U-shaped heating tube is also called anisotropic heating tube. High-temperature resistant resistance wires are evenly distributed in the seamless stainless steel tube, and crystalline magnesium oxide powder with good thermal conductivity and insulation performance is densely filled in the gap. This structure is not only advanced, but also has high thermal efficiency and uniform heating. When the current passes through the high-temperature resistance wire, the generated heat diffuses to the surface of the metal tube through the crystalline magnesium oxide powder, and then is transferred to the heated part or water to achieve the purpose of heating.

brief introduction

U-tube

U-shaped electric heating tube is made by putting electric heating wire into seamless metal tube (carbon steel tube, titanium tube, stainless steel tube, copper tube) and closely filling the gap with crystalline magnesium oxide with good thermal conductivity and insulation. The two ends of the heating wire are connected with the power supply through two lead-out rods, the gap is filled with magnesium oxide powder with good thermal conductivity and insulation, and then the tube is shrunk. Because the electric heating tube is bent like the English letter U, it is called a U-shaped electric heating tube.

trait

Simple structure, high thermal efficiency, good mechanical strength and strong adaptability to harsh environment. U-shaped electric heating tube can be used to heat all kinds of liquids, acids, alkalis and salts, and is also suitable for heating and melting low melting point metals (lead, zinc, tin and babbitt alloy).
