Alumina Ceramic Tubes and Pipes with Flanges for Connection and Sealing

Alumina ceramic flange pipe refers to an alumina ceramic pipe with an integrated flange structure at one or both ends. This flange is typically integral to the pipe body and manufactured through a special ceramic molding and sintering process. Its primary purpose is to facilitate and reliably connect bolted connections to other metal flanges in the piping system.

This pipe differs from "flange-mounted ceramic-lined composite pipe," which features a metal outer shell with a flange and an internal ceramic lining.

1. Fully Ceramic Flow Path, Ultimate Performance:
The entire inner wall of the pipe is constructed of high-purity alumina ceramic, providing uniform and optimal wear resistance, corrosion resistance, and insulation. No metal parts are exposed to the media, preventing metal contamination and electrochemical corrosion.

2. Excellent Sealing:
The flange end faces are precision-ground for an exceptionally smooth and flat finish. When combined with metal flanges and gaskets, they provide an excellent seal, particularly effective in preventing leakage of powdery or fine particle media.

3. Eliminate the Risk of Liner Detachment:
Compared to "ceramic-lined composite pipe," this pipe features a monolithic structure, eliminating the risk of ceramic lining detachment under the impact of high-speed, abrasive media, resulting in extremely high reliability.

4. Convenient Installation:
It connects directly to the opposite flange via bolts, and installation is identical to traditional metal pipes, making it extremely convenient and quick.

Alumina ceramic flange pipes are primarily used in high-wear applications requiring extremely high sealing, corrosion resistance, and contamination prevention:

1. High-purity material transportation:

• Semiconductor industry: Transportation of high-purity silicon powder, CMP slurry, and other materials requiring zero metal contamination and excellent wear resistance.
• Lithium battery material industry: Transportation of positive and negative electrode material powders such as lithium iron phosphate, lithium cobalt oxide, and graphite.
• Food and pharmaceutical industries: Transportation of certain abrasive raw materials requiring zero metal contamination.

2. Highly corrosive and abrasive working conditions:

• Chemical processes involving the transportation of media subject to both strong acid and alkali corrosion and abrasive solid particles.

3. R&D areas requiring absolute zero metal contamination:

• Various laboratories and pilot and test facilities.
