Integral calcined ceramic lined pipe is made by integrally firing ceramic pipe fittings, and casting ceramic pipes with special filling materials inside the steel pipe for assembly. The alumina content of the ceramic fittings lined with alumina ceramic pipes is not less than 95%. 200T dry press forming, sintering temperature up to 1670 ℃. Its advantages are: smooth inner wall, good sealing, and very good wear resistance and corrosion resistance.
Craftsmanship
According to the mold, the ceramic powder is sintered into a ceramic pipe, and then combined with the steel pipe. The outer wall and inner wall of the alumina ceramic pipe are assembled with special filler (cement or epoxy resin) inside the steel pipe, and then formed by isostatic pressing. In the sintering process, the furnace cools down quickly, is easy to crack, and the process is more complicated. The pipes are generally white.
Integral calcined ceramic pipeline process
Desulfurization ceramic wear-resistant pipes are assembled by firing ceramic pipe fittings as a whole, and pouring the shaped ceramic pipes inside the steel pipe with special fillers. The alumina content of the ceramic pipe fittings lining the desulfurization wear-resistant pipeline is not less than 95%. 200T dry pressing, sintering temperature is as high as 1670℃. Its advantages are: smooth inner wall, good sealing, and very good wear resistance and corrosion resistance.
Production Process of integral calcined ceramic lined pipe

The outer wall of the ceramic pipe and the inner wall of the steel pipe are assembled by pouring a special filler (cement or epoxy resin) inside the steel pipe, and then isostatically pressing. During the sintering process, the furnace cools quickly, cracks easily, and the process is more complicated. The pipe is generally white.
