Abstract
The invention relates to a simple three-layer heat insulation pipe which comprises a steel core, a heat insulation layer and an anti-corrosion layer, and is characterized in that the steel core is located on the innermost layer; the heat insulation layer is arranged outside the steel core; and the anti-corrosion layer is arranged outside the heat insulation layer, and coated by anti-corrosion paint. The simple three-layer heat insulation pipe is reasonable in structure and simple in fabrication technique.
Description
Technical field
The present invention relates to field of heat insulating materials, specifically is a kind of simple and easy three layers of thermal insulation pipe.
Background technique
Booth is as the critical facility of scale agricultural production, and the Winter protection of booth is a big problem, the thermal insulation pipe hot channel of applauding again, and according to main material ground difference, thermal insulation pipe generally is divided into two classes, and the one, steel bushing steel compound thermal insulating pipe, the 2nd, polyurethane thermal pipe.No matter which kind of thermal insulation pipe, its body mainly is made up of four parts.(1) working steel tube: adopt seamed steel pipe, seamless steel pipe, two-sided submerged arc spiral welded steel pipe respectively according to the technical requirements of fed sheet of a media.(2) thermal insulation layer: adopt RPUF.(3) containment vessel: adopt high density polyethylene (HDPE) or glass fibre reinforced plastics.(4) leakage alarm line: when making the high temperature prefabricated direct-buried thermal insulation pipe, in the close thermal insulation layer of steel pipe, be embedded with alarming line, in case seepage takes place in the pipeline somewhere, conduction by alarm line, just can report alert and demonstrate the accurate position that leaks and the size of seepage degree in the dedicated test instrument, in order to notify the maintainer to handle the pipeline section that leaks rapidly, guarantee the heat supply network safe operation.
On the market thermal insulation pipe or heat insulation effect are undesirable, or cost is too high.Also there are not three layers of thermal insulation pipe a kind of simple in structure, with low cost, convenient and practical at present.
Summary of the invention
The present invention provides a kind of respond well just at above technical problem, simple and easy three layers of thermal insulation pipe simple in structure.
The present invention is achieved through the following technical solutions:
A kind of simple and easy three layers of thermal insulation pipe comprise steel core, thermal insulation layer, corrosion-resistant coating, it is characterized in that steel core is positioned at the innermost layer, and steel core is outside equipped with a circle thermal insulation layer, and thermal insulation layer is outside equipped with corrosion-resistant coating.Corrosion-resistant coating adopts the corrosion resistant coating coating to form.
The present invention is simple in structure, and is with low cost, easy to use.
Description of drawings
In the accompanying drawing, Fig. 1 is cross sectional representation of the present invention, wherein:
The 1-steel core, 2-thermal insulation layer, 3-corrosion-resistant coating.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing:
A kind of simple and easy three layers of thermal insulation pipe comprise steel core 1, thermal insulation layer 2, corrosion-resistant coating 3, it is characterized in that steel core 1 is positioned at the innermost layer, and steel core 1 is outside equipped with a circle thermal insulation layer 2, and thermal insulation layer 2 is outside equipped with corrosion-resistant coating 3.Corrosion-resistant coating 3 adopts the corrosion resistant coating coating to form.
The present invention is rational in infrastructure, and preparation process is simple.
Claims (2)
