P844.5 - Recommended Practice for the Design, Installation, Testing, Commissioning and Maintenance of Induction Heating Systems for Pipelines, Vessels, Equipment, Structures and Induction Susceptor Heating Furnaces
This recommended practice provides for the design, installation, testing, operation, commissioning and maintenance of induction heating systems for pipelines, vessels, equipment, structures and induction susceptor heating furnaces. This recommended practice applies to general industry induction heating applications in ordinary locations as well as in hazardous areas having explosive atmospheres. This recommended practice, when used with other recognized codes and standards, is intended to cover induction heating systems including, system design, specification, installation, operation, testing, commissioning and maintenance. This recommended practice also addresses the following associated systems which are important to the performance of induction heating systems: A) Heating system B) Piping system C) Thermal insulation system D) Electric power supply system E) Electric grounding system F) Control and monitoring system
P844.3 - IEEE Draft Standard for Impedance Heating of Pipelines and Equipment - General, Testing, Marking, and Documentation Requirements
This standard applies to general, testing, marking, and documentation requirements for impedance heating systems for steel or steel alloy pipe or equipment, rated up to and including 132 Vac. These heating system components are intended for installation in accordance with the CSA C22.1, Canadian Electrical Code, Part I (CE Code); NFPA 70, National Electrical Code(R) (NEC(R)) in the U.S.; or with any other national electrical installation code, as applicable. This standard applies to impedance heating systems intended to be installed in ordinary and hazardous locations. The hazardous location installations are limited to 30 Vac and 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; Zone 22; or Class I, Division 2; Class II, Division 2; Class III, Division 2 as described in the NEC. This standard also applies to power connection points and control methods used with impedance heating systems. NOTE 1-- Requirements for certification of insulated impedance conductors with insulation temperature ratings above 105?C may be considered under a special investigation by an accredited certification body. NOTE 2-- Information on transformer, power distribution and control components can be found in IEEE Std 844.4/CSA 293.4.
P844.4 - IEEE Draft Standard for Impedance Heating of Pipelines and Equipment - Application Guide for Design, Installation, Testing, Commissioning and Maintenance
This standard provides 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. This standard provides requirements when utilizing impedance heating systems in ordinary as well as hazardous areas having explosive atmospheres.
844-2000 - IEEE Recommended Practice for Electrical Impedance, Induction, and Skin Effect Heating of Pipelines and Vessels
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 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 particular to each. These rec- ommended practices are intended to apply to the use of these heating systems in general industry.
844.1/CSA C22.2 No.293.1-2017 - IEEE/CSA Standard for Skin Effect Trace Heating of Pipelines, Vessels, Equipment, and Structures - General, Testing, Marking, and Documentation Requirements
General requirements, testing, markings, and documentation for skin effect trace heating systems for pipelines, vessels, equipment, and structures intended for use in general industrial applications are provided in this standard. This standard provides requirements when utilizing skin effect trace heating systems in ordinary as well as hazardous areas that have potentially explosive atmospheres.
