GB/T 20322-2006

This standard specifies the minimum requirements for reciprocating compressors (hereinafter referred to as compressors) with oil lubrication or oil-free lubrication used in the oil and gas industry, as well as their driving engines. This standard applies to compressors used in critical facilities at medium and low speeds, and related lubrication systems, controls, instruments, intermediate coolers, aftercoolers, pulsation suppression devices, and other auxiliary equipment. This standard may also be used in other facilities or other industries upon consultation. This standard does not apply to compressors driven by integrated gas engines, assembled high-speed separable engines, single-acting cylindrical (automobile type) pistons used as crossheads, and mechanical equipment or instrument air compressors with an exhaust pressure of 0.9 MPa or less. This standard also does not apply to gas engines and turbine driving engines.
