Large caliber bend can not be made of the method for welding and pushing, and weld ell and push-making angle fitting are difficult to meet present pipe design pair
Discharge head requirement.
A kind of high pressure heavy wall large-calibre seamless hot-pressed elbow is disclosed in the prior art（The patent No.
CN201120579907.X）Solve above mentioned problem.But the pipeline of this elbow composition of the prior art is in elbow interior wall
Place causes larger impact because current change direction meeting elbow interior wall, under the influence of impact, is easily rushed at the inwall of elbow
Brush corrosion, have impact on the service life of elbow.
The content of the invention
The present invention goal of the invention be：For it is of the prior art " elbow composition pipeline at elbow interior wall due to
Current change direction meeting elbow interior wall and cause larger impact, and under the influence of impact, corrosion is easily washed at the inwall of elbow,
Have impact on the service life of elbow " the problem of there is provided a kind of wear-resisting alloy composite elbow.
In order to solve the above technical problems, the present invention is adopted the technical scheme that, a kind of wear-resisting alloy composite elbow, including
Bending section (1), straight length (2), elbow body are weldless hot-pressed elbow；The bending section（1）Rubber is provided with inwall
Adhesive linkage（4）, bonding rubber layer（4）Inner surface on be provided with potsherd laminating layer（5）, bending section（1）, bonding rubber layer
（4）, potsherd laminating layer（5）It is molded by heating bonding by Vulcanization.
Optimization, above-mentioned wear-resisting alloy composite elbow, the potsherd laminating layer（5）There are some potsherds to splice and
Into.
Optimization, above-mentioned wear-resisting alloy composite elbow, the potsherd is square, and potsherd is neatly arranged by ranks.
Optimization, above-mentioned wear-resisting alloy composite elbow, the bending section（1）With bonding rubber layer（4）Between have gluing
Agent, bending section（1）The bonding that some arcs are provided with inwall is raised（11）.
Optimization, above-mentioned wear-resisting alloy composite elbow, the elbow outer diameter D is that 610~1220mm, wall thickness (3) are 30
~150mm, the radius of curvature R of bending section (1) and elbow diameter D relation are：1.0D≤R≤1.5D, the straight length (2)
A1, a2 length is between 0~100mm, angle of bend θ are 10 °≤θ≤90 °.
Optimization, above-mentioned wear-resisting alloy composite elbow, the elbow be by material trademark be 20,20G, A106B,
A106C、WPB、WPC、St35.8、St45.8、15CrMoG、12Cr1MoVG、10CrMo910、10Cr9Mo1VNb、
15NiCuMoNb5, P11, P12, P91, P92, WB36 seamless steel pipe are fabricated by for raw material.
The advantage of the invention is that the drawbacks of it can overcome prior art, reasonable in design is novel.The technology of the application
In scheme, in bending section（1）Pass through bonding rubber layer on inwall（4）It has been bonded potsherd laminating layer（5）, add bending section
（1）The wearability of inwall, due to ceramics wearability it is good, impacted for a long time even at current under, also will not be excessive
Abrasion, adds the service life of elbow.
