Nitrogen Services Nitrogen Propelling of ILI Tools  Superior utilizes electronic data recording along with pressure regulation and flow controls to establish a steady state inlet and discharge flow when propelling ILI tools with nitrogen. The combined process of these controls along with Superior's extensive pumping experience and qualified personnel minimize velocity excursions resulting in a consistent high quality of data.Pressure regulation equipment insures a constant line pack pressure. The nitrogen pumping equipment is brought on line and a steady state flow is established through the line. When steady state flow conditions are reached the ILI tool is released into the steady state flow stream. Monitoring and recording of rates and pressures is conducted continuously throughout the tool run ensuring a smooth and more consistent velocity. This monitoring record is incorporated into the final report. Nitrogen Purging and Plant Services Purging Services Nitrogen inert, lowering explosive limits or purging is the replacement of an atmosphere of undesired composition in an enclosed vessel with another atmosphere of preferred composition. The atmosphere preferred is typically an inert gas, such as nitrogen. Purging is typically required to prevent fire or explosions where flammable or explosive materials are present. Purging is also required to avoid unwanted reactions between materials being handled and the atmosphere.  Plant Services Precision pressure, temperature and inventory control are required in many applications throughout the industrial segment. Nitrogen is used to perform inert, drying and power services on a daily basis. Each use of nitrogen requires a certain property and expected benefit within the processing segment. Some typical applications of Superior's mobile pumping units within the processing segment are:
