Abstract
The utility model relates to conveying pipelines for building engineering machinery, in particular to a high abrasion-resistant double-metal light type composite pipe which solves the problems of unstable quality, high cost and heavy weight caused by an unreasonable structure of an existing double-metal composite pipe. The high abrasion-resistant double-metal light type composite pipe comprises an inner pipe made of high alloy steel and an outer pipe made of low carbon steel and sleeved on the inner pipe, and the outer surface of the inner pipe is fixed with the inner surface of the outer pipe in integral welding mode. The high abrasion-resistant double-metal light type composite pipe is reasonable and reliable in structural design and cannot cause cracking in the quench process, a product is high in rigidity, service life is prolonged, energy consumption is reduced by about 50%, the weight of the composite pipe is reduced by one third compared with an existing product, and the service life is prolonged by 50% to 70%. The high abrasion-resistant double-metal light type composite pipe has the advantages of being simple in structure, convenient to process and low in cost.
Description
Technical field
The utility model relates to constructional engineering machinery and uses conveyance conduit, is specially the light-duty composite pipe of a kind of high abrasion bimetal.
Background technique
Existing composite bimetal pipe comprises two-layer: outer tube is a carbon steel tubing, mainly bears external force or interior pressure; The normal high alloy material that adopts of interior pipe is processed, and mainly plays wear-resisting effect, is interference fit between outer tube and the interior pipe.The composite bimetal pipe of this structural design makes its quenching technical be difficult to control, produces quenching hardness when high, cracks during use, easyly falls the piece phenomenon, causes product rejection; When quenching hardness hanged down, reduced working life significantly, and the short size of pipe range is wayward in the back of quenching simultaneously, causes secondary stuff-assignment.
For fear of the problem that interior pipe cracks, how to control crackle through the wall thickness of pipe in increasing, when increasing the weight of, weight increased cost.
Summary of the invention
The utility model because unreasonable structure causes unstable product quality, cost is higher and weight is heavier problem, provides a kind of high abrasion bimetal light-duty composite pipe in order to solve existing composite bimetal pipe.
The utility model is to adopt following technological scheme to realize: the light-duty composite pipe of high abrasion bimetal comprises the interior pipe processed by high alloy steel and is processed and overlapped outer tube on inner pipe by low carbon steel that inner tube outer surface is fixed with outer pipe internal surface integral solder.
In pipe adopt integral solder to fix with outer tube, overcome existing composite bimetal pipe effectively because unreasonable structure causes unstable product quality, cost is higher and weight is heavier problem.
Interior pipe is processed by the 70Mn2 steel, and outer tube is processed by the Q345B steel, and choosing through test of many times of interior pipe and outer tube material draws, and the assurance stay-in-grade while of composite pipe has further been improved the wear resistance of interior pipe and the mechanical property of outer tube.
The utility model reasonable in design is reliable; Seminess can not take place in the quenching process, product hardness is high, has prolonged working life; And energy consumption reduces about 50%; The weight ratio existing product has reduced by 1/3, has improved 50%-70% working life, has advantage simple in structure, easy to process and with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: pipe in the 1-, 2-outer tube.
