DNV gas cylinder manifold — offshore-ready manifolds with robust, traceable components
A DNV gas cylinder manifold must perform reliably in the conditions covered by offshore container rules, where vibration, spray and lifting loads are routine.
REAL GAZ supplies manifolds with heavy-duty body, forged connections and pigtails rated for the same gases and pressures as your cylinders.
REAL GAZ supplies manifolds with heavy-duty body, forged connections and pigtails rated for the same gases and pressures as your cylinders.
The range is designed with EN ISO 7291, ISO 10297 and ISO 15001 for oxygen compatibility, aimed at offshore and shipyard use.
Where inspection records are demanded, we can supply 3.1 material certificates for bodies and fittings, test reports for each assembled manifold and a serial-numbered label. Gauge ranges are chosen to read in the middle third of the scale at normal operation, which helps crews spot a falling bank pressure early.
Handling guidance: a manifold installed on a moving platform needs shock-proof gauges, secured pigtails and clear identification of each gas. Walkways should remain free of hoses, and spare regulators should be stored in sealed bags. We can add a laminated line diagram so that new crew members understand the layout in minutes.
🏭 Where DNV Cylinder Manifolds Are Used
- ⚙️ Drilling and wellhead support — manifolds feed cutting and welding sets that keep maintenance work moving during platform shutdowns;
- 🔬 Offshore laboratories — gas chromatographs and mud-logging analysers receive stable carrier and calibration gases;
- 🏥 Medical bays on installations — oxygen manifolds back up the on-board treatment room with a regulated, alarmed supply;
- 🚀 Shipyards and fitting-out quays — racks of shielding gas supply hull and pipe welders working around the clock.
💡 Why Choose REAL GAZ
- ✅ Material certificates — body and fitting material records can be provided so inspectors can trace each part;
- 🧪 Oxygen-clean build — oxygen units are degreased and sealed in bags to remove hydrocarbon contamination;
- 🎯 Right-sized outlets — 1/4 inch to 1 inch outlets match the downstream line, avoiding adaptor stacks;
- 🔒 Overpressure protection — relief valves with piped vents protect pipework if a regulator fails;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- PMI checks on stainless components where specified;
- pressure testing to 1.5 times working pressure;
- electro-polished or passivated surfaces on request;
- final inspection with a documented pack.
Cylinders comply with ADR / UN transport rules and ISO 9809 design, with colour coding to EN 1089-3.
