The tubular heater element is one kind puts in the resistance wire in the metallic pipe, and has the good thermal stability, the thermal conductivity in the periphery crevice part close packing and the insulation crystallization oxidation magnesium powder, again through other craft processing heater element.It has the structure to be simple, the mechanical strength is high, the thermal efficiency is high, safe reliable, the installment is convenient, service life long and so on characteristics.Widely uses in each kind of niter stone cistern, the water trough, the fuel tank, the acid and alkali trough heating and the air heating furnace, the drying oven, installments and so on hot mold.

Commonly used design reference data
1st, the tubular heater element surface power load and the tubing choice see also the heater element surface power load and the tubing chooses one chapter.
2nd, general tubular heater element smallest bevelling radius and biggest processing length.
3rd, general heater element engineering data
Dielectric resistance ≥1MΩ, dielectrical strength 2KV lasted 1min

Matters needing attention
★ Part permission in following condition work
a, the air relative humidity is not bigger than 95%, does not have the explosivity and the caustic gas
b, the working voltage should not be bigger than the rated value 1.1 times, the outer covering should earth effectively
★ When heating liquid, should give off heat the area to have effectively to plunge completely the liquid, forbid strictlys the spatial fever.Discovered the tube has when the boiler scale or ties the carbon, should promptly eliminate the clean use, in order to avoid affects radiates reduces the service life.
★ The heating fusible metal or the solid state nitre salt, the alkali, the asphalt, paraffin wax isochronism, should reduce the use voltage first, after treats the medium melting, can rise to the rated voltage.
★ When heating nitre salt should consider the security measure, prevented has the explosion accident.
★ When heating air the part should arrange evenly, enable the part to have the good radiation condition, causes has flowed air full heating.
★ The wiring part should place outside the heat insulating layer, avoids receiving superheat reduces the insulation.The wiring column should make an effort suitably.Prevented has made an effort fierce and destroys the screw.The wiring place should avoid with corroding, the explosive medium and the moisture contact.
★ The heater element should enter dryly in place, when use surveys the dielectric resistance.When is lower than 1MΩ, may put in 200℃ in about drying oven dry or through the low voltage heating, until restores the dielectric resistance.
★ Each kind of tubular heater element maximum temperature selects, see above table.
