A method for manufacturing a herringbone monolithic composite ceramic tube

Abstract

The application discloses a preparation method of a herringbone integral composite ceramic pipe, which comprises the following steps: (1) adopting a grouting process to cast ceramic into a prefabricated mold, and then high-temperature sintering to form a herringbone integral ceramic lining; (2) respectively cutting two metal elbows along the axial direction of the inlet center, splicing together for welding to form a herringbone integral metal pipe, and then cutting the herringbone integral metal pipe along the axial direction into two halves; (3) placing the herringbone integral ceramic lining in the middle of the two herringbone integral metal pipes, and then splicing together for welding to obtain a herringbone integral composite ceramic pipe. The herringbone integral composite ceramic pipe has the advantages that compared with a traditional T-shaped right-angle three-way pipe, fluid resistance is smaller, service life is longer, the ceramic lining is integrally sintered, there is no splicing gap between ceramics, the ceramics are closely combined with the metal pipe, the ceramics are not separated, wear resistance is good, and the herringbone integral composite ceramic pipe can be used in high-temperature or strong-corrosion working conditions.
