High-pressure tubes

Tube, pipe, fittings and flanges

Need to withstand extreme pressures while resisting corrosion and managing temperature fluctuations? Look into our range of seamless high-pressure tubes, engineered for a wide variety of high-pressure applications using liquid or gas as the pressure medium.

High-pressure tubes from Alleima are characterized by their high yield and high tensile strength, combined with excellent elongation properties. The smooth interior surfaces ensure superior pressure resistance, while autofrettage treatment enhances fatigue life and improves cycle durability.

Versatile high-pressure applications

We regularly supply high-pressure tubing for hydraulic installations, test benches and waterjet cutting equipment. But their uses extend far beyond these, including:

  • Hydraulic systems (e.g. for aircraft, construction equipment)
  • Chemical processing industries (e.g., for transporting chemicals or gases)
  • Oil and gas exploration (e.g. for drilling equipment)
  • High-pressure steam systems (e.g. in power generation plants)
  • Medical equipment (e.g. for delivering gases)

Overcoming common challenges

  • Corrosion resistance to combat rust and prevent leaks in chemically aggressive environments.
  • Temperature resistance to withstand high and cryogenic temperatures without losing strength.
  • Dimensional precision for critical applications like aerospace or medical use.

High-pressure tube options

Below you will find an overview of our high-pressure tube offering, available in stainless steel and other alloys. Naturally, the grade you choose will depend heavily on your pressure and safety rating requirements and the specific fluid being transported.

Sustainable, fully integrated manufacturing

Our tubes are manufactured and tested in a fully integrated, high-quality process, from melt to final tube, with an emphasis on sustainable production. We adhere to international standards such as ASTM, ASEM, and ISO, as well as industry-specific guidelines.
