The 56.520.00 brake strap (TQ340-35Y hydraulic tongs) provides reliable braking force, with a friction coefficient of 0.45, ensuring stable casing makeup/breakout and avoiding slipping that could damage drill pipes. The 325-14-0 4 bore washpipe (7500 PSI) withstands high pressure, delivering drilling fluid to the drill bit smoothly, preventing blockages and ensuring drilling efficiency.

Structural Features

All spare parts adopt high-quality materials and optimized structural design to withstand the harsh oilfield environment—including high pressure, high vibration, corrosive fluids, and extreme temperatures: The 110103-500 upper IBOP assembly is made of high-strength alloy steel, heat-treated to HRC 38-42, with a precision-machined interface, service life of 7500+ working hours, and pressure resistance of 15K PSI. The G3766-1A impeller housing (Mission Fluid King) is cast iron with a wear-resistant slurry lining, thickness of 12mm, service life of 6200+ working hours, and compatibility with 1-1/8in pump cases. The 40×3.1 GB 1235 O-ring seal uses nitrile rubber (NBR) with a shore hardness of 70±5, tensile strength of 18MPa, service life of 2500+ working hours, and excellent sealing performance under high pressure. The 56.520.00 brake strap (TQ340-35Y) is made of high-temperature resistant friction material, with a steel core for reinforcement, service life of 3800+ working hours, and resistance to oil and abrasion. The 4G154836 bearing (180×280×219) is a cylindrical roller bearing with a double row design, dynamic load rating of 1200kN, service life of 6000+ working hours, and ability to withstand heavy loads in high-vibration environments.

Applicable Working Conditions

Our spare parts are widely applicable to various harsh oilfield working conditions, including onshore and offshore drilling platforms, high-temperature and high-pressure (HPHT) oil wells, sour service environments, and desert oilfields with high sand concentrations: The 110103-500 upper IBOP assembly (15K PSI) is suitable for wellhead operations in HPHT wells, with pressure up to 15K PSI and temperature -29℃ to 121℃, complying with API 16A standards. The G3766-1A impeller housing (Mission Fluid King) is suitable for slurry-lined cooling pumps in desert oilfields, with sand concentrations up to 220g/L and temperature -30℃ to 100℃. The 40×3.1 GB 1235 O-ring seal (PPG 2FZ35-35 BOP) adapts to BOP operations in offshore and onshore wells, with pressure up to 35MPa and temperature -29℃ to 121℃, suitable for drilling mud and oil media. The 56.520.00 brake strap (TQ340-35Y) is suitable for hydraulic tongs in high-torque casing operations, with torque up to 3500 N·m and temperature -20℃ to 80℃. The 325-14-0 washpipe (7500 PSI) is suitable for high-pressure drilling operations, with pressure up to 7500 PSI and temperature -20℃ to 120℃.

Maintenance & Practical Tips

Based on years of on-site maintenance experience, our engineers provide practical, easy-to-follow tips to maximize the service life of our spare parts and avoid common pitfalls that lead to premature failure: For the 110103-500 upper IBOP assembly, inspect the relief valve every 300 working hours to ensure it opens at the correct pressure (15K PSI); clean the valve seat to remove debris, as blockages can cause pressure buildup. For the G3766-1A impeller housing (Mission Fluid King), inspect the slurry lining every 400 working hours; replace if the lining thickness is reduced by more than 3mm, as this can expose the cast iron and cause impeller damage. For the 40×3.1 GB 1235 O-ring seal (PPG 2FZ35-35), store in a cool, dry place away from UV light to prevent aging; apply a thin layer of high-temperature grease during installation to avoid tearing, and replace every 6 months or if leakage is detected. For 56.520.00 brake straps (TQ340-35Y), inspect for wear every 200 working hours; replace if the friction material thickness is less than 5mm, as this reduces braking force and causes slipping. For 325-14-0 washpipes, flush with clean water after each use to remove mud buildup; inspect for corrosion or cracks, and replace if any damage is found. Engineer’s Reminder: Never mix parts from different manufacturers, especially for PPG 2FZ35-35 BOP, TQ340-35Y hydraulic tongs, and Mission Fluid King pumps, as mismatched tolerances can cause accelerated wear and equipment damage. Always use parts that comply with API 16A, API 6A, and GB standards to ensure performance and safety—critical for meeting the industry’s strict requirements.
