What is a Tubular Heater?

Conceptually, an electrical resistance is any opposition that occurs and that the current encounters when passing through a closed electrical circuit, which is why it attenuates or slows down the flow of the circulation of the electric charge or electrons involved.

How does an electrical resistance work?
We must begin by knowing that the electrons will circulate through an electrical circuit in a more or less organized way, depending on the resistance they encounter along the way. Likewise, the lower the resistance, the more order will be given between the electrons, while a high resistance will cause the electrons to collide with each other and the energy will be released as heat (heat energy).
In a situation like the one described, it is always caused that the conductor temperature rises somehow and in turn has higher values, at a point where the electrons will meet a higher resistance in its path.

Where can we see an electrical resistor?
Almost all electrical appliances need an electrical resistor to release the excess energy that their operation accounts for, which involves an expulsion of heat energy; to name a few

DOMESTIC SECTOR
-Heat gun.
-Electric shower.
-Electric stove.
-Electric grill.
-Bread toaster.
-Water heater.

INDUSTRIAL SECTOR
-Water Heating
-Fluid Heating
-Gas Heating
-Piping Temperature Maintenance

ELECTRICAL RESISTANCE IN INDUSTRY
According to what has been explained above, we can describe resistance as the opposition of electrons in a circuit. Now, the electrical resistance can be found in both domestic and industrial places.
Comind Industries, has focused on the manufacture of electrical resistors at industrial level for all sectors such as mining, agro-industrial, food, petrochemical, etc.
Throughout its 30 years the main method of electrical resistance used in industry is the tubular resistor.

WHAT IS A TUBULAR RESISTOR?
Before explaining the process we can determine the main raw materials for the manufacture of a tubular resistor.

Nickel chromium wire
Nickel chromium wire is an alloy rich in Ni (80%) which together with Cr (20%) provides an excellent conductor for heat generation in heating systems.

Stainless Steel Pipe
Stainless steel pipe offers significantly greater resistance to corrosive elements, oxidation, erosion and high temperatures than most metal pipes. Also, because it resists elements as corrosive as those often found in seawater environments, stainless steel tubing is the best choice for shipbuilding and marine applications.

Magnesium Oxide
Magnesium oxide is widely used as an insulator for the manufacture of high temperature compacted elements. The reason why magnesium oxide is used for these purposes and the dielectric nature at high temperatures is explained in detail.
It is well known that the compacted mineral (common name for magnesium oxide) is used as electrical insulation in various applications such as industrial wiring, thermal heating elements, thermocouple and RTD sensor manufacturing in general.
In all these applications magnesium oxide provides high thermal stability, radiation tolerance and high electrical resistivity at temperatures up to 1008ºC. Although there are other materials that are sometimes also used as electrical insulators, magnesium oxide is by far the most widely used industrially.
