Every industry in today’s world is utilizing the some or other form of heating applications. The heating is very much a part of our day to day life. As the dependency on heating application grows, there is a serious concern also expressed related to safety and environmental impact as well as efficiency of the many of the heating solutions being used. While some of the systems have a risk of fire accidents, many of the other conventional system generate a lot of carbon dioxide and other gases that contaminate the environment. Tubular Electric heater is a one of the Best option for the modern world, which is safest way to heat any fluid or surface without creating gases or hazardous releases.Tubular heaters are typically manufactured using a resistivity coil placed inside a Metal tube and filled inside with insulating materials such as Magnesium oxide. The heating coil placed at the center with uniform pitches, separated from the outer metal sheath by a compacted Magnesium oxide ensures that No electric shock is transferred to the outer surface. At the same time the all the heat energy produced is transferred to the process through outer body. Hence the Heater is regarded as one of the highly efficient and safe way of heating.Construction Nickel Chromium Resistance were uniformly coiled wire is stretched through the active length of the element. The ends are proved with the terminal pins to create cold ends. Magnesium oxide:High purity magnesium Oxide power is filled between the coil and outer tube in a automated filling station to ensure the right insulation, conduction as well as compactness. Outer sheath: Tube (welded or seamless) which acts as a outer protection for the heating Element. Selection of outer tube depends on various factors such as temperature, pressure, fluid to be heated etc. Terminal pins: Also known as terminal pins are extended ends of the heating elements. The SS rods of a specific diameter are fusion welded to the coils at both ends. The length of the rod depends on the nonheating length required for any application and installation. End Sealing: Sealing is done using the combination of Ceramic beads, soft seals & sealants. The sealing ensures that no moisture from the atmosphere enters the heating element and keeps it dry. End Seal Options Teflon Seal: Teflon seal is used where effective sealing is required against moisture and oil contamination. Silicon Rubber Seal: Most popular and highly used sealing method. The sealing can withstand up to 200 deg C temperature and provides long lasting moisture protection. Epoxy Seal: Epoxy potting forms a good moisture seal with more mechanical strength than a silicon rubber seal. Recommended for a system assembly with large no of tubular elements. Cement: recommended for the heater which operates at very high skin temperature. Provides protection against high viscous fluids and dusts. The top layer can be provided with additional insulation to make it moisture resistance as well.

Known for its versatility, ruggedness and dependability, tubular heaters can virtually be factory-configured to suit a variety of industrial heating applications. Tubular elements are frequently regarded as the foundation of all heating elements. The basic design consists of a resistance wirecoil precisely centered in a metal sheath. This wirecoil is surrounded by magnesium oxide to provide efficient heat transfer from coil to heating medium. Diameters are varied to give customized design and adjustable watt densities for best performance and long life. Bending radius is carefully chosen so as to give optimum performance. Tubular heating elements perform heat transfer by all three modes (conduction, convection and radiation). They are available in both single ended and double ended designs. The single-ended tubular design has both terminals at one end. The opposite end is sealed. Flexible lead wires are 12 in. (305 mm) crimp connected to the terminal pin and have silicone-impregnated fiberglass over-sleeves. Maximum watt density is up to 45 Wsquare inch while the maximum operating temperature is 1200 degree F, so INCOLOY and stainless steel sheaths can be used. The double-ended design has rounds cross sectional geometry, is highly adaptable for bending—especially when bending is performed in the field. Double-ended tubular elements offer several assemblage of resistor coils and thermocouples inside one sheath. They have the ability to sense the heater’s internal temperature accurately every time, or offer three-phase capability in one element. Maximum watt density is up to 120 Wsquare inch while the maximum operating temperature is 1800 degree F, so INCOLOY and stainless steel sheaths can be used.
