Which of the following represents a container designed according to the ASME code?

A pressure vessel is specifically designed and constructed according to the ASME (American Society of Mechanical Engineers) code. This code sets the standards for the design, fabrication, inspection, and testing of pressure vessels, ensuring safety and reliability while handling high-pressure gases or liquids.

The ASME code outlines the materials and design parameters necessary to withstand internal pressures, thereby ensuring that pressure vessels can operate safely under their intended conditions. By adhering to these standards, manufacturers can ensure that their pressure vessels are capable of meeting regulatory requirements and safeguarding operational integrity.

Other container types, such as portable tanks, storage drums, and flexible bags, do not necessarily have to follow ASME codes. While they may be designed for specific applications, they do not have the same rigorous standards required for pressure vessels that deal with high-pressure scenarios as specified by ASME regulations.
