Maintenance and Care Recommendations (Engineer’s Advice)
Based on 22 years of supporting oilfield maintenance teams, our senior engineers share practical tips to extend the life of your parts and avoid costly mistakes: 1. Inspect the 2A28824 LONG CROSSOVERS threads every 300 operating hours—clean them with a wire brush to remove dirt and debris, and apply anti-seize compound to prevent thread galling. A common mistake is reusing damaged threads, which leads to leaks and connection failures (complying with API 6A PSL 2 inspection requirements). 2. Check the 1A18614C Clapper Check for debris buildup every 200 operating hours—clean the clapper and seat to ensure proper closing, as debris can prevent the valve from sealing and cause backflow. 3. Inspect the Dustproof seat SFZ1310-22 and O-Ring side door FZ897.1.3.00 every 400 operating hours—replace them if they show signs of wear or cracking, and store spare seals in a dry, temperature-controlled area to avoid damage. 4. Lubricate the Thrust bushing SFZ1310-21 every 500 operating hours with API-approved lubricant to prevent seizing—avoid using generic lubricants, as they break down in high-vibration environments. 5. Store swivels (2A17920, 2A17953) and safety irons in a dry area—apply rust-proof oil to threads when storing spare parts. Never overtighten hammer unions (2P19342) or bolts, as this can damage threads and cause leaks.
