Abstract
The utility model relates to a corrosion resistant composite pipe, which is composed of a basal layer (1) and a composite layer (2) which are compounded from outside to inside in turn, wherein the materials of the basal layer (1) adopt one of 20R, 16MnR or 15CrMnR. The materials of the composite layer (2) adopt 312. The pipe not only has high-strength and high pressure resistance performances, but also has corrosion resistant and high temperature-resistant performances. Thereby the pipe can be applied in transmitting media with higher demands to corrosion resistant and temperature-resistant performances.
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 corrosion-resistant composite pipe fitting corrosion-resistant, resistance to high temperature again.
The purpose of this utility model is achieved in that a kind of corrosion-resistant composite pipe fitting, and described pipe fitting is composited by basic unit and multiple layer to interior successively from outer,
Described base material adopts one of 20R, 16MnR or 15CrMnR,
Described plied timber adopts 312.
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.
