Embodiment Construction

[0010] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0011] A prefabricated direct-buried steam insulation pipe with high thermal insulation performance is composed of a working steel pipe 6, an insulation layer, a rolling support 4, and an outer protective steel pipe 1 in sequence from the inside to the outside. The hoop of the rolling support is on the working steel pipe, and an air layer 7 is formed between the insulation layer and the outer protecting steel pipe; the outer surfaces of the working steel pipe and the outer protecting steel pipe are all shaped with anticorrosion layers. The insulation layer is made of aluminum foil reflective cloth 2 and nano-insulation material (DR06) 3; the outer layer of the insulation layer is wrapped with glass wool and glass fiber cloth 5 to prevent the ...

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 [0001] The invention belongs to the technical field of thermal insulation pipes, in particular to a prefabricated direct-buried steam thermal insulation pipe with high thermal insulation performance. Background technique [0002] Prefabricated directly buried steam insulation pipe is a kind of steam transportation and heating equipment with a wide range of uses in the construction of houses, factories and enterprises, and plays a very important role in the long-distance transportation of high-temperature steam. However, due to structural and material reasons, the previous prefabricated direct-buried steam insulation pipes still have problems such as limited conveying distance, limited conveying temperature, and large heat consumption, which greatly increases the amount of engineering and increases the cost input. , affecting the heating efficiency of gas transmission. Contents of the invention [0003] The purpose of the present invention is to overcome th...
