3. 产品描述（正文，英文）

• Material & Durability:
  • Constructed from 304 stainless steel (ASTM A249), offering excellent corrosion resistance and 200MPa tensile strength to withstand mechanical stress during transportation and operation. The 5μm electrolytic chrome plating enhances wear resistance, validated through 72-hour salt spray testing (ASTM B117) .
  • Unlike carbon steel pipes, 304 stainless steel maintains structural integrity in humid underground mines, preventing rust-induced blockages or leaks .
• Functional Design:
  • BSPT 1″ threaded connection (ISO 7-1) with a nitrile rubber gasket ensures a secure seal with oil tanks, minimizing spillage. The 90° bend (10x OD radius) allows flexible routing in tight engine compartments, compatible with most rock drill jumbo models .
  • Precision manufacturing (±0.05mm concentricity) ensures smooth oil flow, preventing cavitation and ensuring efficient refueling .
• Environmental Performance:
  • Operates reliably from -40°C (cold underground mines) to +120°C (high-temperature engine bays), with no degradation in material properties. It is resistant to mineral oil, diesel, and common hydraulic fluids, ensuring compatibility with standard mining lubricants .

• Rock Drill Jumbos: Essential for oil refueling in drill arm hydraulic systems and engine compartments.
• Mining Equipment: Compatible with loaders, excavators, and tunneling machines requiring durable oil filler pipes.
• Industrial Machinery: Suitable for heavy-duty diesel engines in construction and quarrying equipment.
