Abstract
The utility model provides a double -walled selfreparing pipeline, effectual solved current pipeline after the use because of wearing and tearing with corrode the problem that the down easy formation of dual function was revealed, the utility model discloses an outer tube, the outer tube clear width is provided with wear resistance and anti -corrosion's inner tube, cavity intussuseption between inner tube and the outer tube is filled with basicity or fly ash acidic partially or lime stone material layer, the utility model discloses can pack the leak source voluntarily when the inner tube produces the leak source, increase pipeline life is more than 5 times of life of lining pipe way, is more than 3 times of alloy pipeline life.
Description
Technical field
This utility model relate to desulphurization system, denitrating system, wear-resistant, corrosion-resistant under the conditions of pipeline, elbow, specifically a kind of double-walled selfreparing pipeline.
Background technology
Aging and oxidation and the phenomenon that falls now in use is there will be with rubber lined pipe.Not only pipeline is resulted in blockage, and because the common pipe tubing used by rubber lined pipe easily causes leakage, to on-the-spot and environment.
Now in use cause inevitable bubble, the problem of trachoma in the middle of welding or casting because pipeline makes with alloy pipeline, after using, during due to the conveying having corrosive liquid and liquid-solid mixture under desulphurization system, denitrating system or band pressure condition, can be because, under the abrasion of conveying material and corrosion dual function, gradually forming leakage.
Utility model content
For above-mentioned situation, for overcoming the defect of prior art, this utility model provides a kind of double-walled selfreparing pipeline, effectively solves existing pipeline after a procedure because easily forming, under abrasion and corrosion dual function, the problem revealed.
This utility model includes that outer tube, described outer tube clear width are provided with the inner tube of Wear-resistant corrosion-resistant, is filled with alkalescence or the flyash of slant acidity or limestone material layer in the cavity between said inner tube and outer tube.
This utility model can fill leak source inner tube produces leak source when automatically, increases pipeline service life, is more than 5 times of lining pipeline service life, is more than 3 times of alloy pipeline service life.
Accompanying drawing explanation
Fig. 1 is this utility model main TV structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Being given by Fig. 1, the technical solution of the utility model is, including outer tube 1, described outer tube 1 clear width is provided with the inner tube 2 of Wear-resistant corrosion-resistant, is filled with alkalescence or the flyash of slant acidity or limestone material layer 3 in the cavity between said inner tube 2 and outer tube 1.
Described outer tube 1 is made up of Q235 steel.
The inner tube 2 of described Wear-resistant corrosion-resistant is made up of nichrome.
This utility model uses wear-resistant and erosion-resisting material to make inner tube 2 on material selects, and economical and practical material does outer tube 1 material.The twice laid materials such as alkalescence or the flyash of slant acidity, limestone it are full of in the middle of double-walled cavity.After inner tube 2 is worn and leak source occurs in corrosion, the reaction of dielectric fill material generates abrasion-proof corrosion-proof corrosion material, automatically fills leak source, and forms new protective layer, thus improves service life.When using in desulphurization system, use flyash or the limestone material of alkalescence, after inner tube produces leak source, owing to flyash or the limestone material of the acidic liquid in desulphurization system with alkalescence react so that it condenses, and then filling leak source, form new calcium salt quality guarantee sheath, thus improve service life, when using in the liquid of alkalescence, the flyash of slant acidity or limestone can be used as packing material, when inner tube 2 produces leak source, also generation resistant material can be reacted with akaline liquid, automatically leak source is filled, and form new calcium salt quality guarantee sheath, thus improve service life.
This utility model can fill leak source inner tube produces leak source when automatically, increases pipeline service life, is more than 5 times of lining pipeline service life, is more than 3 times of alloy pipeline service life.
