TUBING/HOSES
How to Select Pneumatic Tubing?
Based on Routing Method and Operating Conditions
The selection of pneumatic tubing is primarily based on routing method and operating conditions, rather than a comparison of material properties alone.
Pneumatic tubing refers to various types of tubing used in pneumatic systems, including common pneumatic tubing (such as PU tubing, nylon tubing, and LDPE tubing), reinforced hoses, and tubing for different operating conditions. → PU Tubing vs. Nylon Tubing: Selection Criteria and Application Differences
Role of Pneumatic Tubing in Pneumatic Systems
Pneumatic tubing is used to convey compressed air and connect the air source to various actuators.
Tubing may move with equipment during operation or remain in a fixed configuration.
Classification of Pneumatic Tubing
Pneumatic tubing can be classified based on routing method, application, and operating conditions.
By Routing Method
● Dynamic routing
● Fixed or semi-fixed routing
● Retractable routing
By Application
● General equipment pneumatic lines
● Commercial vehicle air brake systems
● Air supply for tools and operations
By Operating Conditions
● Higher working pressure
● Exposure to sparks or heat sources
● Low-temperature or outdoor environments
● Low-pressure fluid transfer
Pneumatic Tubing Classification and Selection Mapping (Routing × Operating Conditions)
Routing method and operating conditions determine tubing selection.
Dynamic routing typically uses PU tubing, while fixed or semi-fixed routing commonly uses nylon tubing. Under conditions such as higher pressure, low temperature, or exposure to sparks and heat sources, tubing is selected based on operating conditions.
Typical selection mapping is shown below:
| Tubing | Routing Method | Operating Conditions |
|---|---|---|
| PU Tubing | Dynamic routing | Frequent bending or movement |
| Nylon Tubing | Fixed or semi-fixed routing | Long-distance and stable conveyance |
| LDPE Tubing | Low-pressure routing | Low-pressure fluid transfer |
| Reinforced PU Air Hose | High-pressure routing | Higher working pressure |
| Hybrid Air Hose | General air routing | Low-temperature or outdoor use |
| Anti-Spark Tubing | Special environment routing | Exposure to sparks or heat sources |
| Coiled Air Hose | Retractable routing | Space-saving and flexible operation |
| Air Brake Tubing | Vehicle-fixed routing | Compliance with relevant standards |
| Coiled Air Brake Hose | Dynamic tractor–trailer connection | Connection between tractor and trailer |
Tubing selection is not determined by a single factor. It should be evaluated based on routing method, working pressure, and operating conditions to align with system requirements.
