Technical Gas Helium — industrial helium for leak testing and welding
Technical Gas Helium from REAL GAZ serves workshops and plants that need an inert, very light gas with high thermal conductivity. Helium does not react, does not condense above about −269 °C and diffuses quickly through the smallest leak paths.
We supply it at purity levels of 99.996 % and 99.999 %, filled to 200 bar in standard steel cylinders and in bundles for larger demand.

REAL GAZ supplies this product according to EN ISO 14175 for shielding gas, ISO 9809 cylinder rules and ISO 17025 analytical practice, suitable for industrial use.
🏭 Where Technical Helium Is Used
- 🔍 Leak testing — mass spectrometer leak detectors identify defects in tanks, heat exchangers and refrigeration circuits;
- 🔥 Arc welding — helium or argon–helium mixtures raise heat input for aluminium, copper and thick sections;
- 🧯 Purging and blanketing — inert displacement of air in sensitive process lines;
- 🎈 Lifting and inflation — balloons and weather probes benefit from the low density of the gas.
💡 Why Choose REAL GAZ for Helium
- ✅ Stable availability — helium is a finite resource and we plan stock to protect regular customers;
- 🧪 Defined purity — oxygen, moisture and nitrogen content are checked on delivery;
- 🎯 Practical packaging — single cylinders, racks and bundles fit the shop floor;
- 🔒 Efficient use advice — recommendations on regulators and flow rates reduce waste;
- 📄 Certificate of Analysis (CoA) — supplied with every order
🔬 Quality Control & Safety
- purification of the source helium;;
- analysis of oxygen, moisture and hydrocarbons;;
- controlled filling pressure;;
- valve outlet and leak testing.
Helium is not toxic but displaces oxygen, so use it in ventilated areas and secure cylinders against falling.
Cylinders comply with ADR / UN transport rules (UN 1046) and relevant EN/ISO standards.
📦 Grades & Packaging
Helium is sold in several purity grades, and technical users should select the one that fits the duty. Grade 4.6 is sufficient for balloon filling and most shop use, while Grade 5.0 is preferred for leak detection and welding mixtures where moisture and oxygen matter. Because helium atoms are so small, check threads and seals on every connection and use a regulator rated for 200 bar.
- 50 litre cylinders at 200 bar for workshop use;
- cylinder bundles for continuous consumption;
- stainless regulators for leak detector service;
- helium and argon blends available for welding on request.
Helium supply has been tight in recent years, so efficient use is sensible. Fit a flow meter, close valves between jobs, test fittings for leaks before opening the cylinder fully, and recycle helium where the process allows. REAL GAZ can advise on practical measures that cut consumption.
