (flow-carrying capacity). Metal pipe can also be described as having a hollow section with round cross sections. Metal pipe is often measured in outer diameter (OD) and wall thickness (WT). Metal pipe is often used to transfer the following products:

Fluids
Gas
Powders
Pellets

What is Metal Tube?

Metal tube often refers to round, square, oval, and rectangular sections used for providing structural support, where the measurement of its outside diameter is important in how it is used. Metal tubes can often have more specific sizes and tolerances than pipes and can be manufactured into custom sizes. The outside diameter (OD) and wall thickness define the tube.

What are the Differences Between Metal Tube & Pipe?

With the naked eye, there are seemingly few differences between metal pipe and tube products. However, the differences are unmistakable to those working within industries that regularly use metal pipe and tube.
The main difference between metal pipe and tube is the way the diameter of the pipe or tube is designated. Pipe is typically defined by a ‘Nominal Pipe Size’ (NPS) based upon the ID (inside diameter) of the most common wall thickness. At the same time, the tube is designated by the measured OD (outside diameter). Tubes are typically cut flat on the ends, while pipes usually have a slight bevel on the stops to make them easier to mount fittings.

How are Pipes & Tubes Classified?

Tubular metal products are generally classified as either pipe or tube. However, these two classifications are often divided into subclassifications. Examples of subclassifications of both metal pipe and tube include the following:

Metal Pipe Subclassifications

Standard pipe
Line pipe
Water well pipe
Pressure pipe

Metal Tube Subclassifications

Pressure tube
Structural tube
Mechanical tube
