Product Overview

Core Purpose

These spare parts are essential for the normal operation, maintenance, and safety of oilfield drilling equipment, particularly Tianyi top drives and ZJ series drilling rig hydraulic, mechanical, and electrical systems. The 1.14.18.013 Lower pin For Tianyi Top Drive secures critical top drive components, preventing misalignment and detachment caused by high vibration and heavy loads—solving the problem of loose parts that halt drilling operations. The 1.07.14.001 Brake plate provides reliable stopping power for drilling equipment, avoiding brake failure that compromises safety and leads to costly accidents. The 1.06.19.002 Washing pipe circlip For Tianyi Top Drive secures wash pipe components, preventing dislodgment that causes fluid leakage and system inefficiency. The 2.4.02.001 Oil return filter removes contaminants from hydraulic fluid, preventing system clogging and component damage. Every part is designed to address specific operational pain points, keeping your drilling equipment running safely and continuously in harsh oilfield environments, while complying with industry safety and quality standards, and aligning with API Spec 6A’s latest pressure boundary qualification and material traceability requirements.

Function Description

Each spare part serves a unique and vital role in the drilling equipment system. The 1.14.18.013 Lower pin For Tianyi Top Drive features a precision-machined surface with a tolerance of ±0.01 mm, ensuring a tight fit with top drive components—solving the problem of misalignment that causes wear and equipment jamming. The 1.07.14.001 Brake plate has a high-friction surface that delivers consistent stopping power, with a maximum braking torque of 850 N·m, avoiding brake fade and failure in high-load scenarios. The 2.2.08.006 Cartridge valve regulates hydraulic flow with minimal leakage (less than 0.06 ml/min at 210 bar), maintaining system stability and avoiding pressure fluctuations that reduce efficiency. The 4.19.03.27 Air filter traps particles as small as 2 microns, ensuring clean air intake and preventing engine overheating. The 2.4.35.005 Parker Straight Connector creates a leak-free hydraulic connection, withstanding pressures up to 48 MPa, avoiding fluid loss that wastes resources and damages components. All parts work together seamlessly to maintain the integrity, safety, and efficiency of the entire drilling system, ensuring smooth and reliable operation.

Structural Features

Our spare parts are designed with the harsh oilfield environment in mind, boasting structural advantages that outperform standard components. The 1.14.18.013 Lower pin For Tianyi Top Drive is forged from high-strength alloy steel, with a tensile strength of 950 MPa and a hardened surface that resists wear—extending service life to 8,200 working hours, 3,000 hours longer than ordinary lower pins. The 1.07.14.001 Brake plate is made of heat-resistant friction material, with a maximum operating temperature of 350℃, preventing warping and brake fade in high-heat conditions. Fasteners like 4.10.02.104 Hex head bolts and 4.10.08.001 Nut lock washer meet ASTM A 453 Grade 660D requirements, produced in a double-aged condition to meet NACE MR0175/ISO 15156 standards, with a minimum 0.2% offset yield strength of 725 MPa and a Charpy impact test qualification of 40 joules at -196℃. The 2.4.55.012 O-ring is made of high-temperature, oil-resistant rubber, withstanding temperatures up to 130℃ to prevent seal failure, and the 2.4.20.243 High pressure water hose is reinforced with steel wire, with a maximum working pressure of 50 MPa, avoiding bursts in high-pressure systems.

Applicable Working Conditions

These spare parts are widely suitable for various oilfield scenarios, including onshore oilfields (Daqing Oilfield, Shengli Oilfield, Permian Basin), offshore oil platforms (North Sea, Gulf of Mexico), and desert oilfields (Gobi Oilfield, Kazakhstan). They can withstand extreme temperatures ranging from -45℃ to 100℃, adapt to high humidity (up to 98%), high vibration (frequency 12-60 Hz), and high-pressure environments (up to 75 MPa). Whether for deep well drilling (depth up to 7,800 meters), horizontal drilling, or workover operations, our parts maintain stable performance—solving the problem of poor adaptability of ordinary spare parts to harsh conditions. They are fully compatible with Tianyi Top Drive models (DQ50/3150DB, DQ70/4500DB, HDQ70/4500DB, DQ90/6750DB) and ZJ series drilling rigs (ZJ30, ZJ40, ZJ50), eliminating the hassle of finding mismatched components and ensuring quick replacement. This compatibility is critical for reducing downtime, as waiting for mismatched parts can cost thousands of dollars per hour in non-productive time, a key concern for drilling teams operating in remote locations.

Maintenance and Care Recommendations

To extend the service life of our spare parts and ensure equipment safety and stability, our engineers offer practical, on-site maintenance advice. For the 1.14.18.013 Lower pin For Tianyi Top Drive, apply high-temperature lubricant every 200 working hours and check for wear—replace if the pin diameter wears down by more than 0.1 mm, as this can lead to component misalignment. A key engineer tip: never reuse 4.10.17.005 cotter pins or 2.4.99.03.011 Skeleton oil seals, as they lose structural integrity after one use and can cause catastrophic component failure; always verify part compatibility with your equipment’s as-built documentation before installation. For the 1.07.14.001 Brake plate, inspect the friction surface every 300 working hours and replace if the thickness wears below 8 mm. The 2.4.02.001 Oil return filter should be replaced every 450 working hours, and the 2.2.08.006 Cartridge valve should be inspected every 300 working hours for leakage. Never mix different types of bolts (like 4.10.02.104 Hex head bolts and 4.10.02.010 Hexagon bolt), as this can lead to uneven load distribution and component detachment. Our team also provides on-site maintenance training to help your team master these skills and avoid common mistakes, reducing maintenance costs and unplanned downtime.
