English Translation of Title:
Flat Washer 38 – High-Pressure Piping 1-Liter Attenuator – Waterjet Cutting Equipment Accessory

Description, Purpose, Features, and Maintenance:

This component is a precision flat washer sized for 38‑mm high‑pressure piping systems, used in conjunction with a 1‑liter pulsation attenuator within waterjet cutting equipment. It serves as a sealing and load‑distribution interface between flanged connections or threaded couplings operating at ultra‑high pressures.

Purpose:

• Provides a uniform bearing surface beneath fastener heads or nuts in high‑pressure pipe joints.

• Prevents galling and surface damage on attenuator mounting faces during torque application.

• Compensates for minor misalignments and distributes clamping force evenly across the sealing area.

• Assists in maintaining leak‑tight integrity of the attenuator connection under cyclic pressure spikes.

Features:

• Manufactured from hardened, corrosion‑resistant stainless steel to withstand waterjet abrasion and chemical additives.

• Precision ground flatness within tight tolerances ensures consistent sealing compression.

• Smooth, burr‑free edges eliminate stress risers that could initiate cracking in adjacent piping.

• Dimensionally stable across a wide temperature range (‑20°C to +120°C).

• Compatible with both metallic and non‑metallic sealing gaskets used in attenuator assemblies.

Maintenance:

• Inspect for surface pitting, scoring, or thickness reduction before each attenuator rebuild.

• Replace if flatness deviation exceeds 0.05 mm or if corrosion marks are visible on bearing faces.

• Clean with non‑abrasive solvent to remove mineral deposits and abrasive grit; do not use wire brushes that may scratch the surface.

• Always install new washers when replacing attenuator seals or after any high‑pressure leak event.

• Store in a clean, dry container with anti‑rust paper to preserve surface finish.
