Function & Value: What These Parts Solve for You

Each part in our range is designed to address specific pain points oilfield teams face daily:

• Jaw Sets & Plates (KHT7625-801, KHT5500-309, XYQ12 Back Tong Jaw Assembly): Prevent slippage during pipe makeup/breakout with hardened steel construction that resists wear—solving the problem of frequent jaw replacements and ensuring consistent torque application (up to 125,000 N·m for compatible tongs).

• Seals & Gaskets (KHT5500-461 O-Ring, XQ89/3YC O-Type Sealing Ring): Stop hydraulic leaks that waste fluid and reduce pressure, with high-temperature resistance (up to 180°C) and chemical compatibility with drilling fluids—eliminating unplanned stops for leak repairs.

• Fasteners (KHT5500-82 Hexagon Socket Cap Head Screws, GB/T5781-2000 Bolt): Withstand high vibration and torque without loosening, complying with GB/T standards to prevent component detachment and equipment failure.

• Bearings & Rollers (KHT5500-49 Roller, KHT5500-138 Bearing Strip): Reduce friction and wear in moving parts, extending the life of your power tongs and reducing maintenance frequency.

Structural Features: Built for Oilfield Toughness

Our spare parts are engineered to survive the harshest oilfield conditions, with structural features that prioritize durability and performance:

All metal components (jaws, bolts, bushings, piston rods) are made from high-strength alloy steel,经过 heat treatment to achieve a hardness of HRC 45-50—ensuring resistance to impact, wear, and corrosion. Seals are crafted from nitrile rubber or fluorocarbon, providing excellent resistance to drilling mud, oil, and extreme temperatures. Precision machining ensures tight tolerances (±0.02mm) for all parts, guaranteeing a seamless fit with your existing equipment. Additionally, components like the KHT5500-455 Piston Rod feature a chrome-plated surface to reduce friction and prevent rust, while the KHT5500-138 Bearing Strip uses self-lubricating material to minimize maintenance needs.

Applicable Working Conditions

These spare parts are designed to perform reliably in the most challenging oilfield environments, including:

• Land and offshore drilling rigs (compatible with ZQ series power tongs rated up to 125,000 N·m torque)

• High-temperature areas (operating range: -40°C to 180°C)

• High-pressure hydraulic systems (up to 3600 PSI, compatible with KHT5500-205 Pressure Gauge)

• Corrosive environments with drilling mud, saltwater, and chemicals

• Heavy-load operations (handling pipe sizes from 1″ to 8″, as supported by KHT7625-813 Rear Jaw Set)

We supply the following spare parts:

On-Site Maintenance & Engineer Tips

To maximize the lifespan of your spare parts and equipment, our senior oilfield engineers recommend the following practical tips—based on 20+ years of on-site experience:

• Daily Inspection: Check jaw sets and dies for wear (replace when the wear depth exceeds 1.5mm) and ensure O-rings are free of cracks or deformation. Use the KHT7625-150 NPT 1/8 Grease Cup to lubricate pivot points daily—this reduces friction and extends bearing life by 50%.

• Torque Specifications: When installing fasteners like KHT5500-82 Hexagon Socket Cap Head Screws, use a torque wrench set to 35 ft-lbs (for 1/4″x3/4″ size) to avoid over-tightening, which can strip threads or damage components.

• Seal Replacement: Replace O-rings (like KHT5500-461) every 6 months or immediately if leaks are detected—using non-compatible seals can lead to hydraulic system failure and costly repairs.

• Storage: Store spare parts in a dry, temperature-controlled area to prevent rust. Avoid stacking heavy parts on jaw plates or delicate components like pressure gauges.

• Risk Avoidance Tips: Never use generic washers or bolts as a replacement for GB/T or API-compliant parts (e.g., KHT5500-168 GB/T95 Flat Washer). Generic parts may not withstand high torque and can cause equipment failure.

Real On-Site Fault Repair Cases

These four real-world cases demonstrate how our spare parts solve critical downtime issues and deliver reliable results for oilfield operations:
