Abstract

The invention discloses a high-temperature-resistant and corrosion-resistant pulverized coal boiler pipe material, wherein the high-temperature-resistant and corrosion-resistant boiler pipe material consists of the following components in parts by weight: 3-8 parts of curing agent; 12-15 parts of turpentine 1-3 parts of toluene; 2-7 parts of barium sulfate; 8-15 parts of sulfur; 2-6 parts of magnesium oxide; 8-10 parts of universal carbon black; and 25-42 parts of calcium carbonate. The invention provides a high-temperature-resistant and corrosion-resistant pulverized coal boiler pipe material. The boiler pipe using the material works under the action of high temperature, stress and corrosive medium, and is not only resistant to high temperature, but also not easily oxidized and corroded.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a pulverized coal boiler pipe material with high temperature resistance and corrosion resistance. Background technique [0002] Boiler pipes include heating surface pipes and steam pipes. These pipes work for a long time under the action of high temperature, stress and corrosive media, which will cause creep, oxidation and corrosion. If the outside of the pipe is affected by high-temperature flue gas, high-pressure steam flows in the pipe, and the temperature of the pipe wall is 50 to 80 degrees higher than the temperature of the steam. The existing materials for making boiler pipes are not resistant to high temperature, and are easy to oxidize and corrode. [0003] From the above, it is necessary to need a pulverized coal boiler pipe material with high temperature resistance and corrosion resistance. Contents of the invention [0004] The object of the present invention is t...
