Technical Gas Ar-N₂ Blend — dependable argon-nitrogen for everyday production
A Technical Gas Ar-N₂ Blend from REAL GAZ is a cost-effective argon and nitrogen mixture intended for production and maintenance work where certified analytical accuracy is not required, but reliable and repeatable composition still is.
Technical blends are supplied dry, oil-free and filled to a declared nominal composition, ready for use in shielding, purging and atmosphere applications.
Technical blends are supplied dry, oil-free and filled to a declared nominal composition, ready for use in shielding, purging and atmosphere applications.
Technical blends are filled into cylinders built to ISO 9809 and inspected to EN 1968, with purity control suitable for production and maintenance duties.
The usual technical range covers argon with 2%, 5%, 10% and 20% nitrogen, supplied in 20, 40 and 50-litre steel cylinders at 200 bar and in bundles for sites with larger consumption. Composition is controlled by partial-pressure or weighed filling and checked by a quick analytical test rather than a full certificate programme, which keeps the cost lower. If your procedure sets a limit on moisture or oxygen content, tell us the limit and we will confirm the grade of base gas that meets it.
🏭 Where Technical Ar-N₂ Blends Are Used
- 🔧 Pipe and tank purging — the inert blend displaces air from pipework before and during welding, protecting the root side of stainless joints;
- 🏭 Annealing and brazing — low-oxygen atmospheres reduce scale and discolouration on parts passing through furnaces;
- ⚡ Electrical equipment — switchgear and cable-testing teams use inert technical gas for pressurising and flushing enclosures;
- 🛠️ General fabrication — workshops keep one dependable cylinder on the shop floor for tasks that do not justify a certified standard.
💡 Why Choose REAL GAZ
- ✅ Economical choice — declared-nominal filling keeps cost down where an analytical certificate is not required;
- 🧪 Consistent from batch to batch — controlled filling procedures hold composition steady, so process settings do not need re-tuning;
- 🎯 Easy to specify — give us the nominal nitrogen percentage and cylinder size; we confirm the blend and fill it;
- 🔒 Safe, inert contents — argon and nitrogen are non-flammable and non-toxic, though they displace oxygen, so storage areas need good ventilation;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- dry, oil-free filling lines;
- controlled filling to declared nominal;
- spot analysis of oxygen and moisture;
- leak testing and valve inspection.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
Because technical blends are often used in workshops, secure cylinders with chains or in trolleys and keep valve caps fitted during transport. Do not use the gas for breathing, and make sure confined spaces such as tanks are ventilated and monitored whenever inert gas is being purged into them.
