The metal ceramic steam direct-buried conduit adopts a plurality of high-tech materials to do heat-insulation, corrosion-proof, wear-resisting and thermostable process for the work steel plate, which has the advantages of obvious heat-insulating effect, long service span, light integral weight, low production cost, excellent sealing property and the like, and is particularly suitable for central heating enterprises and power plants.
Description
Technical field
The utility model relates to a kind of direct embedment steel pipe, especially relates to a kind of ceramet insulated steam pipe.
Background technique
In existing technology, " steel bushing steel " direct embedment steel pipe is used commonplace, general employing innermost layer is a service pipe, service pipe is provided with thermal insulation layer outward, outermost surface is an outer steel pipe, and its thermal insulation layer adopts centrifugally glass-wool, and working steel tube directly contacts with high-temperature steam, resistance to high temperature is poor, and does not have corrosion-resistant function; Outer steel pipe adopts the welded tube structure, and working strength is poor, increase steel use amount, cost height; The anticorrosion with painting technology is adopted on the outer steel pipe surface, does not possess stronger antiseptic property; Shortcomings such as it is poor to have heat insulation effect on the whole, and cost is high, and pipeline weight is big, and construction intensity is big, and antiseptic property is poor, working life is short.
The model utility content
The utility model provides the ceramet insulated steam pipe at the deficiencies in the prior art.
For realizing the above object, the technical solution adopted in the utility model is:
The ceramet insulated steam pipe is made up of working steel tube, ceramic layer, heat insulation rolling support, thermal insulation layer, fire-retardant reflecting layer, air layer, outer steel pipe and external anti-corrosion layer; Wherein the inboard of working steel tube is a ceramic layer, the outside is distributed with thermal insulation layer from inside to outside successively, fire-retardant reflecting layer, air layer, outer steel pipe and external anti-corrosion layer, working steel tube links to each other with outer steel pipe by heat insulation rolling support, utilize air-right structure to form thermal insulation layer and air layer, thermal insulation layer selects for use high temperature glass wool to be made, high insulating effect, insulation layer surface is coated with fire-retardant reflecting layer, form air layer between fire-retardant reflecting layer and the outer steel pipe, if adopt the technology that vacuumizes, can stop the electrochemical corrosion that the outer steel pipe inboard is caused by moisture substantially, the outer steel pipe outside is an external anti-corrosion layer, adopts zinc-plated add antifouling paint or plastic-blasting preservative treatment.
Described working steel tube is that the zinc-plated volute of metal, outer steel pipe adopt zinc-plated spiral crest pipe, has intensity height, light specific gravity, good seal performance, can effectively discharge water, impervious effect.
The utility model adopts the inner fixed support technology, and the overall work steel pipe is in hermetically sealed environment, have simple in structure, high insulating effect, long service life, beneficial features such as safe and reliable.
Description of drawings
Fig. 1 is the utility model structural drawing;
Embodiment:
As shown in Figure 1, a kind of ceramet direct embedment steel pipe is made up of working steel tube 1, ceramic layer 2, heat insulation rolling support 3, thermal insulation layer 4, fire-retardant reflecting layer 5, air layer 6, outer steel pipe 7 and external anti-corrosion layer 8; Wherein working steel tube 1 is the zinc-plated volute of metal, its inboard is a ceramic layer 2, ceramic layer adopts alloy ceramic to make, its intensity and hardness all are better than iron and steel, have high temperature resistant, wear-resisting, corrosion resistant characteristics, the outside is followed successively by thermal insulation layer 4 from the inside to the outside, fire-retardant reflecting layer 5, air layer 6, outer steel pipe 7 and external anti-corrosion layer 8, working steel tube 1 outside is fixed with a plurality of heat insulation rolling supports 3, heat insulation rolling support 3 is equally spaced around working steel tube 1, and be connected with outer steel pipe 7, because of heat insulation rolling support 3 adopts extraordinary low hot material, surface friction drag is little during the service pipe operation, and can effectively prevent the generation of service pipe 1 heat bridge, heat insulation rolling support 3 adopts the inner fixed support technology, can fully phase out the outer fixing concrete buttress, thermal insulation layer 4 is made of special thermal insulating material, it is movable together to follow working steel tube 1, the width of air layer 6 is about 10-20mm, both can do the humidity discharging passage, can do signal pipe line again uses, if it is pumped into rough vacuum, but the moisture that absorbs in moisture in the deaeration layer 6 and the thermal insulation layer 4, substantially stop the electrochemical corrosion that outer steel pipe 7 inboards are caused by moisture, more effectively improve heat insulation effect, outer steel pipe 7 adopts zinc-plated spiral crest pipe, and the external anti-corrosion layer 8 in its outside adopts zinc-plated and antifouling paint is handled.
The utility model adopt multiple hitech materials to working steel tube be incubated, anticorrosion, Wear-resisting, high temperature resistant processing, it is obvious to have a heat insulation effect, long service life, overall weight is light, The beneficial features such as cost is low, and the water-tight performance is good, be particularly suitable for heating enterprise and power plant use.
