English Translation of Title:
High-Pressure Bent Tube for High-Pressure Piping – 38 mm, 1-Liter Attenuator, Water Jet Cutting Machine Parts, Model No. 72154075-HP-Tube-Bent-38-High-Pressure-Piping-1-Liter-Attenuator.833.3-1

Introduction, Application, Features, and Maintenance:

This component is a high-pressure bent tube designed for water jet cutting systems, featuring a 38 mm nominal size and intended for use with a 1‑liter attenuator. It combines a pre‑formed rigid tube with pressure pulsation damping to smooth high‑pressure flow and route fluid between components in the machine’s hydraulic circuit.

Application:
Used to connect high‑pressure components while allowing directional changes and simultaneously dampening pressure pulsations generated by the pump. Typical installations include connections between the pump and attenuator, or between the attenuator and downstream components where vibration isolation and pressure smoothing are required.

Features:

• Rated for extreme pressures common in water jet cutting, up to 6,000 bar (87,000 psi).

• Pre‑formed bends eliminate the need for additional angled fittings, reducing potential leak points.

• Integrated 1‑liter attenuator volume absorbs and smooths pressure pulsations for stable cutting performance.

• Manufactured from high‑strength, corrosion‑resistant material suitable for high‑velocity water and abrasive slurry.

• Combines two functions (directional routing and pressure damping) in a single assembly, reducing component count.

• Helps protect downstream components from pressure spikes and fatigue.

Maintenance:

• Regularly inspect the entire tube length, including bends, for signs of erosion, cracking, pitting, or external damage.

• Check the attenuator section for signs of erosion or pressure loss.

• Monitor cutting performance; pressure fluctuations may indicate internal attenuator damage.

• Replace the tube immediately if any wall thinning, cracking, or leakage is detected.

• Ensure proper tube supports and clamps are in place to prevent excessive vibration.

• Clean internal bore before installation to prevent debris from damaging downstream components.

• Follow specified torque values for all connections.
