Whether you're building a hydraulic press system for a manufacturing line, powering heavy machinery in a mining operation, or engineering fluid control for offshore drilling, one component connects it all—Hydraulic Tubes. These rigid tubes carry high-pressure fluid with precision, strength, and longevity. Without them, the entire hydraulic ecosystem would collapse.

While hoses are known for flexibility, Hydraulic Tubes are prized for stability, accuracy, and durability under constant load. In this blog, we’ll explore why choosing the right hydraulic tubing is crucial, what materials and standards matter, and why Inflex Hydraulics remains the go-to source in the UAE for top-grade hydraulic tubes.

What Are Hydraulic Tubes?

Hydraulic tubes are rigid cylindrical components used in hydraulic systems to transport fluid between pumps, valves, actuators, and other components. Unlike hoses, which are flexible and used in dynamic or moving applications, tubes are ideal for static installations requiring high precision, minimal expansion, and leak-proof fluid delivery.

They are typically made of high-strength steel or stainless steel, with smooth internal surfaces that reduce friction, prevent flow turbulence, and maintain pressure integrity over long distances.

Why Tubes Over Hoses in Certain Applications?

You might wonder—why use tubes when hoses exist?

Here’s why engineers prefer Hydraulic Tubes in specific scenarios:

✅ Dimensional Accuracy

Tubes provide exact lengths, consistent diameters, and fixed paths—critical in CNC machines, robotic arms, and aerospace assemblies.

✅ Zero Expansion

Hoses expand slightly under pressure, which can affect timing and performance. Tubes remain dimensionally stable under pressure.

✅ Long Lifespan

Tubes typically outlast hoses because they are not subjected to flex fatigue.

✅ Neat Routing

In systems where aesthetics or safety matter (like aircraft or cleanroom installations), tubes ensure an organized layout.

✅ Vibration Resistance

Paired with proper clamps and mounts, tubes handle vibration better in many static environments.

That said, tubes and hoses often work together. Inflex Hydraulics offers both and helps clients decide the best balance based on system dynamics.

TL;DR

Hydraulic Tubes are high-strength, rigid fluid conductors used in hydraulic systems where precision, pressure retention, and long-term durability are required. Inflex Hydraulics offers top-grade tubes in carbon steel and stainless steel, cut and prepared to exact project requirements.

Applications of Hydraulic Tubes

From powering excavators to controlling jet landing gear, hydraulic tubing is everywhere. Some of the top sectors where Inflex Hydraulics supplies and supports tubing include:

• Oil & Gas: Wellhead control systems, offshore rigs
  
  

• Marine: Steering, deck lifts, and ballast control
  
  

• Industrial Manufacturing: Presses, injection molding, metal forming
  
  

• Aerospace: Hydraulic actuators in aircraft landing systems
  
  

• Construction Equipment: Lifts, diggers, and concrete pumps
  
  

• Defense: Tank turrets, armored vehicle suspension
  
  

• Power Plants: Valve control systems, turbine pitch control
  
  

• Food & Pharma: Stainless steel tubing in hygienic hydraulic systems
  
  

Each industry has its own set of challenges—temperature, vibration, corrosion, and pressure range. That’s why material and design selection is key.

What Materials Are Used in Hydraulic Tubes?

Inflex Hydraulics offers a wide variety of Hydraulic Tubes tailored to each use-case:

1. Carbon Steel Tubes (DIN 2391-C, ST37.4, ST52.4)

• Economical
  
  

• High pressure ratings
  
  

• Suitable for general industrial use
  
  

• Requires surface treatment (zinc coating, phosphating)
  
  

2. Stainless Steel Tubes (SS304 / SS316)

• High corrosion resistance
  
  

• Used in marine, food, and chemical environments
  
  

• Clean inner bore, ideal for sensitive fluid transfer
  
  

3. Seamless Tubes vs. Welded Tubes

• Seamless: Higher strength and pressure capacity
  
  

• Welded: Cost-effective for less demanding systems
  
  

Inflex stocks all major standards and sizes, from small OD tubing (6mm, 10mm, 12mm) to heavy-duty 50mm+ diameters.

Performance Standards to Look For

Reputable tube suppliers must meet global hydraulic standards. Inflex Hydraulics offers tubing that adheres to:

• DIN 2391 / DIN EN 10305-1 (Europe)
  
  

• ASTM A269 / A213 / A511 (USA)
  
  

• ISO 8434 (International Fitting Compatibility)
  
  

• SAE J524 / J525 (Hydraulic line tubing)
  
  

Each length is tested for tensile strength, surface quality, dimensional tolerance, and cleanliness.

Installation: What Makes Tubing Work Well?

To get the most out of your tubing system, attention to detail during installation is vital. Inflex Hydraulics supports clients with the following:

• Tube Bending: Using CNC benders for exact radius curves
  
  

• Cutting & Deburring: Clean cuts with burr-free edges
  
  

• Flaring & Fitting Prep: For leak-proof joints with 37° or 45° flares
  
  

• Surface Coating: To prevent corrosion and extend service life
  
  

• On-site Assembly: Support with layout, clamping, and safety checks
  
  

Whether you need ready-to-install pre-bent tubing or raw stock for fabrication, Inflex delivers.

Real-World Success: How Inflex Helped a Solar Plant in Abu Dhabi

A renewable energy firm building a large solar-thermal plant in Abu Dhabi needed hydraulic tubes for its actuator control system. Their previous vendor caused multiple project delays due to inconsistencies in dimensions and surface corrosion.

Inflex Hydraulics stepped in.

• Delivered over 3000 meters of DIN 2391 seamless carbon steel tubes
  
  

• All tubes phosphated and sealed for desert environment protection
  
  

• Pre-cut and bent to CAD layout
  
  

• Delivered 3 weeks before project milestone
  
  

• Zero rejection on quality check
  
  

The result? The solar plant met commissioning dates and has since expanded its contract with Inflex for future projects.
