Product Overview: Key Components & Practical Solutions

Product Introduction

Our spare parts portfolio is tailored to the most widely used oil drilling and workover equipment, focusing on components that are critical to operation and prone to wear. We supply everything from small but essential parts like the ZQ100 positioning pin (0101-08M) and TQ340-35 casing power tong gasket (22.300.03) to large assemblies such as the TQ35 idler assembly (13-3/8″ 56.550-00) and ZQ-100 hydraulic motor (1JMD-63). Every part is a direct replacement for original components, meaning no modifications are needed during installation—saving your maintenance team hours of work and reducing the risk of installation errors that can cause further equipment damage. We provide clear procurement reference standards, including part numbers, compatibility details, and technical specifications (such as the ZQ203-125 hydraulic oil filter ZSX-400*30 with 30μm filtration precision), to help you quickly find the exact part you need, even in emergency situations. Our parts also support the shift from external procurement dependence to more efficient in-house maintenance, helping teams reduce costs and improve response times.

Function & Structure Features

Each component is designed to solve real on-site problems, with functionality and durability at the forefront. For example, the ZQ100/ZQ203-100 relief valve (YF-B20H3S/YF-B20H3-S) automatically releases excess pressure when the hydraulic system exceeds 20MPa, preventing system bursts and equipment damage—a common issue that can cause 10+ hours of downtime. The TQ340-35 casing power tong torque gauge shield (24.430.00) protects the torque gauge from impact and debris, solving the problem of gauge damage that leads to inaccurate torque readings and pipe damage. Structurally, our parts are built to last: the ZQ203-125 hydraulic oil filter (ZSX-400*30) features a cartridge filter design with 30μm filtration precision, trapping small impurities to prevent hydraulic system clogging and extending the life of pumps and valves; it can withstand a maximum working temperature of 120°C and operating pressure up to 210 bar, making it ideal for harsh hydraulic systems. The TQ340-35 brake belt (56.521.00) uses high-temperature resistant rubber that withstands up to 160°C, avoiding premature wear in high-heat operations. Many parts adopt modular design for easy maintenance—for instance, the TQ35 jaw plate assembly (7″ 56.620.00) can be replaced in 16 minutes, compared to 38 minutes for generic alternatives. Additionally, our KaVo SE350T casing slip tooth plate (001605020) is designed to securely clamp casing without damage, solving the problem of pipe slippage during operations.

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 8,500 meters), sour oilfields, and harsh environments with high humidity, dust, and corrosive drilling mud. They are compatible with a wide range of equipment and handle heavy loads—such as the KaVo SDML 2-7/8″ 250t drill pipe slips, which safely handle loads up to 250 tons, and the TQ340-35 casing power tongs, which operate at 350 tons load capacity. The ZQ203-100/125 drill pipe power tongs, with our compatible spare parts, can handle pipe diameters from φ89mm to φ244mm, making them versatile for various drilling tasks. Whether you’re working in the Permian Basin (USA), the North Sea (Norway), the Middle East’s sour oilfields, or the onshore fields of Brazil, our parts deliver consistent, reliable performance. They meet offshore safety standards (consistent with API 17K requirements for marine equipment), including saltwater corrosion resistance, and are suitable for low-temperature environments (down to -40°C) with specialized materials. Our parts also perform reliably in high-pressure applications, where generic parts often have significantly shorter service lives.

Maintenance & Engineer Practical Tips

To extend the service life of our spare parts and keep your equipment running at peak performance, our senior drilling engineers (with 22+ years of on-site experience) share these practical tips—learned from hundreds of on-site repairs and maintenance checks: 1) Inspect the ZQ203-125 hydraulic oil filter (ZSX-400*30) every 650 operating hours and replace it if the pressure difference exceeds 0.35MPa; clogged filters can damage hydraulic motors and valves, as even small impurities can wear down components over time. 2) Tighten the ZQ100 brake band adjusting bolt (M48ZQ203) to 90 N·m using a torque wrench—over-tightening causes brake drag, while under-tightening reduces braking efficiency. 3) Apply high-temperature grease to the TQ340-35 casing power pliers shaft sleeve (56.650.01) every 260 operating hours to reduce friction, extending its service life by 1,100 hours. 4) Replace the TQ340-35 casing power tong gasket (22.300.03) every 700 operating hours, even if it’s not leaking—gaskets degrade over time and can fail unexpectedly, leading to oil leakage and equipment damage. 5) Avoid using generic TQ340-35 quick release valves (KPT-L10)—we’ve seen teams use cheap alternatives that stick after 280 operating hours; our valves maintain smooth operation for 1,400 operating hours. A common mistake is neglecting the ZQ203-100 spring pin (0102-27M)—check for bending every 450 operating hours, as a bent pin can cause jaw plate failure.
