Core Purpose & Equipment Adaptation
Our drilling spare parts are precision-engineered and supplied to perfectly match a wide range of critical drilling equipment, including ZJ-40CZ drill rigs (with DQ 225DBZ top-drive hydraulic valves), 13-5/8″ 10K double ram BOPs, TDS-11SA top drives, Engine 2K-350, hydraulic pump systems, IBOP assemblies, and mud pump components. We directly address the unique, on-site pain points of three core user segments—drilling engineering teams, maintenance technicians, and procurement professionals—each relying on our parts to keep operations running safely, efficiently, and without costly interruptions. Drilling engineering teams face the devastating impact of unplanned downtime—halted operations due to failed BOP seals, hydraulic pumps, or top-drive components can cost thousands of dollars per hour, not to mention compliance risks. Maintenance technicians need easy-to-install, durable parts with clear, practical guidance to resolve faults quickly, without specialized tools or extensive training—saving time and reducing labor costs. Procurement professionals struggle with sourcing OEM-compatible parts that meet industry safety standards, avoid ill-fitting components that lead to repeated replacements, and align with tight budget constraints while ensuring compliance with drilling regulations. The core purpose of our products is to eliminate these pain points by providing direct-fit, high-quality replacements for mission-critical components—covering hydraulic systems, BOP seals, top-drive parts, IBOP assemblies, fluid handling components, and fasteners—all designed to withstand the harsh, high-pressure (up to 7500Psi), corrosive conditions of onshore and offshore drilling, reduce operational costs, and ensure continuous, compliant operation.
Product Overview
We offer a comprehensive portfolio of drilling spare parts tailored to the specific needs of ZJ-40CZ drill rigs, 13-5/8″ BOPs, TDS-11SA top drives, and related drilling equipment, with key models including 3″ 7500Psi swivel feed pipe (P/N 30123289), IBOP crank assembly (P/N 98898), ZJ-40CZ top-drive hydraulic valve (P/N 1HK5; RVCA LAN/LH), hydraulic vane pump (P/N 107783-5C11R), and BOP blade seal RS11187.10.05A. Our product range encompasses nine critical categories to cover every on-site need: hydraulic components (pumps, motors, valves, cylinders, hoses), BOP seals (blade seals, top seals, side seals for 13-5/8″ 10K double ram BOPs), top-drive parts (return spring screws, rotating link adapters for TDS-11SA), IBOP assemblies (crank assys, hose assys), fluid handling components (swivel feed pipes, impellers, high-pressure oil pipes), engine parts (for 2K-350 engines), fasteners (screws, pins, lockwire, washers), sealing components (seal rings, seal rods, gaskets), and auxiliary parts (reservoir breathers, liner stabilizers, bearing shields). All parts are manufactured in strict compliance with API Spec 7K (Drilling Equipment for Oil and Gas Wells), API Spec 16A (Wellhead and Christmas Tree Equipment),NACE MR0175 (Sour Service Corrosion Resistance), and IECEX Ex-proof Standards (for electrical components like solenoid valves), using premium materials selected for extreme durability and performance: forged alloy steel for hydraulic cylinders and fasteners, corrosion-resistant stainless steel for high-pressure pipes and swivel feed pipes, high-grade fluorocarbon and nitrile rubber for BOP seals and hydraulic seals, and wear-resistant alloys for impellers and friction-resistant components. Every part is a direct OEM-compatible replacement, engineered to exact dimensions to eliminate on-site modifications, reduce maintenance time, and ensure seamless integration with existing equipment—delivering long service life, reliable performance, and minimized replacement costs.

Corrosion-resistant coatings and sealed components ensure longevity in marine and harsh land environments.
Maintenance & Care Recommendations
Proper maintenance of drilling spare parts is critical to extending service life, reducing replacement costs, and preventing unplanned equipment failure. Below are practical, on-site actionable guidelines—designed for ease of implementation by on-site technicians, with clear steps to keep parts performing reliably:
• Regular Inspection (60-100 Working Hours): Conduct visual and functional checks of all wear-prone parts—inspect BOP seals (RS11187.10.05A, RS11816.07.01.01) for wear or damage; check hydraulic pumps (107783-5C11R) for leaks or abnormal noise; test solenoid valve DHA-0713/PA-M/722DC for proper actuation; inspect swivel feed pipe 30123289 for corrosion or connection leaks; check impellers for vane wear.
