Maintenance and Care Recommendations (Engineer’s Advice)

Based on 27 years of supporting oilfield maintenance teams—including those in high-sulfur [4] and low-temperature environments—our senior engineers share practical tips to extend part life and avoid costly mistakes: 1. Inspect the 2A21068 Integral Connections and Pipe every 300 operating hours—clean threads with a wire brush to remove dirt and debris, and apply anti-seize compound to prevent thread galling (a common mistake that leads to connection failure). 2. Lubricate the 2A17170 Swivel every 400 operating hours with API-approved grease (complying with API 16A guidelines) to prevent seizing—avoid generic grease, as it breaks down in high-vibration or saltwater environments. 3. For 2P12009 Hammer Unions, follow maintenance best practices [1]: re-tighten with a pipe wrench if leaks occur, replace密封圈 every 1,800 operating hours, and apply rust-proof oil to threads when storing spare unions to prevent rust. 4. Replace kava tooth plates (W5-7, 2164) every 7,800 drilling hours, or sooner if you notice wear—worn tooth plates reduce drilling efficiency and can damage drill pipes. 5. Calibrate the 2A18138 SPRING RELIEF VALVE every 500 operating hours to ensure accurate pressure relief, complying with API 6AV1 standards—skipping calibration can lead to overpressure damage. 6. Store integral connections and swivels in a dry area—apply rust-proof oil to threads when storing spare parts, especially in saltwater or high-humidity environments. Avoid using generic密封圈 for hammer unions, as they break down in high-pressure environments and cause leaks [1].
