Maintenance and care for pressure pipelines

At Haihao Group, as experts in piping systems, we not only provide reliable piping products but also excel in maintenance practices for various pipeline systems. Proper maintenance and care are essential for pressure pipelines to ensure their safety, performance, and longevity. Pressure pipelines operate under external forces, conveyed media, and environmental factors, which can cause deformation, wear, corrosion, leaks, and vibration over time. Regular maintenance is critical to mitigate these risks and maintain optimal performance. Below are key maintenance practices for pressure pipelines:

prefabricated products

1.Inspect Protective Measures

Regularly check the pipeline’s protective coatings and measures to ensure they remain intact. This helps minimize surface corrosion and prolong the pipeline’s lifespan.

2.Maintain Valves

Remove rust and apply lubricants to valve operating mechanisms periodically. Conduct regular operations to ensure smooth and flexible functionality.

3.Service Safety Valves and Pressure Gauges

Keep safety valves and pressure gauges clean and functional by wiping them regularly. Ensure timely calibration to maintain sensitivity and accuracy.

4.Check Fasteners

Inspect bolts for completeness, corrosion, and thread integrity. Ensure secure and reliable connections.

5.Monitor and Mitigate Vibrations

Pay attention to pipeline vibrations. If abnormal vibrations occur, take measures such as isolating vibration sources or reinforcing supports. Address friction points promptly.

6.Ensure Proper Grounding

Inspect static grounding and bonding devices for damage and repair them immediately to maintain proper functionality.

7.Maintain Idle Pipelines

For unused pipelines, purge the internal medium, and replace, clean, and dry them as necessary. Protect with inert gas if required. Apply protective coatings to the outer surface and inspect insulation materials for integrity.

8.Focus on High-Risk Areas

Inspect areas prone to corrosion or wear, such as pipeline-support contact points. Take corrective measures as needed.

9.Eliminate Leaks

Promptly address leaks or seepage in the pipeline system to ensure operational safety.

10.Thermal Tightening of Bolts

For high-temperature pipelines, tighten flange bolts during startup and temperature increase. For low-temperature pipelines, perform bolt tightening during cooling.

11.Avoid Improper Use of Pipelines

Do not use pipelines or their supports as grounding points for welding, anchoring tools, or as supports for lifting heavy objects.

12.Conduct Regular Inspections

Coordinate with inspection personnel for regular pipeline inspections. Prioritize maintenance for:

Pipelines in critical production areas.

Pipelines crossing roads, bridges, rivers, or residential areas.

Pipelines transporting flammable, explosive, toxic, or corrosive media.

Pipelines under harsh operating conditions or subjected to cyclic loading.

Proper maintenance of pressure pipelines ensures operational safety, reduces risks, and extends service life.
