Seamless steel pipe maintenance

Seamless steel pipe maintenance

Seamless steel pipe in daily use needs regular maintenance  to extend its service life and ensure performance, the following is the maintenance of seamless steel pipe need to pay attention to the main points:

1. Anti-corrosion maintenance

Coating protection: For seamless steel pipes that are often exposed to air and moisture, anti-corrosion paint or coating can be applied on the surface to reduce oxidative corrosion.
Galvanized processing: You can choose the galvanized process, especially galvanized seamless steel pipe is more suitable for high humidity environment, such as underground pipes, water pipes, etc., to prevent its corrosion and reduce its service life.

2. Cleaning:

Clean up dirt and oxidation: The surface of the steel pipe can be rinsed with water to remove dust, dirt and other dirt on its surface. When removing the oxide layer on the surface of the steel pipe, it should be treated according to pickling passivation, and then cleaned by electrolysis
Dry surface: After cleaning the pipe, the pipe surface should be kept dry to prevent the residue after pickling from corroding the pipe.

3. Inspection and maintenance

Regular inspection: The appearance of the seamless steel pipe is checked to check whether the wall of the seamless steel pipe is thinner, whether there is a crack or rust. The thickness of the tube wall can be checked by ultrasonic flaw detector and other instruments.
Timely repair: If cracks, corrosion points or wear are found, they should be repaired in time to prevent expansion and thus affect the overall strength of the steel pipe.
Pressure test: For the pipeline system that needs pressure, pressure test should be carried out regularly to check whether the seamless steel pipe meets the pressure requirements.

4. Maintenance in use

Avoid overload: When using seamless steel pipe, it should avoid exceeding its maximum bearing limit. To avoid damage to the steel pipe.
Avoid external impact: seamless pipe in transportation, installation and use should avoid being subjected to a large impact to prevent seamless pipe deformation or damage.
Secure installation: Ensure that the seamless pipe is firmly installed in use to avoid vibration and displacement, which can cause fatigue and damage to the steel pipe.

In summary:

The daily maintenance of seamless steel pipes are mainly anti-corrosion, cleaning and regular inspection. By doing these work, the service life of seamless steel pipe can be effectively extended and its safety and reliability can be improved.
