50L Oxygen Cylinder Capacity and Dimensions
The 50L designation refers to the cylinder’s nominal water capacity, not to 50 litres of gaseous oxygen. The amount of oxygen contained in a compressed gas cylinder depends on the filling pressure, temperature, gas conditions, and applicable filling requirements.
The referenced cylinder has an outside diameter of approximately 229 mm and an overall height of approximately 1485 mm. The approximate cylinder weight is 56 kg before variations caused by the final valve, cylinder design, manufacturing tolerance, and other configuration requirements.
For applications where cylinder dimensions, transport weight, pallet quantity, or storage layout are important, buyers should confirm the final dimensional drawing and packing configuration before placing an order.
CGA 540 Oxygen Cylinder Valve
The CGA 540 valve is a valve connection used for oxygen gas service in North America and other markets using compatible CGA connections. It provides the connection between the compressed oxygen cylinder and compatible oxygen regulators, filling equipment, and gas supply systems.
When selecting a CGA 540 oxygen cylinder, the valve connection should be matched with the regulator, filling equipment, and local gas-service requirements. Valve material, outlet configuration, thread specification, pressure rating, and oxygen-service compatibility should be confirmed before use.
CGA 540 Valve Selection Considerations
- Confirm that the regulator is designed for a compatible CGA 540 connection.
- Confirm oxygen-service compatibility of the valve and connected equipment.
- Check the required working pressure and applicable pressure rating.
- Confirm the valve configuration required by the destination market.
- Verify filling equipment compatibility before ordering bulk quantities.
DSW can discuss different valve configurations according to the cylinder design, destination market, customer specification, and applicable production requirements. Please provide the required valve standard and connection when requesting a quotation.
34CrMo4 Seamless Steel Oxygen Cylinder
This oxygen cylinder is manufactured from 34CrMo4 seamless steel, a high-strength alloy steel commonly used for seamless compressed gas cylinders. The seamless construction provides a continuous cylinder body without a longitudinal welded seam and is intended for high-pressure compressed gas applications when manufactured, tested, and certified according to the applicable requirements.
Material selection is an important consideration for compressed oxygen cylinders because the cylinder must withstand the specified pressure and remain suitable for its intended gas service. The final cylinder material, heat treatment, wall thickness, manufacturing process, and inspection requirements should comply with the applicable cylinder standard and certification.
For commercial orders, buyers can specify the required material, cylinder capacity, working pressure, valve configuration, applicable standard, markings, and documentation during the quotation stage.
Oxygen Cylinder Manufacturing and Quality Control
Seamless oxygen cylinders are pressure vessels that require controlled manufacturing, inspection, and testing. For B2B orders, the cylinder configuration should be confirmed against the applicable technical specification and destination-market requirements before production.
Key Manufacturing and Inspection Considerations
- Seamless steel cylinder body construction
- Specified cylinder material and heat-treatment requirements
- Dimensional and visual inspection
- Pressure testing according to the applicable requirements
- Valve installation and connection verification
- Cylinder marking and identification
- Applicable inspection and certification documentation
- Export packaging and pallet configuration where required
The exact production and inspection procedures depend on the selected cylinder design, applicable standard, certification requirements, and customer specification. Buyers should confirm the required documentation before placing an order.
Oxygen Cylinder Standards and Certification
Oxygen cylinders are pressure vessels, so manufacturing and testing requirements are more important than appearance alone. Depending on the target market and order requirements, DSW can discuss cylinders manufactured according to applicable international or regional standards.
The referenced cylinder configuration can be supplied according to applicable ISO 9809-1 requirements where specified. The exact standard, certification, cylinder marking, inspection, and testing requirements should be confirmed according to the destination country and customer’s technical specification.
This cylinder is part of DSW’s range of seamless steel gas cylinders, which are available in different capacities, pressure ratings, and valve configurations for compressed gas applications.
For export orders, buyers should provide the required certification or regulatory requirements during the quotation stage. This allows the cylinder design, valve configuration, markings, documentation, and inspection requirements to be confirmed before production.
Applications of 50L Oxygen Cylinders
Compressed oxygen cylinders are used where oxygen needs to be supplied in portable high-pressure form. The suitability of a cylinder for a particular application depends on its certification, gas grade, valve configuration, pressure rating, and applicable local regulations.
Industrial Oxygen Supply
50L oxygen cylinders can be used as part of industrial gas supply systems where compressed oxygen is required in portable or distributed form.
Welding and Metal Cutting
Oxygen is widely used with compatible fuel gases in metal cutting and related fabrication processes. The cylinder, valve, regulator, and connected equipment must be suitable for the intended oxygen service.
Laboratory Applications
Oxygen cylinders can be used as compressed gas sources in laboratories and technical facilities when the cylinder specification and oxygen purity are appropriate for the application.
Industrial Gas Distribution
Gas distributors can use oxygen cylinders as part of cylinder-based supply systems for industrial customers and other approved oxygen applications.
Oxygen Cylinder Safety and Handling
Oxygen is a strong oxidizing gas, and compressed oxygen cylinders require appropriate handling, storage, filling, transportation, and connection procedures. Keep oxygen cylinders away from oil, grease, flames, heat sources, and incompatible materials.
- Use only equipment and regulators approved for oxygen service.
- Keep valve outlets and connections clean and free from oil or grease.
- Secure cylinders upright during storage and transportation where required.
- Protect the cylinder valve from impact and mechanical damage.
- Do not exceed the specified working pressure.
- Inspect cylinders according to the applicable inspection and retest requirements.
- Follow the applicable local regulations for compressed oxygen storage, filling, transportation, and use.
Always follow the cylinder manufacturer’s instructions, applicable gas-supplier procedures, and local pressure-vessel regulations.
Available Oxygen Cylinder Configurations
Oxygen cylinders can be specified according to the requirements of the intended gas distribution system and destination market. Depending on the project, DSW can discuss different cylinder capacities, pressure ratings, valve configurations, markings, colours, packaging, and applicable certification requirements.
- Different water capacities
- Different working pressure requirements
- CGA and other applicable valve configurations
- Different cylinder markings and identification requirements
- Export packaging and pallet options
- Applicable inspection and certification documentation
For bulk orders, distributors and industrial gas companies can provide their required cylinder specifications so that DSW can confirm the suitable configuration before quotation and production.
