DNV bundle gas supplier — manifolded cylinder bundles for offshore duty
A DNV bundle gas supplier provides cylinders joined by a common manifold in one lifting frame, so a single connection delivers a large volume of gas.
REAL GAZ fills bundles with nitrogen, argon, oxygen, helium, hydrogen mixtures and calibration blends for offshore and heavy industry.
REAL GAZ fills bundles with nitrogen, argon, oxygen, helium, hydrogen mixtures and calibration blends for offshore and heavy industry.
Bundles relate to ISO 10286, EN ISO 11120 for large cylinders, DNV 2.7-1 frame practice and ADR / UN rules.
A bundle commonly holds 12 to 16 cylinders of 50 litres at 200 or 300 bar, giving several hundred cubic metres of gas from a single outlet. That capacity makes bundles popular for nitrogen purging and for long-running welding tasks. Because the stored energy is high, bundles must be lifted only by their designed points and secured in an upright position. REAL GAZ supplies guidance on connection sequences, leak checks and depressurisation, and can propose a regulator station sized for the flow your equipment needs. After use, depressurised bundles should be returned with valves closed and caps fitted, so that residual pressure is clearly recorded and the frame can be inspected before the next fill. Customers with several bundles on one site can ask for a simple rotation plan, so that older units are used first and no frame sits unused for long periods.
🏭 Where DNV Gas Bundles Are Used
- 🛢️ Pipeline pre-commissioning — nitrogen bundles purge and pressure-test lines before start-up;
- 🔩 Welding projects — argon and mixed shielding gas bundles feed multi-station sites;
- 🌊 Offshore utilities — instrument air backup and inerting rely on high-capacity nitrogen bundles;
- 🧪 Process plants — helium and calibration gas bundles support analyser rooms.
🔗 Bundle Design Notes
- manifold with isolation valves on each cylinder permits safe maintenance;
- a single outlet and pressure regulator simplifies connection to the user system;
- relief devices and protective caps limit risk during lifting.
