Abstract
The utility model relates to a high temperature-resistant compound tube which is formed by a base layer (1) and a compound layer (2) from the outside to the inside; the material of the base layer (1)comprises 20R, 16MnR or 15CrMnR, and the material of the compound layer (2) comprises 304, O0Cr19Ni10, 312, O0Cr17Ni14Mo2, 317L or 0Cr13Al. The compound tube has the advantages of high strength, highpressure resistance, corrosion resistance and high temperature resistance, thus being applicable to the transportation of media which have higher requirement on corrosion resistance and high temperature resistance.
Description
Technical field
The utility model relates to a kind of pipe fitting.Be widely used in industry fed sheet of a media such as oil, chemical industry, electric power, boats and ships, metallurgy, machinery, weaving, food, building, pharmacy.Belong to the pipe fitting technical field.
Background technique
Before the utility model was made, traditional pipe fitting was generally made by 20R, 16MnR or 15CrMnR.This class pipe fitting intensity height, withstand voltage properties are strong.But corrosion-resistant, resistance to high temperature a little less than, therefore can only be used for the conveying of general medium, and can not be used for conveying the medium corrosion-resistant, that resistance to high temperature has higher requirements.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of both had high strength, high withstand voltage properties are provided, and has high temperature resistant composite pipe fitting corrosion-resistant, resistance to high temperature again.
The purpose of this utility model is achieved in that a kind of high temperature resistant composite pipe fitting, and described pipe fitting is composited by basic unit and multiple layer to interior successively from outer,
Described base material comprises 20R, 16MnR or 15CrMnR,
Described plied timber comprises 304,00Cr19Ni10,312,00Cr17Ni14Mo2,317L or 0Cr13Al.
The utlity model has following characteristics:
1, intensity height, withstand voltage properties are strong
The utility model base material adopts 20R, 16MnR or 15CrMnR, and intensity height, withstand voltage properties are strong.Therefore can guarantee the requirement of pipe fitting to intensity and withstand voltage properties.
2, corrosion resistance, heat-resisting quantity are strong
The utility model plied timber adopts 304,00Cr19Ni10,312,00Cr17Ni14Mo2,317L or 0Cr13Al, and corrosion resistance, heat-resisting quantity are strong.Therefore can guarantee the requirement of pipe fitting to corrosion resistance, resistance to high temperature.
