High Pressure Tubing Supply, Fabrication, and Installation in the UAE
High pressure tubing is heavy-wall, pressure-rated tubing engineered to transport fluids and gases safely at extreme pressures, typically from 15,000 psi up to 40,000 psi and beyond. It is used in hydraulic power systems, test rigs, chemical injection, and drilling and wellhead applications where standard tubing would fail.
As a high pressure tubing supplier in the UAE, Tensor provides seamless heavy-wall and hydraulic tubing for oil and gas and industrial projects across Abu Dhabi, Dubai, and the wider Middle East. This guide covers pressure ratings, materials, fittings, and what to check before you buy.
What Is High Pressure Tubing?
High pressure tubing is defined by its ability to contain high internal pressure safely, achieved through heavy wall thickness, high-strength material, and seamless construction. Unlike thin-wall precision tubing, it prioritises mechanical strength and fatigue resistance. For small-bore precision measurement and signal lines, see our guide to instrumentation tubing.
What Pressure Ranges and Applications Does It Cover?
High pressure tubing serves the most demanding fluid-power and process duties:
- Hydraulic power units and high-pressure hydraulic circuits.
- Test rigs and pressure-testing systems.
- Chemical injection lines on production facilities.
- Drilling and wellhead high-pressure service.
Working pressures commonly range from 15,000 to 40,000 psi, with some applications demanding even higher ratings.
What Materials Are Used for High Pressure Tubing?
Material selection balances strength, corrosion resistance, and service environment:
- Carbon steel: high strength for many hydraulic and pressure applications.
- Stainless steel: corrosion resistance for harsher media.
- Alloy steels: for elevated strength and fatigue performance.
For sour (H₂S) service, the material must comply with NACE MR0175 / ISO 15156, with controlled hardness to resist sulfide stress cracking.
How Is the Pressure Rating Determined?
The safe working pressure of a tube is set by its outside diameter, wall thickness, and material strength, with a safety factor applied. Heavier walls and higher-strength materials raise the rating. This is the key difference from thin-wall instrumentation tubing: high pressure tubing trades bore size for wall thickness to carry pressure. Always confirm the rated working pressure against your maximum system pressure, including surge and fatigue cycles.
Why Is Seamless Construction Important?
Seamless tubing has no weld seam, which removes the most likely failure point under high pressure and cyclic loading. For this reason, seamless high pressure tube is the standard for high-psi service, offering consistent wall thickness and superior fatigue resistance.
What Fittings and Connections Are Used?
High pressure tubing uses fittings engineered for the same pressure class, including:
- High pressure tube fittings with reinforced ferrules or cone-and-thread connections.
- Hammer-union or threaded end connections for drilling and high-pressure lines.
- Leak-proof joints that hold under vibration, impulse, and pressure cycling.
Match the fitting pressure rating, material, and end connection to the tube and the system.
What Should Be on Your High Pressure Tubing Buyer’s Checklist?
When evaluating a high pressure tubing supplier in the UAE, confirm:
- Rated working pressure against your maximum system pressure.
- Material grade and suitability for the media and temperature.
- NACE MR0175 compliance for sour service.
- Seamless construction and relevant ASTM/API specification.
- Mill test certificates (EN 10204 3.1) and hardness data.
- Fatigue rating for cyclic applications, plus stock and lead time.

FAQs
High pressure tubing is heavy-wall, pressure-rated tubing built to transport fluids and gases safely at extreme pressures, commonly from 15,000 to 40,000 psi and higher. It is used in hydraulic systems, test rigs, chemical injection, and drilling applications.
High pressure tubing uses heavy walls and high-strength material to carry extreme pressure, while instrumentation tubing is thin-wall, small-bore tubing built for precision measurement and signal lines. They serve different duties and are not interchangeable.
Carbon steel, stainless steel, and alloy steels are all used depending on strength, corrosion resistance, and the service environment. For sour (H₂S) service, the material must comply with NACE MR0175 with controlled hardness.
Seamless tubing has no weld seam, removing the most common failure point under high pressure and cyclic loading. It provides consistent wall thickness and superior fatigue resistance, making it the standard for high-psi service.
The safe working pressure depends on the tube’s outside diameter, wall thickness, and material strength, with a safety factor applied. Heavier walls and stronger materials increase the rating. Always confirm the rating exceeds your maximum system pressure, including surge and fatigue.
