Knowing the definitions and differences in characteristics between the tubes, hoses, and pipes is important in order to select the right one for a particular application or situation. A hose, tube, and pipe can almost be used interchangeably, but they do have characteristics that differ.
- Tube: A hollow cylinder typically made out of plastic or metal that is used to transport liquids or gases
- Hose: A flexible tube that is typically made out of plastic or metal that is used to transport liquids or However, it can also be rigid
- Pipe: A rigid tube that is made out of plastic or metal that is used to transport liquids or Pipes are more often than not very flexible
Criteria on selection
When selecting a tube or hose, the three main criteria are length, diameter, and material. Knowing your application criteria and media allows you to properly select these three components of your tube or hose. Incorrectly specifying a hose or tube could lead to a burst or failure causing leakage and system downtime.
In order to avoid unnecessary pressure drops, it is quite important to keep the length of the hose or tube to a minimum, while also exceeding the threshold that is required to avoid tension. The length should be specified at the maximum length of all movements.
When sizing a hose or tube, the inside diameter needs to be specified as this will affect the flow capacity and flow speed. It is often a balance between optimizing the transfer of energy and lowering costs. However, undersized hoses can lead to a large performance loss and an oversized hose can lead to a lack of space.
A hose or tubes material needs to withstand the environment temperature, media temperature, and pressure It also needs to be flexible, or rigid enough, for installation as it may need to bend around obstacles.
