KHT5500/KHT7625/XQ89/3YC Tubing & Pipe Oil Power Pliers Accessories Supply

Introduction: Solve Your Oilfield Accessory Troubles with Precision-Matched Parts

In oilfield drilling and well workover operations, the reliability of tubing power pliers and pipe oil power pliers directly determines operational efficiency and safety. A single worn gasket, damaged gear shaft, or mismatched bearing can lead to equipment downtime, delayed projects, and increased maintenance costs—problems that every oilfield maintenance supervisor, equipment technician, and procurement manager dreads. We specialize in supplying fully compatible accessories for core equipment models, including KHT5500, KHT7625, XQ89/3YC, XQ8/3YC, XYQ6B, and XYQ12 series, as well as manual tongs like 800 500-S-160 WRT-160. Our products cover every critical component you need, from inner hexagons (M10*20) and nuts (M24) to complex assemblies like main tong jaw plate frame (XYQ12.Z.1.1) and double gear assemblies (XYQ6B.Z-5), all designed to eliminate the "mismatch headache" and keep your equipment running at peak performance.

Our core purpose is simple: to provide oilfield professionals with high-quality, standard-compliant accessories that fit perfectly, last longer, and reduce operational disruptions. Every part we supply adheres to strict industry standards such as GB/T6178, GB/T3452.1, GB/T5781-2000, and GB276, ensuring compatibility with your existing equipment and compliance with oilfield safety regulations. With 18 years of experience in oilfield accessory production and supply, we’ve served over 320 oilfields worldwide, delivering 120,000+ reliable parts that have proven to extend equipment service life by 1,200 working hours on average compared to generic alternatives.

Function & Pain Point Solutions

Every accessory we supply is engineered to solve real oilfield pain points. Here’s how our key products deliver value:

• Sealing Components (O-Ring 56×3.55 KHT7625-922, XYQ12.Z-23 Gasket): Prevent hydraulic fluid leaks, which are a top cause of power plier failure—our O-rings are made of high-temperature resistant material that withstands 180℃ operating temperature and 20MPa pressure, avoiding 90% of leak-related downtime.

• Mechanical Transmission Parts (Gear shaft KHT5500-118, Pinion gear KHT7625-217): Reduce wear and tear on power transmission systems, solving the problem of frequent gear jams—our gear shafts are heat-treated to achieve a hardness of HRC 58-62, ensuring smooth operation even under 27,000 N·m torque (KHT5500 low gear torque).

• Bearing & Fasteners (Deep groove ball bearing 6202 KHT7625-353, Bolt M16X40 GB/T5781-2000): Eliminate loose or worn parts that cause equipment vibration—our bearings have a service life of 8,000 working hours, and fasteners meet GB/T standards to ensure secure installation even in high-vibration drilling environments.

• Jaw & Structural Parts (Main pliers jaw frame XYQ6B.Z-35, Front Jaw Plate KHT5500-47): Solve the problem of slipping or damaged jaws that reduce clamping force—our jaw plates are made of wear-resistant alloy, maintaining clamping stability even after 3,000+ make-up/break-out cycles.

Structural Features

Our accessories stand out for their robust structural design, built to withstand the harsh conditions of oilfield operations:

• Material Selection: High-strength carbon steel and alloy steel are used for transmission parts, while sealing components use nitrile rubber and fluorine rubber to resist oil, high temperature, and corrosion—perfect for offshore and onshore oilfield environments.

• Precision Manufacturing: All parts are processed with CNC machining, ensuring dimensional accuracy within ±0.02mm, which guarantees a perfect fit with original equipment without modification.

• Modular Design: Key assemblies like main tong jaw plate frame (XYQ12.Z.1.1) and double gear assembly (XYQ6B.Z-5) are designed as modular units, making replacement quick and easy, reducing maintenance time by 40%.

Applicable Working Conditions

Our accessories are engineered to perform reliably in the most challenging oilfield environments, including:

• Onshore Oilfields: Adapt to temperature ranges of -40℃ to 85℃, resisting dust, sand, and heavy vibration during drilling and workover operations.

• Offshore Oilfields: Corrosion-resistant materials prevent damage from saltwater and humid air, ensuring stable performance in marine environments.

• High-Torque Operations: Suitable for high-pressure drilling scenarios where power pliers need to deliver up to 27,000 N·m torque (KHT5500 low gear), such as deep well and horizontal well drilling.

• Continuous Operation: Designed for 24/7 continuous use, our accessories reduce the frequency of replacements, ensuring uninterrupted production.

Maintenance & Maintenance Tips (Engineer’s Practical Advice)

As an experienced oilfield equipment engineer with 15 years of on-site maintenance experience, I’ve seen countless equipment failures caused by improper maintenance. Here are my practical tips to extend the life of your accessories:

• Regular Inspection: Check O-rings (KHT7625-922) and gaskets (KHT5500-121) every 500 working hours—replace them if there are signs of cracks or hardening to avoid leaks. Do not reuse old gaskets, as they lose elasticity and sealing performance.

• Lubrication: Apply high-temperature grease to bearings (6202, 208) and gear shafts (KHT5500-118) every 300 working hours. Use grease that meets ISO VG 460 standards to ensure smooth operation and prevent wear.

• Fastener Check: Tighten hexagon bolts (KHT5500-179, KHT5500-273) and screws (GB/T68-1985) every 200 working hours, especially in high-vibration areas—loose fasteners can cause severe damage to gear trains and jaw assemblies.

• Storage: Store spare parts in a dry, dust-free environment. Avoid placing heavy objects on fragile parts like springs (KHT7625-64) and cotter pins (KHT7625-483) to prevent deformation.

• Avoid Overload: Do not use power pliers beyond their rated torque (e.g., KHT5500’s maximum low gear torque of 27,000 N·m)—this can damage gear shafts and piston rods (KHT7625-918) and shorten their service life.
