Pressure Rated Electric Flange Immersion Heater from China Suppliers - High Efficiency Factory Solutions

Flange-type electric heaters, also recognized as plug-in electric heaters, are essential heating solutions widely used in various industrial applications across China. These heaters are particularly effective in heating storage tanks, containers, pipelines, and are well-suited for industries such as petroleum, chemicals, food, and machinery. Their versatility allows them to heat and maintain the temperature of various media, including liquids, gases, and low-melting-point metals, Manufactured by leading suppliers and factories in China, these flange-type electric heaters feature multiple U-shaped tubular electric heating elements that are densely welded to the flange. Constructed from high-quality materials like stainless steel, nickel-chromium alloy wire, and modified magnesium oxide powder, they adhere to rigorous industry technical standards. The core components are designed for durability, employing argon arc welding or modular assembly, enabling easy replacement of single electric heating tubes to minimize maintenance costs, These electric heaters offer voltage adaptability of 220V/380V and a comprehensive power range from 2KW to 10000KW, boasting thermal efficiency exceeding 90%. Equipped with a built-in PID temperature control system and interlock protection devices, they automatically power off in cases of over-temperature or low liquid levels for enhanced safety. Select models meet the stringent ExdⅡBT4 explosion-proof certification standards, ensuring safe operation in hazardous environments, Our innovative design includes a flexible mounting structure with movable wheels and vibration-damping components, enhancing both deployment safety and operational flexibility.

    Flange Heater Features

    High surface power, heating the air at 2 to 4 times the surface load.

    Highly compact and compact. Due to its short, dense design, it offers excellent stability and requires no brackets for installation.

    Combined models typically use argon arc welding to connect the heating tubes to flanges. Alternatively, a fastener assembly can be used: each heating tube is welded with a fastener. The flange cover is then secured with a nut. The tubes and fasteners are welded using argon arc welding, ensuring leak-proof sealing. Fasteners are sealed using advanced technology. Individual tube replacement is extremely convenient, significantly reducing future maintenance costs.

    Selection of high-quality imported and domestic materials. Scientific production processes and strict quality management guarantee the superior electrical performance of the heating tubes.

    Frequently Asked Questions

    What is the surface power capacity of these flange heaters?

    These flange heaters feature high surface power, capable of heating the air at 2 to 4 times the standard surface load.

    Do these flange heaters require brackets for installation?

    No, they do not require brackets. Due to their short, dense, and highly compact design, they offer excellent structural stability during installation.

    How are the heating tubes connected to the flanges?
