AI Explanation
The correct answer is D) 250 psi and 460°F. The Coast Guard regulations permit the use of copper pipe for steam service subjected to a maximum pressure of 250 psi and a maximum temperature of 460°F. This is specified in the applicable regulations for the construction and installation of piping systems on commercial vessels. The other options are incorrect because they do not match the pressure and temperature limits allowed by the Coast Guard regulations. Option B (350 psi and 460°F) and Option C (350 psi and 406°F) exceed the maximum pressure limit of 250 psi.
