At present, hot galvanized steel pipe be widely used in building, machinery, colliery, chemical industry, rail truck, auto industry, highway,
The process industries such as bridge, container, sports equipment, agricultural machinery, petroleum machinery, mine locating machinery.So-called hot galvanized steel pipe be
Steel tube surface has dip galvanized, the zinc-plated resistance to corrosion for increasing steel pipe, increases the service life, the purposes of galvanized pipe is very
Extensively, in addition to the line pipe for making the general low-pressure fluid such as water delivery, coal gas, oil, petroleum industry particularly marine oil field is also served as
Oil well pipe, petroleum pipeline, oil heater, condensate cooler, the coal of chemical industry coker evaporate washing oil exchanger pipe, and trestle pipe
Stake, the support rack pipe etc. in mine tunnel.
But for the hot galvanized steel pipe of exposed application, due to being subjected to exposing to the weather for a long time and extraneous oxidation is rotten
Erosion etc., easily causes hot galvanized steel pipe to be undermined reduction of service life.In the case where shining upon, tube wall also easily it is heated cause it is defeated in pipe
, potential safety hazard be present in the material overheat sent.
Therefore, it is badly in need of working out a kind of new technical scheme to solve the above problems.
Utility model content
In view of this, the utility model in view of the existing deficiencies of the prior art, its main purpose be to provide a kind of safety every
Hot galvanized steel pipe inside and outside heat type, it enhances the performance of heat-insulated, fire-retardant, antiultraviolet etc., extends service life, especially
Be, burning hot summer, big fire occurs when, the structural strength and performance of hot dip galvanizing pipe can be guaranteed, it is ensured that hot dip
The safety in utilization of zinc pipe.
To achieve the above object, the utility model is using following technical scheme：
Hot galvanized steel pipe inside and outside a kind of safe heat insulation type, include steel pipe body, the internal face of the steel pipe body is in
And the first hot galvanized layer, epoxy static conducting oil resistance anticorrosion layer are disposed with outside, the outside wall surface from-inner-to-outer of the steel pipe body
It is disposed with the second hot galvanized layer, chromium coating, thermal insulation layer, flame-retardant layer, ultraviolet resistant layer, wearing layer.
As a kind of preferred scheme, first hot galvanized layer, the thickness of second hot galvanized layer are 15~18 μ
M, the thickness of the chromium coating is 12~15 μm.
As a kind of preferred scheme, the thermal insulation layer is aluminium foil thermal insulation layer, and the flame-retardant layer is APP flame-retardant layer, institute
It is rubber wear-resisting layer to state wearing layer.
As a kind of preferred scheme, the outer surface of the steel pipe is wound with PE and strengthens overcoat, and the PE strengthens overcoat
On the outside of foregoing wear layer.
As a kind of preferred scheme, the internal face of the steel pipe body is convexly equipped with some reinforcement convex tendons.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme understands that, mainly by carrying out improvement design to traditional hot galvanized steel pipe, the design of its multi-layer compound structure enhances for it
The performance of heat-insulated, fire-retardant, antiultraviolet etc., extend service life, especially, burning hot summer, big fire occurs when, heat
The structural strength and performance of galvanized pipe can be guaranteed, it is ensured that the safety in utilization of hot dip galvanizing pipe.
More clearly to illustrate architectural feature, technological means and its specific purposes and work(reached of the present utility model
Can, the utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
