API RP 631M

Annotation of standard text API RP 631M :

This procedure applies to air-cooled exchangers used for general refinery service, including both forced- and induced- draft type units. The procedures are based on testing complete air-cooled exchangers and are not intended for testing individual components such as fans, motors. gears, and so forth. Separate procedures are given for the following types of tests:
I. Test of an isolated single-bay air-cooled exchanger for determining sound-power levels and sound-pressure levels (Section 2).
2. Test procedures for conducting noise tests on a single bay of installed air-cooled exchangers (normally Olultibay installations) (Section 3). See more
