Abstract
Light heat insulating pipe, it is made up of steel pipe body, hard polyurethane foam heat-insulation layer, high density polyethylene (HDPE) outer tube, foamed ceramics layer and epoxide powder coating layer, filled polyurethane rigid foam heat-insulation layer between high density polyethylene (HDPE) outer sleeve inner wall and steel pipe body outer surface, foamed ceramics layer is bonded in steel pipe inner body wall, and epoxide powder coating layer is coated on foamed ceramics layer inner surface.The utility model sets foamed ceramics layer and epoxide powder coating layer in the steel pipe body internal surface of insulating tube, using foamed ceramics lightweight, heat-insulated and outstanding corrosion resistance, and combine the corrosion resistance and toughness of epoxide powder coating, while excellent heat-insulating property is kept, reduce the thickness of polyurethane cardboard foam heat-insulation layer, the total quality of insulating tube is reduced, and realizes the corrosion resistance of insulating tube.
Description
Technical field
The utility model is related to anti-corrosion pipe production technical field, and in particular to a kind of light heat insulating pipe.
Background technology
Insulating tube is the abbreviation of insulated piping, and insulating tube is used for the conveying of liquid, gas and other media, in oil, is changed
The adiabatic heat-insulation engineering of the pipelines such as work, space flight, military affairs, central heating, central air-conditioning, municipal administration.Insulating tube in the market is big
It is many that using in outer surface of steel tube, polyurethane foam insulation layer is set, although the thermal conductivity factor of polyurethane foam is low, polyurethane foam
Foam volume density compares larger, causes insulating tube weight big, and transport is inconvenient, and the corrosion resistance of insulating tube is also managed not to the utmost
Think, etching problem easily occurs in steel pipe.
Utility model content
The utility model provides a kind of light heat insulating pipe, and big with the weight for solving prior art presence, transport is not
The convenient and undesirable problem of corrosion resistance.
The utility model solves the technical scheme that its technical problem used：
A kind of light heat insulating pipe, by steel pipe body, hard polyurethane foam heat-insulation layer, high density polyethylene (HDPE) overcoat
Pipe, foamed ceramics layer and epoxide powder coating layer composition, between high density polyethylene (HDPE) outer sleeve inner wall and steel pipe body outer surface
Filled polyurethane rigid foam heat-insulation layer, foamed ceramics layer is bonded in steel pipe inner body wall, and epoxide powder coating layer is coated in
On foamed ceramics layer inner surface.
Foamed ceramics layer of the present utility model has the low-down coefficient of heat conduction, and relative to rigid polyurethane vacuum
Body has the advantages that the low lightweight of density, and epoxide powder coating layer has outstanding corrosion resistance and toughness.
The utility model sets foamed ceramics layer and epoxide powder coating layer in the steel pipe body internal surface of insulating tube, utilizes
Foamed ceramics lightweight, heat-insulated and outstanding corrosion resistance, and the corrosion resistance and toughness of epoxide powder coating are combined, protecting
While holding excellent heat-insulating property, the thickness of polyurethane cardboard foam heat-insulation layer is reduced, reduce the overall matter of insulating tube
Amount, and realize the corrosion resistance of insulating tube.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the utility model production system.
1 steel pipe body, 2 hard polyurethane foam heat-insulation layers, 3 high density polyethylene (HDPE) outer tubes, 4 foamed ceramicses layer, 5 in figure
Epoxide powder coating layer.
Specific embodiment
As illustrated, a kind of light heat insulating pipe, by steel pipe body 1, hard polyurethane foam heat-insulation layer 2, high density
Polyethylene jacket pipe 3, foamed ceramics layer 4 and the composition of epoxide powder coating layer 5, the inwall of high density polyethylene (HDPE) outer tube 3 and steel pipe
Filled polyurethane rigid foam heat-insulation layer 2 between the outer surface of body 1, foamed ceramics layer 4 is bonded on the inwall of steel pipe body 1, ring
Oxygen powder coating layer 5 is coated on foamed ceramics 4 inner surface of layer.
Foamed ceramics layer of the present utility model has the low-down coefficient of heat conduction, and relative to rigid polyurethane vacuum
Body has the advantages that the low lightweight of density, and epoxide powder coating layer has outstanding corrosion resistance and toughness.
The utility model sets foamed ceramics layer and epoxide powder coating layer in the steel pipe body internal surface of insulating tube, utilizes
Foamed ceramics lightweight, heat-insulated and outstanding corrosion resistance, and the corrosion resistance and toughness of epoxide powder coating are combined, protecting
While holding excellent heat-insulating property, the thickness of polyurethane cardboard foam heat-insulation layer is reduced, reduce the overall matter of insulating tube
Amount, and realize the corrosion resistance of insulating tube.
