Abstract
A kind of anticorrosion composite pipe moulding pipe for steel, this anticorrosion composite pipe is by steel pipe, adhering resin, white steel sleeve, fire resistant epoxy powder anticorrosive coat is constituted, steel pipe inner wall is provided with adhering resin and white steel sleeve, white steel sleeve inwall is provided with screw thread, flange it is provided with at edges at two ends, it is provided with anticorrosive coat at outer surface of steel tube, heat-insulation layer, white steel sleeve fully combines together with adhering resin, feature is that the white steel sleeve pipe thickness used than other liner two-phase stainless steel composite steel pipe with adhering resin can reduce by 50%, non-corroding thing in steel pipe, the most i.e. ensure that water quality in pipe, enhance corrosion resistance, solve again steel pipe easily by the generation of corrosion phenomena, save expense simultaneously, extend the service life of pipeline.
Description
Technical field
This utility model relates to the anticorrosion of steel pipe, is a kind of anticorrosion composite steel tube being applicable to heat supply network, plumbing steel pipe.
Technical background
At present, existing heat supply pipeline, water supply and sewerage pipeline are used mostly steel pipe and inner liner stainless steel clad steel in laying
Pipe, but the deficiency that steel pipe exists is, uses steel pipe easily to get rusty, and corrosion thing is easily mixed in the interior water of pipe, affects the water quality in pipe and biography
Heat, easily blocks pipeline, wastes fuel, shortens the service life of pipeline, and liner two-phase stainless steel composite steel pipe words spoken by an actor from offstage steel sleeve needs
2mm is thick, and cost is high.
Summary of the invention
In order to overcome the deficiency of above-mentioned existence, the purpose of this utility model is to provide for that a kind of to mould the anticorrosion of pipe for steel multiple
Close pipe, be coated with the adhering resin set up at steel tube inner spray, white steel sleeve be embedded on the steel pipe of spraying and adhesive bonding resin, at white steel lining
Set inwall rolled thread, white steel sleeve two ends flange is welded on Steel pipe end surface, and outer surface of steel tube sprays the anticorrosive coat set up, and plays
Antiseptical effect, is easily occurred by the phenomenon of corrosion in solving steel pipe, in turn ensure that the quality of the interior water of pipe, reduces again expense simultaneously
With, extend the service life of pipeline.
This utility model solves its technical problem and be employed technical scheme comprise that, this anticorrosion composite pipe is by steel pipe, bonding
Resin, white steel sleeve, fire resistant epoxy powder anticorrosive coat are constituted, and are provided with adhering resin at steel pipe inner wall, set outside adhering resin
Having white steel sleeve, white steel sleeve outer wall and adhering resin to be bonded together, white steel sleeve inwall is provided with the screw thread of rolling, in vain
Steel sleeve combines together with adhering resin and screw thread, is provided with flange, white steel sleeve at the edges at two ends of white steel sleeve
Thickness is 0.3～0.5mm, is provided with fire resistant epoxy powder anticorrosive coat, polyurethane insulating foam layer, PE pipe skin at outer surface of steel tube
Sheath.
The beneficial effects of the utility model are, owing to have employed above-mentioned design, by spraying and adhesive bonding on steel pipe inner wall
Resin, at white steel sleeve inwall rolled thread, makes white steel sleeve fully combine together with adhering resin, and feature is that steel is moulded in pipe
Spraying and adhesive bonding resin is not have sunlight to irradiate, and uses in the case of isolation air, steel can be made to mould pipe service life and extend, in vain
Steel sleeve inwall rolled thread, makes white steel sleeve fully combine together with adhering resin, uses screw thread to enhance white steel sleeve
Intensity, compensate for steel pipe and white steel sleeve and be heated or meet the error of cold generation stroke, with adhering resin than other liner not
The white steel sleeve pipe thickness that rust steel composite steel tube uses can reduce by 50%, non-corroding thing in steel pipe, in the most i.e. ensure that pipe
Water quality, enhances corrosion resistance, solves again steel pipe easily by the generation of corrosion phenomena, saves expense simultaneously, extend pipeline
Service life.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is sectional view of the present utility model.
In figure 1, anticorrosion composite pipe, 2, steel pipe, 3, fire resistant epoxy powder anticorrosive coat, 4, inwall, 5, white steel sleeve, 6, poly-
Amine fat insulating foam layer, 7, white steel sleeve outer wall, 8, PE pipe leather sheath, 9, adhering resin, 10, flange, 11, threaded line, 12, steel
End surfaces A, 13, inwall, 14, Steel pipe end surface B.
Detailed description of the invention
Anticorrosion composite steel tube 1 is by steel pipe 2, fire resistant epoxy powder anticorrosive coat 3, white steel sleeve 5, polyurethane insulating foam layer
6, PE pipe leather sheath 8, adhering resin 9 are constituted, and are sprayed on the inwall 4 of steel pipe 2 by adhering resin 9,0.3 will made in advance
～the thick white steel sleeve 5 of 0.5mm inserts in steel pipe 2, by spiral rolling, the white steel sleeve inwall 7 of white steel sleeve 5 is rolled out spiral shell
Stricture of vagina 11, screw thread 11 is to be pressed mach by spiral roll, allows steel pipe 2, adhering resin 9 and white steel sleeve 5 merge, flange
10 are welded on Steel pipe end surface A12 and Steel pipe end surface B14, and flange 9 is the surplus warp left after white steel sleeve 5 is inserted in steel pipe 2
Flanger time processing shapes, and then the outer surface at steel pipe 2 sprays fire resistant epoxy powder anticorrosive coat 3, installs existing
PE pipe leather sheath 8, injects former polyurethane insulating foam layer 6 in PE pipe leather sheath 8, and anticorrosion composite thermal-insulating pipe completes.
