The semi-circular electric heating tube structure is not only advanced with 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 through oxidation of the powder, then transfers to the heated object or air, achieving the heating purpose. Moreover, the surface remains insulated and non-conductive during the power-on heating, ensuring safe operation.

The semi-circular electric heating tube features simple structure, long lifespan, high thermal efficiency, good mechanical strength, can be bent into various shapes, and ensures safety, making it suitable for metal mold heating, die casting, rolling mill, dishwasher, immersion pot, defrosting, oven cabinets, etc. It can be customized to various lengths as per requirements and is ideal for applications where a smaller size is needed and wiring is required at both ends. It is commonly used in mold-making, mechanical manufacturing, metallurgy, conveyors, roller mills, and oven cabinets, boasting high density and reliable installation.
