Title: Determining the velocity required to keep solids moving in pipelines
Category: Technical papers from the Journal of Pipeline Engineering
Downloadable: Yes 
Catalog No.: 2098
Date of Publication: March, 2007
Price: $25.00 US
Authors: Dr John S Smart
Abstract: KNOWING THE velocity required to entrain solids in pipelines during cleaning can be an important design parameter to avoid solids’ build-up in front of pigs that can stick the pig. Design information on the velocity required to entrain solids is presented for sediment and debris in pipelines such as iron sulphide, iron carbonate, black powder and sand is presented for various solids subject to a shape factor that can be used to estimate when progressive pigging, jetting devices or gel pigs are required to allow safe passage of pigs through a pipeline in oil in oil or water.
