Abstract
The utility model provides a corrosion prevention and heat preservation pipeline which comprises a pipeline, wherein the pipeline is successively provided with a corrosion prevention layer, a high-temperature resistant layer, a heat preservation layer and a metal sleeve from inward to outward, wherein the metal sleeve is provided with a raised waved expansion joint pipe which is integrated with the metal sleeve, and the ends of the heat preservation layer and the metal sleeve are provided with waterproof caps. The corrosion prevention layer is a two-layer epoxy powder corrosion prevention layer, and therefore the corrosion prevention is achieved; the end of the heat preservation layer is provided with the waterproof cap so as to prevent the polyurethane heat preservation layer from getting damp due to inflow of water, thus the heat preservation cannot be influenced; the expansion joint pipe is arranged on the metal sleeve so as to prevent the occurrence of the structure heat stress because the heat expansion factors of the pipeline and the metal sleeve are different and therefore the expansion and the extension are different under the high temperature. The pipeline has the advantages of simple structure, good corrosion prevention property, good heat preservation property and the like.
Description
Technical field
The utility model belongs to pipe technology field, especially relates to a kind of corrosion-resistanting insulation pipe.
Background technique
In existing technology, to the requirement of conveyance conduit, be to realize at pipeline outer wrapping one deck insulating heat insulating material, its heat insulation effect is bad, in the situation that particularly medium temperature is high, fed distance is long, can make the flowing medium in pipeline produce larger cooling, cannot meet the conveying requirement of the medium that some flowing medium temperature influence is larger; In addition, pipeline and metal sleeve are inconsistent because of thermal expansion coefficient, and when temperature variation is violent, both deformation extents are inconsistent, affect heat insulation effect; Exist heat insulation effect bad, the problem that antiseptic property is poor.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, antiseptic property good, the corrosion-resistanting insulation pipe of high insulating effect, is especially applicable to the situation that medium temperature is high, fed distance is long.
The technical solution of the utility model is: a kind of corrosion-resistanting insulation pipe, comprise pipeline, pipeline is provided with anticorrosive coat, high-temperature-resistant layer, thermal insulation layer and metal sleeve outward from the inside to the outside successively, described metal sleeve is provided with the expansion pipe joint of the protruding waveform being connected as a single entity with metal sleeve, and the end of described thermal insulation layer and metal sleeve is provided with tarpaulin.
Further, described anticorrosive coat is dual-layer epoxy powder anticorrosive coat.
Further, described thermal insulation layer is polyurethane insulation coating.
Further, the thickness of described high-temperature-resistant layer is 10-50 millimeters.
Further, the thickness of described thermal insulation layer is 60-70 millimeters.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, anticorrosive coat is dual-layer epoxy powder anticorrosive coat, plays antisepsis; Thermal insulation layer end is provided with tarpaulin, avoids in polyurethane insulation coating water inlet moist and affect heat insulation effect; On metal sleeve, being provided with expansion pipe joint, is different in order to prevent because of the thermal expansion coefficient of pipeline and metal sleeve, and the elongation that at high temperature expands is different, causes structure thermal stress; Have simple in structurely, antiseptic property is good, and has the good advantages such as thermal insulation property.
