Electric Heat Tracing Technical Solution for Oil Refinery and Petrochemical Plant is the technical solution package to be applied on the refinery and petrochemical plant for heat trace the instrumentations and equipments. In general, electric heating designer and manufacturers suggest that users should provide detailed working conditions and requirement when selecting the type. Once the suitable heat trace is selected, designed, manufactured and installed, the whole electric heating scheme can ensure the smooth operation of the relevant refining facilities under various working conditions.
Electric heating of air separation instrument in phase I project of 40 million tons/year refining and chemical integrated project of zhejiang petrochemical co., LTD adopts self-limiting temperature electric tracing belt and MI armored heating cable.
Self-limiting temperature electric tracing belt is a new generation of strip constant temperature electric heating products, automatically limit the heating temperature, and automatically adjust the output power with the temperature of the heat tracing body; It can be arbitrarily cut or lengthened within a certain length range.Allow multiple overlapping without the risk of high temperature overheating and burning; Easy maintenance and energy saving.
MI heating cable is made of single or multiple alloy electric heating wire as heating source, high purity, high temperature, electric melting crystallization magnesium oxide as thermal insulation, seamless continuous stainless steel or copper tubes as sheath, using special production process. Used in highly corrosive places, PE or low smoke halogen-free coat should be added to the original cable. Its advantages are excellent mechanical strength and corrosion resistance.
