Robust Construction & Safety Features

These cylinders are manufactured using high-quality seamless steel and fitted with a brass valve for dependable operation. The inclusion of a porous mass, either calcium silicate or charcoal/asbestos, ensures the safe storage of acetylene by minimizing risk and enhancing gas stability. Fusible plugs and strict adherence to safety standards further amplify cylinder protection.

Performance & Compliance

Acetylene cylinders meet rigorous standards including IS:7312, DOT-8, and EN ISO 3807, reinforcing their suitability for industrial usage. With a maroon color coding and a neck thread of 3/4" BSP, these cylinders operate efficiently within a temperature range of -20C to +55C. Testing pressure stands at 35 kg/cm while working pressure ranges between 15-18 kg/cm, supporting high performance in demanding environments.

Wide Range of Applications

Designed for welding, metal cutting, and other industrial tasks, these cylinders deliver consistent performance with a gas purity of 98%. Their durable build and ample capacity (40 to 47 litres) make them ideal for frequent usage in diverse sectors. The recommended upright storage in ventilated areas facilitates longevity and ensures operational safety for users.

FAQs of Acetylene Gas Cylinders:

Q: How should Acetylene Gas Cylinders be stored to ensure safety?

A: Acetylene gas cylinders must be stored upright in a well-ventilated area as per safety guidelines. This positioning helps prevent the accumulation of liquid acetylene in the valve and reduces fire hazards, ensuring safe and secure storage.

Q: What are the key benefits of using cylinders with a brass valve complying with IS:3224?

A: Brass valves per IS:3224 offer robust corrosion resistance and are specifically designed for gas applications. Their reliable sealing mechanisms enhance operational safety and minimize the risk of leaks, making them ideal for industrial use.

Q: When is it necessary to check the cylinders pressure and what is the safe working range?

A: Cylinder pressure should be checked before every use to confirm safety. The working pressure for these acetylene cylinders is 15-18 kg/cm, with a maximum allowable limit of 21 kg/cm, ensuring safe operation within recommended thresholds.

Q: Where can Acetylene Gas Cylinders be used effectively?

A: These cylinders are suitable for locations that require welding, metal cutting, or other industrial operations. Their robust construction, safety features, and compliance with international standards make them widely applicable across manufacturing, fabrication, and maintenance industries.

Q: What is the process for inspecting or maintaining an acetylene cylinder?

A: Regular inspections involve checking for external damage, verifying the integrity of the valve and fusible plug, and ensuring the cylinder is stored correctly. Testing pressure should be periodically measured, with professional maintenance conducted as per the manufacturers guidelines to ensure continued safety and efficiency.

Q: How does the porous mass benefit acetylene storage in these cylinders?

A: The porous mass, made from calcium silicate or charcoal/asbestos, distributes acetylene safely within the cylinder and minimizes the risk of decomposition or explosion. It stabilizes the gas, enhancing the cylinders safety during transportation and use.
