What is the proper hourly withdrawal rate for acetylene gas from a cylinder?

The proper hourly withdrawal rate for acetylene gas from a cylinder is accurately represented by limiting it to no more than one-seventh of the cylinder capacity. This recommendation is essential for safety and efficiency in oxyfuel cutting operations. Acetylene is a highly volatile gas, and if withdrawn too quickly, it can create pressure drops that lead to unstable combustion and potential hazards such as flashbacks or equipment failure.

Typically, acetylene cylinders are designed to contain acetylene dissolved in a solvent, which allows for safe storage under pressure. To maintain the integrity of the cylinder and ensure consistent delivery of gas, it’s crucial to adhere to the recommended withdrawal rates. Exceeding this limit can not only compromise safety but may also reduce the quality of the flame produced during cutting, impacting the overall effectiveness of the oxyfuel cutting process.

Understanding this rate helps operators manage their usage and maintain safe practices, which are paramount in any welding or cutting application.
