Pipe vs Tube
Pipes and tubes are two essential components in various industrial and construction applications, used for transportation of fluids, gases, and solids.
Despite the similarities, pipes and tubes have distinct differences, which determine their suitability for specific applications.
Understanding the difference between pipes and tubes is crucial in selecting the right material for your project, ensuring safety, and avoiding any potential failure.
In this blog post, we will delve into the details of pipes and tubes, exploring their definitions, properties, and applications.
What is a Pipe?
A pipe is a cylindrical hollow that is used to transport fluids, gases, and solids from one location to another. Pipes are usually made from materials such as iron, steel, PVC, and others.

The dimensions of pipes are defined by their Nominal Pipe Size (NPS) and Schedule (wall thickness).
NPS refers to the size of the pipe, while the schedule refers to the wall thickness of the pipe. Pipes are typically round, but can also be square or rectangular.
Pipes are commonly used in plumbing, heating, and cooling systems for the transportation of water, gas, and air.
They can also be used for structural purposes in construction projects. The manufacturing process of pipes usually involves welding or extrusion, depending on the material used.
It’s important to note that pipes have specific pressure ratings, and it’s crucial to choose the right pipe with the right strength and pressure capacity for your application to ensure safety and prevent any potential failure.

What is a Tube?
A tube is a hollow, seamless component with a circular cross-section, and it has three dimensions: the outside diameter (O.D.), the inside diameter (I.D.) and the wall thickness (W.T.), which is specified in inches or fraction of an inch.
Tubes are typically used in applications where precision and accuracy are required, such as in fluid power systems and heat exchangers, and they are known for their ability to maintain flow in applications such as hydraulic systems.
The lack of seams in seamless tubes makes them ideal for use in high-pressure applications where leaks could be catastrophic.
The manufacturing process of tubes usually involves drawing or extrusion, depending on the material used.

Tubing vs Piping: Key Differences
Tubes and pipes are commonly used in various industrial applications, but there are key differences between the two.
- When ordering a tube, the outside diameter and wall thickness are the determining factors, whereas piping is ordered using the Nominal Pipe Size standard, as well as the nominal diameter and schedule number or wall thickness.
- Tubes have the advantage of being telescoped, and they are generally stronger and more durable than pipes.
- While Tubes are always round, pipes can have a variety of shapes, including square and rectangular, in addition to round like a pipe.
- For larger applications, pipes are often a better choice, but for small diameters, tubing is the preferred option.
- On the other hand, tubes are often used in high pressure rating and critical applications.
