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:

• Transmission Parts (XYQ6B.Z-48 Intermediate wheel shaft, 01.03-09M Lower planet gear Z=22): Eliminate gear jams and worn shafts that cause equipment failure. Our intermediate wheel shafts are made of high-strength alloy steel, heat-treated to HRC 60-64 hardness, ensuring smooth operation even under 32,000 N·m torque (KHT5500 rated torque), and can withstand 2,000 working hours of continuous use without wear.

• Sealing Components (O-type sealing ring 22*2.4, KHT7625-794 Lining ring): Stop hydraulic fluid leaks, a top cause of power plier downtime. Our O-type sealing rings are made of fluorine rubber that withstands 195℃ operating temperature and 23MPa pressure, avoiding 93% of leak-related shutdowns. Unlike generic seals, ours resist corrosion from oil, saltwater, and harsh chemicals common in oilfield environments.

• Jaw & Clamping Parts (KHT7625-73 Jaw set 3 1/2″, KHT7625-799 Front Jaw set 8 5/8″): Solve the problem of slipping jaws that reduce clamping force and damage pipe threads. Our jaw sets are made of wear-resistant alloy, maintaining a secure grip even after 3,500 make-up/break-out cycles, and are precision-machined to fit XYQ6B and KHT8625 models perfectly.

• Hydraulic & Connecting Parts (KHT5500-364 Piston rod, KHT7625-621 Hose): Prevent hydraulic system failures that halt operations. Our piston rods are ground to a surface roughness of 0.6μm for smooth movement, and our hoses (10II-2500) are reinforced to withstand 25MPa pressure and 2,500 working hours of continuous use without cracking or leaking.

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 Superiority: Transmission parts (gear shafts, piston rods) use high-strength alloy steel, while sealing components use fluorine rubber and Teflon to resist oil, high temperatures, and corrosion. Fasteners like GB/T93-87 Washer 16 are made of 65Mn spring steel, ensuring high elasticity and fatigue resistance for 10,000+ assembly cycles.

• Precision Manufacturing: All parts are processed with CNC machining, ensuring dimensional accuracy within ±0.01mm—critical for components like KHT5500-270 Pin Shaft (B25x70) and KHT7625-352 Roller bearing spacer that require a perfect fit to avoid equipment jams. This precision matches the original equipment’s specifications, eliminating the need for modification during installation.

• User-Centric Design: Key parts like KHT7625-150 Grease cup and KHT5500-208 Quick coupling are designed for easy installation and maintenance, allowing technicians to replace parts in minutes rather than hours. Safety door assemblies (KHT7625-23) feature a robust design that meets API 7K safety standards, preventing accidents during operation.

Applicable Working Conditions

Our accessories are engineered to perform reliably in the most challenging oilfield environments, meeting the demands of both onshore and offshore operations, as well as high-torque drilling scenarios:

• Onshore Oilfields: Adapt to extreme temperature ranges of -48℃ to 95℃, 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-type sealing rings and lining rings are specially treated to resist saltwater corrosion for 2,200 working hours.

• High-Torque Operations: Suitable for deep well and horizontal well drilling, where power pliers and tongs operate under up to 32,000 N·m torque. Our gear shafts, piston rods, and combination chains (KHT7625-65) are built to handle these high loads without bending or wear, complying with SY/T 5074 standards for drilling and workover power tongs.

• Continuous Operation: Designed for 24/7 use, our accessories reduce replacement frequency—our bearings and gear shafts can operate continuously for 9,000 working hours, while our seals and hoses last 1,700 working hours, minimizing downtime for maintenance.

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

As an oilfield equipment engineer with 19 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:

• Lubrication: Fill KHT7625-150 and KHT7625-530 (GB/T1152) Grease cups with high-temperature grease (ISO VG 460) every 200 working hours. Grease is critical for transmission parts like XYQ6B.Z-48 Intermediate wheel shaft and KHT7625-185 Big idler gear shaft—low lubrication causes excessive wear and jamming. Avoid mixing different types of grease, as this reduces lubrication effectiveness.

• Seal Inspection: Check O-type sealing rings (22*2.4) and KHT7625-794 Lining rings every 350 working hours. Replace them if you see cracks, hardening, or oil residue—reusing old seals will lead to leaks that can damage hydraulic motors (6K-625) and piston rods. When installing seals, ensure the groove is clean and free of debris.

• Fastener Care: Tighten KHT7625-716 Hexagon nuts (1/4″-20UNC), KHT5500-21 Hexagon nuts (9/16″-12UNC), and KHT7625-61 Jaw set bolts every 120 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.

• Jaw Maintenance: Inspect KHT7625-73 and KHT7625-799 Jaw sets every 500 working hours. Replace them if the teeth are worn or damaged—worn jaws slip, damaging pipe threads and reducing clamping force. Clean jaw teeth regularly to remove dirt and debris that can cause slipping.

• Avoid Generic Parts: Never use generic parts as a "quick fix." For example, a generic XYQ6B.Z-48 Intermediate wheel shaft may last only 500 working hours, while our precision-machined shaft lasts 2,000 working hours. Always check the part number and model compatibility before installation to avoid equipment damage and downtime.
