Al2O3 ceramic tube
Product Description
Ceramic Tube:
Ceramic steel pipe is a kind of composite pipe made of ceramic and metal organic. The ceramic steel pipe combines the advantages of high hardness, chemical inertness and steel of alumina, and has excellent wear resistance, corrosion resistance, heat resistance and thermal shock resistance. Anti-mechanical impact performance, used in power plant coal powder, ash, mine ore, tailings, backfill, coal, concentrating plant coal, coking plant coke, sintering plant materials, life is 15 times higher than ordinary steel pipe It can also be used for the transportation of aluminum liquid and corrosive medium.
Properties:
1. Abrasion resistance: The Al2O3 content in the ceramic layer of
ceramic composite steel pipe is more than 90%, the microhardness is
HV1000-1800, so it has extremely high wear resistance, and its wear
resistance is higher than that of quenched medium carbon steel.
Double, better than tungsten carbide.
2. Corrosion-resistant ceramics are neutral materials with stable
chemical properties, excellent corrosion resistance and acid
resistance, resistance to various inorganic acids, organic acids,
organic solvents, etc., and their corrosion resistance is more than
ten times that of stainless steel.
3, excellent heat resistance, can withstand temperatures above 2000
° C, can work in the range of -50 ° C ~ 900 ° C for a long time.
4, easy to weld: ceramic-lined composite steel pipe can be welded
to the outer steel pipe to achieve the purpose of connection.
5, convenient transportation and installation: ceramic-lined
composite steel pipe and steel pipe, wear-resistant alloy cast
pipe, cast iron pipe and cast stone pipe, relatively light weight,
easy to transport and install. The ceramic-lined composite steel
pipe can be connected by welding, flange, flexible quick joint,
etc., and the installation is very convenient.
