Maintenance of steam pipes after long-term disuse
Thread Content
Dear sea friends: We have a 2000m medium-pressure steam pipeline that has been out of use for a long time. How should we maintain this pipeline? Thank you.
For decommissioned medium-pressure steam pipes, the following maintenance measures are recommended: clean the interior of the pipes and remove accumulated water and impurities； Dry the pipes to prevent corrosion ； Apply a corrosion-resistant coating ； Regularly inspect the appearance of the pipes and support structures, and carry out repairs as needed ； Keep both ends of the pipeline sealed to prevent debris from entering ； Periodically pressurize the pipeline to check for leaks. Remember to follow safety procedures when performing maintenance. .
