The Oil & Gas Industry (Oil & Gas Industry) is an industry that requires large quantity of industrial and specialty gases throughout all production phases (upstream, midstream, downstream).

The gases used in metal welding and cutting need to be highly pure to ensure the best weld and cut quality, minimize waste, and improve productivity. The choice of cutting method depends on various factors, such as laser cutting, plasma cutting, or oxy-fuel cutting, each with its own advantages. Laser Welding and Cutting Gases Laser [...]

Modified Atmosphere Packaging (MAP) is widely used in the food industry to extend shelf life and preserve the quality of food products. This technology involves packaging food in materials that restrict gas exchange, creating a modified atmosphere inside the package. By altering the gas composition, MAP inhibits the growth of spoilage agents, thus maintaining the [...]

Calibration gases are essential for monitoring and controlling exhaust emissions to protect the environment. In the context of alarming environmental pollution, various forms of pollution—air, water, soil, noise, heat, light, and visual pollution—pose severe challenges, with air pollution being the most critical issue. The world is gradually suffering the dire consequences of air pollution. The [...]

When it comes to diving, the first thing that often comes to mind is the oxygen tank worn by divers. Typical diving gases are mixed using a blend of Oxygen, Nitrogen, and Helium. Depending on the required depth, the tank’s gas mixture is adjusted.  Common diving gases include: Compressed Air: Used for depths < 40m [...]

Helium leak testing is widely used in various industries due to Helium’s ideal properties. Helium is non-toxic, non-flammable, and has a small atomic size that allows it to pass through even the smallest leaks. It can be mixed with other gases, like nitrogen, to reduce costs and improve detection efficiency. This technology is crucial for [...]

Calibration gases play a crucial role in the calibration of gas detectors. They establish the relationship between measurement standards and measuring instruments, allowing the evaluation of errors and technical characteristics of devices. Calibration results help determine whether a device can continue to be used reliably. In industrial production, the presence of toxic and asphyxiating gases [...]
