Heat Tube Induction Heating Systems Stabilized Design

Abstract

Heat tube induction heating systems are increasingly used at oil and gas production and petrochemical facilities. The existing requirements for explosion-proof electric trace heaters are not subject to induction systems; in particular, the sheath maximum temperature calculation methods are not applicable. In this paper there has been suggested a set of worse operating conditions and a calculation method to predict the heater maximum temperature that can be used when creating a stabilized design of heat tube induction heating systems.
