Function & Pain Point Solutions

Every accessory we supply is designed to solve the real-world problems oilfield professionals face daily—problems we’ve witnessed firsthand through decades of working alongside drilling and maintenance teams. Here’s how our key products deliver tangible value:

• Hydraulic Components (BMD-400 Cycloid Hydraulic Motor, KHT7625-334 Hand control valve assembly): Eliminate hydraulic system failures that halt operations. Our BMD-400 hydraulic motor delivers stable power output of 400N·m torque, operates smoothly at 1,500 RPM, and lasts 2,200 working hours—far longer than generic motors that typically fail after 600 hours. It’s specifically designed for XQ89/3YC main pliers, ensuring seamless integration and reliable performance in high-pressure scenarios.

• Sealing Components (KHT7625-926 O-Ring 24×2.4, KHT5500-374 Y-ring Y40x50x6.3, YX sealing ring D45): Stop hydraulic fluid leaks, a top cause of power plier downtime. Our O-rings and Y-rings comply with GB/T1235 and GB/T10708.1 standards, made of high-temperature fluorine rubber that withstands 200℃ operating temperature and 24MPa pressure. The Y40x50x6.3 Y-ring features precise dimensional control (±0.25mm) to prevent extrusion and reversal under high pressure, avoiding leak-related shutdowns.

• Transmission Parts (01.02-02M Idler Z=24, KHT7625-156 Small idler gear, Bearing 6006 GB/T276-94): Eliminate gear jams and worn transmission parts that slow down operations. Our idlers and gears are heat-treated to HRC 61-65 hardness, ensuring smooth operation even under 33,000 N·m torque (KHT5500 rated torque). The Bearing 6006 (GB/T276-94) has a 30mm bore diameter, single-row ball construction, and service life of 9,500 working hours, providing reliable radial load support for transmission systems.

• Jaw & Clamping Parts (KHT7625-800 Front Jaw set 7 5/8″, KHT5500-26 Front jaw plate assembly 3 1/2″): Solve the problem of slipping jaws that damage pipe threads and reduce clamping force. Our jaw sets are made of wear-resistant alloy, maintaining a secure grip even after 3,800 make-up/break-out cycles, and are precision-machined to fit KHT8625 and KHT5500 models perfectly—complying with API 7K standards for casing and tubing operations.

Structural Features

Our accessories are built to withstand the harshest oilfield conditions—from dusty onshore rigs to corrosive offshore platforms—with a focus on durability, ease of use, and long service life:

• Material Excellence: Transmission parts (idlers, gears, pin shafts) use high-strength alloy steel, while sealing components use fluorine rubber and nitrile rubber to resist oil, high temperatures, and corrosion. Fasteners like GB/T70.1-2000 Screw M8X20 and KHT5500-235 Bolt 1/2″UNC are made of high-carbon steel, ensuring high tensile strength and fatigue resistance for 12,000+ assembly cycles.

• Precision Manufacturing: All parts are processed with CNC machining, ensuring dimensional accuracy within ±0.008mm—critical for components like KHT5500-267 Pin shaft and KHT7625-362 Bush that require a perfect fit to avoid equipment jams. This precision matches the original equipment’s specifications, eliminating the need for modification during installation, and aligns with API 7K manufacturing standards.

• User-Centric Design: Key parts like KHT7625-593 YG-46 Ball connector and KHT5500-218 YG-61 Right-angle connector are designed for easy installation and maintenance, allowing technicians to replace parts in minutes rather than hours. Hand control valve assemblies (KHT7625-334) feature intuitive operation, reducing human error and ensuring safe, efficient control of hydraulic systems.

Applicable Working Conditions

Our accessories are engineered to perform reliably in the most challenging oilfield environments, meeting the demands of onshore, offshore, and high-torque drilling scenarios—complying with API 7K and SY/T 5074 standards for drilling and workover power tongs:

• Onshore Oilfields: Adapt to extreme temperature ranges of -50℃ to 100℃, resisting dust, sand, and heavy vibration during drilling and workover operations. Ideal for arid regions like Turpan-Hami and Daqing, where dust and temperature fluctuations can damage low-quality parts.

• Offshore Oilfields: Corrosion-resistant materials (including stainless steel fasteners and fluorine rubber seals) prevent damage from saltwater and humid air, ensuring stable performance on offshore platforms like Bohai Bay. Our O-rings and Y-rings are specially treated to resist saltwater corrosion for 2,300 working hours.

• High-Torque & Casing Operations: Suitable for deep well, horizontal well, and casing operations, where power pliers, tongs, and hydraulic motors operate under up to 33,000 N·m torque and 24MPa pressure. Our accessories are compatible with 71 823-S BV-100C Casing Head Tong, ensuring precise make-up and break-out of casing pipes up to 13 3/8″ diameter.

• Continuous Operation: Designed for 24/7 use, our accessories reduce replacement frequency—our bearings and gear shafts can operate continuously for 9,500 working hours, while our seals and hydraulic motors last 1,800 working hours, minimizing downtime for maintenance.

Maintenance & Engineer’s Practical Tips (Avoid Costly Mistakes)

As an oilfield equipment engineer with 20 years of on-site experience, I’ve seen countless equipment failures caused by improper maintenance or using the wrong parts. Here are my practical tips to extend the life of your accessories and keep your equipment running smoothly:

• Hydraulic Motor Care: Inspect XQ89/3YC main pliers cycloid hydraulic motor BMD-400 every 400 working hours. Check for oil leaks and ensure the motor is properly lubricated with ISO VG 460 high-temperature hydraulic oil. Avoid overloading the motor beyond its 400N·m torque rating—this can cause internal damage and shorten its service life.

• Seal Maintenance: Check KHT7625-926 O-Rings (24×2.4), KHT5500-374 Y-rings, and YX sealing ring D45 every 300 working hours. Replace them if you see cracks, hardening, or oil residue—reusing old seals will lead to leaks that can damage hydraulic systems and piston rods. When installing Y-rings, ensure the groove is clean and free of burrs that can scratch the seal lip.

• Bearing & Transmission Care: Apply high-temperature grease (ISO VG 460) to Bearing 6006, 01.02-02M Idler, and KHT7625-156 Small idler gear every 220 working hours. Grease is critical for reducing friction and wear—low lubrication causes excessive heat and premature failure. The Bearing 6006 should be inspected for radial clearance (CN class) every 6 months to ensure optimal performance.

• Fastener Check: Tighten KHT5500-235 Bolts (1/2″UNC), KHT7625-433 Hex bolts (7/16″UNF×1 1/4″), and GB/T70.1-2000 Screws (M8X20) every 100 working hours. Loose fasteners cause vibration, which damages gear trains and jaw assemblies. Use the correct torque wrench setting—over-tightening strips threads, while under-tightening leads to loosening.

• Avoid Generic Parts: Never use generic parts as a "quick fix." For example, a generic Bearing 6006 may last only 2,500 working hours, while our GB/T276-94 compliant bearing lasts 9,500 working hours. Always check the part number and model compatibility before installation to avoid equipment damage and downtime.
