The single-head electric heating tube with built-in thermocouple is a high-load electric heating element. Our company adopts seamless stainless steel tube, and in accordance with the product's working condition, the surface temperature of the tube is very high, and the thermal insulation and leakage current requirements, the internal design uses high temperature resistant magnesium oxide rod, anti-oxidation nickel complex heating wire. The design of tubes are fully considered the installation and use environment, and maintains the standardized degree of pipe diameter. We insist that meet the customer's needs for the safety and life of equipment heating elements.
