Introduction: High-Quality Accessories for Oilfield Power Tongs & Casing Head Tongs
In the demanding world of oil and gas drilling, every small component can make or break your operations. From the precision GB/T283-1994 Bearing NJ315E to the heavy-duty 71 816-S BV-100C Casing Head Tong, our product range is specifically engineered to fit and enhance the performance of key oilfield equipment. We focus on the equipment you rely on daily: KHT5500 series power tongs, 71 816-S BV-100C casing head tongs, 70 884-S Lug Jaw Assemblies, XYQ6B and XYQ12 series tubing power tongs, and BV-55, BV-65, BV-100C lever-equipped tools. Our core purpose is to solve the biggest pain points for oilfield operators, drilling contractors, and maintenance teams: frequent part failures, mismatched components, and unplanned downtime that costs valuable time and money. Whether you’re running casing operations in the Permian Basin or conducting well workover in the North Sea, our accessories ensure your equipment runs smoothly, safely, and efficiently—no more waiting for incompatible parts or dealing with premature failures.
Product Overview: Comprehensive Oilfield Accessories You Can Trust
Our product lineup covers every critical accessory needed for tubing power pliers, casing head tongs, and related drilling equipment, all manufactured to meet or exceed strict industry standards like GB/T283-1994, GB/T5783-2000, GB/T95, GB/T10708.1, GB/T10708.3, and GB70.1-2000. We also comply with international standards such as SAE J429 for fasteners and API Spec Q1 for oilfield equipment, ensuring each part meets the highest quality and safety requirements. With 18 years of experience supplying oilfield accessories, we hold ISO 9001, ISO 14001, and ISO 45001 certifications, giving you the confidence that every component is built to last. Each part is tested under real-world oilfield conditions, from extreme temperatures (-45℃ to +120℃) to high pressure (up to 35 MPa for casing head tong components), so you can trust them to perform when you need them most.
Key Product Features & Pain Point Solutions
1. Structural Characteristics
Every component is designed for durability and longevity, addressing the common issue of premature wear and failure. The GB/T283-1994 Bearing NJ315E features a cylindrical roller design with high-grade alloy steel, reducing friction and extending service life to 9,200 operating hours—2,200 hours longer than standard bearings. Our 71 816-S BV-100C Casing Head Tong is built with a rugged steel frame and reinforced jaw assemblies, capable of handling hanging loads up to 1800 kN without deformation. The KHT5500-56 Rear Jaw Plate 5 (2 Knives 8″) is made with a heat-treated alloy that resists wear, lasting 7,800 hours compared to the 4,500-hour lifespan of generic jaw plates. Even small parts like the GB/T5783-2000 Bolt M16X50 are zinc-plated and heat-treated to HRC 30-34, preventing rust and seizing in corrosive oilfield environments.
2. Functional Advantages
Our accessories are engineered to make your work easier and more efficient, solving daily operational frustrations. The KHT7625-612 VG35-3-004 Five-way valve assembly (Parker) responds in 0.028 seconds, ensuring precise control of hydraulic systems and eliminating lag that causes operational delays. The KHT5500-15 Torque testing assembly of master tong provides accurate torque readings (±2 N·m), preventing over-tightening or under-tightening of pipe connections—which often leads to leaks or pipe damage. The GB/T10708.3 Seal FA48x40x5 features a composite rubber material that maintains a tight seal even under 35 MPa pressure, solving the common problem of hydraulic leaks in power tongs. Our KHT5500-183 Declutch shift (Upper) ensures smooth gear changes, reducing wear on transmission components and minimizing downtime.
3. Applicable Working Conditions
Our accessories are built to perform in the harshest oilfield environments, from onshore shale plays to offshore platforms. They withstand extreme temperatures (ranging from -45℃ in the Bakken Shale to +120℃ in the Middle East), high humidity, and corrosive exposure to drilling fluids and seawater. Whether you’re operating in the dusty Permian Basin, the salty Gulf of Mexico, or the cold North Sea, our components will hold up—reducing the need for frequent replacements and unplanned maintenance. They’re compatible with well workover, casing, and tubing operations, making them a versatile solution for all your drilling needs.

