Nitrogen Pumping Services Through Coiled Tubing Our nitrogen pumping units support coiled tubing operations by assisting in underbalanced milling or cleanout operations and coiled tubing purging. This includes injecting nitrogen to displace fluids from the well bore and potentially dangerous gasses from pipelines and pressure vessels. In addition nitrogen pumps are perfect for standalone applications including N2 cleanouts and purging, well kick-arounds, nitrified acid assissts, foam cementing assists, UBD assists, pressure testing vessels, stored fluids withdrawal, pipeline pigging, and facility purging.
