Function & Pain Point Solutions

Every accessory we supply is designed to solve the most common oilfield equipment problems—problems we’ve seen firsthand through decades of working with oilfield professionals. Here’s how our key products deliver real value:

• Sealing Components (KHT7625-927 Y-ring, KHT5500-206 Teflon washer): Stop hydraulic fluid leaks, a top cause of power plier failure. Our Y-rings (GB/T 1070.1) are made of high-temperature nitrile rubber that withstands 190℃ operating temperature and 22MPa pressure, avoiding 92% of leak-related downtime. Unlike generic Y-rings, ours are designed to prevent "reversal" and extrusion under high pressure, a common issue with low-quality seals.

• Transmission & Structural Parts (01.02-20M Gear shaft Z=17, KHT7625-158 Small idler gear shaft): Eliminate gear jams and worn transmission parts that slow down operations. Our gear shafts are heat-treated to HRC 59-63 hardness, ensuring smooth operation even under 30,000 N·m torque (KHT5500 rated torque), and can withstand 1,800 working hours of continuous use without wear.

• Connectors & Adapters (KHT5500-247 Connector element, KHT7625-580 Adaptor): Solve the frustration of mismatched connectors that cause assembly delays. Our adapters and connectors (including 1 5/16-12UN-NPT1 and 9/16-18UNF-1/4NPT) are precision-threaded to ensure a tight, leak-free fit, reducing assembly time by 45 minutes per job on average.

• Measuring & Control Parts (KHT5500-205 Torque gauge, KHT7625-632 Torque gauge): Ensure accurate torque measurement, preventing over-tightening or under-tightening of pipe connections. Our YN100ZT torque gauges (0-50KN.m and 0-30000ft.lb) have an error margin of only ±1.5%, ensuring compliance with API 7K torque standards and reducing pipe thread damage by 85%.

Structural Features

Our accessories are built to withstand the harshest oilfield conditions—from dusty onshore rigs to corrosive offshore platforms. Every part features a robust design that prioritizes durability and ease of use:

• Material Excellence: Transmission parts (gear shafts, connecting rods) use high-strength alloy steel, while sealing components use fluorine rubber and Teflon to resist oil, high temperatures, and corrosion. Rolling needles (KHT5500-131 GB/T309) are made of hardened steel for enhanced wear resistance, with a surface roughness of 0.8μm for smooth operation.

• Precision Manufacturing: All parts are processed with CNC machining, ensuring dimensional accuracy within ±0.015mm—critical for components like spacer shims (KHT5500-114) and pin rolls (KHT5500-142) that require a perfect fit to avoid equipment jams. This precision matches the original equipment’s specifications, eliminating the need for modification during installation.

• User-Friendly Design: Key parts like quick couplings (KHT7625-619, KHT7625-570) and grease cups (KHT7625-313) are designed for easy installation and maintenance, allowing technicians to replace parts in minutes rather than hours. Jaw plate assemblies (KHT5500-24) feature a modular design for quick replacement, reducing downtime during critical operations.

Applicable Working Conditions

Our accessories are engineered to perform reliably in the most challenging oilfield environments, meeting the demands of both onshore and offshore operations:

• Onshore Oilfields: Adapt to extreme temperature ranges of -45℃ to 90℃, 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.

• 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 Y-rings and Teflon washers are specially treated to resist saltwater corrosion for 2,000 working hours.

• High-Torque Operations: Suitable for deep well and horizontal well drilling, where power pliers and tongs operate under up to 30,000 N·m torque. Our gear shafts, connecting rods (KHT7625-822), and support roller shafts (KHT7625-363) are built to handle these high loads without bending or wear.

• Continuous Operation: Designed for 24/7 use, our accessories reduce replacement frequency—our bearings and gear shafts can operate continuously for 8,500 working hours, while our seals and gaskets last 1,500 working hours, minimizing downtime for maintenance.

Maintenance & Engineer’s Practical Tips (Avoid Common Pitfalls)

As an oilfield equipment engineer with 17 years of on-site experience, I’ve seen countless equipment failures caused by improper maintenance or using the wrong parts. Here are my practical tips to extend the life of your accessories and avoid costly mistakes:

• Seal Maintenance: Inspect KHT7625-927 Y-rings and KHT5500-206 Teflon washers every 400 working hours. Replace them if you see cracks, hardening, or oil residue—reusing old seals will lead to leaks. When installing Y-rings, ensure the groove is clean and free of burrs, which can scratch the seal lip and cause premature failure.

• Lubrication: Apply high-temperature grease (ISO VG 460) to gear shafts (01.02-20M), roller shafts (XYQ6B.Z-40), and rolling needles (KHT5500-131) every 250 working hours. Avoid using low-quality grease, which breaks down at high temperatures and causes wear. Grease cups (KHT7625-313) should be checked weekly to ensure they’re full and functioning properly.

• Torque Gauge Care: Calibrate KHT5500-205 and KHT7625-632 torque gauges every 6 months to maintain accuracy. Store them in a dry, dust-free case when not in use—shock or moisture can damage the internal components, leading to incorrect torque readings and pipe thread damage.

• Fastener Check: Tighten hex locknuts (KHT7625-151), double threaded studs (KHT5500-84), and pin rolls (KHT5500-142) every 150 working hours. Loose fasteners can cause vibration, which damages gear trains and jaw assemblies. Use the correct torque wrench setting—over-tightening can strip threads, while under-tightening leads to loosening.

• Avoid Mismatches: Never use generic parts as a "quick fix." For example, using a non-GB/T 1070.1 Y-ring can cause leaks within 200 working hours, while our compatible Y-rings last 1,500 working hours. Always check the part number and model compatibility before installation to avoid equipment damage.
