Abstract
The utility model relates to a steel tubular electric heater used for high-temperature and corrosive environment. The utility model is characterized in that the outer wall of a pipe body is additionally provided with an aluminizing layer. The radius of curvature R at the curve part of the pipe body is equal to or is larger than 2D. The utility model has the advantages of high temperature resistance, good corrosion resistant performance and low cost. The utility model is generally suitable for the industries of the chemical industry, the petrochemical industry, the medicament, etc.
Description
The utility model relates to a kind of steel tubular electric heating that is used for high temperature, corrosive environment.
Present electric heating tube adopts common steel tube or stainless steel tube manufacturing usually.In industries such as chemical petroleum chemical industry, medicine owing to have the work condition environment of high temperature and corrosion, as using ordinary carbon steel metal tube electric heater, then very fast can oxidation corrosion and scrap, as using stainless steel tube electric heater, just cost an arm and a leg, and also can produce corrosion.
The purpose of this utility model provides a kind of high temperature resistant, anticorrosion, long service life, the electric heating tube that price is lower.
The utility model is by body (5), and the resistance wire (3) in the fastener (2) of body (5) end, termination (1) and the body (5), filling insulant (4) are formed, and it is characterized by body (5) outer wall and are provided with aluminized coating (6).
Because the external wall surface of the utility model steel tube is provided with aluminized coating, the good price ratio stainless steel of resistance to elevated temperatures electric heating tube is low, particularly at H
2S, SO
2, CO
2, NH
3Use Deng in the corrosion body operating mode, have good corrosion resistance.
Accompanying drawing 1 is the utility model structural representation.
Further describe the utility model below in conjunction with accompanying drawing.
Body (5) is a steel garden pipe, and resistance wire (3) is positioned at body, and pipe is closely filled the insulant (4) with thermal conductive resin energy in resistance wire (3) and the body (5).Can fill insulant (4) earlier during making, crooked again body (5) also can bend to reservation shape with body (5) earlier to reservation shape, recharges insulant (4).The thickness of outside aluminized coating (6) is 0.10-0.30mm.For preventing aluminized coating (4) because of fragility cracks, the radius of curvature R 〉=2D of the bend of steel body (5), (D is the diameter of body (5)) is through evidence during as R 〉=2D, owing to the aluminized coating decreased performance that crackle produces can be ignored.Body (5) end is provided with fastener (2) and termination (1) as shown in the figure.
Claims (3)
1, the electric heating tube a kind of by body (5), that the resistance wire (3) in the fastener (2) of body (5) end, termination (1) and the body (5), filler (4) are formed is characterized by body (5) outer wall and is provided with aluminized coating (6).
2, by the described a kind of heating tube of claim 1, it is characterized by aluminized coating (6) thickness is 0.10mm-0.30mm.
3,, it is characterized by the radius of curvature R 〉=2D (D is the diameter of pipe (5)) of body (5) bend by claim 1,2 described a kind of electric heating tubes.
