The cleaning of hydrocarbon pipelines, and if necessary the analysis of any faults in such, can be effectively performed using a particular device called a "pig", which is pushed along the pipeline using a controlled flow of fluid such as nitrogen which, compared with other fluids (water, air, chemicals), is more chemically inert, contains a very limited residual content of water, and displays very òimited interaction with products normally present in the pipeline. Through special launch and recovery stations, the highly pure nitrogen, which has a very low dew point so as to produce an anhydrous environment, is pumped at high pressure, sending the pig along the pipeline even in the presence of curves or gradients. Using nitrogen, the pig can perform several fundamental tasks including "washing" the pipeline with gaseous nitrogen,

This technique can be adapted to many types of pipeline, and can be used during the various operational phases of the pipeline, from commissioning to ordinary and extraordinary maintenance.
