The type of tubular heater
The type of tubular heater
Fin electric tube
Finned electric tube is a power consumption is converted into heat, to be heated material heating. In the work, the cryogenic fluid medium enters the input port through the pipeline under the pressure and along the specific heat exchange runner inside the electric heating vessel, the path designed by the principle of fluid thermodynamics is adopted, the high-temperature thermal energy generated in the work of the electric heating element is taken away, So that the temperature of the medium to be heated, fins heating tube exports get the high temperature medium process requirements. Fins tubular electric heating element, is wound on the surface of ordinary components metal heat sink, compared with ordinary components to expand the heat 2 to 3 times the surface area, that is, the allowable surface fin load power components is 3 to 4 times the normal components . As the length of the component is shortened, the heat loss of the device is reduced. Under the same power condition, the device has the advantages of rapid heating, high thermal efficiency, long service life, small heating device size and low cost. It can be installed in the air duct or other stationary, flowing air heating.
Flange heating tube
Flange heating tube (also called plug-in electric heater): U-shaped tubular heating element, according to the heating of different media design specifications, according to the power configuration requirements in the flange cover, insert the heating material, heating element work The heat generated by a large number of conduction to the medium to be heated to increase the temperature to achieve the required process requirements. When the medium temperature reaches the set value required by the process, the control system adjusts the output power of the electric heater according to the temperature sensor signal, and controls the temperature of the resistive load of the heating element. When the heating element over-temperature or low-level, heating element interlock protection device immediately cut off the heating power to avoid heating element burn, prolong the service life. Flange heating tube mainly for petroleum, chemical, food, machinery and other industries various types of storage tanks, containers, fuel tank material insulation and heating. Connection can be flanged or threaded face seal.
Titanium heating tube
Titanium electric heating tube is titanium tube shell, along the central axis of the tube uniformly distributed heating alloy wire gap filling compaction has good thermal conductivity of magnesia sand, both ends of the nozzle with silicone or ceramic seal, the metal electric heat Element-specific high-corrosive liquid. Titanium electric heating tube has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life. Widely used in a variety of highly corrosive liquids. Titanium with a small proportion, widely used in heating water, nitrate solution, acid solution, alkali solution, the practice proved that the titanium in the production of anti-corrosion equipment, high efficiency, long life, plating equipment applications, does not affect the bath Greatly improve the efficiency of electroplating industry. The effective length of the heating element must be fully immersed in the liquid to use.
Teflon
Teflon electric heating tube is a new type of electric corrosion-resistant heating tube, used for heating all kinds of corrosive liquids. Has excellent anti-aging and better bending performance, the use of low surface load design. The connector is fully enclosed anti-acid, non-heating section and overheating safety protection system in full accordance with the needs of customers. Perfect guarantee heater is not easy to burn, long life, sealed, non-corrosive, no leakage, with ground protection, safe and reliable. Suitable temperature below 110 ° C. Corrosion-proof Teflon electric heating tube with high thermal efficiency, energy saving, cost-effective advantages, can design a variety of structural forms, such as spiral type, L type, U type, W type, mosquito coils type, combination and so on. Has been recognized by a number of listed companies, and as its long-term supplier of mosquito coils Teflon electric heater. We can undertake non-standard products, voltage, power, size specifications and product shape, and wiring methods, in accordance with the requirements of customers so that engineers design, welcome to plans to OEM.
Quartz heating tube
Quartz heating tube, the most commonly used for carbon fiber heating tube.
Carbon fiber heating tube, also known as carbon fiber heating tube, infrared heating tube, infrared heating tube, carbon fiber infrared heating tube, carbon fiber infrared heating tube. It is placed in a quartz tube of carbon fiber wire, the tube vacuum sealed, the carbon fiber wire access voltage, the carbon fiber wire generates heat and heat. The company's products using imported carbon fiber heating body, with a large power headroom, high temperature, high heat capacity, long life, and the power can be adjusted and so on.
Radiant heat pipe
Radiant heating pipe is the electric heating element enclosed in the protective sleeve energized by the heat indirectly by the casing to the lining and the workpiece to be treated, are widely used in various heating furnace heat treatment industry. Electrolytic radiant heating alloy material used should have a higher resistivity, electrothermal conversion rate. Because the radiation tube is placed in the casing, the heat transfer process is different from that of the general exposed electric heating element. The heat shield is large. During the heating process, the temperature of the element must be controlled to prevent over-temperature of the element. Radiation tube closed heating, the heating element surface temperature higher than the furnace temperature of about 100 ℃ -150 ℃. Therefore, in the selection of materials to analyze the furnace temperature, furnace temperature atmosphere, choose the right heating material.
