Which markings are required on direct-fired vaporizers?

The required markings on direct-fired vaporizers include essential information that ensures safety, compliance, and functionality. These markings, as specified by the American Society of Mechanical Engineers (ASME) Code, are critical for identification and operational parameters of the vaporizer system.

The ASME Code outlines safety standards and practices for pressure vessels, which the vaporizer is classified as. Thus, including the heat input and vaporizing capacity not only helps operators understand the performance characteristics of the vaporizer but also ensures that it is operated within safe limits. This is crucial for preventing any operational failures or hazardous situations.

In contrast, while the manufacturer’s name and model number can be useful for identification, they do not provide the critical performance safety information required for safe operation. Safety certifications alone do not capture the specific operational parameters important to regulation compliance. The maximum pressure rating, while important, does not encompass the full range of information needed for safe and effective use. Therefore, the inclusion of all necessary markings according to ASME guidelines is essential for the safety and efficiency of direct-fired vaporizers.
