ASME B19.3 pdf download SAFETY STANDARD FOR COMPRESSORS FOR PROCESS INDUSTRIES
1.2 Scope
(a) The specific recommendations in this Standard cover the requirements for safety devices and protective facilities to prevent compressor accidents as a result of excessive pressure, destructive mechanical failures, inter- nai fires or explosions, and leakage of toxic or flammable fluids. General safety practices and hazards unique to compressors are also covered. This Standard applies to the compressor and its auxiliaries, including drivers, in- tercoolers, surge chambers, disengaging drums or scrubbers, interconnecting piping and lubrication, seal oil, and jacket water systems. The requirements of this Standard apply to all types of compressors (centrifugai, axial, rotary, and reciprocating) which are an integral part of facilities for processing petroleum, petrochemicals, or chemicals, including air separation plants. This Standard does not apply to plant utility air compressors.
(b) Although the provisions of this Standard will apply to the majority of typical compressors used in the process industries, exceptions to these recommendations with regard to certain facilities of unusual design or complexity may be necessary. In such cases, it is intended that design- ers capable of applying a complete and rigorous analysis to system requirements shall have latitude in the development of safety features. Provisions in this Standard arenot intended to apply to (l) and (2) below:
(1) basic mechanical design of compressor components. This Standard is based on the requirement that thecompressor components be designed by qualified engineers in accordance with the recognized standards andspecifications. Further, it is essential that these engineershave a thorough knowledge of the basic concepts of thedesign of such equipment components as cylinders, pistons,crankshafts.flywheels, bearings, pressure vesselsand piping.
(2) design and operation of connected process facil
ities.
(c) The principles promoting safe operation of compressors used for process industries are not restrictedto new compressor systems. it is recommended that allcompressor systems be reviewed to consider possiblechanges due to revision of this Standard.
