Pig pushing

Nitrogen is regularly used for pigging applications like cleaning and inspection. APEX nitrogen is an inert environmentally friendly propellant that keeps pig traveling through pipelines at pressures and flow rates that meet clients’ needs.



Air Liquide’s Industrial Gas Services (IGS) division offers temporary, on-demand bulk nitrogen supply and mobile nitrogen pumping/vaporization units. For customers requiring a long-term supply of industrial gases, we provide a full range of on-site support services as well as iDATAL real-time vessel monitoring and reporting systems.
