API STANDARD 618 FOURTH EDITION, JUNE 1995
This standard covers the minimum requirements for reciprocating compressors and their drivers used in petroleum, chemical, and gas industry services for handling process air or gas with either lubricated or nonlubricated cylinders. Compressors covered by this standard are of mod- erate-to-low speed and in critical services. Also covered are related lubricating systems, controls, instrumentation, inter- coolers, aftercoolers, pulsation suppression devices, and other auxiliary equipment. Compressors not covered are (a) integral gas-engine-driven compressors with single-acting trunk-type (automotive-type) pistons that also serve as crossheads and (b) either plant or instrument-air compressors that discharge at a gauge pressure of 9 bar (125 pounds per square inch) or less. Also not covered are gas engine and steam engine drivers.
