Description

A kind of wear-resistant and corrosion-resistant corundum pipe elbow
Technical field
It is specially a kind of wear-resistant and corrosion-resistant the present invention relates to wear-resistant and corrosion-resistant corundum pipe elbow technical field Corundum pipe elbow.
Background technology
With China's rapid development of economy, pipeline throughout industries such as electric power, metallurgy, petrochemical industry, coals, works as pipeline During the big material of the grindabilities such as Nei Shu roads lime-ash, coal dust, tantalite power, the problem of pipe wear is fast, particularly bend pipe are all there is Abrasion faster, when conveying the gas, liquid or solid of strong corrosion in pipeline, has pipeline and is corroded and damages The problem of, when conveying has the material of higher temperature in pipeline, exist and use the problem of heat resisting pipe is expensive.Therefore Country be badly in need of at present it is a kind of can be with high-temperature corrosion resistance, high temperature resistant corrode and wear-resistant pipeline, particularly for connecting pipe Elbow, performance is more preferable than straight pipeline could to realize these functions, increase pipeline service life.
The content of the invention
It is an object of the invention to provide a kind of wear-resistant and corrosion-resistant corundum pipe elbow, to solve above-mentioned background technology The pipe elbow of middle proposition is intolerant to corrosion, wear is fast and the problem of fast high temperature corrode.
To achieve the above object, the present invention provides following technical scheme：A kind of wear-resistant and corrosion-resistant corundum pipe elbow, Including ceramic composite steel pipe end face of elbow, the ceramic composite steel pipe end face of elbow is provided with nut connector, and Ceramic Composite Steel elbow end face is arranged on the two ends of seamless steel pipe elbow, and the surface of the seamless steel pipe elbow is provided with reinforcement, the nothing Seam steel elbow is made up of corundum layer, alumina ceramic layer and steel plate layer, and corundum layer is arranged on the inside of alumina ceramic layer Surface, the alumina ceramic layer is arranged on the inside of steel plate layer in a ring.
It is preferred that, bonded between the alumina ceramic layer and steel plate layer by high polymer binder.
It is preferred that, the contact marginal surface between the alumina ceramic layer is pyramidal structure.
It is preferred that, the alumina ceramic layer is provided with high temperature bond chamotte with steel plate layer inwall gap.
It is preferred that, the surface of the seamless steel pipe elbow is provided with anti-corrosion layer of paint.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is using arch from embedding principle design, and porcelain block is formed 36 ° of machineries are from support structure, using conical design, and block block is interlocked between porcelain block, is effectively guaranteed not falling off for porcelain block, porcelain block and steel The filling of flaggy inwall gap is resistant to 1100 DEG C of high temperature bond chamotte, so that duplicate protection is served, between porcelain block and steel plate layer Fixed using high polymer binder, make elbow to bear to use under the conditions of greater impact power and higher operating mode produced by material, Alumina ceramic layer is single narrow using high-purity, ultra-fine, particle diameter, and the spray-dried high-quality alumina powder for sending grain to handle For raw material, plain idiosome makes material full densification by 1520 DEG C of temperature sintering, it is ensured that material has aplitic texture, solves The problem of deformation, this it is new with wear-resistant, corrosion-resistant, high temperature resistant, have higher hardness and intensity, good resistance to mechanical impact With the advantage of thermal shock.
