Electric heating tube is a tubular electric heating element, which is composed of metal tube, spiral resistance wire and crystalline magnesia powder. Electric heating tube products are generally made of high-quality imported stainless steel tube, imported high-temperature magnesia powder, high-quality electric heating wire and other materials, and other structural parts are made of stainless steel, which has excellent overall performance, super long service life and easy maintenance. High temperature resistance wire is evenly distributed in stainless steel seamless tube, and crystalline magnesia powder with good thermal conductivity and insulation performance is filled in the gap. The structure is not only advanced, but also has high thermal efficiency and uniform heating. When current passes through the high temperature resistance wire, the heat generated diffuses to the surface of metal tube through magnesia powder, and then transfers to the heated parts or air, To achieve the purpose of heating.
