Description
Technical field
This utility model relates to corundum pipe elbow technical field, is specially a kind of corundum pipe elbow.
Background technology
Along with China's rapid development of economy, pipeline carries throughout industries such as electric power, metallurgy, petrochemical industry, coals, when the material that the grindabilities such as pipeline Nei Shu road lime-ash, coal dust, tantalite power are big, all there is the problem that pipe wear is fast, particularly bent wear is faster, when carrying the gas of strong corrosion, liquid or solid in pipeline, there is pipeline to be corroded and the problem damaged, when conveying has the material of higher temperature in pipeline, there is the use expensive problem of heat resisting pipe.Therefore country be badly in need of at present a kind of can be with high-temperature corrosion resistance, high temperature resistant corrode and wear-resistant pipeline, especially for connecting the elbow of pipeline, performance is more preferable these functions that could realize than straight pipeline, increase pipeline service life.
Summary of the invention
The purpose of this utility model is to provide a kind of corundum pipe elbow, is weak to, with the pipe elbow solving to propose in above-mentioned background technology, the problem that corrosion, wear is fast and high temperature corrode is fast.
For achieving the above object, this utility model following technical scheme of offer: a kind of corundum pipe elbow, including ceramic composite steel pipe end face of elbow, described ceramic composite steel pipe end face of elbow is provided with nut connector, and ceramic composite steel pipe end face of elbow is arranged on the two ends of seamless steel pipe elbow, the surface of described seamless steel pipe elbow is provided with reinforcement, described seamless steel pipe elbow is made up of corundum layer, alumina ceramic layer and steel plate layer, and corundum layer is arranged on the interior surface of alumina ceramic layer, described alumina ceramic layer is arranged on the inside of steel plate layer ringwise.
Preferably, bondd by high polymer binder between described alumina ceramic layer and steel plate layer.
Preferably, the contact surface edge between described alumina ceramic layer is pyramidal structure.
Preferably, described alumina ceramic layer and steel plate layer inwall gap are provided with high temperature bond chamotte.
Preferably, the surface of described seamless steel pipe elbow is provided with anticorrosion layer of paint.
nullCompared with prior art，The beneficial effects of the utility model are: this utility model utilizes arch from embedding principle design，Porcelain block forms 36 ° of machineries from support structure，Use conical design，Block block interlocking between porcelain block，It is effectively guaranteed not falling off of porcelain block，The high temperature bond chamotte being resistant to 1100 DEG C is filled in porcelain block and steel plate layer inwall gap，Thus serve duplicate protection，High polymer binder is used to fix between porcelain block and steel plate layer，Elbow is made to use under the conditions of can bearing greater impact power produced by material and higher operating mode，Alumina ceramic layer uses high-purity、Ultra-fine、Particle diameter is single narrow，And the spray-dried high-quality alumina powder sending grain to process is raw material，Element idiosome makes material full densification through the temperature sintering of 1520 DEG C，Ensure that material has aplitic texture，Solve a difficult problem for deformation，This is novel have wear-resistant、Corrosion-resistant、High temperature resistant、There are higher hardness and intensity、Good resistance to mechanical impact and the advantage of thermal shock.
