Here at Pipeline Research, we have spent a great amount of time working with pigging from a specialist’s standpoint, approaching the subject in a scientific manner, using models, observation and analysis to provide insight to the motion and function of the pig. It is through this research and scientific approach that we are able to provide our services to enable more effective pigging, pipeline dewaxing, safer passage of pigs through pipelines and provide innovative solutions to the variety of challenges faced in pipelines and pig use.
Pigs are often used for pipeline commissioning, cleaning, filling, batching and monitoring, as well as pipeline dewaxing. With the presence of paraffin’s in crude oil or condensate, wax deposition can occur on the walls of sub-sea pipelines as they cool, restricting and thus slowing the flow through the pipe. Using guide discs or seals the pigs are able to scrape off wax from the inside of the pipe wall, however this can lead to build up of a critical volume of wax ahead of the pig and the friction required to move the plug can be too great for the pressure available, which blocks the pipeline
We make use of the bypass pig model to ensure that pipeline dewaxing is able to go off smoothly, operating on the “Continuity Principle”, which states that “In order to avoid a solid build of wax ahead of the pig, then the rate of bypass through the pig should be greater than the rate of build-up of wax in front of the pig”. This allows estimation of the pig bypass design and pigging frequency. To find out more about our pipeline dewaxing solutions, please don’t hesitate to get in touch with us.
