Introduction: The Importance of Regular Maintenance for Bucking Units and Breakout Units
Bucking units and breakout units are indispensable tools in the oil and gas industry, used to efficiently connect and disconnect pipes under high pressure. These robust machines are designed to withstand tough operational conditions but still require regular maintenance to function optimally. Proper maintenance ensures that bucking units and breakout units continue to operate safely, reliably, and efficiently, minimizing downtime and reducing costly repairs.
In this article, we’ll highlight the best maintenance practices for bucking units and breakout units, focusing on lubrication, seal checks, pressure calibration, contamination prevention, and much more. Adopting these practices can enhance the longevity of your equipment and maximize its performance in the field.
Preventing Contamination in Hydraulic Systems of Bucking Units and Breakout Units
Contaminants such as dirt, water, and debris are one of the leading causes of premature wear and malfunction in bucking units and breakout units. Keeping your hydraulic system free of contaminants is crucial for ensuring the machine operates efficiently and avoids costly repairs.
Clean Refilling Tools
Before refilling the hydraulic system, ensure that all refilling tools—such as funnels, hoses, and containers—are thoroughly cleaned. Using contaminated tools can introduce dirt or other particles into the system, which can damage seals, clog filters, and reduce system performance.
Replace Oil Periodically
Hydraulic oil should be replaced after every 1,000 operating hours or in accordance with the manufacturer’s guidelines. Over time, oil loses its lubricating properties, which can lead to overheating, reduced efficiency, and accelerated wear on critical components. Regular oil changes are essential for maintaining the health of your bucking unit or breakout unit.
Use High-Efficiency Filters
Always use a high-efficiency filter (120 mesh or finer) when refilling the hydraulic system. This ensures that contaminants larger than 125 microns are removed, preventing the introduction of harmful particles into the system. Consider dual-stage filtration for critical systems to offer added protection.

Preventing Air and Moisture Ingress in Bucking Units and Breakout Units
Air and moisture ingress can cause a number of issues in the hydraulic system, from erratic actuator movement to corrosion of components. Preventing air and moisture from entering the system is key to keeping your bucking unit or breakout unit in peak condition.
Purge Air from the Hydraulic System
Air entering the system can cause irregular actuator movement or create cavitation noises in the pump. If you detect such signs, immediately shut down the equipment and purge the air from the highest points of cylinders, valves, and pipelines. Use dedicated air-release valves to remove air from the system efficiently.
Prevent Water Contamination
To avoid water contamination, store oil in a dry environment and tightly seal unused oil containers. In humid climates, regularly check for condensation in the oil tank. Water contamination can increase the acidity of the oil, leading to corrosion of cylinders, valve blocks, and other internal components. Replace water-contaminated oil as soon as possible to prevent serious damage.

Pressure Gauge Calibration for Bucking Units and Breakout Units
Accurate pressure readings are essential for maintaining the safety and performance of bucking units and breakout units. Incorrect pressure readings can lead to over-pressurization, which can damage components, or under-pressurization, which can cause poor machine performance.
Calibrate Pressure Gauges Regularly
Calibrate the pressure gauges of your bucking unit or breakout unit every six months, or after any abnormal pressure event. Use a certified reference gauge or digital calibrator to ensure the readings are accurate to within ±1% of full scale.
Error Management
If the gauge shows a deviation of more than ±2%, it should be replaced or repaired immediately. Inaccurate pressure readings can lead to operational issues, such as pump damage or inefficient machine performance.

Inspecting Seals and Wearable Components in Bucking Units and Breakout Units
Seals and wearable components like jaws in bucking units and breakout units are prone to wear and tear over time. Regular inspections and timely replacements are crucial to ensure smooth operation and prevent oil leaks.
Inspect Seals for Leaks
Visually inspect the seals around cylinder rods, pipe joints, and valve manifolds for any signs of oil leaks. If you notice any micro-leaks, use ultraviolet dye or leak detection sprays to identify the source. Replace cracked or hardened seals to prevent oil loss and environmental contamination.
Monitor Jaws for Wear
The jaws in bucking units and breakout units are subjected to significant stress and wear. Regularly measure the height of the jaw teeth with a caliper. If the wear exceeds 3mm, or if you notice cracks or dents, replace the jaws to ensure safe and efficient operation.

Lubrication and Anti-Corrosion Management for Bucking Units and Breakout Units
Proper lubrication and corrosion prevention are essential to maintaining the performance of bucking units and breakout units, especially when exposed to harsh environments like saltwater or chemicals.
Apply Anti-Rust Coatings
Exposed metal surfaces such as guide rails and bolts should be coated with NLGI Grade 2 lithium-based grease every 30 days. In extreme environments, such as offshore rigs, use corrosion-resistant coatings or stainless-steel components to protect these parts from rust and degradation.
Lubricate Moving Parts Regularly
Lubricate rolling friction points, such as bearings and cam followers, every 500 operating hours with high-temperature grease. For sliding friction points, such as piston rods and gear racks, apply a thin layer of molybdenum disulfide grease to reduce friction and prevent wear.
Keep a detailed lubrication log to track maintenance intervals and ensure your bucking unit or breakout unit remains in top condition.
