Marine Diving Gas Cylinders Supplier - Gas Systems

Marine diving gas cylinders are high-pressure containers designed to store breathing gases like oxygen, nitrogen, or helium for underwater use. Gas systems in diving manage the blending, storage, and delivery of these gases to ensure safe and efficient breathing at various depths. These systems are critical for technical, commercial, and military diving operations.

Marine Diving Gas Cylinders and Gas Systems typically include the following key specifications and technical properties:

Size: Common sizes range from 3L to 18L, with larger systems available for commercial diving.

Grade: High-pressure cylinders are typically manufactured to DOT 3AA, ISO 9809-1, or EN 1964 standards.

Viscosity: Not directly applicable to cylinders, but gas mixtures (e.g., Nitrox, Trimix) have specific flow characteristics.

Buoyancy: Negative buoyancy when filled; buoyancy compensators (BCDs) adjust diver buoyancy.

Material: Typically aluminum (6061-T6) or steel (high-tensile grades like 4130).

Pressure Rating: Common working pressures include 200 bar, 232 bar, and 300 bar.

Valve Type: K-valve (yoke) or DIN valve configurations.

Corrosion Resistance: Aluminum resists saltwater corrosion; steel cylinders require protective coatings.

Weight: Varies by material—aluminum cylinders are lighter but bulkier than steel.

Regulator Compatibility: Must match valve type (yoke or DIN) and gas mixture.
