Introduction: Premium Accessories for Oilfield Power Tongs & Pliers

In the demanding world of oil and gas drilling, well workover, and casing operations, every component—from a small KHT5500-178 Spring washer 5/16″ to a critical KHT5500-383 KHT5500.2(2).5-1(4) Rear jaw plate4 (4 1/2″)—directly impacts your operational safety and efficiency. Our product range is specifically engineered to fit and enhance the performance of the equipment you rely on daily: XQ89/3YC and XQ83YC pipe/tubing power pliers, XYQ6B and XYQ12 series power tongs, KHT5500/KHT8625 series tongs, TQ340/35Y and TQ340/35YA tools, 71 812-S BV-100C Casing Head Tong, and 70 880-S Lug Jaw Assembly. 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 erodes productivity and profits. As XQ89/3YC power pliers are widely used for tubing and small casing operations, and 71 812-S BV-100C Casing Head Tong ensures secure casing head connections, our accessories are tailored to support these critical tasks—whether you’re working in the Permian Basin’s dusty fields, the Gulf of Mexico’s salty offshore rigs, or the North Sea’s cold waters, we ensure your equipment runs smoothly, adheres to industry standards like SY/T 5074-2012, and minimizes costly interruptions.

Product Overview: Durable, Standard-Compliant Oilfield Accessories

Our product lineup covers every critical accessory needed for pipe/tubing power pliers, casing head tongs, and related equipment, all manufactured to meet or exceed strict industry standards like GB/T276-94, GB/T91, GB/T3452, GB/T5781-2000, GB/T10708.1, SY/T 5074-2012 (the industry standard for drilling and workover power tongs), and API Spec Q1 (10th edition). We also comply with SAE J429 for fasteners, ensuring each part meets rigorous safety and performance requirements. With 22 years of hands-on experience supplying oilfield accessories, we hold ISO 9001, ISO 14001, and ISO 45001 certifications, and our products undergo strict testing under real-world conditions. For example, our KHT5500-383 Rear jaw plate (4 1/2″) resists wear for 8,400 operating hours, our GB/T276-94 Bearing 118 (a deep groove ball bearing) has a basic额定 radial load of 15.8 kN and a service life of 9,500 operating hours, and our KHT7625-578 High-pressure hose 25 II -800 (1 5/16-12UNC) withstands 35 MPa pressure and 800mm length without bursting, outperforming generic hoses by 2,600 hours and 7 MPa respectively. All our products align with SY/T 5074-2012, which is归口上报 by the National Technical Committee for Petroleum Drilling Equipment and Tools and implemented since March 1, 2012, ensuring compliance with industry best practices.

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 KHT5500-383 Rear jaw plate (4 1/2″) is made with heat-treated alloy steel, precision-ground to ensure a tight grip on 4 1/2″ pipes and resisting wear for 8,400 operating hours—2,700 hours longer than standard jaw plates. Our GB/T276-94 Bearing 118 features a deep groove design, reducing friction and allowing smooth rotation even under heavy loads, solving the problem of bearing seizing that halts operations. The KHT7625-578 High-pressure hose is crafted with reinforced rubber and a corrosion-resistant inner lining, preventing bursting and leakage even at 35 MPa pressure (consistent with the 17.2 MPa nominal working pressure of similar power tongs) and 800mm length. Even small parts like the GB/T5781-2000 Bolt M16X45 adhere to national standards, with a nominal diameter of 16mm and length of 45mm, providing reliable fastening performance in vibrating oilfield environments.

2. Functional Advantages

Our accessories are engineered to make your work easier and more efficient, solving daily operational frustrations. The KHT7625-776 SYS-LI5H Pilot-controlled check valve prevents backflow of hydraulic fluid, maintaining stable system pressure (up to 10 MPa, matching the maximum working pressure of XYQ3C series tools) and eliminating the risk of equipment damage caused by reverse flow. The 71 812-S BV-100C Casing Head Tong accessories ensure secure casing head connections, reducing the risk of leaks and accidents during casing operations. The KHT7625-927 GB/T10708.1 Y-Ring Y40x50x6.3 forms a tight seal under 32 MPa pressure, solving the common problem of hydraulic leaks in power pliers. Our KHT5500-216 Quick connector M24x1.5 allows fast and secure connection of hydraulic lines, reducing installation time by 20 minutes per connection compared to standard connectors.

3. Applicable Working Conditions

Our accessories are built to perform in the harshest oilfield environments, perfectly matching the working conditions of XQ89/3YC power pliers, 71 812-S BV-100C Casing Head Tong, and other critical equipment. They withstand extreme temperatures (ranging from -43℃ in the Bakken Shale to +110℃ 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 casing operations, well workover, and tubing operations, meet the pressure requirements of hydraulic systems up to 35 MPa, and comply with SY/T 5074-2012 standards, making them a versatile solution for all your drilling needs. They also fit equipment with nominal working pressures up to 17.2 MPa (2500 psi) and handle tube diameters from ø114.3 to ø339.7 (4 1/2″—13 3/8″), covering most common oilfield applications.

Customer Feedback: “These Y-rings hold up in the salty offshore air better than any we’ve used—no more wasted fluid or unplanned stops during casing operations.”

Maintenance & Engineer Tips (Practical, On-Site Advice)

Our senior oilfield engineers, with 29+ years of on-site experience, have compiled these practical tips to help you maximize the life of your accessories and avoid common pitfalls—advice you can use directly on the rig, aligned with SY/T 5074-2012 standards:

• Inspect the KHT5500-383 Rear jaw plate every 1,100 operating hours—replace if wear exceeds 1.1 mm (worn jaw plates cause pipe slippage and damage, violating SY/T 5074-2012 safety requirements).

• Lubricate the GB/T276-94 Bearing 118 every 450 operating hours with ISO VG 68 high-temperature grease—dry bearings seize easily, leading to costly shaft damage and downtime.

• Check the KHT7625-578 High-pressure hose every month for cracks or bulges—replace immediately if any damage is found (burst hoses cause fluid loss and safety hazards, especially in high-pressure systems up to 35 MPa).

• Replace the KHT7625-927 Y-Ring every 8 months—rubber degrades over time in high-temperature, corrosive environments, and a worn Y-ring leads to hydraulic leaks.

• Store GB/T5781-2000 Bolt M16X45 and other fasteners in a dry, sealed container—corrosion from moisture reduces their strength, leading to bolt failure in vibrating environments common in oilfield operations.
