  1. Teflon electric heating tube

  The commonly used Teflon electric heating tube is a new type of strong corrosion-resistant electric heater made of tetrafluoroethylene sleeve, which is used for heating various corrosive liquids. It has excellent aging resistance and good bending performance, and adopts a low surface load design. Teflon electric heating tubes can be divided into two types, one is to spray the surface of the heating tube directly with fluoroplastic material, and the other is to cover the outer layer of the iron heating tube and the copper heating tube with a fluoroplastic sleeve.

  Pay attention to the following when using Teflon heating tube:

  1. To prevent the heated liquid from being too viscous, solid substances sticking to the surface of the pipe and burning out the Teflon

  2. It is recommended to add a temperature control protector to prevent the temperature from exceeding 110 degrees and burning the pipe

  3. Avoid disassembling the joint part voluntarily to prevent the penetration of acid

  4. It is best to control the power requirement below 1.5w/c㎡. The maximum should not exceed 2W/c㎡.

  Teflon electric heating tubes are used for heating, condensing, evaporating, etc. corrosive liquids such as electroplating, electrolysis, degreasing, pickling, electroless nickel plating, hydrofluoric acid, anodizing, aluminum plating, smelting, chemical industry, medicine, food, etc. The best heater choice for concentration and more!

  Performance of Teflon heating tube:

  1. Non-sticky: Teflon is inert, almost all materials are not bonded with Teflon, and the thin film also shows non-stick performance.

  2. Heat and cold resistance: Teflon has excellent heat and low temperature resistance. In a short time, it can withstand temperature to 300℃, melting point is 327℃, and it will not melt at 380℃. Generally, it can be used continuously between 240℃ and 260℃. It has remarkable thermal stability. It can work at freezing temperature. No embrittlement, cold resistance to 190℃.

  3. Lubricity: Teflon has a low coefficient of friction. The friction coefficient changes when the load is sliding, but the value is only between 0.04-0.15.

  4. Non-hygroscopicity: The surface of Teflon does not stick to water and oil, and it is not easy to stick to the solution during production operations. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving working hours and improving work efficiency.

  5. Corrosion resistance: Teflon is hardly corroded by chemicals, and can withstand all strong acids (including aqua regia), strong alkalis, and strong acids except molten alkali metals, fluorinated media, and sodium hydroxide above 300°C. The role of oxidants, reducing agents and various organic solvents can protect parts from any kind of chemical corrosion.

  6. Weather resistance: non-aging, the best non-aging life among plastics.

  7. Non-toxic: In normal environment within 300℃, it is physiologically inert, non-toxic and can be used as medical and food equipment.

  8. Insulation: Very good dielectric constant, high insulation.

  2. Teflon square tube

  Teflon square tube is a special tube made of polytetrafluoroethylene (PTEE commonly known as Teflon, plastic king) material after extrusion and sintering, drying, high temperature sintering, shaping and other processes.

  Teflon is currently widely used in important technology industries such as machinery, electronic appliances, automobiles, aerospace, chemicals, computers, electric heating, military, and communications.

  Features of Teflon square tube:

  1. High chemical stability: can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic solvents . It is very suitable for feeding high-purity chemicals.

  2. Low coefficient of friction: The coefficient of friction is generally only 0.04, which is a very excellent self-lubricating material, and the coefficient of friction does not change with changes in temperature.

  3. Excellent anti-sticking property, and the inner wall of the tube is not easy to adhere to colloids and chemicals.

  4. Excellent aging resistance, can be used outdoors for a long time.

  5. Excellent electrical insulation performance: PTFE is a highly non-polar material with good dielectric properties, extremely high electrical resistance, and a dielectric constant of about 2.0, which is small among all electrical insulation materials.

  6. Part of the tube has high transparency, and the internal fluid condition can be easily observed.

  Teflon square tube parameters:

  1. Withstand voltage: 150V-600V

  2. Working temperature: -80℃~260℃

  3. Melting point: 327℃

  4. Flame retardancy: VW-1

  5. Breakdown strength: 26KV/mm

  6. Color: milky white, transparent
