Pressure, Temperature. Buyer may measure the atmospheric pressure or may assume the atmospheric pressure to be 13.2
Pressure, Temperature. Processor may measure the atmospheric pressure or may assume the atmospheric pressure to be 14.7 psia. Processor may determine the gas temperature by using a recording thermometer; otherwise, the temperature will be assumed to be 60° F.
Pressure, Temperature a. The Pump casing shall operate without leakage or internal contact between rotating and stationary components. Internal clearances shall be maintained as specified in applicable standard.
b. The casing shall be designed to withstand simultaneously MAWP (Max. Allowable Working Pressure) at corresponding temperature and the worst-case combination of twice the allowable nozzle loads as per applicable standard.
c. In case of Centrifugal Pumps, radial split casings shall be used for any of the following operating conditions:-
i. Pumping temperature of 200 deg. C or higher (a lower temperature limit should be considered if thermal shock is probable).
ii. Flammable or hazardous pumped liquid with a relative density of less than 0.7 at the specified pumping temperature.
iii. Flammable or hazardous pumped liquid at a rated discharge pressure above 100 bar. For applications like pipeline products transfer, feed water etc. pumps designed as per proven vendor standards shall also be acceptable for MAWP of higher than 100 bars.
d. The maximum allowable speed rating for reciprocating pumps shall be as per applicable standard.
e. Pulsation suppression shall be provided at the discharge of all metering pumps.
Pressure, Temperature. Buyer may measure the atmospheric pressure or may assume the atmospheric pressure to be 13.2 psia. Buyer may determine gas temperature by using a recording thermometer, otherwise, the temperature will be assumed to be 60°F. The specific gravity will be determined annually, or more often at Buyer deems advisable.
