Abstract
The utility model discloses a sandwich heat insulating pipeline, belonging to the technical field of the pipelines. The sandwich heat insulating pipeline of the utility model solves the abuses of a fussy technology and a nonideal heat insulating effect which are required by a traditional pipeline heat insulating mode. The sandwich heat insulating pipeline of the utility model adopts a structure mode that an inner layer, an outer layer, and a middle sandwich heat insulating layer are integrated. A pipe joint part adopts site operation to integrate the inner, the outer, and the middle layers. The sandwich heat insulating pipeline is used for conveying liquid and gas which need to be kept certain temperature.
Description
The utility model sandwich heat preservation pipeline is a kind of being used to carry the liquid of need maintenance uniform temperature and the pipe special of gas, and traditional pipe insulation mode is carried out important improvement.
Tie up thermal insulating material (as cotton, stone rock wool, foamed plastics etc.) outside the general employing of traditional pipe insulation and tie and rope brushing paint with windings such as cotton, glass fibre cloths again, perhaps the outsourcing plastic tab is easily aging.
The foaming that needs when making thermal insulation layer as conventional method with foamed polystyrene earlier polystyrene to be heated in model is tied and roped on pipeline again; technology is loaded down with trivial details; and maximum shortcoming is not have the corrosion-resistant ageing-resistant external protection of shock resistance and intermediate protective layer and internal layer body; tightly become one; therefore easily advance the sky G﹠W; so except the heat insulation effect difference, also have skin fragile, inner layer pipe body (iron pipe) easy-to-rust.Just need to change pipeline within general several years.
When oil transport pipeline adopts above-mentioned heat preserving method, with area, Qingdao winter be that example one km will reduce by five degree, thereby just have in short distance, add the station of heating for the flowability of protecting oil.
The structure of the utility model sandwich heat preservation pipeline is to adopt overall structure, and promptly internal and external layer body and middle thermal insulation layer are closely as one.
Description of drawings is as follows:
Figure (1) is the overall plan view of sandwich heat preservation pipeline of the present invention
Figure (2) is the interior outer body of a sandwich heat preservation pipeline of the present invention flange plate structure sectional view when being all glass fibre reinforced plastic material
Figure (3) is the sectional view of flange plate place insulating structure when body is iron pipe in the sandwich heat preservation pipeline of the present invention
Shown in the figure: 1, skin 2, thermal insulation layer 3, internal layer 4, flange plate
5, external protection 6, set up thermal insulation layer
Figure (1) shows: skin 1 and internal layer 3 are fiberglass (A/B component unsaturated-resin material), and heat-insulation layer 2 adopts the Polyurethane foaming, and the three becames one when making, and is mainly used in the oil transportation large diameter pipeline.
Fig. 2 shows: body 3 is become one in flange plate 4 and the outer body 1, and is solid and reliable, is mainly used in large diameter pipeline.
Figure (3) shows: flange plate 4 and interior body 3 are ironware, and available screw thread or electrogas welding connect, and external protection 5 is become one for the glass fibre reinforced plastic material scene pastes with skin 1.Thermal insulation layer 6 is in-site pouring also, is mainly used in the small-bore pipeline of transporting water and steam.
In sum: because the thermal conductivity of glass fibre reinforced plastics low (the just 1/100-1/1000 of metallic material) adds interior outer body and thermal insulation layer is become one, total coefficient of heat transfer is little, so heat insulation effect is splendid.The maximum characteristics of glass fibre reinforced plastics are the shock resistance high-and low-temperature resistances, and are corrosion-resistant, ageing-resistant, need not keep in repair.Can reduce heat station and management and maintenance personnel in a large number as oil transport pipeline.
The characteristics of the utility model sandwich heat preservation pipeline:
(1) is widely used, can be used for oil field oil transportation, mine, factory's (as chemical industry, rubber, papermaking, food etc.) needs to carry high-temperature high pressure water or the pipeline of steam and the central heat supply of civil unit, the pipeline of tap water, allly in a word needs to keep the pipeline of the oil transportation of uniform temperature, defeated vapour, water delivery all to be suitable for.
(2) manufacture technology is simple, does not need model when doing insulating foam layer and heats.
(3) fitting operation is convenient, if interior ectosome is glass fibre reinforced plastic material entirely, only needs two flange plate are connected with screw and get final product, and be iron pipe as if endosome, the then thermal insulation layer of flange plate and outer field manufacturing, execute-in-place is also very convenient.
The utility model sandwich heat preservation pipeline has following advantage compared with the prior art:
With the internal layer body, be that cast iron materials changes the corrosion-resistant ageing-resistant glass fibre reinforced plastic material of shock resistance into originally when (one) being applied to the large diameter pipeline of oil transportation.
(2) simple in structurely be convenient to fabrication and installation.
(3) be convenient to produce serial sandwich heat preservation duct products.
(4) appearance looks elegant.
(5) in light weight, shock resistance, corrosion-resistant, ageing-resistant.
(6) not fragile, be difficult for corrosion.
(7) thermal insulation property is superior.
(8) energy-saving effect is obvious.
(9) need not keep in repair substantially.
Embodiment
Size according to required internal diameter of the pipeline size, make model, paste interior conduit (if interior pipe is an iron pipe with model, then selected by size) again in the foaming of interior conduit outer wall spraying polyamine ester, foaming finishes and twine glass fibre cloth again after finishing, coat thermosetting resin, revise polishing then, promptly make a complete pipeline.
