Product Overview

Product Introduction

The spare parts we supply cover key components of oilfield equipment, including locking parts, hydraulic components, transmission parts, sealing parts, and connecting parts. Key products include: Lock washer LW-0375-IT (used for locking nuts and preventing loosening), Washer FW-0375-A (for load distribution and vibration reduction), Hydraulic cylinder DT10715 (core executive component of hydraulic systems), Gear DT10678 (for power transmission), Hydraulic Directional Valve H10053 (controlling hydraulic oil flow direction), and Seal kit S08-1038-010 (preventing oil leakage). All parts are made of high-quality materials—such as high-strength alloy steel for fasteners, corrosion-resistant stainless steel for hydraulic components, and high-temperature resistant rubber for sealing parts—to ensure adaptability to harsh oilfield environments.

Function Description

Each spare part is designed to target specific functional needs, solving practical pain points in oilfield operations: Lock washer LW-0375-IT uses a W-type structure to lock nuts in key positions of equipment, preventing loosening caused by long-term vibration, which often leads to equipment failure and safety hazards; Hydraulic cylinder DT10715 converts hydraulic energy into linear reciprocating mechanical energy, with stable output force to drive the movement of drilling and fracturing equipment, solving the problem of insufficient thrust and slow response of ordinary hydraulic cylinders; Gear DT10678 adopts precision gear hobbing technology, ensuring smooth power transmission, reducing energy loss, and avoiding equipment jamming caused by gear wear; O-ring S01-1264-01N has good sealing performance, preventing hydraulic oil leakage, which is a common fault in oilfield hydraulic systems.

Structural Features

Our spare parts have obvious structural advantages to adapt to oilfield working conditions: Lock washer LW-0375-IT has a simple and reliable structure, easy to install and disassemble, and each lock piece can be accurately bent into the nut groove to ensure firm locking, which is more stable than ordinary flat washers; Hydraulic cylinder DT10715 adopts a double-seal structure, with a labyrinth ring DT10995 and O-ring combination, effectively preventing oil leakage and extending service life; Gear DT10678 has a modular structure, with a tooth surface hardness of HRC 58-62, strong wear resistance, and easy replacement; Fitting ELL 90°, MALE 1/2 JIC, MALE 3/8 ORB H15-070220-08-06 has a precision thread design, ensuring tight connection, no leakage, and strong compatibility with different pipeline specifications.

Applicable Working Conditions

These spare parts are widely applicable to various oilfield working conditions, including onshore oil wells, offshore drilling platforms, fracturing sites, and well maintenance operations. They can adapt to extreme temperatures ranging from -40℃ to 120℃, resist corrosion from crude oil, mud, and saltwater, and withstand high pressure up to 40MPa and high vibration up to 20Hz. Whether it is the dusty environment of onshore drilling rigs, the humid and corrosive environment of offshore platforms, or the high-load working environment of fracturing trucks, our spare parts can maintain stable performance, ensuring the normal operation of equipment.

Maintenance Suggestions

To extend the service life of spare parts and reduce maintenance costs, our engineers provide practical maintenance suggestions based on on-site experience: For locking parts such as LW-0375-IT and FW-0375-A, check the locking status every 200 working hours, and replace them with new ones if there is any deformation or wear (do not reuse old lock washers, as this will reduce locking reliability); For hydraulic components such as DT10715 and H10053, regularly check the hydraulic oil cleanliness, keep it at NAS 8 level or above, and replace the hydraulic oil every 1,500 working hours to avoid oil pollution causing component wear; For sealing parts such as S01-1264-01N and S08-1038-010, check for aging and damage every 300 working hours, and replace them in time to prevent oil leakage; For transmission parts such as DT10678 and M10058, add lubricating oil every 500 working hours, using L-CKD220 heavy-duty gear oil to ensure smooth operation. Avoid using inferior substitutes, as this will greatly reduce the service life of parts and even damage the main equipment.
