Technical field The invention relates to a high-temperature wear-resistant pipe fittings, pipeline is especially suitable for conveying dry coal-fired power plants and oil refinery circulating the catalytic cracking device in the delivery pipeline of the catalyst, and metallurgical, mining industry, heat of the powdery material or heat conveying granular material. Background technology The ash of the coal-fired power plants, the coal water slurry form to the pipeline for conveying and with high requirements to wear, and because of the fly ash is mixed with water temperature is reduced more, the high temperature resistance of the pipeline the low requirement of, the usual method is to adopt the steel with plastic liner in the pipeline for conveying of the composite pipeline, this kind of pipe better wear resistance, so that the service life is about 2 to 3 years. As the construction and other industries for the needs of dry coal ash the increase of the amount of, the vast majority of coal-fired power plant in the form of dry powder out of the coal ash, because the temperature of the dry coal ash usually more than 100 the [...] , some even reach 200 the above [...] , thus the original conveying coal water slurry of plastic-lined composite tube by not heat-resistant and not suitable for use. These power plants is to use ordinary steel or alloy steel pipe for conveying dry coal ash, although the steel tube has good high temperature resistance, however, the poor performance of friction-resistant, so the service life is relatively short, such as 20, of steel pipe number steel , after used for conveying dry coal ash, would not normally exceed one year service life. In the catalytic cracking device for delivery of catalyst circulation conduit, the alloy steel pipe is adopted, the need to bear up to the temperature of the 800 [...] , therefore the service life is relatively short.
