Abstract
Compound metal heat preservation outer tube is rolled the invention discloses a kind of steel/aluminium, it is characterized in overlaying the general steel sheet that the wide and thickness with aluminium alloy sheet is 0.8 ~ 1.8mm on the aluminium alloy sheet that thickness is 0.2 ~ 0.4mm, flanging, curling, seaming through tuber and roll, roll into the spiral seam thin-wall metal bushing that outer layer is aluminium alloy sheet with internal layer is that general steel sheet is complex as a whole.The present invention has good rustproof property compared with prior art, is not made of salt, Exposure to Sunlight, intensity height, good rigidity and the advantages of neat appearance, low manufacture cost, it is cost-effective, particularly for low trestle pipe network, can preferably bear to collide, extruding, the personnel of bearing are trampled without causing deformation fracture, it is ensured that and the additional heat loss that rainwater will not penetrate into heat-insulation layer and thus bring is more solid than the metal sleeve that existing aerial laying jet chimney uses, more firmly, it is harder.
Description
Technical field
The present invention relates to steam insulation Manifold technology field, especially a kind of steel/aluminium rolls compound metal heat preservation outer tube.
Background technology
The aerial laying jet chimney of prefabricated thermal insulation has obvious energy-saving effect than the jet chimney that conventional on-site is incubated, and uses
The sleeve pipe that thin metal plate machinery rolls spiral seam makees heat-net-pipeline shell and makes pipe network profile neat, rain-proof, is not afraid of Exposure to Sunlight, from
It is extremely popular with users from coming out, it is especially optimal with stainless steel sleeve pipe performance.But stainless steel is expensive, using general steel sheet or plating
Though zinc steel plate is cheap, easy corrosion, compare aluminium alloy plate relative low price, is not easy to corrosion, blemish in an otherwise perfect thing
It is aluminium sheet intensity, ratio of rigidity steel plate difference many, is easily deformed or even ruptures by hitting, extruding.
The aerial laying steam pipe system of prior art is all live heat retaining operation, and heat insulation effect is poor, and pipe network heat loss is high, pipe
Net shell is general steel sheet not corrosion resistant, easy to aging, leak out, leak, nor attractive in appearance, and stainless steel thin-wall metal bushing
Expensive although solving above mentioned problem, construction costs is high, and aluminium alloy plate antirust, price are fine, but rigidity and intensity compared with
Difference, above mentioned problem turn into the pain spot of heat supply network always.
The content of the invention
A kind of steel/aluminium that the purpose of the present invention is in view of the shortcomings of the prior art and designed is rolled outside compound metal heat preservation
Sleeve pipe, the compound spiral seam thin-wall metal bushing of steel/aluminium is made using one-time formed pipe rolling technique, set outer tube layer closes for aluminium
Golden thin plate, smooth surface, attractive in appearance, rustproof property is good, and internal layer is general steel sheet, has sufficient intensity and rigidity, the steel/aluminium
Multiple tube covers the prefabricated steam insulation pipe overcoat special for aerial laying heat supply network, and lines are neat, are not afraid of Exposure to Sunlight, will not aging,
Seaming is tight, prevents rain penetration, and low manufacture cost is cost-effective, the metallic sheath used than existing aerial laying jet chimney
Guan Yaogeng is solid, more firmly, harder.
The object of the present invention is achieved like this：A kind of steel/aluminium rolls compound metal heat preservation outer tube, including aluminium alloy
Thin plate and general steel sheet, it is characterized in stacking the general steel sheet that the wide and thickness with aluminium alloy sheet is 0.8 ~ 1.8mm
On the aluminium alloy sheet that thickness is 0.2 ~ 0.4mm, flanging, curling, seaming through tuber and roll, it is aluminium to roll into outer layer
Latten and the spiral seam thin-wall metal bushing that internal layer is general steel sheet composite integrated.
The present invention has good rustproof property compared with prior art, and Keep away from sun, anti-rain, intensity is not higher, rigidity
The advantages of more preferable and neat appearance, low manufacture cost is cost-effective, particularly for low trestle pipe network, can preferably bear to collide,
Extruding, the personnel of bearing are trampled without causing deformation fracture, it is ensured that the additional heat waste that rainwater will not penetrate into heat-insulation layer and thus bring
Lose, it is more solid than the metal sleeve that existing aerial laying jet chimney uses, it is more firmly, harder.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is Fig. 1 side view.
Embodiment
Embodiment 1
Refering to 1~accompanying drawing of accompanying drawing 2, thin-wall metal bushing 3 of the invention is by aluminium alloy sheet 1 and general steel sheet 2 through system
Pipe machine, which rolls, to be formed, and takes aluminium alloy sheet 1 and be 0.8mm's with the equal in width of aluminium alloy sheet 1 and thickness that thickness is 0.25mm
General steel sheet 2, the level of general steel sheet 2 is overlayed on aluminium alloy plate 1, is sent into the feeding mouth of special tuber, through folding
Side, curling, seaming and roll, roll into the thin-wall metal bushing 3 of aluminium/steel composite integrated and spiral seam 4.For what is rolled
The diameter of thin-wall metal bushing 3 is less, and the thickness of general steel sheet 2 can also be slightly smaller, when the casing diameter rolled is larger, steel plate 2
Thickness should be larger.
Outer layer of the present invention is aluminium alloy plate, and smooth surface, lines are neat, is not afraid of Exposure to Sunlight, will not aging, seaming is tight, can
Prevent rain penetration, not corrosion.Set inner tube layer uses general steel sheet, because steel is all significantly better than intensity, the rigidity of aluminium, and
And steel is cheaper than aluminium, therefore thicker sheet metal can be selected, there is higher cost performance, manufactured sleeve pipe steams than existing aerial laying
The metal sleeve that steam pipe road uses is more solid, more firmly, harder.
Simply the present invention is further illustrated above, and is not used to limit this patent, and all is equivalence enforcement of the present invention,
It is intended to be limited solely by within the right of this patent.
