Is a separate license required for cylinder design?

1. Are gas cylinders designed by manufacturers authorized to produce B1, B2, and special-type gas cylinders? Or can anything be designed, and after that taken to the manufacturing factory for design approval? Are the designs usually done by the manufacturers?
Cylinder design requires going through the corresponding approval procedures. Generally, the design of gas cylinders is carried out by manufacturing units with the appropriate qualifications, including those holding B1, B2, or special gas cylinder manufacturing licenses. These manufacturing units carry out the design of gas cylinders in accordance with relevant standards and regulations, and complete the design evaluation. Generally, the design and manufacturing of gas cylinders are carried out by the same entity or company. Manufacturing plants usually possess design capabilities and can carry out the design of gas cylinders according to the required specifications and demands. But there may be other scenarios as well; the design and manufacturing might be carried out by different units or different companies, but after the design is completed, an evaluation is necessary to ensure compliance with relevant standards and regulations. In either case, the design of gas cylinders requires corresponding approval. .
