Abstract
The utility model relates an inside lining sleeve margin extroversion double layers metal conduct pipe which is inwardly provided with an inside lining sleeve of which the two terminals are provided on the end surface of the metal conduct pipe. The utility model has the advantages of simple structure, easy manufacture technique, great anti-corrosiveness, long using time and the like compared with the prior double layers metal inside lining sleeve, and is capable of transporting water, oil, gas, corrode fluid and corrode gas.
Description
The utility model belongs to the manufacturing and the welding technology field of special shape pipe, the edge section of special shape that is specifically related to double layer material manufacturing pipe and is used to carry out the work of soldering or welding.
In order to prevent the corrosion of metallic conduit; at present in metallic conduit, install the liner sleeve pipe made from resistant material additional and come the protective money metal conduit; the material of liner sleeve pipe is generally stainless steel; this double-level-metal pipeline can only use separately; connect by connecting tube with an other metallic conduit at a metallic conduit; or the end is when installing flange plate additional and connecting with the screw threads for fastening coupling; water or other corrosion liquid or etchant gas still can enter the end face of two metallic conduits; make the end face corrosion of metallic conduit, and may extend into the inwall of the crevice corrosion metallic conduit between metallic conduit and the stainless steel inner lining sleeve pipe.The pumping pipelines that uses on the oil field, adopt outer connecting tube to connect, the transfusion in chemical plant or the end of gas pipeline are connected with flange plate and connect with the screw threads for fastening coupling, and behind the end face heavy corrosion of these pipelines, corrosion liquid and etchant gas leak serious environment pollution.
The purpose of this utility model is to overcome the shortcoming of above-mentioned double-skin duct, and a kind of simple in structure, preparation process is easy, antiseptic property good, the neck bush tube edges of long service life is turned up double-level-metal pipeline is provided.
For achieving the above object, the solution that the utility model adopts is: be provided with the liner sleeve pipe in metallic conduit, the two ends of this liner sleeve pipe are arranged on the end face of metallic conduit.
The axial length of the metallic conduit that this practicality is new is less than the axial length of liner sleeve pipe.
The utility model is compared with the double-level-metal liner sleeve pipe of present use, has simple in structure, advantages such as preparation process is easy, antiseptic property good, long service life, can be used for carrying water, oil, gas, corrosion liquid, etchant gas.
Fig. 1 is an embodiment's of the utility model a structural representation.
Fig. 2 is another embodiment's of the utility model a structural representation.
Below in conjunction with drawings and Examples the utility model is further described, but the utility model is not limited to these embodiments.
In Fig. 1, the two ends outer wall of the metallic conduit 1 of present embodiment is processed with screw thread, is used for a metallic conduit 1 and an other metal tube 1 usefulness screw nipple are connected.With detonation lining or hydraulic pressure lining method liner sleeve pipe 2 is closely amplexiformed inwall at metallic conduit 1 at the inwall of metallic conduit 1, the axial length of liner sleeve pipe 2 of the present utility model is slightly larger than the axial length of metallic conduit 1, the liner sleeve pipe 2 of present embodiment adopts stainless steel material to make, liner sleeve pipe 2 linings are behind the inwall of metallic conduit 1, liner sleeve pipe 2 two ends are higher than the edge section of metallic conduit 1 both ends of the surface and outwards translate on the both ends of the surface of metallic conduit 1 with pressing, with the both ends of the surface of waterproof or other corrosion liquid or etchant gas corroding metal pipeline 1, the end outer rotating edge of liner sleeve pipe 2 connects with metallic conduit 1 both ends of the surface welded seal.
Fig. 2 has provided another embodiment's of the utility model structural representation.In Fig. 2; the metallic conduit 1 of present embodiment is the metallic conduit 1 that two ends are connected with flange plate 3; flange plate 3 is used for a metallic conduit 1 and connects by the screw threads for fastening coupling with an other metallic conduit 1; with detonation lining or hydraulic pressure lining method liner sleeve pipe 2 is closely amplexiformed inwall at metallic conduit 1 at the inwall of metallic conduit 1; the axial length of liner sleeve pipe 2 of the present utility model is slightly larger than the axial length of metallic conduit 1; the material that present embodiment liner sleeve pipe 2 adopts is identical with the preparation process that the material and the edge of first embodiment's liner sleeve pipe 2 employings turn up with the preparation process that the edges at two ends of liner sleeve pipe 2 is turned up; the edges at two ends of liner sleeve pipe 2 is turned up to the axial inward flange of flange plate; for the both ends of the surface of protective money metal conduit 1, the end outer rotating edge of liner sleeve pipe 2 connects with flange plate 3 axial inward flange welded seals.
The double-level-metal pipeline that above-mentioned two embodiments' neck bush tube edges is turned up; the both ends of the surface that make metallic conduit 1 do not contact with water or other corrosion liquid or etchant gas; protected double-level-metal pipeline end face; after having avoided the double-level-metal pipeline to be coupled to each other, water or other corrosion liquid or etchant gas leak from the connection place of double-level-metal pipeline and double-level-metal pipeline.
According to above-mentioned principle, also can design the double-level-metal pipeline that the neck bush tube edges of another concrete structure is turned up.
Claims (2)
