What fitting should you install in the rig piping to a pump to facilitate disconnecting the pump for servicing?
AI Explanation
The correct answer is D) Union.
A union is the fitting that should be installed in the rig piping to a pump to facilitate disconnecting the pump for servicing. Unions allow the piping to be easily disconnected, enabling the pump to be removed for maintenance without having to disassemble the entire piping system. This is a common practice in marine engineering to provide accessibility and serviceability for equipment.
The other options, such as a flange, coupling, or nipple, do not provide the same level of easy disconnection that a union does, making them less suitable for this application where the pump needs to be serviced regularly.
