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, (6) Although the provisions of this Standard will apply to the majority of typical compressors used in the process industries, exceptions to these recommendations with re- gard to certain facilities of unusual design or complexity may be necessary. In such cases, it is intended that designers capable of applying a complete and rigorous analysis (a) b) to system requirements shall have latitude in the development of safety features. Provisions in this Standard are not intended to apply to (i) and (2) below:
( I ) basic mechanical design of compressor compo- nents. This Standard is based on the requirement that the compressor components be designed by qualified engi- neers in accordance with the recognized standards and specifications. Further, it is essential that these engineers have a thorough knowledge of the basic concepts of the design of such equipment components as cylinders, pis- tons, crankshafts, flywheels, bearings, pressure vessels, and piping.
(2) design and operation of connected process facil- ities.
(c) The principles promoting safe operation of com- pressors used for process industries are not restricted to new compressor systems. It is recommended that all compressor systems be reviewed to consider possible changes due to revision of this Standard.
1.3 Definitions maximum allowable temperature – the maximum tem- perature for which the manufacturer has designed the compressor (or any part to which the term is referred) when handling the specified gas at the specified pressure maximum allowable working pressure -the maximum pressure for which the manufacturer has designed the compressor (or any part to which the term is referred, such as an individual cylinder or casing) when handling the specified gas at the specified temperature maximum continuous speed – the highest speed at which the manufacturer’s design will permit continuous opera- tion with overspeed and governor mechanisms installed and operating
