This is a revision of the Scheme for the Identification of Piping Systems, originally aff

21、irmed in 1928, reaffirmed in 1945, revised in 1956, revised in 1975, revised in 1981, reaffirmed in 1985 and 1993, and revised in 1996. Shortly after the turn of the century, with the resultant industrial expansion, it became ap- parent that some scheme should be devised to identify piping. In 1908,

22、 an article on “Identification of Power House Piping by Colors” was read at a meeting of The American Society of Mechanical Engineers. In 1909, an article called “Standard Colors for Power Station Piping” was read at the meeting of the Association of Edison Illuminating Companies. . In 1920, the Nat

23、ional Safety News pointed out the need for a color scheme for pipe lines, and the following year several papers were published and reports made to various committees, notably the Prime Movers Committee of the National Electric Light Association, The American Society of Mechanical Engineers, and the

24、U. S. Navy Department which actually wrote its spec- ifications. In the meantime, many large companies compiled their own scheme with no thought to stan- dardization of pipe colors, even in their own plants. When personnel were shifted, accidents could and did happen. The organization of the Section

25、al Committee on the Identification of Piping Systems, under the procedure of the American Standards Association (now called the American National Standards Institute, Inc.), took place on June 14, 1922. On August 23, 1950, the committee was reorganized to investigate the possibility of a revi- sion

26、to the standard. It was felt that a revision was necessary because of the tremendous num- ber of different materials being carried in pipes. After many meetings and much discussion, this revision of American Standard, Scheme for Identification of Piping Systems, was approved by the sectional committ

27、ee and sponsors. It was then presented to the American Standards Association (now called the American National Standards Institute, Inc.) for approval and des- ignation as an American Standard. This was granted on January 27, 1956. In the late 1960s the committee began discussions on the possibility

28、 of revising the .1956 Standard. These discussions continued for a number of years, eventually resulting in approval by the American National Standards Institute, Inc. and the secretariat. Approval by the American National Standards Institute, Inc. and designation as an American National Standard wa

29、s ob- tained on November 16, 1981. This latest edition of A13.1 was approved by the American National Standards Institute on August 13, 1996. Suggestions for improvement of this revision will be welcomed. They should be sent to The American Society of Mechanical Engineers, United Engineering Center,

36、a large number of industrial plants and organizations of various kinds. Generally speaking, the standards arrived at in individual cases may have given satisfaction to those using them but they also may have suffered from a lack of uniformity. Numerous injuries to personnel and damage to property ha

37、ve occurred because of mistakes made in turning valves on, or discon- necting pipes at the wrong time or place, particularly when outside agencies, such as munici- pal fire departments, were called in to assist. Furthermore, there has been considerable confu- sion in the minds of those who change em

38、ployment from one plant to another. In order to promote greater safety, lessen the changes of error, confusion, or inaction, espe- cially in times of emergency, a uniform system for the identification of piping contents has been established to warn personnel when the piping contents are inherently h

39、azardous. Therefore, while this Standard has been prepared to specify the identification of the contents of piping sys- tems on the basis of legends, it also suggests the use of color as a supplementary means of iden- tifying the type of hazard of the material contained in the system. ix Copyright A

41、d to establish a common sys- tem to assist in identifkation of hazardous materials con- veyed in piping systems and their hmds when released in the environment. cludes materials known as fire producers or those creat- ing an explosive atmosphere. 2.2.2 Chemically Active or Toxic. This classifi- cati

42、on includes materials which are corrosive, or are in themselves toxic or productive of poisonous gases. 1.2 This scheme concerns identification of contents of piping systems in industrial and power plants. It is also recommended for the identification of piping systems used in commercial and institu

43、tional installations, and in buildings used for public assembly. It does not apply to pipes buried in the ground nor to electrical conduits. 1.3 Existing schemes for identification shall be consid- ered acceptable if such schemes are described in writing and implemented so that the using-facility ca

44、n demon- strate that the basic concerns outlined in this Standard are being met. For example, petroleum refineries and primary chemical manufacturing plants, in which hazardous work permit systems and emergency procedure manuals are utilized, wherein effective methods for the identification of pipe

45、contents have been established, and wherein em- ployees are trained as to the operation and hazards of the piping systems, shall be considered as meeting the re- quirements of this Standard. (96) 2 DEFINITIONS AND REFERENCES 2.1 Piping Systems For the purpose of this Standard, piping systems shall i

46、nclude pipes of any kind and, in addition, fittings, valves, and pipe coverings. Supports, brackets, or other acces- sories are specifically excluded from applications of this Standard. Pipes are defined as conduits for the transport of gases, liquids, semiliquids, or fine particulate dust. 2.2 Mate

47、rials Inherently Hazardous 2.2.1 Flammable or Explosive. This classifica- tion includes materials which are easily ignited. It in- 2.2.3 At Temperatures or Pressures. This clas- sification includes materials which when released from the piping would have a potential for inflicting injury or property

48、 damage by bums, impingement, or flashing to vapor state. 2.2.4 Radioactive. This classification includes those materials which emit ionizing radiation. 2.3 Materials of Inherently Low Hazard This classification includes ail materials which are not hazardous by nature, and are near enough to ambient

49、 pressure and temperature that people working on systems carrying these materials run little risk through the release of these materials. 2.4 Fire Quenching Materials This classification includes sprinkler systems and other piped fire fighting or fire protection equipment. This in- cludes water (for fire fighting), foam, CO;?, Halon, etc. 2.5 References This Standard is supplemented by the fo
