Maintenance Pigging Strategies

"What kind of pigs should I use?” “How often should I pig?” These are common questions related to maintaining a clean pipeline. Historically crude oil lines were often pigged more regularly than natural gas lines, but not anymore.

With more and more wet gas systems in play, sweeping liquids has become as critical as cleaning paraffin out of oil lines. No matter what kind of lines you are maintaining, an effective maintenance program starts with knowing your line and selecting the proper pig. Drinkwater Products will help you in this process and can lay out a recommended strategy based on over 25 years of maintenance pigging experience.

It's most important to track your pigs when there is a concern about a pig becoming stuck in the pipeline, which can occur during the commissioning of a newly constructed pipeline or when working on a line that has been infrequently pigged
