Abstract
The utility model relates to a thermal insulation pipe for conveying fluid, particularly a thermal insulation pipe with a plastic strip winding layer. The utility model comprises a thermal insulation layer and a steel pipe. The plastic strip winding layer is arranged on the thermal insulation layer which is covered on the steel pipe. The plastic strip winding layer can be a polyethylene strip winding layer. Firstly, the thermal insulation layer is arranged on the steel pipe; next, a polyethylene strip which is in thermal state is wound on the thermal insulation layer; then, after the cooling of the polyethylene strip winding layer is finished, the polyethylene strip winding layer is adhesively bonded to form a whole casing. When the utility model is adopted, the thermal insulation layer which is surrounded on the steel pipe can be assured to have uniform satiation, and the casing can be tightly assembled with the thermal insulation layer. The utility model has the advantage of good product quality. The utility model can be used for producing the thermal insulation pipe of large pipe diameter.
Description
The utility model relates to the insulation pipe of conveyance fluid, particularly has the thermal insulation pipe of plastic strip winding layer.
Polyurethane thermal insulation pipe traditionally, for filling the polyurethane thermal insulation layer between steel pipe and the polyethylene prefabricated pipe, because the restriction of structure makes the polyurethane thermal insulation pipe of production often have the polyamine ester of filling between steel pipe and the polyethylene prefabricated pipe not full or steel pipe and polyethylene prefabricated pipe decentraction, make polyurethane thermal insulation bed thickness book inhomogeneous, influenced the heat insulation effect of pipeline, it is not tight also to exist the polyethylene prefabricated pipe to combine with the polyurethane thermal insulation layer, produce two-layer skin, influenced the quality of product, and the polyurethane thermal insulation pipe can not be produced the thermal insulation pipe of big caliber owing to the restriction of structure traditionally.
The purpose of this utility model is to provide a kind of thermal insulation pipe with plastic strip winding layer, not only can make the shell of thermal insulation pipe and the polyurethane thermal insulation layer between the steel pipe evenly full, the polyurethane thermal insulation bed thickness book that guarantees the steel pipe external packets is even, the shell of plastics combines closely with the polyurethane thermal insulation layer, good product quality, and adopt structure of the present utility model can produce the thermal insulation pipe of big caliber.
The utility model is achieved in that a kind of thermal insulation pipe with plastic strip winding layer, comprises thermal insulation layer and steel pipe, and the plastic strip winding layer is being set on the thermal insulation layer that surrounds on the steel pipe.
Because structure of the present utility model is to set in advance thermal insulation layer on the outer wall of steel pipe, the plastic strip winding layer is set on thermal insulation layer again, the polyamine ester foam that can overcome filling between the polyethylene sheath of thermal insulation pipe traditionally and the steel pipe is inhomogeneous, do not protect full situation, also overcome the shell of thermal insulation pipe and the phenomenon of steel pipe decentraction, adopted structure of the present utility model can also produce the thermal insulation pipe of big caliber (as: thermal insulation pipe of caliber more than 529mm).
Accompanying drawing is a structural representation of the present utility model, below in conjunction with accompanying drawing the utility model is further described, a kind of thermal insulation pipe that has the plastic strip winding layer, comprise thermal insulation layer and steel pipe, on the thermal insulation layer (2) that steel pipe (3) upward surrounds, plastic strip winding layer (1) is being set, plastic strip winding layer (1) can be a polyethylene band winding layer, plastic strip winding layer (1) can be a high density polyethylene (HDPE) band winding layer, thermal insulation layer (2) can be the polyamine ester foam, also can be polyamine urea acid esters foam.This model utility at first is provided with thermal insulation layer (2) on steel pipe (3), plastic strip with hot state is wrapped on the thermal insulation layer (2) then, after plastic strip winding layer (1) cooling of the hot state on thermal insulation layer (2) to be wound, plastic strip winding layer (1) bonds together the formation monolithic case.The utility model can be widely used in the hot water heating of Heat Supply Engineering or the transmission pipeline network of steam heating, is used for the pipe network that heat-insulating oil pipeline and extremely frigid zones frozen soil layer are buried underground.
Claims (4)
1, a kind of thermal insulation pipe with plastic strip winding layer comprises thermal insulation layer and steel pipe, it is characterized in that on the thermal insulation layer (2) that steel pipe (3) upward surrounds plastic strip winding layer (1) being set.
