Description
Technical field
It the utility model is related to jet chimney technical field, and in particular to a kind of inner sliding type steel-sleeve steel steam pipe.
Background technology
In heating industry, jet chimney demand increasingly increased in recent years, beautiful with the increasingly standardization of urban construction
Change the certainty that city has become development, aerial laying originally is gradually substituted with in-duct installation mode by directly buried technology.
Because jet chimney pumped (conveying) medium temperature is higher, many problems are brought for example to directly buried pipeline：Expansion compensation, waterproof
Sealing, stress rupture and anti-corrosion.
Utility model content
The utility model provides a kind of inner sliding type steel-sleeve steel steam pipe, is mended with solving to expand existing for prior art
Repay, waterproof sealing and the problem of stress rupture.
Technical scheme is used by the utility model solves its technical problem：
A kind of inner sliding type steel-sleeve steel steam pipe, by interior steel pipe, high temperature resistant zinc rich primer layer, alumina silicate drag reduction layer, micropore
Calcium silicates inorganic insulating layer, hard polyaminoester organic heat-insulating layer and outer protection steel pipe composition, high temperature resistant zinc rich primer layer are coated in
In interior steel tube surface, alumina silicate drag reduction layer is coated on high temperature resistant zinc rich primer layer surface, microporous calcium silicate inorganic insulating layer and hard
The heat-insulation layer that matter polyurethane organic heat-insulating layer is formed is arranged on alumina silicate drag reduction layer surface, and outer protection steel pipe is arranged on heat-insulation layer table
Face.
Aluminium foil reflecting layer is set between above-mentioned microporous calcium silicate inorganic insulating layer and hard polyaminoester organic heat-insulating layer.
Above-mentioned outer protection steel tube surface anticorrosive coating.
The utility model uses steel sleeve steel agent structure, and the interior steel tube surface in jet chimney is provided with organic heat-insulating
Layer and the insulation construction that is compounded to form of inorganic insulating layer, be effectively prevented direct-buried steam pipeline expanded by heating, waterproof sealing and
The problem of stress rupture, there is the advantages of intensity is high, convenient construction and service life are long, suitable for 2.5MPa and 350 DEG C of conveying
Following steam or other media.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Steel pipe, 2 high temperature resistant zinc rich primer layers, 3 alumina silicate drag reduction layers, 4 microporous calcium silicate inorganic insulating layers, 5 aluminium in 1 in figure

Embodiment
As illustrated, a kind of inner sliding type steel-sleeve steel steam pipe, by interior steel pipe 1, high temperature resistant zinc rich primer layer 2, alumina silicate
Drag reduction layer 3, microporous calcium silicate inorganic insulating layer 4, hard polyaminoester organic heat-insulating layer 6 and outer protection steel pipe 7 form, and high temperature resistant is rich
For yellow zinc chromate primer paint layer 2 coated on the interior surface of steel pipe 1, alumina silicate drag reduction layer 3 is coated on the surface of high temperature resistant zinc rich primer layer 2, microporous silicon
The heat-insulation layer that sour calcium inorganic insulating layer 4 and hard polyaminoester organic heat-insulating layer 6 is formed is arranged on the surface of alumina silicate drag reduction layer 3, outside
Protection steel pipe 7 is arranged on insulation layer surface, is set between microporous calcium silicate inorganic insulating layer and hard polyaminoester organic heat-insulating layer
Aluminium foil reflecting layer 5, the outer protection surface anticorrosive coating 8 of steel pipe 7.
The utility model uses steel sleeve steel agent structure, and the interior steel tube surface in jet chimney is provided with organic heat-insulating
Layer and the insulation construction that is compounded to form of inorganic insulating layer, be effectively prevented direct-buried steam pipeline expanded by heating, waterproof sealing and
The problem of stress rupture, there is the advantages of intensity is high, convenient construction and service life are long, suitable for 2.5MPa and 350 DEG C of conveying
Following steam or other media.
