Abstract
The invention discloses a composite stainless steel pipe which comprises a carbon steel pipe and a stainless steel pipe positioned on the inner wall of the carbon steel pipe. The composite stainless steel pipe is characterized in that the pipe wall of the composite stainless steel pipe is formed by spirally coiling a composite stainless steel plate; a carbon steel plate serves as the outer layer of the composite stainless steel pipe, and a stainless steel plate serves as the inner layer of the composite stainless steel pipe. Compared with the prior art, the composite stainless steel pipe has the beneficial effects that the stainless steel plate and the carbon steel plate are adhered and welded, so that the high integrity is ensured; if the pipe diameter is large and a user worries about that the stainless steel plate drops under negative pressure, the stainless steel plate can be perforated in advance, and is welded and fixedly riveted on the carbon steel pipe through holes, so that the composite stainless steel pipe is high in pressure resistance and production efficiency, large in pipe diameter and low in cost.
Description
Technical field
The present invention relates to a kind of composite steel tube and manufacture method thereof of making that Ordinary Steel is combined with stainless steel.
Background technique
Ordinary Steel is combined to the composite steel tube of making-------at the pipeline of the compound one deck corrosion resistant plate of carbon steel tube inwall with stainless steel, both media-resistant corrosion, life-span is long, can bear again high pressure, cost is also lower, of many uses, except carrying water, the conveyance conduit that can also do oil, rock gas and chemical medium, is popular.
At present, the manufacture method of stainless steel composite pipe has following several:
Blast (or undergauge) method
Thin-wall stainless steel is placed in carbon steel tube (being generally seamless steel pipe), makes Stainless Steel Tube be close to carbon steel tube inwall by explosion method; Or the diameter of carbon steel tube is shunk, reach outer and inner tube and be close to.
The shortcoming of this method is: 1., that Stainless Steel Tube is difficult for carbon steel tube " bonding " is good, a kind of " vacation is closed " often, therefore, in use, Stainless Steel Tube tends to come off.2., be difficult to make large-diameter pipeline.3., technical difficulty is large.4., cost is high.Therefore be difficult to promote.
Roll-bonding method
By rolling, thin corrosion resistant plate and carbon steel board are combined with each other, then roll into pipeline.The shortcoming of this method: " solid melting " 1., in rolling, occurs between stainless steel and carbon steel, thereby lowered the effective thickness of corrosion resistant plate.2., fund overstocks large.3. cost is higher.
Summary of the invention
The object of the invention is to overcome existing above-mentioned deficiency in prior art, a kind of stainless steel composite pipe and manufacture method thereof are provided.
In order to realize foregoing invention object, the invention provides following technological scheme:
A kind of stainless steel composite pipe, comprises carbon steel tube and is positioned at the Stainless Steel Tube on carbon steel tube inwall, it is characterized in that, the tube wall of described stainless steel composite pipe is rolled by Clad Steel Plate spiral, and described composite steel tube skin is carbon steel board, and internal layer is corrosion resistant plate.
Further, the present invention also provides following technological scheme:
A kind of stainless steel composite pipe manufacture method, comprises the following steps:
A, carbon steel board and corrosion resistant plate are pasted together to formation Clad Steel Plate;
B, Clad Steel Plate helical coil is made to steel pipe, its intermediate carbon steel sheet side outside, corrosion resistant plate is in inner side.
Preferred version of the present invention is as follows:
Preferably, in A step, punching in advance on corrosion resistant plate; By after carbon steel board and corrosion resistant plate stickup, then in the welding of the position in hole, corrosion resistant plate is welded in carbon steel board.
The auxiliary section heap of the Clad Steel Plate side that preferably, spiral rolls is welded with stainless steel.
Compared with prior art, the invention has the beneficial effects as follows: between corrosion resistant plate and carbon steel board, pass through bonding, welding, if there is good integrity----pipe diameter is very large, worry that corrosion resistant plate comes off in the time of negative pressure, corrosion resistant plate can be punched in advance, by hole, corrosion resistant plate welding, " riveting " be consolidated on carbon steel tube.Thereby the composite steel tube of making is withstand voltage height, caliber is large, and manufacturing efficiency is high, and cost is low.
Brief description of the drawings

Fig. 2 is the schematic diagram that the embodiment of the present invention is manufactured the Clad Steel Plate of pipeline.
Fig. 3 is the schematic diagram that another embodiment of the present invention is manufactured the Clad Steel Plate of pipeline.
Embodiment
Below in conjunction with test example and embodiment, the present invention is described in further detail.But this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to following embodiment, all technology realizing based on content of the present invention all belong to scope of the present invention.
Specific embodiments of the invention, a kind of stainless steel composite pipe, as shown in Figure 1, comprise carbon steel tube 1 and be positioned at the Stainless Steel Tube 2 on carbon steel tube inwall, the tube wall of described stainless steel composite pipe is rolled by Clad Steel Plate spiral, auxiliary section 3 cooperations that Clad Steel Plate rolls at spiral are welded together to form composite steel tube, and described composite steel tube skin is carbon steel board, and internal layer is corrosion resistant plate.
Process above-mentioned stainless steel composite pipe manufacture method, comprise the following steps:
A, carbon steel board 1 and corrosion resistant plate 2 are pasted together to formation Clad Steel Plate, as shown in Figure 2;
B, Clad Steel Plate helical coil is made to steel pipe, its intermediate carbon steel sheet side outside, corrosion resistant plate is in inner side.
When the caliber of needs processing is larger, depart from for fear of corrosion resistant plate and carbon steel board, can, in A step, on corrosion resistant plate, punch in advance 4, as shown in Figure 3; By after carbon steel board and corrosion resistant plate stickup, then in the welding of the position in hole, corrosion resistant plate is welded in carbon steel board.
