APPLICATIONS
When maintaining pipeline operations, gases like butane, ethane, propane, ammonia, oxygen, and nitrogen play crucial roles. Butane, ethane, and propane are transported and used as fuel sources. Ammonia acts as a refrigerant to prevent hydrate formation in natural gas pipelines. Oxygen is used for welding and cutting during maintenance. Nitrogen is employed for purging and pressure testing to ensure pipelines are contaminant-free and leak-proof. These gases ensure efficient, safe, and reliable pipeline operations.

Pipeline services involve the use of industrial gases for various operations related to the maintenance, testing, and commissioning of pipelines. These services ensure the integrity, safety, and efficient operation of pipelines used in industries such as oil and gas, petrochemical, and utilities.
Common industrial gases used in pipeline services include nitrogen (N₂), helium (He), and carbon dioxide (CO₂). These gases are used for purging, inerting, leak detection, pressure testing, and cleaning.
Pipeline purging involves the removal of undesirable gases or vapors (such as air, moisture, or hydrocarbons) from the pipeline by displacing them with an inert gas like nitrogen. This is crucial for preventing oxidation, corrosion, and potential explosive hazards during pipeline operations.
Nitrogen is used for purging, inerting, pressure testing, and pipeline drying. Its inert properties make it ideal for displacing oxygen and moisture, thereby preventing oxidation and corrosion within the pipeline.
Helium is commonly used for leak detection due to its small atomic size and low viscosity, which allows it to easily escape through small leaks. Helium leak detection involves pressurizing the pipeline with a helium mixture and using sensitive detection equipment to locate any leaks.
Yes, CO₂ can be used for certain pipeline services such as purging and pressure testing. Its ability to displace air and inert environments makes it useful for preventing oxidation and ensuring the integrity of the pipeline.
Benefits include improved safety, higher precision in leak detection, reduced environmental impact, and enhanced efficiency in pipeline maintenance and testing operations. Industrial gas-based services also offer faster and cleaner solutions compared to traditional methods.
Industrial gas solutions for pipeline services are provided by specialized gas suppliers, such as WestAir as well as companies specializing in pipeline maintenance, testing, and engineering services.
