4、2001 American National Standards Institute Abstract: Recommended practices are provided for the design, installation, testing, operation, and maintenance of impedance, induction, and skin-effect heating systems. Thermal insulation and control and monitoring are addressed. General considerations for
5、heating systems are discussed, covering selection criteria, design guidelines and considerations, power systems, receiving and storage, installation, testing, operations, and maintenance. These aspects are then discussed for each of the above types of systems, along with special considerations parti
6、cular to each. These recommended practices are intended to apply to the use of these heating systems in general industry.

8、ating Com- mittees of the IEEE Standards Association (IEEE-SA) Standards Board. Members of the committees serve voluntarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject wit
9、hin the Institute as well as those activities outside of IEEE that have expressed an interest in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, pur
10、chase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the sta
11、ndard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is rea- sonable to conclude that its contents, although still of some value, do not wholly reflect the present state
12、of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a
13、 proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will
14、 initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standard
15、s Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE-SA Standards Board 445

All rights reserved.iii Introduction (This introduction is not a part of IEEE 844-2000, IEEE Recommended Practice for Electrical Impedance, Induction, and Skin Effect Heating of Pipelines and Vessels.) The types of heating
22、systems covered by this draft recommended practice have been used for a number of years in the petrochemical industry. They were recognized for the first time in the 1981 issue of the National Electrical Code? ANSI/NFPA 70-1990. Electrical heating of pipelines and vessels in the petrochemical indust
23、ry is a growing portion of total heating requirements because of its advantages in temperature control and the rise of energy costs. This recommended practice is a companion document and supplements IEEE Std 515-1997, IEEE Standard for the Testing, Design, Installation, and Maintenance of Electrical
24、 Resistance Heat Tracing for Industrial Applications. While this recommended practice may be used with IEEE Std 515-1997 to select the type of electrical heating to be used, it is a stand-alone document for the types of heating it covers. Since electric heating systems are interrelated with electric
