Full Description

Scope

This standard provides for the application of impedance heating systems for steel or steel alloy pipe and equipment. It provides recommendations for design, installation, maintenance, and repair of these systems in general industry applications.This standard applies to impedance heating systems intended to be installed in ordinary and hazardous locations with potentially explosive atmospheres.The hazardous locations include the following: In Canada Zone 2; Zone 22; or Class I, Division 2; Class II, Division 2; Class III, Division 2 as described in CSA C22.1; and In the U.S. Class I, Zone 2; and Zone 22; or Class I, Division 2;Class II, Division 2; Class III, Division 2 as described in the NEC.This standard, when used with other recognized codes and standards, is intended to cover impedance heating systems in its entirety, including system design, specification, installation, operation, testing, commissioning, and maintenance. This standard also addresses the following associated systems which are important to the performance of impedance heating systems:a)Thermal insulation system;b)Electric power supply system;c)Electric grounding system; andd)Control and monitoring system.

Purpose

This standard is intended to aid the user in specifying, installing, operating, testing during commissioning, and maintaining impedance heating systems that will:a) Maintain design temperature;b) Provide electrical, thermal, and mechanical durability and reliability;andc) Minimize hazards to the user and the surroundings.Design information, selection parameters, and data in this standard are not intended to provide a complete design primer for impedance heating systems. The information presented will provide guidelines for:a) Selecting the optimum impedance heating system design;b) Establishing design criteria and constraints for the heated pipeline or equipment to assure system compatibility;c) Preparing specifications to obtain quotations for impedance heating systems; andd) Developing information on installation, operation, testing, commissioning and maintenance of the impedance heating system.

Abstract

New IEEE Standard - Active.An application guide for the design, installation, testing, commissioning, and maintenance of impedance heating systems for pipelines and equipment intended for use in general industrial applications is provided in this standard. This standard provides requirements when utilizing impedance heating systems in ordinary as well as hazardous areas having explosive atmospheres.
