Question 117Steam Plants - 1st Asst/Chief

The correct answer is D) a hydrostatic test of 1.5 times the maximum allowable pressure but not less than 500 psi. This is the requirement specified in the Coast Guard regulations for new fuel oil service piping between pumps and burners. The regulations mandate that this piping must undergo a hydrostatic pressure test at 1.5 times the maximum allowable working pressure, but the test pressure must be at least 500 psi. This ensures the integrity and safety of the fuel oil system. The other options are incorrect because they do not accurately reflect the Coast Guard's specific requirements for this type of piping test. Option B is incorrect as it does not specify the minimum test pressure, and option C is incorrect as it requires a lower test pressure of 1.25 times the maximum allowable pressure.
