3-inch rotary drilling hose assembly
In the field of oil drilling and production, the rotary drilling hose assembly is a core component for transporting high-pressure mud, directly determining the safety and efficiency of operations. As a leading enterprise in China's rubber hose industry and a national-level specialized, refined, and new "little giant" enterprise, Letone Technology has created the API 7K 35MPa 3-inch rotary drilling hose assembly (3"×17m, with Fig. 1502 hammer union), which strictly complies with API 7K standards, adapts to various complex drilling scenarios, and is the preferred equipment in the industry.
1. Precise Specifications to Meet Industrial Needs
The nominal diameter of the hose assembly is 3 inches (about 76mm), the total length is 17m, and the rated working pressure is 35MPa (about 5075Psi). Equipped with Fig. 1502 hammer union, it can be directly connected to drilling risers, mud pumps and other equipment, adapting to medium-deep drilling, cementing and other scenarios. The 1502 union adopts a lip-shaped elastomer seal, which is firmly connected with zero leakage, and can withstand high-frequency vibration and high-pressure impact, ensuring stable operation.
2. Multi-layer Structure, Balancing Pressure Resistance and Durability
The hose adopts a scientific multi-layer composite structure: the inner layer is made of synthetic rubber multi-component composite material, which is wear-resistant and corrosion-resistant, can resist mud scouring, and ensure medium purity; the reinforcement layer is precision-wound with multi-layer high-strength ultra-soft steel wire, which disperses high-pressure impact, has both flexibility and pressure resistance, and is easy to lay on site; the outer rubber layer is wear-resistant and weather-resistant rubber, which is UV-resistant and mechanical damage-resistant, adapting to the temperature range of -20℃~+121℃ and extending service life; the hose and union adopt an integrated crimping process with reliable sealing.
3. Severe Working Conditions, Adapting to Complex Scenarios
Designed for harsh drilling environments, the assembly can stably transport water-based and oil-based mud under 35MPa high pressure, tolerate hydrogen sulfide environment, and adapt to operations in different regions such as deserts and oceans. It can absorb high-frequency vibration of equipment to avoid damage and leakage; the 17m length reduces splicing, and the 3-inch inner diameter meets the demand for large flow, balancing efficiency and durability.
4. Letone's Advantages, Highlighting Brand Strength
The product has passed API 7K, API Q1 and other certifications, with full-process quality control; it has a CNAS national-level laboratory and a professional R&D team, providing personalized customization; strict testing and automated production lines ensure product consistency and stable supply, meeting the needs of batch and emergency orders.
5. Comprehensive Services to Escort the Whole Operation Process
Letone provides one-on-one selection guidance, on-site installation and commissioning, 24-hour after-sales maintenance and emergency supply services. Each hose is traceable, helping customers reduce costs and improve efficiency.
In summary, Letone API 7K 35MPa 3-inch rotary drilling hose assembly, with standard compliance, excellent performance and perfect service, has become a reliable choice in the oil drilling and production industry, fulfilling Letone's mission of "making fluid technology benefit hundreds of millions of people".
