Maintenance & Care Recommendations
Proper maintenance of drilling spare parts is critical to extending their service life and ensuring equipment reliability. Below are practical, easy-to-follow guidelines for on-site maintenance:
• Regular Inspection: Conduct visual and functional inspections of all parts every 60-100 working hours. Check for signs of wear (e.g., thread damage, friction material thinning), corrosion, and leakage. Pay special attention to high-wear components like friction discs, brake pads, and O-rings.
• Cleaning & Protection: After use, clean components with neutral detergent to remove drilling fluid, sediment, and debris. Apply anti-corrosion agents (e.g., thread anti-seize, anti-rust coating) to metal parts to prevent corrosion, especially in humid or offshore environments.
• Lubrication: Lubricate moving components (e.g., idle gear shafts, power input shafts, roller shafts) every 60 working hours with high-temperature, high-pressure lubricating grease to reduce friction and wear. Avoid over-lubrication, which can attract dust and debris.
• Timely Replacement: Replace worn or damaged parts before they fail. Key replacement thresholds include: friction disc thickness ≤2mm, brake disc thickness ≤8mm, O-ring cracking or hardening, and thread wear exceeding 0.2mm. Follow the recommended replacement cycle (300-500 working hours) for high-wear components.
• Proper Storage: Store spare parts in a dry, clean, and well-ventilated area. Avoid exposure to direct sunlight, high humidity, and corrosive chemicals. Use protective sleeves or packaging to prevent mechanical damage during storage and transportation.

On-Site Fault Maintenance Cases
Below are 4 real, short on-site fault cases involving our spare parts, demonstrating their reliability and the practical solutions we provide to minimize downtime:
Case 1: High-Pressure Swivel Joint Leakage
A drilling site reported leakage from an EXTRA HIGH PRESSURE (15,000 psi NSCWP) LONG RADIUS SWIVEL JOINT (1515SJ10MXM) during high-pressure mud circulation. Upon inspection, the Viton FKM seal was found to be aged and cracked, caused by prolonged exposure to high-temperature fluid (160℃) exceeding the recommended limit. Solution: Replaced the seal with our high-temperature-resistant Viton FKM seal, adjusted the fluid temperature to ≤150℃, and applied anti-corrosion coating to the joint surface. The joint resumed leak-proof operation, and downtime was controlled within 1.5 hours.
Case 2: Hydraulic Power Tong Brake Failure
An XYQ6B series hydraulic power tong experienced brake failure, unable to clamp drill pipes securely. Inspection revealed that the Z6-46 friction disc’s asbestos-free material was completely worn (thickness ≤1mm), and the Z6-28 brake spring had lost elasticity due to fatigue. Solution: Replaced the friction disc and brake spring with our compatible parts, adjusted the brake clearance, and lubricated the brake steel plate. The tong resumed normal braking performance, avoiding potential drill pipe slippage accidents.
Case 3: Dart Check Valve Backflow
A 1″ Figure 1502 Dart Valve (1DV150200-00) was causing backflow of drilling fluid, reducing circulation efficiency. The issue was traced to a worn stainless steel dart and blocked valve port, caused by impurities in the fluid. Solution: Replaced the dart with our 304 stainless steel dart, cleaned the valve port, and installed a 10μm high-precision filter at the fluid inlet. Backflow was eliminated, and circulation efficiency was restored to 100%.
Case 4: Roller Assembly Jamming
An NJ200-06 series roller assembly (N157-5 upper roller, N157-10 lower roller, N157-7 roller shaft) jammed during operation, causing the drilling system to shut down. The problem was due to insufficient lubrication of the roller shaft and corrosion of the N157-6 sleeve. Solution: Replaced the corroded sleeve, lubricated the roller shaft with high-pressure grease, and cleaned the entire assembly. The roller assembly resumed smooth operation, and the drilling system was back online within 2 hours.
