Description

High-temperature-resistant steel pipe

Technical Field

The utility model relates to a perambulator small-bore steel pipe processing technology field specifically is a high temperature resistant steel pipe.

Background

The baby carriage can be divided into various types, mainly according to the standard of load capacity, the general test standard is nine to fifteen kilograms, the general baby carriage can be used for about four to five years, the small-caliber steel pipe of the baby carriage can be processed at high temperature in the production process, and when the temperature is too high, the steel pipe can deform to cause the product to be unqualified.

The main component of the existing small-caliber steel pipe is iron, the strength of the steel pipe gradually decreases along with the increase of the temperature, and the existing steel pipe product can deform at a high temperature and is not beneficial to ensuring the product quality.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a high temperature resistant steel pipe has solved the not high problem of current steel pipe high temperature resistant degree.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a high temperature resistant steel pipe, includes the body, a plurality of outer ceramic plates have been buried underground to the surface of body, the inside interior ceramic plate that has been buried underground of body, through ceramic post fixed connection between interior ceramic plate and the outer ceramic plate.

Preferably, the outer surface of the pipe body is coated with an epoxy zinc-rich primer layer.

Preferably, the inner wall of the pipe body is sprayed with an alloy spraying layer.

Preferably, the thickness of the epoxy zinc-rich primer layer is 0.05mm-0.1 mm.

Preferably, the thickness of the alloy sprayed layer is 0.1-0.15mm, and the material of the alloy sprayed layer is nickel-based alloy.

Advantageous effects

The utility model provides a high temperature resistant steel pipe. The method has the following beneficial effects:

this high temperature resistant steel pipe through the outside at the body and the inside ceramic plate of having buried underground, the ceramic plate is slightly higher under high temperature, carries out high temperature processing when the steel pipe, and the intensity of steel pipe descends, and the ceramic plate plays the effect of support, prevents that the steel pipe from warping, guarantees the quality of product.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a pipe body; 2. an outer ceramic plate; 3. an inner ceramic plate; 4. an epoxy zinc-rich primer layer; 5. and (5) spraying an alloy layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a high temperature resistant steel pipe, includes body 1, a plurality of outer ceramic plates 2 have been buried underground to the surface of body 1, body 1 is inside to be buried underground has interior ceramic plate 3, through ceramic post fixed connection between interior ceramic plate 3 and the outer ceramic plate 2, add man-hour, under the superhigh temperature, the temperature of body 1 is too high, slightly can greatly reduced, outer ceramic plate 2 and interior ceramic plate 3 can chucking body 1 to prevent body 1 bending, greatly increased the life and the result of use of steel pipe under the high temperature condition.

Wherein the surface spraying of body 1 has epoxy zinc-rich priming paint layer 4, and epoxy zinc-rich priming paint layer 4 can reduce the overlook degree of steel pipe when transporting or placing.

Wherein the inner wall of the pipe body 1 is sprayed with an alloy spraying layer 5.

Wherein the thickness of the epoxy zinc-rich primer layer 4 is 0.05mm-0.1 mm;

the paint film has high zinc powder content, has a cathode protection effect and excellent water resistance, reduces the corrosion of a steel pipe when the baby carriage washes the baby carriage, and prolongs the service life of the baby carriage.

Wherein the thickness of the alloy spraying layer 5 is 0.1-0.15mm, and the material of the alloy spraying layer 5 is nickel-based alloy;

the nickel-based alloy has higher corrosion resistance and high temperature resistance, ensures that the interior of the steel pipe is not corroded, and prolongs the service life of the steel pipe.
