Acetylene Gas Cylinder
Industrial Acetylene Gas Cylinders | Monolithic Calcium Silicate Porous Mass & DOT-8AL / ISO 3807 / TPED Compliant
Product Overview & Technical Specifications
Engineered for safe containment and stable delivery of dissolved acetylene. Unlike standard compressed gas cylinders, these pressure vessels are packed with a high-efficiency monolithic calcium silicate porous mass (asbestos-free, reinforced with glass fiber) and pre-dosed with precision-measured acetone to suppress gas dissociation. Formed from high-grade seamless steel billets to withstand continuous industrial charging cycles.

Product Selection & Operational Limits
Correct cylinder selection requires calculating gas consumption rates and matching regional regulatory compliance codes.
Withdrawal Rate Threshold
Continuous gas extraction must not exceed 1/10 of the total cylinder capacity per hour to prevent acetone carryover into regulators and torches. Manifold systems are required for high-flow fabrication lines.
Solvent Equilibrium
Acetone levels are factory-calibrated relative to the porous mass volume. Recertification facilities must log solvent weight additions during periodic maintenance.
Safety Relief Assemblies
Fitted with brass valve bodies incorporating bottom fusible plugs (melting range 100°C to 104°C) to vent gas safely during external fire exposure.
Industrial Application Suitability
Built for heavy fabrication environments requiring high-temperature fuel gas performance:
Metal Fabrication & Shipyards
Structural steel plate cutting, scarfing, and heavy preheating via oxy-acetylene torches.
HVAC Manufacturing & Repair
High-output copper-to-brass brazing and localized thermal straightening.
Regional Gas Bottling Plants
Supplied vacuum-conditioned with inert gas preservation, ready for direct acetylene charging and local distribution.
Manufacturing & Quality Control Workflow
Strict metallurgical controls and automated processing eliminate structural defects and porous mass settling:
Billet Testing
Ultrasonic inspection of seamless steel stock for internal laminations and inclusions.


Deep Drawing & Hot Spinning
Mechanical shell forming to maintain uniform wall thickness profiles.
Thermal Normalization
Full-body heat treatment to eliminate internal mechanical stresses and optimize tensile boundaries.


Porous Mass Infusion & Autoclave Curing
Automated injection of calcium silicate slurry followed by controlled steam curing to achieve uniform micro-porosity (88% to 92% void volume).
Vacuum Dehydration & Acetone Charging
Multi-stage thermal drying followed by precise weight-monitored acetone saturation.


Pressure Proof Testing
Hydrostatic expansion and proof-pressure testing conducted at designated test pressures alongside pneumatic leak tests.
Compliance, Certifications & Traceability
Global deployment requires explicit regulatory documentation and independent validation:
Governing Standards
Manufactured to DOT-8AL / TC-8WAM (North America) and ISO 3807 / EN 1800 with TPED (Transportable Pressure Equipment Directive) compliance for the European market.
Independent Third-Party Inspection
Batch witness testing and physical verification available via TÜV, SGS, or Bureau Veritas (Pi-marked for European distribution where applicable).
Permanent Stamping
Heat numbers, serial numbers, tare weight (including valve, porous mass, and baseline solvent), and manufacturing dates are cold-stamped on the shoulder, matching the Mill Test Certificate (MTC).
Supplier Evaluation & Manufacturing Capacity
Assessing factory readiness for long-term supply agreements:
Production Volume
Automated lines yielding up to 60,000 cylinders annually across standard industrial sizes.
OEM/ODM Customization
Custom powder-coat paint matching RAL palettes, customer trademark rolling on shoulders, and tailored threading configurations (NPT, BSP, CGA, W21.8).
Logistics & Export Packaging
Secured in heavy wooden export pallets or shrink-wrapped container cradles complete with dangerous goods (DG) packing declarations for Class 2.1 transport.
