Total Rod Load (Reciprocating Compressor)

The maximum allowable load in tension plus compression that can be applied, used by some manufacturers without an API definition. Note: The total rod load limit is typically less than the sum of the internal gas load limit in compression and in tension. Some manufacturers also list a rod load limit, which is defined as an internal gas load. A combined rod load limit is not published; however, combined rod load is calculated on the performance sheet and used in determining acceptable rod load reversals at the crosshead pin.
