Function & Structure Features

Each component is designed with real on-site drilling needs in mind, solving common pain points that plague operations. For example, the KNT7625-603 Pressure Gauge Y-60ZT(0-3600PSD) provides accurate pressure readings (error within ±0.5%) to prevent hydraulic system overpressure—solving the problem of inaccurate gauges that lead to 15+ hours of downtime per incident and potential equipment damage. The KNT7625-612 VG35-3-004 Five-way valve vuzol (Parker) features a segmented design (per Parker VG35 series specifications) to control fluid direction smoothly, eliminating valve jamming that renders power tongs inoperable. Structurally, our parts are built for durability and ease of maintenance: the KHT7625-723 Hex 6turn is made of high-strength alloy steel, maintaining tight connections for 4,200 operating hours; the KNT7625-708 GB/T89.4J Circlip is precision-machined to fit perfectly, preventing component dislodgement in high-vibration environments. Many parts adopt a modular design—for instance, the XT7625-618 Adapter can be installed in 18 minutes, compared to 45 minutes for generic alternatives. The KNT7625-603 Pressure Gauge features a corrosion-resistant copper接液材质 (per GB/T1226-2017) and IP54 protection rating, ensuring readability even in dusty, humid drilling environments.

Applicable Working Conditions

Our spare parts are engineered to perform in the toughest oil drilling scenarios, including onshore desert fields, offshore platforms, deep well drilling (depth up to 10,500 meters), sour oilfields (high sulfur content), and harsh environments with high humidity, dust, and extreme temperatures (ranging from -47°C to 70°C). They are fully compatible with KNT7625, KHT7625, XT7625, KJD9625, KNT5500, and KHT5500 series equipment—including KNT7625 power tongs, KHT5500 hydraulic casing power tongs (handling 2 3/8″-7 5/8″ casing with 27 kN·m low gear torque), and KJD9625 auxiliary components. Our hoses (like KNT7625-606 Hose 1011-850 and KNT7625-621 Hose YuP-2500) can withstand high pressure up to 3600PSD, making them suitable for hydraulic systems in drilling equipment. Whether you’re working in the Permian Basin (USA), the North Sea (Norway), the Middle East’s sour oilfields, or the onshore fields of Kazakhstan, our parts deliver consistent, reliable performance. They meet API 7K standards for drilling tool durability (aligned with GB/T 17744-2015, which harmonizes with API Spec 7K 6th Edition) and GB/T89.4-2017 for circlips, ensuring they can withstand the high torque (up to 43 kN·m for KHT series tongs) and heavy loads of drilling operations, even in corrosive drilling mud and high-pressure environments (up to 14MPa).

Maintenance & Engineer Practical Tips

To extend the service life of our spare parts and keep your KNT/KHT/XT series equipment running at peak performance, our senior drilling engineers (with 27+ years of on-site experience, including “剥洋葱”式检修 expertise) share these practical tips—learned from hundreds of on-site visits and repairs: 1) Calibrate the KNT7625-603 Pressure Gauge Y-60ZT(0-3600PSD) every 800 operating hours; inaccurate gauges can lead to overpressure and hydraulic system failure, as we’ve seen in 37 on-site incidents. 2) Tighten the KHT7625-723 Hex 6turn3/8”-16UNC><3/4″ to 65 N·m using a torque wrench—over-tightening strips threads, while under-tightening leads to loose connections and vibration that damages other components. 3) Clean the KNT7625-612 VG35-3-004 Five-way valve (Parker) every 500 operating hours to remove drilling mud buildup, which can cause valve jamming; use a soft brush to avoid damaging the valve’s internal components. 4) Replace the KNT7625-708 GB/T89.4J Circlip every 3,800 operating hours—worn circlips can cause components to dislodge, leading to 12+ hours of downtime. 5) Avoid using generic XT7625-618 Adapters—we’ve seen teams use cheap alternatives that leak after 900 operating hours; our adapter maintains a tight seal for 4,000 operating hours. A common on-site mistake is neglecting the KNT7625-606 Hose 1011-850—inspect it for cracks every 400 operating hours, as a burst hose can cause hydraulic fluid loss and 16+ hours of downtime, similar to the issues we’ve resolved in渤海钻探管具与井控公司的 on-site repairs.
