Description
Technical field
The present invention relates to a kind of heat-insulating pipeline, particularly relate to a kind of resistance to 500 DEG C of ultra-thin heat-insulating pipelines.
Background technique
Pipeline is the common tool be applied in transport, and it has played important function in transport Oil, Water, Gas etc.But when transporting these products, especially oil, rock gas, liquid gas etc., for the delivering pipe be exposed in air, sunshade thermal insulation is very important, deals with improperly and very easily causes " gas blocks up ", bring very burden to pipe-line maintenance.Especially during the broiling summer, or broadly say, in the tropical and subtropical zone area of lasting sweltering heat, then even more important.
Traditional heat insulation processing mode is usually twine at pipe surface tie up thermal-protective material or smear adiabatic gum, to reaching heat insulation sun, the stable effect transmitted.But these modes still can not meet the demands, be wound around the thermal insulating materials such as conventional urethane and there is the shortcomings such as thickness is large, cost is high, poor thermal insulation property, easily corrosion and ageing, inconvenience often changes thermal-protective material again, there is very large potential safety hazard.Smear adiabatic gum thermal insulation property more limited, also there is the problem that other is same.
In view of the foregoing, need to provide a kind of heat-insulating pipeline of durable, good heat-insulation effect urgently.
Application number be 201410637063.8 Chinese invention patent disclose porous nanometer material heat-insulating pipeline structure, comprise steelwork pipe and porous nanometer material thermal insulation layer.Porous nanometer material is wrapped in outside steelwork pipe as thermal insulation layer.This device is logical introduces porous nanometer material more, utilizes the characteristics such as its good heat insulation, water-fast, heatproof, high strength, improves efficiency of thermal transfer and the serviceability of pipeline, reduction energy loss.
Authorization Notice No. is that the Chinese model utility of CN202048309U discloses a kind of heat-insulating pipeline, and it comprises basic unit and is arranged on the solar heat reflection layer in described basic unit, and described solar heat reflection layer is formed by solar heat reflection composition and polymer.Wherein this solar heat reflection layer can usable reflection sun heat radiation, and therefore, this model utility can alleviate the temperature that pipeline produces because of sunlight and raise, and guarantees that pipeline stabilization normally works, extends the working life of pipeline.
Vacuum heat-insulating plate is the one of heat insulating material; it is based on vacuum insulation principle; by improving degree of vacuum in plate to greatest extent and filling porous low thermal conductivity material and realize thermal insulation; from its structure; be composited by the good filling core of heat-shielding performance and barrier film; compound tense; first using barrier film as the coated porous filling core in protection top layer; make protection top layer by decompression vacuum pumping and fill core again to fit tightly, finally heat-sealing sealing is carried out to protection surface layer film.At compound tense, the heat trnasfer that decompression vacuum pumping process makes vacuum heat-insulating plate effectively to avoid cross-ventilation to cause, its thermal conductivity significantly reduces, so on the basis of identical thermal requirements, vacuum heat-insulating plate can effectively reduce the thickness of thermal shield than common thermal shield, vacuum heat-insulating plate is made to have volume little, lightweight advantage, at present, to have mass area ratio light because of it for vacuum heat-insulating plate, easy construction, nontoxic, pollution-free, environmental protection, long service life, the advantage such as nonflammable and be widely used in aviation aircraft, aircraft carrier, naval vessel, submarine, wind-tunnel, freezer, shipping container, refrigerator, high ferro, automobile, multiple energy-saving field such as building.
But existing vacuum heat-insulating plate has high requirement to Environmental Conditions, the serviceability temperature of different film material is different, and aluminum plastic film vacuum heat-insulating plate using effect is at low temperatures better, but will decomposition failure under high temperature; Although the vacuum heat-insulating plate of stainless steel membrane material can realize application in high temperature environments, heat bridge effect is large, also only has flat at present.
Summary of the invention
The object of the invention is to overcome existing heat-insulating pipeline heaviness, soak poor performance and aging problem, a kind of resistance to 500 DEG C of ultra-thin heat-insulating pipelines are provided.
For realizing object of the present invention, the technological scheme adopted is: a kind of resistance to 500 DEG C of ultra-thin heat-insulating pipelines, comprise stainless steel structure pipeline, glass fibre cotton felt and stainless steel membrane three part, it is characterized in that forming vacuum environment by laser bonding between described stainless steel membrane and stainless steel structure pipeline, glass fibre cotton felt is closely wound around stainless steel structure pipeline wherein.The wall thickness of described stainless steel structure pipeline is 1 ~ 3mm, and the thickness of described stainless steel membrane is 15 ~ 200 μm, and the insulation layer thickness that glass fibre cotton felt and stainless steel membrane are formed is 1.5 ~ 2.5mm.
The beneficial effect that the present invention has is: the restriction 1. breaking through traditional vacuum thermal insulating material, can temperature 500 DEG C in resistance to pipe; 2. structure realizes ultrathin; 3. there is good heat insulation, water-fast, heatproof, high strength, anti-aging characteristic, increased substantially efficiency of thermal transfer and the serviceability of pipeline, greatly reduced energy loss.(4) gas of hot fluid, heat can be led in pipeline.
