Nitrogen N₂ - B20
A Nitrogen (N₂) B20 gas cylinder is a medium-to-large industrial gas cylinder with a water capacity of 20 liters, filled with nitrogen under high pressure (200 or 300 bar).
Nitrogen is stored in this cylinder as a high-pressure gas. Because nitrogen has no liquid phase at room temperature, the pressure on the manometer drops linearly as the cylinder empties. The B20 is a popular choice for users who want a substantial gas supply but still value a degree of portability within a working environment
Key features:
- Inert (non-reactive): Nitrogen hardly reacts with other substances under normal conditions, making it extremely suitable for preventing oxidation, fires, or explosions.
- Colorless, odorless, and tasteless: The gas cannot be sensed, which means that additional safety measures (such as oxygen alarms) are necessary in confined or small spaces.
- Non-flammable: Nitrogen does not support or feed combustion in any way.
- Asphyxiant (displacing): In high concentrations, the gas displaces the available oxygen, posing a direct risk of suffocation.
- Cylinder color coding (Indication): According to the European standard (EN 1089-3), the shoulder of a nitrogen cylinder is always marked in black.
Product details
Nitrogen N₂ gas cylinder, filled with 20L of N₂, specially developed for heavy industrial applications. It can be used to prevent oxidation, corrosion, fires, or explosions through an inert action, and ensures reliable performance during demanding processes such as purging pipelines, pressure testing, and inerting (developed for long-term and professional use).
Transport
Transport & Use:
- Fixation: Due to its weight and size, vertical fixation with ratchet straps or a sturdy cylinder holder in a vehicle is mandatory. Ensure the cylinder can never slide or tip over.
- Transport documentation: For commercial transport, the UN code (UN 1066, Nitrogen, compressed, 2.2) is important. Ensure your vehicle complies with safety regulations for transporting hazardous materials (ADR).
- Storage: Preferably store cylinders in a dry, well-ventilated room and protect them from direct sunlight and extreme temperatures.
Information
Safety
Specific safety information for Nitrogen (N₂):
- Asphyxiation hazard (Priority 1): A B20 cylinder contains a significant amount of nitrogen gas. A leak in a closed or moderately ventilated room displaces oxygen in the air unnoticed. Good ventilation is always required.
- High-pressure system: The cylinder is under high pressure (200/300 bar). Ensure that the pressure regulator and hoses are correctly coupled and suitable for the respective inlet pressure.
- No freezing issues: Because nitrogen is a gas under pressure (and not a liquid in the cylinder like CO₂), the valve is less susceptible to freezing at normal flow rates.
- Valve safety: The valve is the most vulnerable point. Always use the protective cap during transport or storage.
