Abstract
The invention provides a novel pipeline system which comprises a working steel pipe; an inner anti-corrosion layer, a damping layer, an inorganic heat insulation layer, a fastening tape, a reflection layer, an organic heat insulation layer and a glass steel outer protection pipe are sequentially arranged on the outer side of the working steel pipe; and the fastening tape binds the inorganic heat insulation layer. The novel pipeline system has the beneficial effects of simple structure, lower price, no corrosion problem and the like.
Description
Technical field
The invention belongs to the heat supply pipeline apparatus field, especially relate to a kind of novel pipeline system.
Background technique
Direct-buried steam pipe is the same with the hot water pipeline direct-burried, has many-sided society and economic advantages with trench with making somebody a mere figurehead to lay to compare.As take up an area of less, do not influence look of the city and urban planning.Engineering cost is low, low, the long service life of heat loss, and maintenance cost is low etc.In recent years, China clearly advocates and requires municipal heating systems design " steam line is walked underground ", forbids that steam line is built on stilts to lay.If pipe laying chlorion, sulphion equal size than soil with high (especially in the coastal area) in the time, bigger to existing Corrosion of Pipeline property, reduce working life of pipeline.
Summary of the invention
The problem that the present invention will solve provides a kind of novel pipeline system, has especially solved corrosion problems, and cost is lower simultaneously.
For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: a kind of novel pipeline system; Comprise working steel tube; Be provided with interior anticorrosive coat, drag reduction layer, inorganic insulating layer, restraint zone, reflecting layer, organic heat-insulating layer and external glass fibre reinforced plastics pipe successively in the said working steel tube outside, said restraint zone bundlees inorganic insulating layer.
Further, said inorganic insulating layer is hydrophobic composition silicate thermal insulation layer or alumina silicate thermal insulation layer or centrifugally glass-wool thermal insulation layer.
Further, said organic heat-insulating layer is a polyurethane insulation coating.
Further, said restraint zone is a Stainless Steel Band.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, make the present invention have simple in structure, cost is lower, do not have advantage such as corrosion problems.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is the partial enlarged drawing at A of the present invention position
Among the figure:
1, working steel tube 2, interior anticorrosive coat 3, drag reduction layer
4, inorganic insulating layer 5, restraint zone 6, reflecting layer
7, organic heat-insulating layer 8, external glass fibre reinforced plastics pipe
Embodiment
Like Fig. 1, shown in 2; Working steel tube 1 of the present invention; Anticorrosive coat 2, drag reduction layer 3, inorganic insulating layer 4, restraint zone 5, reflecting layer 6, organic heat-insulating layer 7 and external glass fibre reinforced plastics pipe 8 in said working steel tube 1 outside is provided with successively; 5 pairs of inorganic insulating layers 4 of said restraint zone bundle; Restraint zone 5 is a Stainless Steel Band, and inorganic insulating layer 4 can be selected hydrophobic composition silicate thermal insulation layer or alumina silicate thermal insulation layer or centrifugally glass-wool thermal insulation layer for use, characteristics such as the hydrophobic composition silicate thermal insulation layer has the heatproof height, thermal conductivity is higher, density is big, cost is higher, water boiling resistance property difference; Not flammable, characteristics such as heatproof is high, cost is moderate, density is big, water boiling resistance property difference that the alumina silicate thermal insulation layer has; The centrifugally glass-wool thermal insulation layer has characteristics such as heatproof is moderate, thermal conductivity is low, cost is moderate, water boiling resistance property is good; In the use, can choose suitable material according to Environmental Conditions and construction budget; Organic heat-insulating layer 7 is a polyurethane insulation coating, has high insulating effect, the characteristics that hull-skin temperature is lower; There is not etching problem in external glass fibre reinforced plastics pipe 8, and cost is also lower.
The working procedure of this instance: if external glass fibre reinforced plastics pipe 8 soaks in working process; Can influence the intensity and the life-span of glass fibre reinforced plastics; Therefore external glass fibre reinforced plastics pipe 8 will be taked perfect rainproof, drainage measure in making and site operation, because there is not corrosion problems in glass fibre reinforced plastics, cost is lower; Therefore be suitable for chlorion, sulphion equal size than in the soil with high, solved existing pipeline corrosive requirement.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
