The Difference Between Aluminum Pipe and Tube - 1

 

The Difference Between Aluminum Pipe and Tube

Pipe and Tube may be two terms for hollow cylinders, but they are not the same. In some cases, the two terms can be used interchangeably. However, there are some differences between aluminum pipe and tube, especially in the ordering method and tolerance of materials.

We will help you to understand the differences between pipe and tube in detail from shape, size, application and other aspects. If you still have some questions, you can consult Teda. With our rich production and sales experience and complete product inventory, we can solve all problems related to pipe and tube for you.

The definition of aluminum pipe and aluminum tube

Aluminum pipe

Aluminum pipes are classified as tubular vessels used in pipelines and piping systems, which are usually used to transport gases and fluids. They are specified by the Nominal Pipe Size (NPS) and Schedule (Wall Thickness).

Generally, pipe refers to a hollow cylinder made of metal or other materials used to transport water, gas, steam, oil, etc.

Aluminum tube

Aluminum tubes are usually used in structural engineering, and the outer diameter is an important and accurate figure. OD and WT (wall thickness) specify the pipe size. Aluminum tubes have many characteristics, such as the weight is light and it is more easily to accept paint and other decorations.

In general, tube is a hollow aluminum cylinder, especially used to transport or contain liquid or gas.

The difference between aluminum pipe and tube

	Aluminum Pipe	Aluminum Tube
Shape	circle	circle, rectangle, square, oval
Key dimensions	The most important dimensions are outer diameter (OD) and wall thickness (WT). OD－2×WT (SCHEDULE) determines the inner diameter (ID) of the pipe, which is the liquid capacity of the pipe.	The most important dimensions are outer diameter (OD) and wall thickness (WT). These parameters, expressed in inches or millimeters, represent the true dimension value of the hollow section.
Wall thickness	The thickness of aluminum tubes is specified by the "Schedule" value (the most common ones are Sch. 40, Sch. STD, Sch. XS, and Sch. XXS). Two pipes of different NPSs with the same schedule have different wall thicknesses (In inches or millimeters).	The thickness of aluminum tubes is specified by the "Schedule" value (the most common ones are Sch. 40, Sch. STD, Sch. XS, and Sch. XXS). Two pipes of different NPS and the same specification have different wall thicknesses (in inches or millimeters).
Measure	Measured by nominal outside diameter (also known as NPS or nominal pipe size) and wall thickness.	It is measured by accurate outer diameter (OD) and wall thickness. Generally with more stringent tolerances and specifications.
Scalability		Tube can be scaled.
Rigidity	Pipe is rigid and cannot be formed without special equipment.	It can be shaped through some efforts. The tubing will not be excessively deformed, wrinkled or broken when bent and coiled.
Strength	Pipe is less powerful than tube.	Stronger for applications requiring durability and strength.
Processing method	Hot rolled only.	Cold rolled and hot rolled.
Application	Pipe is the rated pressure used to transport fluid or gas pipe is suitable for larger applications.	Tube is used for structural applications. Usually used where small diameters are required.

Difference in shape, size and structure between aluminum pipe and tube

Pipe is always round. It cannot be formed easily without using special equipment. Pipes are usually seamless and pressure rated to avoid leakage, as they usually carry liquids or gases. The size of the pipe is usually larger than the pipe. Pipes are suitable for larger applications ranging in size from half an inch to a few feet.

Tube can be rectangular, square, or circular. They are usually seam welded. Tubes are typically used for applications requiring smaller diameters.
