Nitrogen


What is Nitrogen?

Nitrogen (N2) is a versatile gas used across a wide range of applications and industries, and we’re always ready to supply it for new applications that arise. We offer nitrogen in multiple purities and supply modes.

Purchase High-pressure Nitrogen Gas or Liquid Nitrogen

We offer compressed and liquid nitrogen in various grades specific to different applications, such as:
• A coolant for concrete work
• An assist gas for laser cutting
• A pressurizing agent in pipelines
• A cryogenic for preserving biological material
• A welding gas in automotive manufacturing

Industrial Applications

Construction
For working with concrete in hot weather, our CryoCrete™ Concrete Cooling Systems use liquid nitrogen as an alternative to traditional cooling methods.

Manufacturing & Metal Fabrication
Nitrogen is used as an effective way to prevent oxidation and provides a safe, inert atmosphere that “sweeps” off gases produced by furnaces. It’s also used as an assist gas for laser cutting and enhances plasma cutting.

Energy
Nitrogen is used in a wide range of upstream and midstream energy applications. It can be used for everything from testing pipeline pressure to purging air to managing temperature to lightening liquids for better flow.

Chemicals
Nitrogen is used to pressurize pipelines in order to help propel liquids and to help purge piping and equipment to prevent contamination. Partnering with Priority Energy Services, we offer quality nitrogen backed by a constant, consistent supply from mobile nitrogen pumpers.

Healthcare
Vital to all sectors of the healthcare industry, nitrogen NF is a useful cryogen for freezing and preserving biological material.

Life Sciences
As a gas, nitrogen is used as an essential component in various life science processes as well as a protectant against oxidation and contamination. In liquid form, nitrogen is also used to achieve cryogenic temperatures in reactor cooling application.

Food Processing
From chilling to freezing, nitrogen plays an important role throughout the entire food packaging and preservation process. In addition to its cooling properties, nitrogen also increases shelf life for food products in modified atmosphere packaging (MAP), keeping oxygen out and freshness in.

Automotive
Nitrogen is used as both a safety component in airbags and as a versatile welding gas in automotive manufacturing. It’s used in a diverse range of assembly line tasks because it provides a good atmosphere for welding with any material. Nitrogen is also used in place of air in tires to maintain consistent pressure in fluctuating temperatures.

Aerospace & Defense
Using nitrogen while manufacturing quality components is a safe practice commonly used throughout the aerospace industry. An inert gas, nitrogen eliminates the presence of oxygen and secures a nonflammable environment. Nitrogen is also used in heat-treating furnaces, wind tunnels and laser-cutting applications.

Supply Modes

Cylinders & Liquid Containers
We offer nitrogen in high-pressure gas cylinders and liquid nitrogen dewars—available in a variety of sizes—to meet any and all low-volume needs.

MicroBulk
For those who have outgrown cylinders and dewars but lack the space for bulk storage, we offer nitrogen through Airgas MicroBulk—a safe, clean and efficient solution for higher-volume users.

Bulk Deliveries
Nitrogen is also available in bulk gas and liquid delivery—as well as in a full range of purities and tank sizes.

Pipeline
For those who regularly consume gas in large volumes, we offer pipeline supply systems—a more economical and reliable option to other supply modes.
