Portable Explosion-Proof Flanged Electric Heating Tube Dimensions and Features - Yangzhou Darui
Darui Electric recommends for you
1. It consists of a heating core and a protective tube. The heating core uses a tubular electric heating element as the heat source, and the protective tube is made of thin stainless steel. It has a large heat dissipation area and fast heat transfer. The terminal part is divided into ordinary type (using an iron drawn cup-shaped shell) and special type (using a bolted explosion-proof device shell seal). The special type meets the requirements of explosion-proof mark dIICT4 and protection level IP65 series standards.
2. It is connected to the oil tank container body by flanges. The protective tube isolates the heating core from the heated oil. When repairing the electric heater, there is no need to drain the oil in the tank; simply pull out the heating core and replace it with a new one, making maintenance convenient.
3. During design, the contact area between the protective tube and the heated oil should be considered to prevent local carbonization of the oil due to excessive heating temperature. This type of heater is only suitable for heating heat transfer oil or oils and media with good heat transfer effects.

Product introduction:
It is widely used in China's petrochemical, metallurgical and other industries. However, its service life is not as long as other new types of heaters. Its heating power per unit area is relatively high, making it easy to produce carbon deposits on the heater surface.
This heater is an explosion-proof type, widely used in China's petrochemical, metallurgical and other industries. However, its service life is not as long as other new types of heaters. Its heating power per unit area is relatively high, making it easy to produce carbon deposits on the heater surface. Especially for heaters above 5KW, the normal service life is only about 3 years. Therefore, this heater is not our company's product.
Product parameters:
It is composed of an explosion-proof heating tube and an explosion-proof junction box. The stainless steel heating tube evenly distributes high-temperature resistance wires inside a high-temperature resistant stainless steel seamless tube, and fills the gaps densely with crystalline magnesium oxide powder that has excellent thermal conductivity and insulation properties. This structure not only leads to high thermal efficiency but also uniform heating. When current passes through the high-temperature resistance wires, the heat generated by the heating tube is dispersed through the crystalline magnesium oxide powder to the metal tube surface, and then transferred to the heated object or air, achieving the purpose of heating. The reserved hole for flange connection is: ≥Φ70.
