What must each pipe and tubing in a mechanical system display?

Each pipe and tubing in a mechanical system must display the identification of the manufacturer. This requirement is crucial for several reasons.

Firstly, manufacturer identification ensures traceability, allowing for effective communication regarding the product. If there are issues related to the pipe or tubing, knowing the manufacturer provides a way to obtain necessary information about the product, such as specifications, installation guidelines, and warranty details.

Additionally, proper identification can aid in compliance with relevant codes and standards. With clearly marked manufacturer information, inspection and maintenance can be performed more effectively, promoting safety and reliability in mechanical systems.

In contrast, while the year of manufacture, certification of safety, and the intended use of the pipe are all important factors in evaluating the suitability and compliance of the materials used, they are not universally mandated for display on every pipe and tubing. The primary focus is on the manufacturer's identification to facilitate these broader compliance and safety considerations.
