Abstract
The utility model discloses a kind of steam long-distance sand transport low-loss direct-burried insulation construction, is made up of working steel tube, aeroge heat-insulation layer, fiber aluminium foil reflecting layer, super glass wool heat-insulation layer, air layer, steel outer casing, RPUF heat-insulation layer and high density polyethylene (HDPE) trocar sheath from inside to outside successively.This utility model adopts the less aeroge of heat conductivity and RPUF heat-insulation layer, can effectively reduce insulation layer thickness, so as to reduce steel outer casing size, reduces construction costs；The version of RPUF heat-insulation layer and high density polyethylene (HDPE) trocar sheath is adopted outside steel outer casing; when high density polyethylene (HDPE) trocar sheath is destroyed; RPUF heat-insulation layer can also isolate soil and water; protect steel outer casing not corroded, extend the direct-buried steam pipeline life-span.
Description
Technical field
This utility model belongs to jet chimney technical field, relates in particular to a kind of steam long-distance sand transport low-loss
Direct-burried insulation construction.
Background technology
Generally direct buried steam pipe with steel jacket adopts the single insulation construction of super glass wool, and the insulation of single insulation construction is thick
Degree is thicker to cause steel outer casing size larger, so as to cause construction costs higher；Generally steel is protected outside direct buried steam pipe with steel jacket
Pipe adopts epoxide coal bituminous or 3PE anticorrosive coats, after there is local anti-corrosion damage layer, steel outer casing can be caused to corrode.
The content of the invention
The purpose of this utility model is to overcome shortcoming of the prior art, there is provided a kind of steam long-distance sand transport is with low
Heat waste direct-burried insulation construction.
For achieving the above object, this utility model is employed the following technical solutions：A kind of steam long-distance sand transport low-loss
Direct-burried insulation construction, is protected by working steel tube, aeroge heat-insulation layer, fiber aluminium foil reflecting layer, super glass wool from inside to outside successively
Warm layer, air layer, steel outer casing, RPUF heat-insulation layer and high density polyethylene (HDPE) trocar sheath are constituted.
Be provided between the aeroge heat-insulation layer and fiber aluminium foil reflecting layer stainless steel band colligation, winding in alkali glass silk cloth
Two-layer.
3 sliding supports are provided between the fiber aluminium foil reflecting layer and steel outer casing.
This utility model adopts the less aeroge of heat conductivity and RPUF heat-insulation layer, can be effective
Ground reduces insulation layer thickness, so as to reduce steel outer casing size, reduces construction costs；Hard polyaminoester is adopted outside steel outer casing
The version of foam insulation and high density polyethylene (HDPE) trocar sheath, when high density polyethylene (HDPE) trocar sheath is destroyed, firmly
Matter polyurethane foam plastics heat-insulation layer can also isolate soil and water, protect steel outer casing not corroded, and extend Buried Steam Pipe
The road life-span.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Steam long-distance sand transport as shown in Figure 1 low-loss direct-burried insulation construction, from inside to outside successively by working steel tube
1st, aeroge heat-insulation layer 2, fiber aluminium foil reflecting layer 4, super glass wool heat-insulation layer 5, air layer 6, steel outer casing 7, hard polyurethane
Ester foamed plastic heat-insulation layer 8 and high density polyethylene (HDPE) trocar sheath 9 are constituted, wherein, aeroge heat-insulation layer 2 and fiber aluminium foil reflecting layer
Be provided between 4 stainless steel band colligation, winding in alkali glass silk cloth two-layer 3, set between fiber aluminium foil reflecting layer 4 and steel outer casing 7
There are 3 sliding supports 10.
