Abstract
The utility model discloses a wearable steel-high chromium-nickel composite pipe and comprises a pipe body. A high chromium-nickel alloy layer is cast and compounded on the interior wall of the pipe body in the vacuum condition. The pipe body is a seamless steel pipe or a hot-pressed steel board pipe. When the pipe body is an elbow, the thickness of the high chromium-nickel alloy layer compounded at the large arc section of the interior wall of the pipe body is thicker than that at the small arc section. As the high chromium-nickel alloy layer is cast and compounded on the interior wall of the pipe body in the vacuum condition, either a straight pipe, or an elbow, a variable-diameter pipe, a fork-shaped pipe, or a square and round pipe is provided with the even texture and the stable performance, and is free of cracks, air pores and other phenomena. Moreover, as the heat expansion factors of the internal layer and the external layer of the wearable composite pipe are almost the same, no crack of the internal layer and no phenomenon of early ineffectiveness will happen in the working condition of sharp changes. The internally-lined high chromium-nickel alloy layer is responsible to resist the abrasion and bears no high pressure, so as to ensure the safe operation. Thus, the utility model is in particular applicable for the long-distance delivery pipe with the high-pressure and the high-concentration.
Description
Technical field
The utility model relates to a kind of conveyance conduit, especially relates to a kind of steel-Gao chromium nickel wear-resistant composite tubes.
Background technique
In industries such as electric power, mine, metallurgy, the conveying of material, output all are to adopt closely high-pressure delivery, pipeline is bearing sizable pressure, and standing very serious wearing and tearing, the metallic conduit of single material is difficult to satisfy the requirement of this operating mode, especially elbow; Though a kind of comparatively ripe glass-ceramic tubre has higher hardness, because technological reason, the glass-ceramic tubre wall thickness is stupid, big, stupid, thick on the whole, is very restricted again in the use; At this kind situation, some manufacturers have produced the composite ceramics steel pipe, but in actual applications, ceramic layer having occurred easily comes off, lost efficacy, and when containing harmful elements such as sulphur in the material under High Temperature High Pressure, high temperature oxidation takes place easily, do not satisfy existing operating conditions.
The model utility content
The purpose of this utility model is to provide a kind of not only wear-resisting, high temperature resistant, corrosion-resistant but also steel-Gao chromium nickel wear-resistant composite tubes with higher mechanical strength and shock resistance.
For achieving the above object, the utility model can be taked following technical proposals:
Steel described in the utility model-Gao chromium nickel wear-resistant composite tubes comprises body, and suction pouring is compounded with the high-chromium-nickel alloy layer on the inwall of described body.
Described body is seamless steel pipe or steel plate hot pressing pipe.
The described thickness difference that is compounded in the high-chromium-nickel alloy layer of inboard wall of tube body both sides.
Advantage of the present utility model is that suction pouring is compounded with the high-chromium-nickel alloy layer on the inwall of described body, no matter be straight tube, bend pipe, reducer pipe or breeches pipe, circumference pipe, all even tissue, stable performances, phenomenons such as crackle, pore can not appear, and because the inside and outside layer thermal expansion coefficient of this wear-resistant composite tubes is suitable, for operating mode occasion highly jumpy is arranged, internal layer can not appear with splitting, the phenomenon of early failue takes place; The outer wall of this product is a steel pipe, mainly bear high pressure, and the high-chromium-nickel alloy layer of liner only is responsible for the opposing abrasive wear, need not bear high pressure, so more can guarantee safe operation, be specially adapted to high pressure, high concentration, the remote pipeline of carrying, simultaneously owing to be that two kinds of metals are mutually compound, possesses weldability again with A3,16Mn steel, make integrated piping safe and reliable, resistance performance height can arbitrarily knock when local plugging takes place the pipeline water conservancy diversion, cut, unload change, install, overhaul very convenient.At the difference of its use occasion, outer field steel pipe can adopt seamless steel pipe or by quality steel plate through hot pressing, pick the steel pipe that forms; When body is bend pipe (elbow), because the impact force that the inwall at orthodrome place bears during operation is big, be serious wear,, can prolong the working life of whole pipe like this so be compounded in the thickness that the thickness of the high-chromium-nickel alloy layer at inboard wall of tube body orthodrome place is greater than roundlet arc place.
Description of drawings
Fig. 1 is the structural representation of the utility model bend pipe.
Fig. 2 is the structural representation of the utility model straight tube.
Embodiment
As shown in Figure 1, steel described in the utility model-Gao chromium nickel wear-resistant composite tubes (elbow), comprise body 1, suction pouring is compounded with high-chromium-nickel alloy layer 2 on the inwall of described body 1, wherein is greater than the thickness at roundlet arc place at the thickness of the high-chromium-nickel alloy layer 2 at inboard wall of tube body orthodrome place.
As shown in Figure 2, steel described in the utility model-Gao chromium nickel wear-resistant composite tubes (straight tube) comprises body 1, and suction pouring is compounded with the high-chromium-nickel alloy layer 2 of uniform thickness on the inwall of described body 1.
Claims (3)
1. steel-Gao chromium nickel wear-resistant composite tubes comprises body (1), and it is characterized in that: suction pouring is compounded with high-chromium-nickel alloy layer (2) on the inwall of described body (1).
2. steel according to claim 1-Gao chromium nickel wear-resistant composite tubes is characterized in that: described body (1) is seamless steel pipe or steel plate hot pressing pipe.
3. steel according to claim 1-Gao chromium nickel wear-resistant composite tubes is characterized in that: the described thickness difference that is compounded in the high-chromium-nickel alloy layer (2) of body (1) inwall both sides.
