What Is the Difference Between Hose, Tube and Pipe?

Pipe, tube, and hose are essential components used in various industries for the transportation of fluids, gases, and solids. Although they may share similarities in their cylindrical shapes, they differ in terms of construction, purpose, and specific applications.

A hose is reinforced where a tube is not. Hoses are typically used for applications that involve high pressure, whereas a tube is more often used for lower pressure applications.

  • Pipe is designated by Trade Size, aka nominal diameter (roughly according to its Inside Diameter). Pipe is not normally Flexible.
  • Tubing is designated by actual Outside Diameter. Tubing may be either Flexible or Rigid.
  • Hose is designated by its actual Inside Diameter. The hose is not normally Rigid.

Hoses are generally reinforced. Typical reinforcements include embedded braids or wires, stiffer materials, dual walls, or heavier walls. The hose is typically used for high-pressure applications, while unreinforced tubing is usually used for gravity flow or lower pressure applications.

Hoses: Hoses are the jack of all trades. They can be the stopgap in a wide range of situations. While tubes and pipes have fairly specific uses, hoses have a multitude of applications and follow a wide range of standards. They also are made up of different materials from tubes and pipes. Hoses are typically flexible, made of nylon, rubbers, and other non-metal-based materials, and are not used for pipeline applications.

Tubes: Tubes are used for structural applications. That means they don’t have to be cylindrical. They come in squares, rectangles, and even custom shapes, and oval hollow sections that are used for pressure equipment, mechanical applications, and for instrumentation systems. Tubes are indicated with the outer diameter and wall thickness, in inches or in millimeters.

Pipes: Pipe is a hollow section with round cross-section for the conveyance of products. The products include fluids, gas, pellets, powders, and more. While tubes are used for structural purposes, pipes carry fluids or gases in pipe systems.

The most important dimensions for a pipe is the outer diameter (OD) together with the wall thickness (WT). OD minus 2 times WT (schedule) determines the inside diameter (ID) of a pipe, which determines the liquid capacity of the pipe.

Differences in Materials and the Manufacturing Process

Hoses are manufactured from a completely different material—rubber or PTFE—than tubes and pipes—carbon steel, stainless steel, alloy steel, etc.—so manufacturing processes differ.

Tubes and pipes share similar manufacturing processes, and they’re usually made up of similar materials. For instance, there are stainless steel pipes as well as steel tubes.

However, the pair have different manufacturing requirements. Tubes have stricter requirements that manufacturers need to account for, including thickness, straightness, and roundness of the cylinder. These requirements lead to a higher degree of testing and inspection on tubing compared to piping products.

While tubes, pipes, and hoses seem like similar products that serve similar functions, a deeper analysis shows otherwise. By reviewing various tube, pipe, and hose applications, sizing terminology, and manufacturing processes, it’s clear that these items serve different purposes.

Key Differences Between Pipe, Tube, and Hose

The primary differences between pipe, tube, and hose lie in their rigidity, dimensions, and flexibility. Pipes are rigid and have standardized dimensions, while tubes have precise dimensions with tighter tolerances. Hoses, on the other hand, are flexible and designed for easy maneuverability.

Additionally, pipes and tubes are commonly used for the transportation of fluids and gases, whereas hoses excel in applications that require flexibility, mobility, and the ability to withstand vibration and bending.

Applications of Pipes, Tubes, and Hoses:

Pipes find extensive applications in various industries. They are commonly used in plumbing systems for water supply, drainage, and gas pipelines. In industrial settings, pipes are utilized for transporting chemicals, oils, and gases. They are also crucial components in infrastructure projects such as water distribution networks and sewage systems.

Tubes are widely used in both structural and non-structural applications. In structural frameworks, tubes serve as load-bearing members in buildings, bridges, and other construction projects. They are also utilized in heat exchangers, condensers, and boilers due to their excellent thermal conductivity. Additionally, tubes are commonly employed in automotive components, such as fuel lines and exhaust systems, as well as instrumentation systems for precise fluid control.

Hoses are versatile components with applications in various industries. In the automotive sector, hoses are used for fuel lines, coolant systems, and air intake systems. In construction and agriculture, hoses are employed for water delivery, irrigation, and hydraulic systems. They are also utilized in manufacturing processes for the transfer of chemicals, solvents, and abrasive materials. Hoses excel in applications where flexibility, mobility, and resistance to bending and vibration are crucial.

Conclusion

In conclusion, pipe, tube, and hose are distinct components with unique characteristics and applications. Pipes are rigid and standardized, tubes are precise and often used in structural and thermal applications, while hoses offer flexibility and mobility. Understanding the differences between these components is crucial for selecting the right one for a given application, and ensuring efficient fluid or gas transportation.
