Abstract
The utility model relates to a wear-resistant composite structure tube, which is characterized in that the wear-resistant composite structure tube has an inner tube, a wear-resistant layer fixed on the outer wall of the inner tube and an outer tube coating the wear-resistant layer. A connecting end plate for sealing and plugging the wear-resistant layer and connecting the inner and the outer tubes is arranged between the end portions of the inner and the outer tubes. The wear-resistant layer of the utility model is formed by hexagonal metal turtleback nets and corundum solidly filled in the nets. The wear-resistant performance of the wear-resistant composite structure tube is higher scores of times than that of an ordinary pipeline.
Description
The utility model relates to a kind of conveyance conduit, particularly relates to a kind of abrasion-proof pipe of composite structure.
Existing wear resistant conveying pipe generally is a carbide steel, coated with hard alloy pipe, heat treatment carburizing pipe etc.Though these pipelines have certain wear-resisting property, they still can not satisfy the FLUID TRANSPORTATION that contains the granule hard ware material, particularly are not suitable for the conveying of the fluid that contains the granule hard ware material of high temperature, high flow rate.
The purpose of this utility model provides a kind of fluid delivery tube with high-wear resistance.
Be used for realizing a kind of wearproof composite structure pipe of the utility model purpose, it is characterized in that, have in one pipe, be fixed on the wearing layer of outer wall of inner tube and coat the outer tube of said wearing layer, one of welding is used for shutoff wearing layer and connect the connection end plate of inner and outer pipes between the end of inner and outer pipes.Interior pipe wherein only plays the carriage effect, and very behind the quick-wearing, wearing layer begins to work at it.
Wearing layer of the present utility model comprises that is fixed on a corundum that stirs with aluminium hydroxide of filling in hexagon metal hexsteel on the outer wall of inner tube and each hexagonal space on said hexsteel.
Grind off pipe in the carriage earlier because the utility model has adopted, again by the wear-resistant structure of wearing layer, and because the unique texture of wearing layer, thereby make and the utlity model has very high wear-resisting property, it can improve tens times than general steel pipe wear-resisting property.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the sectional view of wearproof composite structure pipe of the present utility model;
Fig. 2 is the planimetric map of employed hexagon metal hexsteel in the utility model;
Fig. 3 is a corundum wearing layer oven dry plotted curve.
Referring to Fig. 1, wearproof composite structure pipe of the present utility model has in one manages 1, is fixed on the wearing layer 3 of outer wall of inner tube and the outer tube 4 of coating wearing layer, and the effect of outer tube 4 mainly is that the protection wearing layer has reached interconnect function.In the end of wearproof composite structure pipe, promptly one of welding is used for shutoff wearing layer and connect the connection end plate 2 of inner and outer pipes between inner and outer pipes.Interior pipe 1 preferably has one to stretch out the linkage section 5 that connects end plate 2, and the end of outer tube 4 is preferably concordant with the outside that is connected end plate 2.
Wearing layer of the present utility model comprises that a hexagon metal hexsteel 6(who is fixed on the outer wall of inner tube sees Fig. 2) and the corundum 7 that stirs with aluminium hydroxide of in each hexagonal space of hexsteel, filling.
The manufacture method of wearproof composite structure pipe of the present utility model comprises: in one, coat one deck wearing layer 3 on the outer wall of pipe 1, and wearing layer is fixing on inner pipe, and then with 4 coatings of wearing layer 3 usefulness one outer tube, connect end plate with one between the inner and outer pipes 1,4 and connect.
The processing method of the wearing layer that adopts in the utility model is:
Put a hexagon metal hexsteel on the outer wall of interior pipe, hexsteel and inner tube outer surface adopt the point type welding;
Use the corundum that stirs by aluminium hydroxide to fill and tamping in each hexagonal space on said hexsteel;
On outer tube, open an exhaust port, so that discharge the moisture when drying;
Will be by the hexagon metal hexsteel of inner and outer pipes clamping and the corundum oven dry of in the hexagonal space of hexsteel, tamping;
The exhaust port that shutoff is offered on outer tube.
Oven dry curve of the present utility model is seen Fig. 3.
When the pipe of two basic model utilitys docks, the linkage section 5 of pipe 1 in should welding earlier, whole weld bond is answered full weld, and does ultrasonic examination.Complete hexsteel 6 at joint then, added corundum more as stated above, add outer tube 4 again after interior pipe and corundum wearing layer are all prefabricated.
Wearproof composite structure pipe of the present utility model is applicable to that mine, metallurgy industry etc. contain the FLUID TRANSPORTATION of small particles material, are more suitable for the FLUID TRANSPORTATION of catalyzer in the petrochemical industry course of working.Lift an example below effect of the present utility model is described.
There are a flue gas and catalyst transport in The Refinery Daqing Petrochemical Plant, and the former design material of this pipeline is Cr5Mo, 550 meters of flue gas flows
3In/time, it is higher to contain the catalyst solid granule density in the flue gas, is 6.6 kilograms/meter
3Temperature is 680 ℃, flow velocity is 380 meter per seconds, this pipeline comes into operation, and not only pipeline was worn out in three months, and the valve on the pipeline (carbon steel), valve body also leak (this position of national petrochemical system all exists and still is not resolved at present) by mill, and in 1986 this pipeline has adopted the wear-resistant structural tube of the utility model to use so far and still used continuing in 6 years.When shut-down (breakdown) mainteance this pipeline part severed with bubble in 9 years and check that abrasion-proof structure pipeline internal surface has the uniform wear of 3.5～4.5mm, this abrasion-proof structure tube thickness also is 20mm, by realizing using wearing and tearing thickness to calculate, can also use 10 years.This shows that terminal life can reach 16 years, is more than 60 times of Cr5Mo pipe working life.