On-Site Fault Repair Cases (Real Oilfield Scenarios)
We’ve helped oilfield teams around the world resolve critical equipment issues with our high-quality accessories. Here are 4 real cases that demonstrate how our products deliver tangible results:
Case 1: Permian Basin, Texas – Bearing Failure in Casing Head Tong
Location: Permian Basin, Texas | Equipment: 71 816-S BV-100C Casing Head Tong | Load: 1600 kN hanging load | Fault: Original bearing seized, stopping casing operations and causing 7 hours of downtime. Our Solution: GB/T283-1994 Bearing NJ315E. Repair Result: Bearing operated smoothly for 9,200 hours without maintenance. Customer Feedback: “The replacement bearing is far more reliable than the OEM part—we haven’t had a single failure, and our downtime has dropped significantly.”
Case 2: North Sea Offshore Platform – Hydraulic Valve Malfunction
Location: North Sea Offshore Platform | Equipment: XYQ12 tubing power tong | Load: 22 MPa hydraulic pressure | Fault: Five-way valve lagged, causing imprecise jaw control and pipe slippage. Our Solution: KHT7625-612 VG35-3-004 Five-way valve assembly (Parker). Repair Result: Valve response time reduced to 0.028 seconds, precise control restored, no pipe slippage in 8 months. Customer Feedback: “The new valve fixed the lag completely—our operators can work faster and safer, with no more costly pipe damage.”
Case 3: Bakken Shale, North Dakota – Jaw Plate Wear
Location: Bakken Shale, North Dakota | Equipment: 70 884-S Lug Jaw Assembly | Load: 3800 N·m torque | Fault: Original jaw plates wore out after 4,500 hours, causing frequent replacements. Our Solution: KHT5500-56 Rear Jaw Plate 5 (2 Knives 8″). Repair Result: Jaw plates lasted 7,800 hours, reducing replacement frequency by half. Customer Feedback: “The wear resistance is impressive—we’re saving time and money on replacements, and our operations are more consistent.”
Case 4: Gulf of Mexico – Bolt Corrosion
Location: Gulf of Mexico Offshore Rig | Equipment: KHT5500 power tong | Load: 2500 N·m torque | Fault: Generic bolts rusted and seized, requiring 4 hours of downtime to replace. Our Solution: GB/T5783-2000 Bolt M16X50. Repair Result: Bolts remained corrosion-free for 12 months, no seizing or failures. Customer Feedback: “These bolts hold up in the salty air better than any we’ve used before—no more wasted time on rusted parts.”
Maintenance & Engineer Tips (Practical, On-Site Advice)
Our senior oilfield engineers have compiled these practical tips to help you maximize the life of your accessories and avoid common pitfalls:
• Inspect the GB/T283-1994 Bearing NJ315E every 600 operating hours—lubricate with ISO VG 68 high-temperature grease to prevent friction and wear (avoid using low-grade grease, which reduces service life by 30%).
• Clean the KHT7625-612 VG35-3-004 Five-way valve assembly every 2 months to remove debris buildup, which can cause lag or valve failure—use a non-corrosive cleaner to protect the valve’s internal components.
• Check the KHT5500-56 Rear Jaw Plate for wear every 1,000 hours—replace if the wear depth exceeds 1.2 mm (worn jaw plates can cause pipe slippage and damage).
• Store fasteners (like GB/T5783-2000 Bolt M16X50 and GB70.1-2000 Screw M8X25) in a dry, sealed container—even zinc-plated bolts can rust if exposed to moisture for extended periods.
• When replacing the KHT5500-183 Declutch shift (Upper), ensure proper alignment with the gearbox—misalignment causes premature wear and can lead to gear failure within 1,500 hours.
