Shape Bended Tubular Heating Element is a versatile electric heating element, typically made of metal tubes such as stainless steel, copper, or aluminum, with a resistance alloy wire inside. Its key feature is the ability to be bent into various shapes according to specific heating requirements and installation spaces.
Operating Principle:
The bended tubular heating element generates heat as electric current flows through the resistance alloy wire. These heating elements are encapsulated in a metal tube, with the outer surface of the tube often made of high-temperature-resistant materials to ensure effective heat transfer and protect the heating element from damage. The bent design allows the heating element to be more flexible and adaptable to different installation requirements, especially in confined spaces.

FAQ:
1. If I have a sample from another company, can BAILIHAO make it?
Our facilities offer the flexibility of making most any heater in the market. We would normally require the drawings and specifications to be sent to us to verify dimensions, power rating etc…
2. What kind of electric heaters do I need?
Depending on your application, there are a variety of different models to choose from. For smaller applications, screw plug heaters are useful for their low cost and ease of replacement. For larger applications flanged heaters and circulation heaters are used for their ability to handle high loads of power and larger volume of liquids. For heaters that heat gas, duct heaters are practical. If there is a pressure requirement, it is recommended to use a pipeline circulation heater. Each product has the option of coming with a mechanical thermostat or a digital controller for more precise temperature requirements. Standard junction box is always available, moisture-proof, and explosion-proof housing for more volatile environments.
3. What is Watt density?
Watt density (WPSI) is a term used in the heating industry that describes the amount of permissible wattage over a surface area of a heater. Water has a typical watt density of 65 WPSI whereas Oil would have much less because of its viscosity. When ordering a heater, it is always important to indicate to our sales group the medium for which you are heating. Typically when you are heating unclean filmy water it is important to maintain the cleanliness of your tank and consider watt density as a way to help prolong your heaters life. If deposits are in contact with the tubular element, they will stick to the sheath and will eventually lead to failure because the heat from the inner tubular coil cannot dissipate into the liquid medium easily.
4. Brand Description of Heating Elements and Accessories
Because we are a manufacturer of heaters, all components and equipment are non-standard customized products (except some parts). For replacement brand of corresponding electronic components (Siemens, etc.), please be sure to tell our sales team.
5. How often should I maintain the heater?Heaters should be maintained on a regular basis, depending on the medium you are heating, each application should be thought out carefully. Water-based liquids might have calcium deposits that stick to the sheath and, would require frequent maintenance to prevent calcium deposits (normally identified as a white powdered substance) from sticking to the individual elements.
6. Freight and Trade Agreements For some large-scale heating equipment, the shipping price is based on the size in the drawings to estimate the real-time shipping cost, and does not represent the shipping cost on the day of shipment. Therefore, there will be deviations in freight charges, (except for the client's agent receiving packages) At present, ordinary orders only support EXW, FOB, CIF, and special orders can be negotiated.
