The semi-circular electric heating tube structure is not only advanced but also has high thermal efficiency and even heat distribution. When current passes through the high-temperature resistance wire, the heat generated diffuses to the surface of the metal tube via an oxidized powder, then transfers to the heated object or air, achieving the heating purpose. Moreover, the surface is insulated and carries no charge during the power-on heating, ensuring safe operation.

The semi-circular electric heating tube boasts simple structure, long service life, high thermal efficiency, good mechanical strength, and the ability to be bent into various shapes while ensuring safety. It is commonly used for metal mold heating, die casting parts, centrifugal separators, dishwashers, immersion heaters, defrosters, and oven cabinets; it can be customized to specific lengths and is suitable for applications where small size and wiring at both ends are required. It is often used in mold making, mechanical manufacturing, metallurgy, conveyor belts, roller mills, and oven cabinets, offering high density and reliable installation.
