Is it permissible to engrave the shell of a mild steel cylinder?

• A. Yes
• B. No
• C. Only if specified by law
• D. Only for cylinders over 20 years old

Answer: (A)

Engraving the shell of a mild steel cylinder is permissible because it does not compromise the structural integrity of the cylinder, provided that it is done carefully and without causing damage to the pressure vessel. This practice is often used for identification purposes, such as marking ownership or maintenance history. Ensuring that the engraving does not affect the cylinder's ability to safely retain pressure is crucial. In contrast, options suggesting limitations based on law or the age of the cylinder impose unnecessary restrictions that are not standard practice. There's no specific law that generally prohibits such engraving, nor does the age of the cylinder inherently change the rules regarding marking it. The focus should be on the technique used and adherence to safety protocols rather than arbitrary constraints.
