Abstract
The present invention relates to a kind of wearproof composite structure pipe, 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.Wearing layer of the present invention is tamped corundum and is formed by hexagon metal hexsteel in net.Its wear-resisting property is higher tens times than common pipe.
Description
The present invention relates to a kind of conveyance conduit, particularly relate 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 invention is to provide a kind of fluid delivery tube with high-wear resistance.Be used for realizing a kind of wearproof composite structure pipe of the object of the invention, 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 invention 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.
Because having adopted, the present invention grinds off pipe in the carriage earlier, again by the wear-resistant structure of wearing layer, and because the unique texture of wearing layer, thereby making the present invention have very high wear-resisting property, it can improve tens times than general steel pipe wear-resisting property.
The present invention is described in detail below in conjunction with accompanying drawing.
Fig. 1 is the sectional view of wearproof composite structure pipe of the present invention;
Fig. 2 is the planimetric map of employed hexagon metal hexsteel among the present invention;
Fig. 3 is a corundum wearing layer oven dry plotted curve.
Referring to Fig. 1, wearproof composite structure pipe of the present invention has an inner tube 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 connection function. In the end of wearproof composite structure pipe, namely 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. Inner tube 1 preferably has one to stretch out the linkage section 5 that connects end plate 2, the end of outer tube 4 preferably be connected end plate 2 The outside is concordant.
Wearing layer of the present invention 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 invention comprises: the outer wall in an inner tube 1 coats one deck wearing layer 3, and wearing layer is fixing on inner pipe, and then wearing layer 3 usefulness one outer tube 4 is coated, and connects end plate with one between the inner and outer pipes 1,4 and connects.
The processing method of the wearing layer that adopts among the present invention 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 invention is seen Fig. 3.
When the pipe of two basic inventions 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 invention 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 invention 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 present invention 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.
Claims (3)
1, a kind of wearproof composite structure pipe is characterized in that, has in one pipe, is fixed on the wearing layer of outer wall of inner tube and coats the outer tube of said wearing layer, and 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.
2, according to the said wearproof composite structure pipe of claim 1, it is characterized in that said wearing layer 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.
