reasonable, the heater adopts multiple protection, which greatly
increases the safety and life of the heater.
7. Dry stainless steel electric heating pipe based on metal shell,
along the axial uniform spiral tube center electric thermal bonding
wire, nickel chromium, iron chromium alloy) the gap filling
compaction with good thermal conductivity of insulating oxide
magnesia, using silica gel or ceramic seal on both ends of the
tube, the metal armoured electric heating element to heat the air,
metal molds and all kinds of liquid. ] Evenly distributed in the
high temperature resistant stainless steel seamless tube of high
temperature resistance wire, dense part in gap to fill in the
performance of thermal conductivity and good insulation performance
are the crystallization of magnesium oxide powder, this kind of
structure not only advanced, high thermal efficiency, and even
heating, when high temperature resistance wire in an electric
current passes through the heat to the metal surface diffusion
through crystallization of magnesium oxide powder, Then transfer to
the heated parts or air to achieve the purpose of heating.

3, high power, is 2-5 times the power of the normal dry burning
electric heating tube, can do (surface area of 20 watts/square
centimeter), even foreign can do (surface area of 60 watts/square
centimeter).

efficiency, safe and reliable, simple installation, long service
life, no pollution, cheap and other characteristics, at the same
time save electricity, safe use, can be bent into a variety of
shapes, light, convenient disassembly and assembly.
Dry burning electric heating tube structure:
The typical structure of dry burning electric heating tube (the
most popular structure) is the same as that of dry burning electric
heating tube. It is generally composed of five parts: insulator,
sealing material, lead rod, filling material, electric heating
wire, metal casing and wiring end. The spiral electric heating wire
and lead out help are located in the central metal casing, its
manufacturing process is to spiral electric heating wire into
seamless steel tube, copper tube or aluminum tube, the gap through
the multi-tube filling machine evenly filled both insulation and
heat conduction of oxidation medium, such as crystalline magnesium
oxide powder (also available alumina or clean quartz sand). Then
use the tube shrinking machine to shrink the tube diameter, so that
the oxide medium is dense (density of 3.3g/cm3 or more), to ensure
that the heating wire is isolated from the air, the central
position does not offset and touch the tube wall. Like this. Unit
area calorific value can increase ten times. Service life can also
be correspondingly increased to more than 10 years. Compared with
the heating element with the same amount of heat, the tubular
dry-fired heating tube can save 5% of the heating material, and the
thermal efficiency can reach more than 90%.
Dry burning electric heating tube difference:
1, appearance: dry electric heating tube is one end (one end),
ordinary dry electric heating tube is two ends of the line.
2, internal structure: the winding way of dry burning heating tube
and ordinary dry burning heating tube is different, especially now
the imitation of imported U-type electric head tube, and ordinary
dry burning heating tube has a great difference.
3, production process: dry burning electric heating tube in the
production process than ordinary dry burning electric heating tube
has more technology, such as shrinkable tube, which ensures that
the power of dry burning electric heating tube is higher than
ordinary dry burning electric heating tube, and the service time is
long
