High-pressure tubes

Tube, pipe, fittings and flanges

Seamless high-pressure tubes for a variety of high-pressure applications using liquid or gas as the pressure medium, such as hydraulic installations, test benches and water-jet cutting equipment.

High-pressure tubes

High-pressure tubes from Alleima are characterized by high yield strength and high tensile strength in combination with high elongation. The pressure resistance is guaranteed by the very smooth inside surface. An autofrettage treatment prolongs the cycle fatigue behavior.
