Flanges installed on steam piping must be stamped with the manufacturer's name to ensure traceability and quality assurance. This identification is crucial for maintenance and regulatory compliance, as it allows personnel to trace the flange back to its origin, verifying that it meets the necessary manufacturing standards and specifications for safety and performance. Proper identification can help in assessing the flange's compatibility with particular steam systems and in determining whether it meets the required codes or standards for safe operation. While considerations such as the manufacturer's model number, ANSI standard number, and pressure rating are also important for understanding the flange's specifications, the primary requirement for stamping focuses on the manufacturer's name. This ensures accountability, as knowing who made the equipment plays a significant role in upholding safety standards and performing necessary inspections or replacements as needed.
