Technical field

The present invention relates to steel pipe technical fields, more particularly to a kind of insulating steel tube.

Background technique

Central heating refers to steam, hot water as caused by central heat source, supplies a city (town) or portion by pipe network The mode of heat needed for subregion production, heating and life.Central heating is one of infrastructure of modern city, and One critical facility of urban public utilities.

Central heating refers to using hot water or steam as heating agent, from one or more heat sources by heat supply network to city, town or Some of them region heat user supplies the mode of thermal energy, has become one of the important infrastructure in modernization cities and towns at present, is city The important component of town public utilities.Hot duct is the most important component part of central heating system, existing this pipe The heat insulation and preservation effect in road is bad, and corrosion resistance is bad.

Summary of the invention

The invention mainly solves the technical problem of providing a kind of insulating steel tube, there is preferable heat insulation and preservation effect and resistance to Corrosive nature.

In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of insulating steel tube is provided, comprising: Steel pipe body, the outside of the steel pipe body are provided with aluminium foil thermal insulation layer, and the outside of the aluminium foil thermal insulation layer is provided with interior corrosion resistant Rubber layer is lost, the outside of the interior anti-corrosive rubber layer is provided with outer anti-corrosive rubber layer, and the wall thickness of the steel pipe body is 5 ~ 8mm。

In a preferred embodiment of the present invention, the interior anti-corrosive rubber layer is butadiene rubber layer.

In a preferred embodiment of the present invention, the outer anti-corrosive rubber layer is neoprene layer.

In a preferred embodiment of the present invention, the wall thickness of the steel pipe body is 0.6 centimetre.

The beneficial effects of the present invention are: insulating steel tube of the present invention, has preferable heat insulation and preservation effect and corrosion resistance.

Specific embodiment

The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects It encloses.

The embodiment of the present invention includes:

A kind of insulating steel tube, comprising: steel pipe body, the outside of the steel pipe body are provided with aluminium foil thermal insulation layer, so that of the invention Has the function of heat-insulation and heat-preservation.

The outside of the aluminium foil thermal insulation layer is provided with interior anti-corrosive rubber layer, the external setting of the interior anti-corrosive rubber layer There is outer anti-corrosive rubber layer, the interior anti-corrosive rubber layer and outer anti-corrosive rubber layer enhance corrosion resistance of the invention.

The wall thickness of the steel pipe body is 5 ~ 8mm.

The interior anti-corrosive rubber layer is butadiene rubber layer.

The outer anti-corrosive rubber layer is neoprene layer.

Preferably, the wall thickness of the steel pipe body is 0.6 centimetre.

Insulating steel tube of the present invention has preferable heat insulation and preservation effect and corrosion resistance.Suitable for city central heating Construction.

The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks Domain is included within the scope of the present invention.
