API Certified High Pressure Rubber Hose for Drilling Operations
Product Use
Application: This cutting-edge fracturing hose is designed for swift connectivity between fracturing wellheads and diversion skids, as well as fracturing trucks and high/low pressure manifolds. It's engineered to inject fluids, including acid or fracturing sands, into wells at high flow rates. This causes the oil-bearing rock to fracture, producing cracks, which remain open thanks to the hose's advanced support. The result? An improved and sustained oil flow, optimizing extraction efficiency.
Hose structure:
(a) Lining layer: Utilizing black polymer synthetic rubber, this layer offers exceptional wear and acid resistance, ensuring robust performance under challenging conditions;
(b) Lining wear warning layer: Crafted with white wear-resistant rubber, this layer acts as a vigilant sentinel, alerting to any wear and tear;
(c) Pressure-bearing skeleton layer: Constructed with high-strength steel wire rope, this layer robustly withstands intense pressures, ensuring durability;
(d) Fire-retardant layer: Made with glass fiber, this layer provides superior fire resistance, enhancing safety;
(e) Outer wear warning layer: The outer layer features red wear-resistant rubber, offering a clear visual indicator for wear detection;
(f) Outer protective layer: Composed of chloroprene rubber, this layer is flame-retardant, wear-resistant, and offers protection against oil, ozone, and UV rays;
(g) Protective sheath: Options for external hose protection include stainless steel armor or a plastic spiral sheath, customizable to meet client specifications;
(h) End joint: Featuring high-strength alloy steel, with versatile end connection forms such as flange, hammer union, API 16A HUB, and Grayloc Hub, ensuring secure connections.
•Transporting medium: Engineered to handle fracturing fluids, fracturing sands, hydrochloric acid, liquid carbon dioxide, and more, catering to diverse operational needs.
• Temperature range: Reliable performance across a temperature spectrum from -30ºC to 100ºC.
Advantages:
1. Streamlines fracturing site layout, enhancing operational efficiency.
2. Swift assembly and disassembly, boosting productivity while slashing operational costs.
3. Provides flexible stress buffering and vibration absorption, offering seamless operation.
4. Minimizes connection points, significantly reducing leakage risks.
5. Enables onsite visual inspection of hose wear, ensuring proactive maintenance.
6. Ensures robust and secure joint connections, with anti-corrosion lining for an extended service lifespan.
