Steel Arch Support has undergone long-term operation and repeated start and stop, coupled with possible problems in the original design, manufacturing, installation, etc., the status of the pipeline Steel Arch Support will change. During the daily inspection, the hanger spring was crushed and emptied, the Steel Arch Support was insufficient in thermal displacement, the hanger was rusted, and the boom was skewed and loose. The existence of these problems will inevitably change the reasonable distribution of Steel Arch Support loads and deteriorate the operating environment of pipelines and units. At the same time, unreasonable stress distribution will lead to accelerated stress damage of the pipeline. If not treated in time, the service life of the pipeline will be shortened, which will pose a serious threat to the safe operation of pipelines and units.
To this end, the state of the pipeline Steel Arch Support is inspected, analyzed and adjusted to improve the operation of the pipeline and the unit Steel Arch Support to achieve safe operation and long service life.
