Preventing Premature Failure of Hydraulic Systems in Oil and Gas | MCE

Written by Motion & Control Enterprises, LLC (MCE) | Jan 20, 2024 5:00:00 AM


Premature failure of your equipment’s hydraulic system poses significant risks to the oil and gas industry—including unplanned downtime, costly repairs, environmental hazards, and compromised worker safety. 
 

You can’t eliminate corrosive elements from your work site, but you can minimize the damaging effects of corrosion and wear on your hydraulic systems.  

The Cost of Corrosion and Wear on Hydraulic Systems 

The total annual direct cost of corrosion in the U.S. oil and gas production industry is estimated at $1.4 billion. (AMPP) 

That’s an alarming number to consider. However, those costs are likely to rise even higher as exploration uncovers new hydrocarbon sources. The increasingly complex environments where oil resides can mean greater risk to your equipment.  

Oil rigs and fracking operations often encounter harsh conditions, including extreme rain, snow and temperatures. In some environments, temperature fluctuations from -50°F to 100°F, which put stress on equipment. 

Exposure to corrosive elements like salt water, sand and wind, or high-pressure environments deep underground, changing geological formations, hazardous gases and toxic chemicals also cause equipment failure. Ensuring replacements for fluid power components, such as hoses, fittings, and filtration systems, is critical due to the harsh conditions and corrosive elements of fracking and wellhead operations. 

Over time, the combination of these corrosive elements compromise the integrity of equipment, leading to:

  • Environmental impacts from leaks and spills 
  • Regulatory fines, litigation costs and public scrutiny 
  • Safety risks to employees 
  • Disrupted production schedules from unplanned downtime 
  • Higher repair and replacement costs 
  • Potential loss of revenue 

 

Increased risk, coupled with restrictive environments and limited opportunity for emergency repairs, means you need to minimize the potential for failure before it becomes a problem. 

Key Causes of Hydraulic System Failures in Oil and Gas Operations 

Often, corrosion problems go unnoticed due to a lack of awareness from management or those responsible for operation, inspection and maintenance. To promote awareness of premature failure conditions, train your employees to spot early warning signs of wear, rust, degradation or contamination and clearly outline next steps for alerting and addressing these issues.  

The Role of Contaminants in Accelerating Hydraulic System Failures 

Corrosion happens when the material used in a hydraulic hose assembly interacts with its environment and begins to degrade. These reactive elements are usually moisture, oxygen, salt or acids.  

The oil and gas industry is especially harsh on fluid power equipment due to the presence of hydrogen sulfide, a naturally occurring compound in crude oil and natural gas that poses both corrosive and safety risks. Hydrogen sulfide is acidic when dissolved in water, leading to localized pitting corrosion and uniform degradation of metal surfaces. 

The corrosion process starts when these reactive elements come into contact with the internal parts of the hose or the metal components.  

Signs of early corrosion include: 

  • Rust 
  • Leaks 
  • Dullness 
  • Scaling 
  • Pitting in material 
  • Reduced performance 
  • Damage to inner structure or outer surface coating 

The internal surfaces of hoses can corrode if hydrogen sulfide interacts with water or abrasive materials like sand in fracking operations. For valves and pumps, prolonged exposure to hydrogen sulfide and high pressures increases susceptibility to cracking and pitting. Filters can become compromised if the housing materials are not resistant to hydrogen sulfide corrosion or become clogged with sand and dirt particles. 

Once corrosion occurs in hoses and fittings, it can impact other system components, creating unwanted pressure changes, fluid flow constriction and hydraulic oil contamination—leading to decreased performance, increased wear on expensive machinery, and safety issues such as burst hoses leading to hydraulic injection injuries. 

High Abrasion in Oil and Gas: The Silent Hydraulic System Killers 

Applications such as drilling and hydraulic fracturing expose hydraulic systems to constant stress. This continued exposure increases degradation of components like hoses, fittings, seals, cylinders and valves.  

Some examples of high-abrasion applications in oil and gas include:  

  • Drill strings and hydraulic components in drill rigs exposed to abrasive drilling fluids and rock cuttings. 
  • Sand or ceramics mixed with fracturing fluid in fracking applications. 
  • Abrasive mixtures of mud (water, oil and solid) in mud pumps and circulation systems. 
  • Power tools that interact with abrasive debris. 
  • Mining or extracting equipment exposed to sandy or gritty materials. 

Under this constant stress, those components will eventually break down, usually at the worst time.  

3 Hydraulic System Wear Prevention Tips for Oil & Gas Industry 

Corrosion risk can’t be eliminated but it can be prevented.  

When a critical piece of equipment is offline due to an unexpected failure, it can have disastrous effects on a business’s ability to operate and generate revenue. That’s why we offer consultative training programs to help your crew learn how to address potential issues before they lead to failure.   

Prevent unplanned downtime from asset corrosion and abrasion by:  

  1. Selecting quality products made from appropriate materials and coatings. 
  2. Implementing a corrosion monitoring program (inspection, repair and replacement). 
  3. Having critical spares and inventory on hand for rapid repair. 

 

Choose High-Quality Hydraulic Materials for Longevity 

Choosing the right hoses, fittings and filtration systems constructed from the right material at the start can save thousands and prevent unnecessary downtime.  

We recommend choosing hydraulic hose components from the same product line.  

Hydraulic manufacturers work within a specific set of tolerances. Using a component from another manufacturing line decreases the likelihood of proper fitment and increases liability. If hydraulic hoses, fittings and seals are from different brands, the manufacturer may not honor their warranty on a failed component. 

At MCE, we carry a full line of Parker hoses and fittings designed to withstand high pressures, extreme temperatures and abrasive environments common in oil and gas applications.  

This ensures products are rated following Mine Safety and Health Administration (MSHA) guidelines and each system component is compatible and appropriate for the application. Staying within the same brand simplifies maintenance activities, asset tracking and communication for a more reliable and efficient system. 

Inspect, Repair and Replace Hydraulic Components 

Hydraulic systems operate under high pressure, and any leak, crack, or worn component can lead to potential hazards for workers and the environment.  

Regular inspections allow for early detection and preventative action. We can help your team develop proactive maintenance strategies to reduce those risks and create a maintenance program that covers the following areas: 

  • Kickstart a corrosion monitoring program (inspection, repair and replacement) to spot early signs of wear, rust or contamination to extend the lifespan of hydraulic components. 
  • Regularly check hydraulic fluid for contamination or degradation, plus verify system pressure and performance against application specifications.  
  • It may be time to replace if damage is extensive or the system has neared its service life. We help you select components properly rated for high pressures, temperatures and corrosive conditions.  

Note: For repairs, be sure to isolate the system, safely relieve pressure, and replace damaged components like seals, hoses, or valves using OEM parts to maintain compatibility. 

Don’t Overlook the Value of Filtration Systems in Healthy Hydraulics 

Filtration systems are your first line of defense against contaminants in your hydraulic assembly. Maintaining hydraulic fluid quality is essential to a healthy hydraulic system. Blockages or contamination in the hydraulic fluid can cause systems to lock up or component failure.  

Prevent contamination and ensure clean hydraulic fluid using proper filtration products that meet your assemblies' specific requirements. We recommend using Parker filters to maximize machine uptime, reduce maintenance costs and extend equipment life by preventing system contamination.
