Discussion on the purging and design details of long-distance pipelines
Thread Content
1. Long-distance pipeline (approximately 5 km), with a relatively large diameter, but less than 600; purged with air. Question: Due to the large elevation differences along the entire length of the pipeline, is it necessary to purge it in sections before ascending? 2. For the same long-distance pipeline, are measures for dredging necessary in the design?
Dredging is necessary. As for what exactly needs to be transported and what the requirements of the process are, each case should be handled on a case-by-case basis
Dredging is necessary, right? Otherwise, purging will be time-consuming and labor-intensive, and it is also necessary to determine it based on the medium transported through the process pipelines as well as the required standards. If there’s no iron left, then more care must be taken during purging.
