Abstract

The utility model relates to a heating pipe coated with an enameled coating and consists of a ring flange, a U-shaped pipe and a straight pipe. An enameled coating is coated on the connected internal surface of the ring flange, the external surface of the U-shaped pipe and the external surface of the straight pipe. The separating end of the U-shaped pipe extends out of the ring flange and is welded at the seam joint on the external surface of the ring flange. One end of the straight pipe extends out of the ring flange and is welded at the seam joint on the external surface of the ring flange, and the other end of the straight pipe is sealed. The two extended ends of the U-shaped pipe and the extended end of the straight pipe are evenly distributed. The length of the U-shaped pipe and the straight pipe is between 200 to 1,000 millimeters. With the adoption of the enameled coating arranged on the external surface, the heating pipe coated with an enameled coating is greatly improved in the corrosion-resistant performance, the heating efficiency is hard to be reduced due to the deposition caused by the attached water scale and the service life of the heating pipe can be prolonged.

Description

A kind of heating pipe pipe fitting of coating enamel layer

Technical field

The utility model relates to a kind of electric heater, particularly a kind of heating pipe pipe fitting of coating enamel layer.

Background technique

Various electric heating tubes have been widely used in domestic hot water, industrial hot water, hot water field, public arena, also are applied to the needs to other liquid heating.

Electric heating tube is made up of heating core and heating pipe pipe fitting usually

At present, in order to improve the working life of electric heating tube, the skin of heating pipe pipe fitting normally adopts making such as electroplating processes, or even stainless steel.But these modes or cost are higher or need one electroplating work procedure, but a common problem is that corrosion resistance is not high, often there is incrustation scale to depend on, a lot of electric heating tubes usually arranged, with regard to incrustation scale is too much because outer surface depends on, heat conduction efficiency reduces and lost efficacy in length of life.

The model utility content

For remedying above-mentioned deficiency, the utility model provides a kind of can improve corrosion resistance, reduce the heating pipe pipe fitting of a kind of coating enamel layer that incrustation scale depends on.

The heating pipe pipe fitting of the utility model coating enamel layer comprises flange plate, U type pipe, straight tube, wherein, at the outer surface of the internal surface of the described flange plate that has connected, the outer surface of described U-shaped pipe, described straight tube one deck enamel layer is set.

The heating pipe pipe fitting of the utility model coating enamel layer, wherein: the separating end of described U-shaped pipe stretches out described flange plate and welds at described flange plate outer surface seam crossing, described straight tube one end stretches out described flange plate equally and in described flange plate outer surface seam crossing welding, the other end seals.

The heating pipe pipe fitting of the utility model coating enamel layer, wherein: two external parts of described U-shaped pipe and the external part of described straight tube evenly distribute.

The heating pipe pipe fitting of the utility model coating enamel layer, wherein: the length of described U-shaped pipe and straight tube is 200-1000mm.

The heating pipe pipe fitting of the utility model coating enamel layer, improved decay resistance greatly owing to the enamel layer of outer surface, and be difficult for depending on incrustation scale, also just be difficult for causing the problem of efficiency of heating surface decline, can prolong the working life of heating pipe pipe fitting because of the deposition of incrustation scale.

Description of drawings

Fig. 1 is the schematic representation of the heating pipe pipe fitting of the utility model coating enamel layer;

Fig. 2 is the flange plate end view of the heating pipe pipe fitting of the utility model coating enamel layer.

Embodiment

For further setting forth the heating pipe pipe fitting of the utility model coating enamel layer, do more detailed explanation below in conjunction with embodiment.

Fig. 1 is the schematic representation of the heating pipe pipe fitting of the utility model coating enamel layer, and is the same with the heating pipe pipe fitting of general coating enamel layer, is made up of flange plate 1, U-shaped pipe 2 and straight tube 3.Two one section outer surfaces that stretch out flange plate 1 that separates termination and straight tube 3 of U-shaped pipe 2, in the seam crossing welding of flange plate 1 outer surface, the other end sealing of straight tube 3; Two external parts of U type pipe 2 and the external part of straight tube 3 even distribution (see figure 2) (this only is an embodiment, and in the reality, the quantity of U-shaped pipe 2 and straight tube 3 can be more than, can establish two, three as required) on flange plate 1; Several fixed holes 5 are arranged on the edge of flange plate 1.

Afterwards, be coated with last layer enamel layer 4, the sintering typing at the inner surface of flange plate 1, the outer surface of U-shaped pipe 2, the outer surface of straight tube 3.

Improve decay resistance greatly owing to enamel layer, and be difficult for depending on incrustation scale, just can prolong the working life of the heating pipe pipe fitting of coating enamel layer.Be noted that it to be to carry out sintering enamelled processing on the whole, can't weld because applied the parts of enamel layer at the good heater pipe fitting of welding; Enamel layer will play antiseptic and rustproof effect simultaneously in addition, therefore at the water receiving face, should not stay any gap that does not have enamel layer.

The length of U type pipe 2 and straight tube 3 can be at 200-1000mm.

U type pipe 2 and straight tube 3, also also nonessential use simultaneously only selects for use U type pipe 2 or straight tube 3 (such as two straight tubes) passable equally.

The heating pipe pipe fitting of ready-made coating enamel layer, the heating core of packing into just becomes a complete electric heating tube.
