The routine maintenance of finned tubes is an important basis to ensure and extend the life and avoid accidents. Without normal maintenance, finned tubes will not only leak, but also explode under high pressure, causing huge losses. Therefore, the maintenance of finned tubes is very important. So how should finned tubes be maintained?

1.Carefully check the protection measures of the finned pipe path to ensure that it is not damaged and to reduce the corrosion on the surface of the pipe. If corrosion is found, clean the surface of the pipe in time.

2.The operating mechanism of the valve is often descaled and operated regularly to ensure its flexibility of operation. After rust removal, pay attention to check and observe whether the valve is stuck.

3.The safety valve and pressure gauge should be wiped frequently to ensure correct sensitivity and checked on time. If contaminants are found, remove them in time.

4.Check the solidity of fastening bolts regularly to ensure that the fastening bolts are intact, corrosion-free, and the fastening is complete and reliable.

5.Pay attention to the vibration of the pipeline. If abnormal vibration is found, take vibration damping measures such as cutting off the vibration source and strengthening support. If friction is found, take immediate measures.

6.Electrostatic jumper and grounding device to maintain good integrity, and repair damage found in time to ensure the stability and safety of the circuit power supply.

7.Please remove the internal media from the stopped finned tube, replace, clean and dry, and protect with inert gas as needed. Please pay attention to the protection of paint on the outside and make sure the insulation material of the insulation pipe is clean to avoid the corrosion of the finned pipe.

8.Check the contact parts such as pipes and brackets. It is easy to corrode and wear, and take measures immediately if problems are found.

9.Eliminate the running, bubbling and leakage of piping system in time.

10.For high-temperature piping, it is necessary to heat tighten the fastening bolts of the pipe flanges at the beginning of heating. For low temperature pipeline, cold tightening should be done during the cooling process.

11.It is strictly forbidden to use the pipe and bracket as the anchor and support point for lifting the tools such as welding zero wire.

12.Assist finned pipe circuit inspectors to inspect the pipes regularly.

13.Finned pipes in important parts of the production process, roads, bridges, railroads, rivers, finned pipes across residences, finned pipes carrying explosive, toxic and corrosive media, pipes with strict working conditions and pipes with alternating loads should be maintained and inspected.

14.In case of abnormal conditions during operation, take immediate emergency measures and report to the relevant management and management personnel in a timely manner.
