Foreword

(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 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 industry 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 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 power, control, and alarm systems, other standards, some of which are listed in Clause 2, should be referred to when using this recommended practice. The recommendations here are not intended to supersede any current standards or recommended practices, and sound engineering judgment should always be used when applying this or any other standard.

This recommended practice correlates petrochemical industry practices; it is not intended to be a design guide or an exhaustive procedure manual. It may be used to evaluate different heating systems and suppliers of those systems for suitability and performance. The appendixes are included for information only; they are not part of this recommended practice.