• BOP Seal Maintenance: Replace BOP blade seals, top seals, and side seals every 500 working hours (or immediately if leakage is detected) to ensure well control safety; clean BOP ram surfaces before installing new seals to prevent damage; store spare BOP seals in a cool, dry environment to avoid rubber aging.
• Hydraulic System Care: Lubricate hydraulic cylinders (1300127451) and pivot pins (30158766-1) every 100 working hours with high-temperature, high-pressure grease; inspect hydraulic hoses (59024P170024, 59044P170042) for cracks or bulges—replace immediately to prevent burst failures; change hydraulic fluid every 1000 working hours to remove contaminants.
• Top-Drive & IBOP Maintenance: Inspect TDS-11SA return spring screw 109528-4 for fatigue or deformation; lubricate IBOP crank assembly 98898 and rotating link adapter 30173277 regularly; replace IBOP hose assy 59024P170021 if leaks are detected to prevent fluid loss and IBOP malfunction.
• Fluid Handling Component Care: Clean impellers (419835000, 418823000) monthly to remove mud and debris buildup—buildup reduces efficiency and causes premature wear; inspect high-pressure pipes (30113982-500) for corrosion or damage; replace seal rings (91923) and seal rods (72220) if leakage is detected.
• Timely Replacement of Worn Parts: Replace friction-resistant item 1200419584 when wear is visible; replace hydraulic pump 107783-5C11R if flow or pressure is inconsistent; replace shield bearing 30154362 if noise or play is detected; follow OEM replacement intervals for engine parts and BOP components to ensure compliance and safety.
• Proper Storage of Spare Parts: Store all spare parts in a dry, well-ventilated area (relative humidity <60%) away from direct sunlight and drilling fluid/mud. Keep BOP seals and hydraulic seals in sealed packaging to prevent moisture damage; store high-pressure pipes and fasteners in anti-corrosion packaging; store electrical components (solenoid valves) in a dust-free environment.

On-Site Fault Maintenance Cases
Below are 3 real, short on-site drilling rig fault cases—reflecting common issues faced by drilling teams—demonstrating how our direct-fit spare parts resolve critical problems quickly, minimize downtime, and restore operational efficiency:
Case 1: 13-5/8″ BOP Seal Leak & Well Control Risk
A drilling site reported a critical leak from their 13-5/8″ 10K double ram BOP, posing a well control risk. Inspection revealed a worn RS11187.10.05A blade seal and damaged RS11816.07.10.02 side seal—caused by prolonged exposure to drilling fluid and delayed replacement. Solution: Replaced the blade seal and side seal with our OEM-compatible parts, cleaned the BOP ram surfaces, and tested the BOP closure. The leak was eliminated within 1.5 hours, restoring well control safety and preventing a costly rig shutdown.
Case 2: ZJ-40CZ Top-Drive Hydraulic Pump Failure
A ZJ-40CZ drill rig experienced top-drive failure due to a malfunctioning hydraulic vane pump (P/N 107783-5C11R), halting drilling operations. Inspection found that the pump’s vanes were worn, causing reduced fluid flow and pressure. Solution: Replaced the hydraulic vane pump with our direct-fit part, flushed the hydraulic line to remove contaminants, and tested the top-drive operation. The top drive resumed full functionality within 1 hour, minimizing downtime and restoring drilling operations to schedule.
Case 3: TDS-11SA Top-Drive Return Spring Screw Failure
A TDS-11SA top drive experienced erratic operation, with difficulty retracting during drilling cycles. Inspection revealed a fatigued return spring screw (P/N 109528-4)—caused by high torque and lack of regular inspection. Solution: Replaced the return spring screw with our OEM-compatible part, lubricated the top-drive linkage, and tested the retraction function. The top drive resumed smooth, consistent operation within 45 minutes, eliminating operational delays and reducing the risk of further component damage.
