Nitrogen gas and its usage in Steel Plant IspatGuru

Jul 01, 2015Liquid nitrogen cooling properties are used to separate shrink fit bearings from the shaft. Conversely liquid nitrogen is also used for shrink fitting. In shrink fitting, instead of heating the outer metal part, the inner part is cooled by liquid nitrogen so that the metal shrinks and can be inserted.

N-Two Cryogenic Enterprise Inc. Our Services

We use liquid nitrogen to rapidly freeze virtually any diameter pipe and fluids such as water, glycol and some oils. Unlike other companies who use carbon dioxide (CO2), liquid nitrogen is colder and freezes faster. Most importantly, freezing pipes is a far faster process and better for the environment as it does not require draining.
