What is the minimum speed in miles per hour for a scraper when cleaning a pipeline?

The minimum speed of 2 miles per hour for a scraper when cleaning a pipeline is based on the need for effective cleaning while minimizing the risk of damage to the pipeline. At this speed, the scraper is able to effectively dislodge and remove debris, sediment, or buildup from the interior walls of the pipeline without causing excessive wear or the risk of the scraper becoming stuck.

Speed below this threshold might not provide sufficient momentum for the scraper to do its job efficiently, potentially leading to incomplete cleaning or maintenance issues over time. Scrapers are essential for maintaining the integrity of pipelines, ensuring flow efficiency, and preventing blockages that can lead to more serious operational problems.
