Rajesh,
Surely the operating load is the normal load and the earthquake the unusaul case. WLogic tells us that when the earthquake occurs the pipe is likely to be subject to the high temperature case. Thus both should be considered.
Its different for wind, traffic, snow and earthquake as all are unsustained loads.

Dear Tanmoy,
Seismic loads are to be combined with operating tempearture Load for stress
analysis.
As there is very rare possibility for occurence of both the condition
(Design & seismic)at once.
& for seismic case Normal Allowable loads do not apply.
refer design spec. of the project or consult to mechanical dept.
Regards,
rajesh.
