Question 276General Subjects - QMED
70% to passWhich of the listed types of steam end piston rod packing should be used in a steam reciprocating pump?
AReinforced rubber packing
BWire impregnated high temperature packing
CHigh-pressure graphite packing
DLow-pressure braided asbestos packing
AI Explanation
The correct answer is C) High-pressure graphite packing. High-pressure graphite packing is the appropriate choice for a steam reciprocating pump, as it is designed to withstand the high temperatures and pressures associated with steam systems. Graphite packing provides excellent sealing properties and can effectively prevent steam leaks in the piston rod area of the pump. The other options would not be suitable - reinforced rubber packing (A) is not rated for high-temperature steam service, wire-impregnated high-temperature packing (B) may not provide the necessary sealing under high pressures, and low-pressure braided asbestos packing (D) is not appropriate for the demands of a steam reciprocating pump.
