Acetylene Gas 250 cu/ft (Cylinder Size, Large, XM)

High-Performance Dissolved Acetylene Fuel Gas

Product Overview

Our Industrial Acetylene is the ultimate fuel gas for applications requiring maximum flame temperatures and intense localized heat. When combined with industrial oxygen, acetylene delivers the hottest, most concentrated flame profile of any commercial fuel gas. This rapid heat transfer enables you to pierce, slice, shape, and weld metals with unmatched speed and efficiency.

Because acetylene is chemically unstable if compressed on its own, our cylinders are uniquely engineered with a porous internal mass saturated with a liquid solvent (typically acetone). This stabilizes the gas, allowing it to be safely stored, transported, and drawn from the cylinder on demand. It remains the top choice for heavy equipment maintenance, structural steel cutting, field repairs, and custom metal work.

Key Features & Benefits

The Hottest Fuel Flame: Reaches an unrivaled oxy-fuel flame temperature of up to $3,160^\circ\text{C}$ ( $5,720^\circ\text{F}$ ), allowing for incredibly fast steel preheating times.
Highly Localized Heat Zone: Unlike cooler gases like propane, acetylene creates a tight, highly focused primary flame cone, minimizing the Heat-Affected Zone (HAZ) and reducing metal distortion.
True Fusion Welding Capability: Acetylene is the only standard fuel gas that can produce a truly neutral flame capable of fusion-welding mild steel without contaminating or embrittling the weld pool.
Lower Overall Oxygen Consumption: Requires a much lower oxygen-to-fuel ratio for combustion compared to propane or propylene, optimizing your total gas usage and operating costs.

Primary Industrial Applications

Typical Cylinder Pressure: ~250 psi at $21^\circ\text{C}$ ( $17.2\text{ bar}$ ) when fully charged

⚠️ Critical Safety & Handling Information

The 15-psi Limit: NEVER regulate or draw free acetylene gas at pressures exceeding 15 psig. Above this pressure, acetylene gas becomes highly unstable and can spontaneously decompose violently.

Keep Cylinders Upright: Always store, transport, and use acetylene cylinders in an upright position. If a cylinder is laid horizontally, liquid acetone solvent can escape through the valve, ruining your regulators and fouling your torch equipment. If a tank has been horizontal, let it stand upright for at least 2 to 4 hours before use.

Flashback Arrestors Required: Because of acetylene's high flame velocity, high-quality flashback arrestors must be installed at both the regulator and torch ends to prevent a flame from traveling backward into the hoses or cylinder.
