Abstract
The invention belongs to the technical field of heat-preservation pipelines, and relates to a prefabricated buried steam heat-preservation pipe with high heat preservation performance. The pipe sequentially consists of a working steel pipe, a heat-preservation layer, a rolling bracket and an outer protective steel pipe from inside to outside, wherein the rolling bracket is hooped on the working steel pipe; an air layer is formed between the heat-preservation layer and the outer protective steel pipe; an anticorrosive layer is arranged on the outer surface of each of the working steel pipe and the outer protective steel pipe. The pipe is characterized in that the heat-preservation layer is obtained by wrapping aluminum foil reflecting cloth and a nanometer heat insulating material (DR06), and the outer surface layer of the heat-preservation layer is wrapped by glass cotton silk fiber cloth. The prefabricated buried steam heat-preservation pipe with high heat preservation performance is scientific and reasonable in structural design and higher in innovativeness, and has the advantages of low heat consumption, high conveying temperature, capability of greatly prolonging the conveying distance and lowering the manufacturing, transportation and construction cost, and the like.
Description
Technical field
The invention belongs to insulation pipe technical field, particularly the prefabricated direct-buried steam insulation pipe of a kind of high heat insulating ability.
Background technique
Prefabricated direct-buried steam insulation pipe, be during house, factory and enterprise are built purposes very widely a kind of steam carry and heating equipment, the remote conveying of high-temperature steam is played a very important role.But prefabricated direct-buried steam insulation pipe in the past, due to aspects such as structure and materials, still there is the problems such as fed distance is limited, delivery temperature is limited, heat dissipation is large, increased to a great extent engineering work load, increase cost input, affected gas transmission heating efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of heat dissipation is few, delivery temperature is high, can greatly improve fed distance, reduce the prefabricated direct-buried steam insulation pipe of high heat insulating ability of manufacture, transportation, construction cost.
The present invention solves its technical problem and is achieved through the following technical solutions:
The prefabricated direct-buried steam insulation pipe of a kind of high heat insulating ability, by working steel tube, thermal insulation layer, rolling support, external protective steel tube, formed successively from the inside to the outside, rolling support hoop is on working steel tube, between thermal insulation layer and external protective steel tube, form an air layer, described working steel tube and external protective steel tube, its outer surface is all shaped with anticorrosive coat, it is characterized in that: described thermal insulation layer, by aluminium foil reflection cloth, nano heat insulating material (DR06), wrapped and formed, thermal insulation layer external layer is wrapped up in and is covered with glass wool glass fiber cloth.
Advantage of the present invention and beneficial effect are:
The prefabricated direct-buried steam insulation pipe of the high heat insulating ability of the present invention, because thermal insulation layer adopts nano heat insulating material, its high insulating effect, heatproof is high, greatly reduce heat dissipation, improved delivery temperature, by 450 ℃, be increased to 650 ℃, improved fed distance, reduce insulation layer thickness, by original 170MM, be reduced to 30MM, thereby also reduced outer pillar diameter, having reduced link expense and the costs such as manufacture, transportation, construction, is a kind of prefabricated direct-buried steam insulation pipe of high heat insulating ability with higher innovation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1-external protective steel tube, 2-aluminium foil reflection cloth, 3-nano heat insulating material (DR06), 4-rolling support, 5-glass wool glass fiber cloth, 6-working steel tube, 7-air layer.
Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
The prefabricated direct-buried steam insulation pipe of high heat insulating ability, is comprised of working steel tube 6, thermal insulation layer, rolling support 4, external protective steel tube 1 from the inside to the outside successively.Rolling support hoop, on working steel tube, forms an air layer 7 between thermal insulation layer and external protective steel tube; Working steel tube and external protective steel tube, its outer surface is all shaped with anticorrosive coat.Thermal insulation layer, is wrapped and is formed by aluminium foil reflection cloth 2, nano heat insulating material (DR06) 3; Thermal insulation layer external layer is wrapped up in and is covered with glass wool glass fiber cloth 5, with so that thermal insulation layer is unlikely to expand splits and be tightly wrapped on working steel tube.
Working principle of the present invention is:
The prefabricated direct-buried steam insulation pipe of the high heat insulating ability of the present invention, because thermal insulation layer adopts nano heat insulating material, this heat-insulation material is that aerosil is compound in fiber, its effect of heat insulation than the superior 2-8 of traditional insulation materials doubly, the highest Applicable temperature can reach 650 degree, density 180 ㎏/m3, thermal conductivity 0.024W/ (m.K), 650 ℃ of Applicable temperatures, its Applicable temperature is much higher than 450 ℃ of the Applicable temperatures of super glass wool, its high insulating effect, the characteristic that heatproof is high, greatly reduced heat dissipation, improved delivery temperature, by 450 ℃, be increased to 650 ℃, improved fed distance, reduced insulation layer thickness, by original 170MM, be reduced to 30MM, thereby also reduced outer pillar diameter, reduced manufacture, transportation, link expense and the costs such as construction.
Although disclose for the purpose of illustration embodiments of the invention and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the present invention and claims, various replacements, variation and modification are all possible, therefore, scope of the present invention is not limited to embodiment and the disclosed content of accompanying drawing.
