The most important standard is ABNT NBR 12791-1, which specifies the technical requirements and inspection methods for high-pressure gas cylinders.

2. Design and manufacturing requirements: Seamless gas cylinders must comply with the design and manufacturing requirements in the ABNT standard in the Brazilian market. These requirements cover the material, structure, strength, sealing performance and safety factor of gas cylinders.

3. Labeling and certification: Seamless gas cylinders sold in the Brazilian market need to undergo compliance certification and be marked with relevant certification marks. For example, Petrobras’ certification is one of the important certifications in the seamless gas cylinder market.

4. Inspection and revalidation: Seamless gas cylinders must be regularly inspected and revalidated in the Brazilian market to ensure their safety and reliability. These inspections are usually conducted by authorized inspection agencies and check the compliance of the cylinder's appearance, materials, wall thickness, valves, etc.

5. Usage restrictions: Brazil may have some restrictions on the use of seamless cylinders. For example, the maximum allowable pressure, capacity limits, or usage environment requirements for a specific gas may be specified. These limits can vary depending on the gas type and application area.
