Question 363Steam Plants - Assistant Engineer

The correct answer is C) no stress is transmitted to the valve. When installing new safety valve escape piping, it is crucial to ensure that no stress is transmitted to the valve. This is because the safety valve is a critical component that must be able to operate freely and without any impediment in order to effectively relieve excess pressure and prevent potential hazards. Transmitting stress to the valve could compromise its functionality and integrity, which would undermine the overall safety of the system. The other answer choices are not correct because: A) routing the piping directly to the bilge may not be the optimal or required configuration; B) while the quick-closing valve should operate freely, this is not the primary precaution to consider when installing the piping; and D) the presence of bends or elbows in the line, while potentially important, is not the key factor in ensuring the safety of the valve.
