English Translation of Title:
Housing, Attenuator Weldment for Water Jet Cutting Machine Parts – Model No. 72162513-Housing-Attenuator-Weldment.1321.3-1

Introduction, Application, Features, and Maintenance:

This component is an attenuator housing weldment designed for ultra‑high‑pressure waterjet cutting systems . It is the main pressure‑retaining body of the attenuator (also called an accumulator), which stores pressurized water to smooth out pressure pulsations generated by the reciprocating intensifier pump .

Application:
Installed in the high‑pressure plumbing of waterjet cutting machines, typically between the intensifier pump and the cutting head. The housing contains and supports the internal volume of pressurized water that buffers pressure spikes and provides a steady flow during pump stroke shifts .

Features:

• Designed for extreme operating pressures up to 90,000 PSI (6,200 bar) .

• Fabricated as a weldment – a heavy‑wall cylindrical body with welded end closures or fittings .

• Manufactured from high‑strength, corrosion‑resistant materials to withstand cyclic fatigue .

• Provides the structural volume (typically 1–2 liters) needed to dampen pulsations and ensure cut quality .

• Engineered with safety features to contain failure modes (e.g., fatigue cracking leading to spray leaks rather than catastrophic rupture) .

Maintenance:

• Periodically inspect the housing for external signs of corrosion, pitting, or cracking .

• Monitor for high‑pressure water leaks around welds, seams, or fittings – a spray leak indicates fatigue and the need for replacement .

• Follow manufacturer-recommended service intervals, as the attenuator is considered a "semi‑wear" part that requires periodic inspection and eventual replacement .

• Always depressurize the system completely before any inspection or disassembly.

• Replace the housing immediately if any structural damage, deformation, or persistent leakage is observed.
