Structural Features

Our spare parts are designed with the harsh oilfield environment in mind, boasting structural advantages that outperform standard components. The 1.03.16.711 Support plate assembly For Tianyi Top Drive is made of high-strength alloy steel, with a tensile strength of 860 MPa, ensuring it can withstand the heavy loads of top drive operations—extending service life to 7,300 working hours, 2,400 hours longer than ordinary support plates. The 2.1.05.003 Lubricating oil pumps TPEC top drive features a corrosion-resistant housing and precision-machined gears, complying with NACE MR0175/ISO 15156 standards for sour service compatibility. Fasteners like 4.10.02.197 Hex head bolts and 4.10.01.045 Hexagon socket head cap screws undergo hot-dip galvanization, resisting rust and corrosion from saltwater and oilfield chemicals, and meet ASTM A 182 requirements. The 2.4.51.062 O-ring and 2.4.55.013 seal ring are made of high-temperature resistant rubber, withstanding temperatures up to 120℃ to prevent seal failure. The 2.4.20.118 High pressure water hose is made of wear-resistant rubber, with a maximum working pressure of 42 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, 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 95℃ (covering API 6A temperature grades from K to V), adapt to high humidity (up to 98%), high vibration (frequency 12-58 Hz), and high-pressure environments (up to 70 MPa). Whether for deep well drilling (depth up to 7,200 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 (DQ40, DQ50, DQ70), TPEC Top Drive models (TDC-350, TDC-400), and ZJ series drilling rigs, 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.

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 1.03.16.711 Support plate assembly For Tianyi Top Drive, inspect it for cracks or deformation every 250 working hours, and tighten all mounting bolts to the recommended torque of 85 N·m—this prevents misalignment and extends its service life, a step many teams overlook. A key engineer tip: never reuse worn 2.4.56.010 Rotary oil seals; even minor damage can cause oil leaks that lead to component overheating and failure, and always verify the seal’s compatibility with your equipment’s as-built documentation. For the 2.1.05.003 Lubricating oil pumps TPEC top drive, change the oil filter every 500 working hours, and use only the recommended grade of lubricating oil to avoid pump damage. The 2.3.04.001 Brake should be inspected every 400 working hours, and the brake pads replaced if wear exceeds 3 mm. Never mix different types of fasteners, as this can lead to uneven load distribution and component failure. Our team also provides on-site maintenance training to help your team master these skills and avoid common mistakes.
