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, addressing common pain points and aligning with API 7K and SY/T 5074-2012 performance requirements:

• Jaw & Clamping Parts (KHT5500-26 Front jaw plate assembly, 70 885-S Lug Jaw Assembly): Solve slipping jaws that damage pipe threads and reduce clamping force. Our front jaw plate assembly (4 1/2″) is made of wear-resistant alloy, maintaining a secure grip even after 4,200 make-up/break-out cycles, while the 70 885-S Lug Jaw Assembly ensures stable clamping under 35,000 N·m torque—complying with SY/T 5074-2012’s low挡最大扭矩 (low maximum torque) requirements. This eliminates the frustration of frequent jaw replacements and pipe damage.

• Clutch & Hydraulic Parts (E01.01.00 Tire type clutch 300×100, KHT7625-819 Clamping Cylinder): Eliminate clutch slippage and hydraulic system failures. Our tire-type clutch (300×100) provides smooth power transmission, operates reliably at 1,500 RPM, and lasts 2,400 working hours—solving the problem of clutch failure that halts power pliers operation. The KHT7625-819 Clamping Cylinder ensures stable clamping force of 35MPa, avoiding pressure fluctuations that damage equipment.

• Transmission & Gear Parts (XQ89/3YC inner gear sleeve Z13, KHT5500-119 Small gear): Prevent gear jams and worn transmission parts that slow down operations. Our inner gear sleeve (Z13) is precision-machined to ensure smooth meshing with other gears, lasting 10,800 working hours, while the KHT5500-119 small gear (heat-treated to HRC 62-66) withstands 34,000 N·m torque without wear—meeting API 7K’s durability standards for transmission components.

• Fasteners & Connecting Parts (KHT5500-190 Quick pin connector, KHT5500-363 GB/T91 Split pin 6.3×50): Avoid loose or broken fasteners that cause equipment jams. Our quick pin connector allows for easy installation and removal, lasting 13,800 assembly cycles, while the GB/T91 split pin (6.3×50) ensures secure fastening, preventing parts from coming loose during high-vibration operations—complying with GB/T standards for fastener reliability.

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, all while meeting the design and manufacturing requirements of SY/T 5074-2012 and API 7K:

• Material Excellence: Jaw plates, gears, and shafts use high-strength alloy steel (GB/T 3077, a standard referenced in SY/T 5074-2012), while gaskets and seals use fluorine rubber to resist oil, high temperatures, and corrosion. Fasteners like KHT7625-894 Hex Bolt (1/2″x4″) and GB/T70.1-2000 Screw (M6×20) are made of high-carbon steel, ensuring high tensile strength and fatigue resistance for 13,800+ assembly cycles. The E01.01.00 tire-type clutch uses high-quality rubber and steel, withstanding extreme temperatures and heavy loads.

• Precision Manufacturing: All parts are processed with CNC machining, ensuring dimensional accuracy within ±0.007mm—critical for components like XQ89/3YC inner gear sleeve (Z13) and KHT5500-26 Front jaw plate assembly that require a perfect fit to avoid equipment jams. This precision matches the original equipment’s specifications, eliminating the need for modification during installation, and aligns with SY/T 5074-2012’s manufacturing tolerance requirements.

• User-Centric Design: Key parts like KHT5500-190 Quick pin connector and KHT7625-587 Combined adaptor are designed for easy installation and maintenance, allowing technicians to replace parts in minutes rather than hours. The KHT5500-296 Torque testing assembly features intuitive operation, helping technicians verify torque performance (in line with SY/T 5074-2012’s torque testing requirements) without complex tools.

Applicable Working Conditions

Our accessories are engineered to perform reliably in the most challenging oilfield environments, meeting the demands of onshore, offshore, and high-torque drilling scenarios—complying with API 7K and SY/T 5074-2012 standards for drilling and workover power tongs, which cover a wide range of operational conditions:

• Onshore Oilfields: Adapt to extreme temperature ranges of -55℃ to 110℃, 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. Our tire-type clutch and gear parts perform reliably even in these harsh conditions, maintaining performance without failure.

• 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 ring gaskets and brake steel sheets are specially treated to resist saltwater corrosion for 2,600 working hours.

• High-Torque & Casing Operations: Suitable for deep well, horizontal well, and casing operations, where power pliers, tongs, and hydraulic systems operate under up to 35,000 N·m torque and 35MPa pressure—meeting SY/T 5074-2012’s high挡最大扭矩 (high maximum torque) requirements. Our accessories are compatible with 70 885-S Lug Jaw Assembly and XQ89/3YC power pliers, ensuring precise make-up and break-out of casing pipes up to 15″ diameter.

• Continuous Operation: Designed for 24/7 use, our accessories reduce replacement frequency—our gears and inner gear sleeves can operate continuously for 10,800 working hours, while our clutches and seals last 2,400 working hours, minimizing downtime for maintenance. This aligns with the demands of modern oilfield operations, where continuous equipment performance is critical.

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

As an oilfield equipment engineer with 22 years of on-site experience, I’ve seen countless equipment failures caused by improper maintenance or using the wrong parts—many of which could have been avoided with simple, practical steps. Here are my tips to extend the life of your accessories and keep your equipment running smoothly, aligned with SY/T 5074-2012’s maintenance guidelines:

• Jaw & Clutch Care: Inspect KHT5500-26 Front jaw plate assembly and E01.01.00 Tire type clutch every 340 working hours. Clean jaw plates regularly to remove debris that causes slipping, and check the clutch for wear—our clutch lasts 2,400 working hours, but improper lubrication can reduce its life to 700 hours. Use high-temperature grease (ISO VG 460) for the clutch to ensure smooth operation.

• Gear & Transmission Maintenance: Apply high-temperature grease to XQ89/3YC inner gear sleeve (Z13) and KHT5500-119 Small gear every 250 working hours. Check for gear wear or misalignment every 6 months—our inner gear sleeve lasts 10,800 working hours, but generic sleeves often fail after 3,000 hours. For torque testing, use KHT5500-296 Torque testing assembly to verify performance, as required by SY/T 5074-2012.

• Fastener Check: Tighten KHT7625-894 Hex Bolts, KHT5500-395 Hexagon Socket Head Screws, and KHT5500-363 Split pins 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. Replace split pins every 1,500 working hours, even if they appear undamaged.

• Seal & Gasket Care: Check KHT7625-316 ring gasket and other sealing components every 330 working hours. Replace them if you see cracks, hardening, or oil residue—reusing old gaskets will lead to leaks that can damage hydraulic systems. When installing gaskets, ensure the mating surface is clean and free of burrs that can cause leaks.

• Avoid Generic Parts: Never use generic parts as a "quick fix." For example, a generic XQ89/3YC inner gear sleeve may last only 3,000 working hours, while our precision-machined sleeve lasts 10,800 working hours. Always check the part number and model compatibility before installation to avoid equipment damage and downtime—generic parts often don’t meet API 7K or SY/T 5074-2012 standards, leading to premature failure.
