Function Description

Each spare part is designed to address specific on-site challenges, ensuring reliable performance under extreme oilfield conditions. Here’s how our key parts solve common pain points:

• Well Control Components (2FZ35-35 Ram with Seal, IBOP Valves): The 5″ Ram with Seal (ф 127 mm) for 2FZ35-35 BOP can withstand 35MPa working pressure, preventing well blowout risks by ensuring tight sealing; the Upper IBOP Valve Assembly 30173887-500 and LOWER IBOP 114706-500 provide quick shutoff, solving valve sticking and leakage issues.

• ZQ203-100 Tongs Parts: The Roller Jaw 01.01-11M (d=100 MM) withstands 100KN.m torque, ensuring smooth make-up and breakout operations; the ZQ203-245 brake band provides reliable braking, shortening brake response time by 1.2 seconds and solving brake slack problems.

• Sealing & Bearing Components: Oil Seal PD38*56*12 (HG4-692-67) uses nitrile rubber, with a working temperature range of -40℃ to 220℃ and a leakage rate of less than 3ml/h, solving oil leakage in rotating shafts; Bearing 22236CC/W33 (GB/T288-1994) reduces vibration by 1.8mm/s, extending transmission system service life by 12 months.

• Hydraulic Fittings & Pumps: Angle Fitting 56502-16-16S and ELL 90° H15-520220-04-04 ensure leak-free hydraulic connections, with a pressure rating of 35MPa; Hydraulic pump 117603-1 delivers a stable flow rate of 110L/min, solving pressure fluctuations and pump failure issues.

Structural Features

Our spare parts are built with high-quality materials and precision manufacturing, designed to withstand the harshest oilfield environments while being easy to install and maintain. Key structural features include:

• Durable Material Selection: Critical components like ZQ203-100 Roller Jaw and 2FZ35-35 Ram are made of 42CrMo alloy steel (HRC 49-53), ensuring wear and impact resistance; seals and O-rings (51300-223-F, PD38*56*12) use nitrile rubber and PTFE, resisting crude oil, seawater, and chemical corrosion.

• Precision Machining: All parts are processed by CNC precision machine tools with a machining accuracy of ±0.004mm, ensuring perfect fit with original equipment. Threaded fittings (56502-16-16S, 53219-1) meet 6H precision standards, preventing leakage from thread mismatch.

• Extreme Environment Adaptability: Parts like the air bag BOMCO KB-75 and Oil Seal PD38*56*12 withstand temperatures from -45℃ to 130℃; the 2FZ35-35 Ram with Seal resists high pressure up to 70MPa (static hydraulic test pressure), suitable for high-pressure well control scenarios.

• Easy Installation & Maintenance: Optimized for on-site operations— the Bush bearing 2P100108 for SPM TWS-600S pump can be replaced without disassembling the entire pump, reducing maintenance time by 50%; the ZQ203-245 brake band uses a quick-attach design, simplifying replacement.

Applicable Working Conditions

Our spare parts are engineered to perform reliably in the most challenging oilfield environments, solving the problem of poor adaptability of ordinary parts:

• High-Pressure Well Control Scenarios: Suitable for wells with working pressure up to 35MPa (5,000psi), such as the 2FZ35-35 BOP parts and IBOP valves, ensuring safe well control even in high-pressure conditions.

• Onshore & Offshore Drilling: Resistant to high humidity, salt spray, and corrosive media— the Angle Fitting 56502-16-16S and air bag BOMCO KB-75 maintain performance in offshore environments, preventing corrosion and leakage.

• Low-Temperature Frozen Oilfields: Adapt to temperatures as low as -45℃— the Oil Seal PD38*56*12 (HG4-692-67) and ZQ203-100 Roller Jaw start without jamming, ensuring stable operation in cold regions.

• High-Dust & High-Impact Sites: Desert and open-pit oilfields benefit from the winch rope stopper DSQ-01.00 and Shaft Sleeve 32SB180J0008J, which prevent dust intrusion and withstand impact, reducing equipment wear.

Maintenance and Care Suggestions

Based on decades of on-site experience, our engineers share practical maintenance tips to extend part life, reduce costs, and avoid common mistakes (engineer’s实操 advice and pit avoidance reminders):

• Well Control Components (2FZ35-35 Ram, IBOP Valves): Inspect the Ram seal every 2 months; replace if there’s any sign of wear or damage. Test the IBOP valve operation monthly to ensure quick shutoff— avoid using excessive force when operating the valve, as this can damage the seal and valve stem.

• ZQ203-100 Tongs Parts: Lubricate the Roller Jaw 01.01-11M with No. 2 lithium-based grease every 4 months; check the brake band tension regularly. If the brake band wear exceeds 0.5mm, replace it immediately to prevent brake failure.

• Seals & Bearings: Replace Oil Seal PD38*56*12 every 18 months; store spare seals in a sealed container away from sunlight and moisture. For Bearing 22236CC/W33, check for vibration and noise every 3 months— add lubricant if needed, and replace if vibration exceeds 3mm/s.

• Hydraulic Fittings & Pumps: Inspect hydraulic fittings (56502-16-16S, J10900A-20) for leaks every month; tighten loose fittings with a torque wrench (40-45 N·m) to avoid over-tightening, which can damage threads. Replace the Hydraulic pump 117603-1 filter every 6 months to prevent debris from damaging the pump.
