Maintenance methods for mechanical tubes

Mechanical tubes are often referred to as the "vascular system" of industrial equipment, serving as essential components for transporting fluids and gases. They play a crucial role in industries such as petroleum, chemical processing, and machinery manufacturing. In oil fields, mechanical tubes facilitate the transportation of crude oil and natural gas. In the chemical industry, they ensure the safe transmission of various corrosive chemicals. In machinery manufacturing, they are indispensable for power transmission and medium supply within equipment.

Four Essential Steps for Mechanical Tube Maintenance

1. Daily Cleaning: Preventing Issues at the Source

Surface Cleaning: The surface of mechanical tubes can accumulate dust, oil, and other impurities. Using a neutral detergent and a soft cloth can help remove surface contaminants and maintain cleanliness.

Internal Unblocking: Critical pipelines, such as hydraulic lines, are susceptible to blockage due to impurities in the medium. Regular cleaning of internal deposits ensures unobstructed flow.

Environmental Control: To prevent corrosion, mechanical tubes should be kept away from direct contact with corrosive substances such as acids and alkalis. Maintaining a controlled environment helps extend their lifespan.

2. Regular Lubrication: Reducing Friction and Wear

Lubricant Selection: Choosing the appropriate lubricant, such as engine oil or gear oil, based on the type of pipeline is crucial. Special attention should be given to lubricating moving parts and connection points to reduce friction and ensure smooth operation.

Seal Maintenance: Seals should be inspected regularly for signs of aging or wear. Any damaged seals should be replaced promptly to prevent leaks.

Monitoring Performance: After lubrication, the system should be closely observed for abnormal vibrations or noises that may indicate potential issues.

3. Key Inspections: Preventing Potential Failures

Visual Inspection: Routine inspections should be conducted to identify cracks, deformations, or leaks, especially at welds and bends.

Pressure Testing: High-pressure pipes should undergo regular water pressure or air pressure tests to verify their ability to withstand operational pressures.

Leak Detection: Applying soapy water to pipe joints and observing for bubbles can help identify small leaks before they become major issues.

4. Proper Operation: Avoiding Maintenance Pitfalls

Avoiding Unnecessary Replacements: Minor faults should be repaired whenever possible instead of immediately replacing parts, which can lead to unnecessary costs.

Ensuring Proper Fit Clearance: Precision components, such as plunger pumps, should be assembled according to strict standards to maintain the correct fit clearance and avoid operational issues.

Checking Travel Allowance: The movement range of mechanical components should be regularly inspected to prevent excessive wear from reducing functional capacity and causing equipment failure.

Practical Tips for Extending the Lifespan of Mechanical Tubes

Moisture and corrosive substances accelerate the degradation of mechanical tubes. Applying a protective layer of anti-rust paint before the rainy season can effectively shield tubes from moisture and slow down the oxidation process. Additionally, raising stored tubes at least 10 cm off the ground prevents direct contact with damp surfaces and minimizes the risk of corrosion.

Vibration can weaken the internal structure of mechanical tubes, leading to reduced strength over time. Implementing proper vibration control measures, such as securing tubes with stabilizing supports, can help maintain structural integrity.

Promptly addressing defects is also essential. If the zinc coating on the tube surface is damaged or localized oxidation occurs, using specialized repair coatings can prevent further deterioration and extend the tube’s service life.

Conclusion

Proper maintenance of mechanical tubes involves a combination of cleaning, lubrication, inspections, and adherence to best operational practices. Preventive maintenance not only extends service life but also minimizes the risk of unexpected failures. Following standardized procedures and using appropriate tools ensures the efficient and stable operation of equipment. Keeping tubes clean prevents hidden dangers, timely lubrication reduces wear, regular inspections help detect early signs of damage, and scientific operation enhances overall safety and reliability.
