Product ID: 80070311 – HP Tube, 60K, 3/8 in.

Description:
This component is a high-pressure (HP) seamless tube manufactured from corrosion-resistant stainless steel, designed for ultra-high pressure (UHP) waterjet cutting systems . The .38 designation indicates a 3/8 inch outer diameter (OD), which is the industry standard for medium to high-flow waterjet plumbing . The tube is rated for continuous operation at 60,000 PSI (approximately 4,137 bar) and is intended to safely transport pressurized water from the intensifier pump to the cutting head assembly .

Applications:

Used as the primary rigid or semi-rigid conduit to convey high-pressure water from the pump outlet to the cutting head swivel, Z-axis, or bridge
Suitable for use as custom-cut interconnect tubing between system components such as the intensifier, accumulator, and dump valve
Intended for integration into 60KSI (60,000 PSI) waterjet systems, compatible with KMT, Flow, OMAX, BFT, WSI, and TechniJet equipment

Features:

High-Strength Material: Manufactured from high-grade stainless steel (e.g., 316L/316 or equivalent), offering high tensile strength and resistance to corrosion and fatigue .
Precision Manufacturing: Features a smooth internal bore surface finish, which minimizes pressure loss and ensures consistent water flow .
Standardized Dimensions: The 3/8 inch outer diameter ensures compatibility with standard 60K fittings, collars, and gland nuts .
Fatigue Resistance: Engineered with mechanical properties (e.g., autofrettage treatment) to withstand continuous pressure cycling from zero to maximum operating pressure without premature failure .

Maintenance:

Inspection: Regularly inspect the external surface for signs of vibration wear (fretting), pitting, corrosion, or cracking. Pay close attention to areas near clamps and connections .
Handling: Care must be taken not to dent, kink, or scratch the tube surface during installation or maintenance, as surface defects can become stress risers leading to failure.
End Preparation: Ensure tube ends are properly cut, squared, and de-burred before installing cone fittings to ensure a reliable metal-to-metal seal.
Support and Clamping: Use appropriate high-pressure clamps (e.g., Clamp Pair 1-13144) to secure the tubing and dampen vibration. Improper support can lead to fatigue failure .
Replacement Criteria: Replace the tube if any deep scratches, cracks, deformation, or severe corrosion is found. Do not attempt to repair or straighten a damaged HP tube.
Full Depressurization: Always fully depressurize the waterjet system (both hydraulic and high-pressure water circuits) and follow lockout/tagout procedures before removing or installing the HP tube.
