Industrial High-Pressure Acetylene Gas Cylinder
Engineered for safe dissolved acetylene storage, strict compliance, and high-frequency industrial filling operations.
Technical Specifications & Parameters
Selecting the correct acetylene cylinder requires precise alignment with gas distribution standards and filling station infrastructure. Unlike permanent gas cylinders, acetylene cylinders contain a porous mass and a solvent.

Product Selection Guide: Construction & Internal Technology
Acetylene cannot be safely compressed as a free gas above 1.5 bar without risk of explosive decomposition. Our cylinders manage this physical property through controlled internal architecture.
Porous Mass Structure: Filled with monolithic calcium silicate or asbestos-free porous mass maintaining a controlled porosity of 88% to 92%, ensuring uniform gas dispersion and flame arresting capability.
Solvent Management: Optimized acetone saturation ratios per ISO 3807, preventing solvent loss during high-draw gas withdrawal.
Shell Material: Fabricated from high-grade alloy steel plates (e.g., HP345 or equivalent normalized pressure vessel steel), offering high impact resistance and uniform microstructures.
Valve Integration: Equipped with brass valves featuring integrated fusible plugs designed to melt at 100°C–104°C to safely relieve pressure in external fire scenarios.
Application Suitability
Built for heavy industrial deployment, supply chain stability, and continuous gas distribution cycles:
Industrial Gas Filling Stations: Batch filling of acetylene for regional distribution networks.
Heavy Metal Fabrication: Fuel supply for structural steel cutting, gouging, and localized pre-heating.
Shipbuilding and Offshore Maintenance: Portable gas manifolds used in restricted shipyard environments.
Chemical Processing: Controlled fuel delivery for specialized synthesis applications.
Manufacturing Process & Quality Verification
Every cylinder undergoes a strict production sequence traceable via permanent stamping on the shoulder.
Blanking & Deep Drawing: High-precision hydraulic presses form seamless steel billets into uniform cylindrical shells.
Heat Treatment: Full-body normalization relieves internal stresses introduced during cold forming, stabilizing mechanical properties.
Porous Mass Curing: Automated batch autoclaves cure the internal calcium silicate matrix, followed by controlled moisture extraction ovens.
Hydrostatic & Leak Testing: 100% water jacket testing at 60 bar test pressure, combined with pneumatic leak detection around valve threads.
Surface Treatment: Shot-blasting to Sa 2.5 cleanliness standard, followed by electrostatic powder coating and thermal curing for corrosion resistance.
Compliance & Certifications
Manufacturing Standards: ISO 3807 (Acetylene cylinders - Basic requirements and type testing), ISO 11439 / GB 11638.
Regulatory Approvals: DOT-8 / DOT-8AL compliant options available for North American markets; TPED (PI_Mark) certified for European distribution.
Inspection Reports: Material Test Certificates (EN 10204 3.1) and third-party inspection reports (TÜV, SGS, or Bureau Veritas) supplied with every shipment.
Frequently Asked Questions
Q: What is the maximum safe withdrawal rate for acetylene from these cylinders?
A: Standard operational safety guidelines dictate that the gas withdrawal rate should not exceed 1/10th of the cylinder's total capacity per hour to prevent acetone carryover into regulators and hoses.
Q: Can these cylinders be supplied empty or pre-filled?
A: All cylinders are shipped dry and empty (or charged with nitrogen holding pressure upon request) to comply with international hazardous material transport regulations. Acetone and acetylene must be filled locally by certified distributors.
Q: What is the re-test interval for periodic inspection?
A: Depending on local jurisdiction (e.g., DOT or TPED regulations), periodic visual inspection and hydrostatic re-testing are typically mandated every 5 to 10 years.
Q: What custom OEM options are available for bulk orders?
A: We support custom paint colors, embossed or stenciled client logos on the shoulder, specific valve thread configurations (CGA, DIN, BS, JIS), and stamped tare weight verifications.
