Introduction: The stainless steel electric heating tube is made of metal tube, and the spiral electric heating alloy wire (nickel chrome, iron chrome alloy) is uniformly distributed along the center of the tube. The gap is filled with magnesia sand with good insulation and thermal conductivity. Silicon or ceramic seal. 220V stainless steel electric heating tube is an electrical component that converts electrical energy into heat energy. Because of its low price, convenient use, convenient installation and no pollution, it is widely used in various heating occasions. Stainless steel electric heating tube features: 1. The stainless steel electric heating tube is made of metal tube as the outer shell, and the spiral electric heating alloy wire (nickel chrome, iron chrome alloy) is uniformly distributed along the center of the tube. The gap is filled and compacted with magnesia sand with good thermal cond…
