Flanged Tubular Heaters: Versatile Solutions for Industrial Heating

Tubular heaters with flanges are essential components in many industries because of their versatility, customization, and ability to work in strict conditions. These heaters are built by brazing or welding flanges using various hairpin or bulge tubular elements. They are used for heating chemicals, petroleum, water, heat transfer fluids, light to medium-weight oils, and water in tanks as well as pressure vessels. This blog will explore more on the technicality of the flanged tubular heaters, their features, uses, and their importance in industries.

Construction and Design

Flanged tubular heaters are assembled by connecting hairpin or bulge tubular elements to a flange by brazing or welding method. The design allows heat exchange and simplicity in fixing the cooling system. These heaters usually have thermocouples or resistance temperature detectors (RTDs) installed in the bundle of elements for the purpose of maintaining the required temperature. A thermowell is used to protect these sensors and heating elements.

Different types of alloys and materials are used in the production of flanged tubular heaters for different uses. For instance:

Steel flanges: Deionized water, Crude and refined oils, Waxes, Mildly Corrosive Fluids, and Low-Flow Gas & Water Tank Heating all require steel flanges.

Stainless steel flanged heating elements: Mild and Severe corrosive solutions and military applications require Stainless steel flanged heating elements.

Sheath materials: Sheath materials are steel, stainless steel, copper, as well as more specialized alloys such as Incoloy with their various operating temperatures and watt densities.

can include steel, stainless steel, copper, and exotic alloys like Incoloy, each offering different operating temperatures and watt densities.

Material Selection and Specifications

It is very important to choose the right material for the flanged tubular heaters. The following table provides a quick reference for the maximum operating temperatures and watt densities of various sheath materials:

When it comes to selecting the sheath material the required operating temperature and watt density should be within the range of the specified application.

Key Features of Flanged Tubular Heaters

Flanged tubular heaters are characterized by several features that make them useful in a range of industrial procedures. Some notable features include:

Lightweight and Portable: These heaters are easy to install and remove as well as easy to maintain.

Moisture Proof: Available in moisture-proof models to prevent damage in humid environments. Moisture-resistant models prevent damage in the case of moist conditions.

No Drilling Required: It is easier to install with less time to set up the system and reduces cost of labour

Uniform Temperature Control: It maintains heat throughout the area of application and with minimal heat loss.

Oxidation and Corrosion Resistant: Improves strength and wear resistance even in a harsh environment.

Safety and Durability: Constructed with value and durability for long-time usage.

Applications of Flanged Tubular Heaters

Flanged tubular heaters are very versatile and can be used in numerous applications in medium and large industries. Some typical applications include:

Clean Water and Hot Water Storage: Copper sheath with steel flange suitable for potable water, freeze protection, and hot water storage.

Steam Boilers and Mildly Corrosive Solutions: An incoloy sheath with steel flange is appropriate for use in steam boilers, rinse tanks, spray washers, and vapor degreasers.

Oil and Gas Heating: A steel sheath with steel flange is recommended to for light-medium oil, gases, hydraulic oil, stagnant heavy oil, lubricating oils and crude asphalt.

Process Water and Chemical Baths: A stainless steel sheath with a stainless steel flange is ideal for process water, washing solutions, boilers and water heaters and deionized water.

Severe Corrosive Solutions: Incoloy sheath with stainless steel flange is employed when there is severe corrosive solutions and demineralized water.

Maintenance and Customization

Flanged tubular heaters must be checked regularly and cleaned to guarantee it is in the best shape and condition. The heaters can be customized with regard to terminal enclosures for wiring, baffles, and flange mountings. These heaters are usable with control panels and can work combined with them to attain the desirable temperature.

Conclusion

Flanged tubular heaters are very flexible, adaptable, and can be used for many different heating applications. Their material, construction, and design make them capable of use in various applications, including heating clean water to highly corrosive fluids. By understanding technicalities and choosing the appropriate material industries can enhance the performance and life expectancy of flanged tabular heaters.
