U-shaped heating rod

The U-shaped heating element is a common electric heating component designed in a U-shape to enhance heating efficiency, widely used in industrial fields. Below is its core information:
Structural Features
U-shaped heating elements are typically made of electric heating alloy wires (such as nickel-chromium or iron-chromium alloy) wound around the surface of a metal tube (stainless steel, carbon steel), with both ends sealed with silicone and secured with a threaded structure. Their heat dissipation area is 2.5 to 4 times larger than that of ordinary smooth tubes, and their surface heat load is increased by 2 to 3 times, enabling rapid heating and maintaining high thermal efficiency.
Application Scenarios
Primarily used for moisture-proof heating in mechanical manufacturing, automotive, textile, food processing, spraying, and electrical equipment (such as switchgear and ring main units). In industrial circulation systems (such as storage tanks and containers), the U-shaped design optimizes heat distribution, ensuring uniform heating of the medium.
Wiring Methods
Single Wiring: Only requires one live wire and one neutral wire.
Multiple Parallel Connection: Connect head to tail and then to the power supply.
Series Connection: Connect all heating elements in series and then to the power supply.
U-shaped heating elements support customized power, size, and shape, with common forms including U-shaped and ring-shaped, meeting the needs of various industrial scenarios.
