A major steel tank manufacturer needed a permanent marking solution that complied with strict steel tank industry regulations.
Advantages of Indenting with Metal Stamping Machines
One of the standout features of Numberall’s roll marking machines is the use of indenting with metal stamping. This technique creates an indentation on the cylinder’s surface, providing several advantages:
- Durability: Indented markings are permanent and withstand harsh conditions, ensuring legibility throughout the cylinder’s lifecycle.
- Precision: Metal stamping machines deliver high accuracy, guaranteeing consistent and precise markings.
- Cost-Effectiveness: The automated nature of these machines enhances efficiency and reduces costs, especially for large-scale production.
- Heat Resistance: Indenting does not expose the metal to heat, preventing any heat-related changes to the cylinder.
Integration with Modern Manufacturing Processes
Numberall’s marking equipment is designed for easy integration with modern manufacturing processes. Their systems can be seamlessly incorporated into production lines, ensuring minimal disruption and maximum efficiency. This integration capability is essential for maintaining high production speeds and ensuring that all parts are marked accurately and consistently.

Industry Standards for Steel Tank & Gas Cylinders: How Numberall Delivers Excellence
In the manufacturing of gas cylinders, adherence to stringent regulations is crucial for ensuring safety and traceability. The Department of Transportation (DOT) has established comprehensive guidelines for marking and identifying gas cylinders, which manufacturers must follow to maintain compliance and safety
Essential Identification Marks
Markings on gas cylinders are essential for tracking and ensuring safety. These marks provide vital information about a cylinder’s origin, ownership, and maintenance history. The key identification marks include:
- DOT or ICC Identification Number: This number signifies the cylinder’s compliance with DOT regulations. For example, “DOT3BB3500” denotes a specific type of cylinder.
- Serial Number: Each cylinder is assigned a unique number for identification.
- Owner Information: Markings include the names of both the original and current owners, usually located on the neck ring.
- Maintenance Dates: Dates for the original hydrostatic test and any subsequent maintenance or requalification tests must be included.
