Line or Vessel Drying

Industrial gases for drying piping, vessels, and equipment

Nitrogen is a clean, dry, inert gas and has long proven effective at displacing oxygen in tanks, hoses, and piping. Blanketing with nitrogen reduces the potential of combustion, maintains a positive pressure in storage tanks and prevents vaporization and loss of product to the atmosphere.

For decades, customers have relied on Air Products' APEX Services to provide a safe, reliable, and fast temporary supply of high-quality nitrogen to dry process equipment, including piping systems, heat exchangers, reactors, and molecular sieve beds with ambient or hot nitrogen. You can save time and money by safely and economically meeting your nitrogen needs over a wide range of pressures and flow rates with APEX Services.
