Maintenance After Installation of Precision Tubes

‌Precision tubes are high-precision, high-finish seamless steel pipes manufactured by cold drawing or cold rolling processes. The inner and outer diameter tolerances can be controlled within ±0.05mm. They have both high mechanical properties and lightweight characteristics. They are mainly used in high-precision demand fields such as machinery manufacturing and the automotive industry. After the installation of precision tubes, a series of maintenance work is required to ensure their long-term stable operation and extend their service life. The following are some key maintenance work:

Daily inspection and maintenance

1. Appearance inspection

Regularly check whether there are scratches, dents, rust or other abnormal phenomena on the surface of the precision tube.

Use tools such as magnifying glasses to check surface defects such as cracks and folds.

2. Connection inspection

Check whether the connection parts such as joints and pipe flanges are tight to avoid leakage caused by looseness.

Ensure that the sealing ring is intact. If it is found to be aged or damaged, it needs to be replaced in time.

3. Functional test

Perform pressure tests regularly to ensure that the precision tube is leak-free within the working pressure range.

Check the flow performance of the precision tube to ensure that there is no blockage or poor flow.

Regular cleaning and maintenance

1. External cleaning

Use non-corrosive detergent and soft cloth to clean the surface of the pipe to prevent dust and dirt from wearing the pipe surface.

Avoid using hard objects or sharp tools to scratch the surface during cleaning.

2. Internal cleaning

Use special cleaning tools or equipment to clean the inside of the pipe to ensure that there is no residue in the pipe that affects the flow.

For precision tubes that are used for a long time, internal rust removal and anti-corrosion treatment should be performed regularly.

Anti-corrosion and anti-rust treatment

1. Anti-rust treatment

After cleaning, apply an appropriate amount of anti-rust oil or anti-rust grease to form a protective film to isolate air and moisture to achieve the purpose of rust prevention.

For precision tubes that require long-term anti-rust protection, vapor phase rust inhibitors, paint coatings or electrochemical anti-rust treatment methods can be used.

2. Anti-corrosion treatment

For precision tubes exposed to corrosive environments, appropriate anti-corrosion measures should be taken, such as coating anti-corrosion coatings and using corrosion-resistant materials.

Regularly check whether the anti-corrosion layer is intact. If there is any damage or aging, it should be repaired or replaced in time.

Storage and transportation maintenance

1. Storage environment

Ensure that the storage environment is dry and well ventilated to avoid corrosion of precision tubes in humid and high temperature environments.

During storage, it should be isolated from other metal materials to avoid mutual corrosion.

2. Transportation protection

During transportation, isolation and protection measures should be taken to prevent dust, oil, rust and other pollutants from contaminating the precision tubes.

Use appropriate lifting equipment and transportation tools to avoid scratches on the surface and damage caused by impact.

Records and adjustments

1. Establish maintenance records

Record the time, content, personnel, problems found and treatment methods of each maintenance.

Maintenance records help to detect potential problems in time and take appropriate measures to deal with them.

2. Adjust maintenance plan

According to maintenance records and usage, adjust maintenance intervals and plans in time.

For precision tubes with frequent problems or harsh usage environments, the maintenance cycle should be shortened and inspection efforts should be strengthened.

Summary

The maintenance work of precision tubes after installation involves many aspects, including daily inspection and maintenance, regular cleaning and maintenance, anti-corrosion and anti-rust treatment, storage and transportation maintenance, and record keeping and adjustment. Enterprises should formulate scientific maintenance plans and strictly implement them to ensure the long-term stable operation and extended service life of precision tubes.
