What is ultra high pressure stainless steel tubing?

High pressure tubing has 40% higher tensile strength than the annealed tubings. They are manufactured with strict adherence to the specifications for ensuring tolerance and bore quality. The high pressure tubing 60,000 psi is found in very high pressure services like in water cannons for cutting metals. These tubes can be made from different grades of ss and each offer some exclusive properties. There are flexible tubing which are used as moving parts of dynamic systems.

The Stainless Steel Pressure Tubes are available with different surface finishes, which make them suitable for aircraft industrial, and various other high-end applications. The High Pressure Stainless Tubing is also found in various hydraulic systems for exerting pressure on components like lifts and jacks. They are also used in heavy machinery like mining and earth-moving equipment due to the high strength.

Advantages of high pressure SS tubing

  • The 150K SS 304 High Pressure tubing is widely used as fluid handling components. The tubes are found for various applications in industries like petrochemical, chemical, oil and gas, etc.
  • They can resist internal & external pressures, along with shock and vibration.
  • They offer effective protection against different types of corrosion.
  • They have greater carrying capacity and less chance of breakage.
  • They possess high strength and are non-brittle at lower temperature conditions.
  • The 60K High Pressure Stainless Tubing has low maintenance, good service life.
