Acetylene Cylinders & Bottles
Reliable High-Pressure Gas Storage Solutions
DSW offers a wide range of high-quality acetylene cylinders, bottles, and tanks, designed for safe and efficient storage and transportation of acetylene gas.
Our products serve various industrial applications, including welding, cutting, automotive repair, and chemical production.
What Are Acetylene Cylinders?
Acetylene cylinders are specially designed high-pressure vessels that store acetylene gas dissolved in acetone, absorbed by a porous calcium silicate mass inside the cylinder. This design prevents gas decomposition, reducing the risk of hazardous reactions. For safety, acetylene cylinders must always be stored upright to avoid leaks or dangerous pressure changes.
Key Features
- Durable Construction: Manufactured from seamless, high-strength steel for maximum safety and long service life.
- Safety Design: The porous calcium silicate filling stabilizes acetylene gas to prevent decomposition and volatility.
- Wide Size Range: From small portable cylinders (2L, 7.5L) to large industrial tanks (up to 60L and beyond).
- Standard Compliance: Certified to meet ISO 3807:2013, DOT, TC, TUV, and other international safety standards.
- Reliable Valves: Equipped with QF-15A14 valves or custom options to fit various applications and regulations.
- Corrosion Resistance: Finished with phosphate coating and powder paint or epoxy resin for durability in harsh environments.
