Abstract
The utility model discloses a Dn1400 high-density polyethylene polyurethane heat-insulation steel pipe which comprises a steel pipe (1) and an insulating layer (2), and is characterized in that the insulating layer (2) is wrapped outside the steel pipe (1), and is externally sheathed with an outer protecting pipe (3). The insulating layer (1) is made of polyurethane, and the outer protecting pipe (3) is made of high-density polyethylene. In the utility model, the outer protecting pipe is sheathed at the outmost surface, the insulating layer can adopt polyurethane materials, and polyurethane foaming equipment implements the polyurethane foam filling on gaps between the outer protecting pipe and the steel pipe so as to form the insulating layer. Therefore, the Dn1400 high-density polyethylene polyurethane heat-insulation steel pipe has the insulating layer formed by the outer protecting pipe and high-efficiency heat-insulation materials, and compact structure formed by the steel pipe, achieves the effects of convenient manufacturing, transportation and installation, and is difficult to be damaged, and good in insulating effect.
Description
Affiliated technical field
The utility model belongs to a kind of pipeline equipment part, a kind of specifically insulating steel tube.
Background technique
At present, in the pipeline equipment manufacture,, often to make insulating steel tube according to the needs of actual conditions.In the prior art, insulating steel tube includes: steel pipe and thermal insulation layer.The deficiency of its existence is: in practical operation, after steel pipe being installed and fixed,, like this, brought many troubles to execute-in-place at its outer package thermal insulation layer, and inefficiency, labor intensity is big, and heat insulation effect is poor.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of insulating steel tube is provided, and its compact structure is easy to install and use, high insulating effect.
For reaching above-mentioned purpose, the utility model is taked following technological scheme: the utility model includes: steel pipe, thermal insulation layer is characterized in that: thermal insulation layer is coated on the steel pipe outside, and the outside of thermal insulation layer is set with outer pillar.
The utility model is taked technique scheme, have following beneficial effect: the utility model is pillar outside outermost is set with, thermal insulation layer can adopt polyurethane material, implements polyurethane foam by the gap between external pillar of polyurethane foam equipment and the steel pipe and fills, and forms thermal insulation layer.Like this, the utlity model has the thermal insulation layer that forms by outer pillar, thermal insulation material, the compact structure that steel pipe is formed, reached manufacturing, transportation, effect easy for installation, and not fragile, high insulating effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model embodiment's a structure diagram.
Mark among the figure: 1-steel pipe, 2-thermal insulation layer, the outer pillar of 3-.
Embodiment
By shown in Figure 1, the utility model includes: steel pipe 1, thermal insulation layer 2, outer pillar 3.Thermal insulation layer 2 is coated on steel pipe 1 outside, and the outside of thermal insulation layer 2 is set with outer pillar 3.
Thermal insulation layer 2 of the present utility model is a polyurethane, adopts floride-free foamed products to carry out polyurethane foam.Outer pillar 3 is the high density polyethylene (HDPE) material.
The utility model can be made the heavy caliber product, and specification reaches DN1400, like this, can increase area of heat-supply service greatly, and it is less to increase investment.
