Pneumatics, Hydraulics - Tubing, Hose, Piping

1. Overview

Tubing, hose, and piping systems are critical components in pneumatic and hydraulic systems, enabling the transmission of fluids (compressed air, gases, or liquids) to power machinery and control processes. These systems form the backbone of industrial automation by ensuring precise energy transfer, motion control, and operational efficiency. Their importance spans industries such as manufacturing, energy, transportation, and aerospace, where reliability and performance under extreme conditions are paramount.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
Hard Tubing (Metal/Plastic)	Rigid, high-pressure resistance, corrosion-resistant materials (e.g., stainless steel, copper)	Fixed installations in factories, hydraulic power units
Flexible Hose	Multi-layer construction with reinforcement (e.g., rubber, thermoplastic with braided fibers/wires)	Mobile equipment (excavators), robotic arms with dynamic movement
Piping Systems	Larger diameter, welded/flanged connections, designed for bulk fluid/gas transfer	Petrochemical plants, pneumatic conveying systems
Vacuum Tubing	Smooth inner surfaces, low outgassing materials (e.g., PTFE, stainless steel)	Semiconductor manufacturing, vacuum pumps

3. Structure and Composition

Typical components include:

Inner Layer: Smooth bore material (rubber, thermoplastic, or metal) for media compatibility
Reinforcement Layer: Braided/woven fibers, spiral-wound wires, or helical steel for pressure resistance
Outer Cover: Abrasion-resistant, UV/corrosion-protective coating (synthetic rubber, polymer)
Connectors: Threaded, flanged, or quick-disconnect fittings (materials: brass, stainless steel, plastic)

4. Key Technical Specifications

Parameter	Importance
Working Pressure (psi/bar)	Determines system safety and performance limits
Temperature Range ( C)	Ensures material stability under thermal stress
Material Compatibility	Prevents degradation from fluids, chemicals, or environmental exposure
Inner Diameter (ID)/Outer Diameter (OD)	Affects flow rate and system efficiency
Bend Radius	Dictates installation flexibility and fatigue resistance

5. Application Fields

Manufacturing: CNC machine tool hydraulic systems, robotic grippers
Energy: Offshore drilling hydraulic control lines, wind turbine pitch systems
Transportation: Railway brake systems, aircraft landing gear hydraulics
Medical: Pneumatic surgical tools, laboratory automation equipment

Case Study: In automotive assembly lines, reinforced rubber hoses enable 6-axis robot arms to operate at 150 psi with 10,000+ cycle durability.

6. Leading Manufacturers and Products

Manufacturer	Representative Products
Parker Hannifin	Parflex hydraulic hoses, stainless steel tubing for aerospace
Emerson (ASCO)	Numatics pneumatic tubing systems for food processing
Igus	Chainflex hybrid hoses for robotic applications
Festo	Modular piping systems for factory automation

7. Selection Recommendations

Evaluate operating pressure vs. burst pressure (safety factor 4:1)
Consider fluid compatibility (e.g., synthetic hydraulic oil vs. aggressive chemicals)
Assess environmental factors: vibration, abrasion, outdoor UV exposure
Optimize diameter to minimize pressure drop (<3 ft/sec velocity for hydraulics)
Select connectors with appropriate sealing technology (NPT, BSP, O-ring face seal)

Industry Trends Analysis

Key developments include:

Material Innovation: Growth of thermoplastic elastomers (TPEs) replacing rubber for lighter weight and longer life
Smart Integration: Embedded sensors in hoses for real-time pressure/leak monitoring
Miniaturization: Micro-tubing solutions for compact medical and lab-on-chip devices
Sustainability: Biodegradable hydraulic fluids driving demand for eco-friendly polymer linings
Standardization: Increasing adoption of ISO 17165-2 for high-pressure hydraulic hose testing
