Application of explosion-proof electric heater design in petrochemical industry
Antifreeze system for heating pipes: to avoid freezing or condensation of the medium in the external pressure guiding pipe in winter. It is often used in the measurement of water, steam and other materials. For this type, a minimum temperature of 5°C should be maintained.
Explosion-proof electric heater design specification
As explosion-proof electrical and heating pipe equipment, the standard specifications for the use of explosion-proof electric heaters include: "Standard for Explosion-proof Electrical Equipment for Risky Environments" (GB 3836.1-2000); "Code for Design of Electrical Equipment for Blasting and Fire Risk Environments" ( GB 50058—92); "Code for Design of Petrochemical Appearance and Pipeline Heat Tracing and Insulation" (SH 3126—2001), etc.
The parameters involved in the calculation of heat loss include persistence temperature, ambient temperature, insulation type, external pipe type and length, maximum exposure temperature, influence of wind speed, etc.
Explosion-proof electric heater in petrochemical equipment. The development of explosion-proof electric heaters and skills has been continuously improved, and its advantages such as accurate and stable temperature control, energy saving, and environmental protection have been highlighted. Although the one-time investment is slightly higher than steam or hot water tracing, the explosion-proof electric heater system has the

The development of explosion-proof electric heaters and skills has been continuously improved, and its advantages such as accurate and stable temperature control, energy saving, and environmental protection have been highlighted. Although the one-time investment is slightly higher than steam or hot water tracing, the explosion-proof electric heater system has the advantages of high heat tracing accuracy, low production and maintenance costs, energy saving, environmental protection, and non-corrosion, which have been obtained in large petrochemical projects. More and more widely used, the following editor introduces the principle and design specifications of explosion-proof electric heaters in petrochemical equipment.
Introduction to explosion-proof electric heater system
The principle of explosion-proof electric heater The principle of explosion-proof electric heater is to install heating elements between the insulation layer and the object to be heated. It is announced that the electric heat will make up for the heat lost during the transportation and storage process, so as to keep the heating medium within a certain temperature range. . There are usually two types of external heat tracing in petrochemical equipment:
Heating tube technology heat tracing: The medium in the external pressure guiding tube loses a certain amount of heat because it is different from the surrounding temperature. It needs to be brought by the explosion-proof electric heater to reach the required surface temperature. It is often used for guessing of waxy, easy to condense, easy to vaporize, etc., to avoid segregation, accumulation, sudden increase in viscosity due to temperature drop, and increase in activity resistance. The heating temperature should be determined by the technical expertise based on the physical properties of the heating medium.
