Abstract
The utility model relates to a composite seamless steel tube for a heat exchanger. The composite seamless steel tube comprises a carbon steel seamless steel tube base body, wherein a layer of titanium alloy pipe is attached to the inner surface of the carbon steel seamless steel tube base body, and an aluminum layer is composited on the outer surface of the carbon steel seamless steel tube base body and provided with a plurality of protruding aluminum radiating ribs which extend in the length direction of the seamless steel tube base body and rotate around the axis of the seamless steel tube base body. The composite seamless steel tube has the advantages that the titanium alloy pipe is composited on the inner wall of the composite seamless steel tube, so that corrosion resistance is improved; compared with the existing titanium alloy pipe, usage cost is reduced, and market vacancy is filled. By means of the aluminum layer composited outside the seamless steel tube, corrosion resistance of the outer wall of the carbon steel tube is ensured, the radiating ribs can be drawn out of the aluminum layer conveniently, heat exchange performance of a heat exchange tube is improved, and pressure resistance of the heat exchanger can be strengthened by means of the radiating ribs.
Description
Technical field
The utility model relates to a kind of heat exchanger composite seamless steel pipe.
Background technology
Existing seam-less carbon steel pipe reasonable price, be widely used, but to the poor corrosion resistance of chloride, sulfide and ammonia, and in oil, chemical field, the medium passing through in steamless steel pipe for heat exchanger usually contains the material of these perishable steel pipes, make to need often to change these heat exchanger tubes, indirectly improved use cost.
Utility model content
Technical problem to be solved in the utility model is: a kind of heat exchanger composite seamless steel pipe is provided, in improving the service life of steel pipe, improves heat exchange efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat exchanger composite seamless steel pipe, comprise carbon steel seamless steel pipe matrix, at the inner surface additional last layer titanium alloy tube of carbon steel seamless steel pipe matrix, in the outer surface composite layer of aluminum of carbon steel seamless steel pipe matrix, on aluminium lamination, have the aluminium heat radiation rib of many protrusions, many aluminium heat radiation ribs extend and rotate around seamless steel pipe matrix axis along the length direction of seamless steel pipe matrix.
For improving the combination reliability between aluminium lamination and carbon steel tubing, avoid layering, the outer surface of carbon steel seamless steel pipe matrix has zinc layer, and aluminium lamination is wrapped in outside zinc layer.Zinc layer plays transitional function between carbon steel and aluminium lamination.
The beneficial effects of the utility model are: this composite seamless steel pipe is at the inwall composite titanium compo pipe of steel pipe, improve decay resistance, and reduce use cost with respect to existing titanium alloy tube, the market vacancy of having substituted, outside seamless steel pipe, compound aluminium lamination had both ensured the decay resistance of carbon steel tubing outer wall, be convenient to again draw out heat radiation rib on aluminium lamination, improve the heat exchange property of heat exchanger tube, heat radiation rib can also be strengthened the withstand voltage properties of heat exchanger simultaneously.
Brief description of the drawings
Fig. 1 structural representation of the present utility model;
In figure: 1. carbon steel seamless steel pipe matrix, 2. titanium alloy tube, 3. aluminium lamination, 31. aluminium heat radiation rib, 4. zinc layers.
Detailed description of the invention
As shown in Figure 1, a kind of heat exchanger composite seamless steel pipe, comprise carbon steel seamless steel pipe matrix 1, at the inner surface additional last layer thin-wall titanium alloy pipe 2 of carbon steel seamless steel pipe matrix 1, in the outer surface composite layer of aluminum 3 of carbon steel seamless steel pipe matrix 1, on aluminium lamination 3, have the aluminium heat radiation rib 31 of many protrusions, many aluminium heat radiation ribs 31 extend and rotate around seamless steel pipe matrix 1 axis along the length direction of seamless steel pipe matrix 1.The material of aluminium lamination can be that allumen can be also other aluminium alloys, and also not getting rid of is fine aluminium.
Thin-wall titanium alloy pipe 2 and carbon steel seamless steel pipe matrix 1 carry out certain cleaning and grinding process before rolling, are integrated by the method rolling of rolling, after rolling, heat-treat, and ensure both effective combinations.
The outer surface of carbon steel seamless steel pipe matrix 1 has zinc layer 4, and aluminium lamination 3 is wrapped in outside zinc layer 4.Zinc layer is wrapped in the outer surface of carbon steel seamless steel pipe matrix 1 by the mode of electroplating.
