Abstract
The utility model relates to a high wear-resistant conveying bend pipe, which comprises a pipe body and is characterized in that a high wear-resistant alloy-steel pipe layer is arranged on the inner wall of the pipe body and inner flanges are arranged and connected with two ends of the pipe body. The bend pipe is the 90-degree bend pipe, a common metal pipe layer is arranged outside the high wear-resistant alloy-steel pipe layer, and the common metal pipe layer and the high wear-resistant alloy-steel pipe layer are close combined. The high wear-resistant conveying bend pipe adopts the double layer physical design to cause the inner wall thereof to have higher wear-resisting property, the amount of the expensive high wear-resistant alloy-steel is also saved at the same time, the manufacturing cost is low, the service life is long, and the wear-resisting property of the abutting-joint part is better. The high wear-resistant conveying bend pipe can be used in the conveying operations of various solidoid materials or the conveying operations containing the solidoid materials.
Description
Technical field
The utility model belongs to the conveying equipment technical field, is specifically related to be applied in a kind of high abrasion transporting elbow of materials such as sandstone, coal, concrete.
Background technique
Carrying as higher abrasion-proof pipes of solid content such as coal ash, coal, ore in sand form, sandstone, because of the conveyance fluid high-speed motion, scouring force to inner tube wall is bigger, wearing and tearing are easy to impact, when especially carrying solid phase hard ware material fluid, the scouring force that conveying pipeline inner wall bears is very huge, causes the tube wall attenuation and damaged ineffective.At present for improving wear-resistant degree, adopt single common steel tube to improve wear-resistant degree more, because the rub proofness of common iron is lower, simultaneously exist docking point to cause this docking site at first to be worn through easily, can't satisfy conveyance conduit low cost, long-life using effect in the docking site of two steel pipes.And be that the cost of highly wear-resisting alloy steel and non-manganese highly wear-resisting alloy steel is higher as rare earth, can't be used in the making of whole steel pipe.
The model utility content
The purpose of this utility model is to provide a kind of fabricating cost low, long service life, and the preferable high abrasion transporting elbow of the wear-resisting property of docking site, and it can solve, and existing solid material conveying pipe road wear-resisting property is poor, the docking site defective of easy wearing and tearing.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of high abrasion transporting elbow comprises body, it is characterized in that the inwall of described body is provided with high-wear-resistant alloy steel pipe layer, and the two ends of body are provided with the connection inner flange.
Concretely, described bend pipe is 90 degree bend pipes, the outer installment common metal pipe layer of high-wear-resistant alloy steel pipe layer, and described common metal pipe layer and high abrasion metal tube interlayer are combined closely.
The inwall of described inner flange is provided with the highly wear-resisting alloy steel layer, described highly wear-resisting alloy steel layer and the closed butt joint of high-wear-resistant alloy steel pipe layer.
The thickness of the abrasion resistance alloy steel pipe layer of the outside bow portion of described body is greater than the thickness of other position abrasion resistance alloy steel pipe layer.
Change double layer design by tube wall into by individual layer, can reduce the expensive of whole employing highly wear-resisting alloy steels on the one hand, can improve the wear-resisting property of conveying pipeline inner wall on the other hand this high abrasion transporting elbow.Connection orchid in being provided with by two ends in addition at bend pipe, and with the blue high-wear-resistant alloy steel that adopts of interior connection, the position of all contact conveying material all has high-wear resistance.The switching performance of interior connection orchid is superior, and the seam of its docking site is very tight, has prevented the high wear of conveying material to this position preferably.The highly wear-resisting alloy steel layer that thickening is set in the bend pipe outside bow portion that is subjected to scouring force maximum, the easiest wearing and tearing can improve the wear-resistant life-span at position easy to wear.
The beneficial effects of the utility model are that this high abrasion transporting elbow adopts the double layer construction design, makes its inwall possess higher wear-resisting property, saved simultaneously the consumption of expensive highly wear-resisting alloy steel again, fabricating cost is low, long service life, and the wear-resisting property of docking site is preferable.This high abrasion transporting elbow can be used for various solid-phase materials or contains the conveying operation of solid-phase material.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model embodiment.
Embodiment
