Abstract
The utility model discloses a kind of galvanized pipe, including galvanized pipe matrix, plastic tube is arranged with the galvanized pipe matrix, packing layer is provided with the cavity between plastic tube and galvanized pipe, coating steel pipe outer wall is provided with zinc coat and passivation layer.The galvanized pipe adds the intensity of galvanized pipe, it is not easy to deform by being provided with packing layer in the interior plastic pipe-covered and interlayer cavity body of zinc-plated tube body, and does not influence the use of body, extends service life；And the plastic tube and packing layer being provided with galvanized pipe also increase the corrosion resistance of galvanized pipe, during long-term use, will not because of fluid inside flowing, the galvanized pipe on the outside of corrosion also functions to the effect increased the service life.
Description
Technical field
The utility model is related to the zinc-plated field of steel pipe, especially a kind of galvanized pipe.
Background technology
Galvanized pipe, also known as coating steel pipe, are divided into two kinds of galvanizing and electrogalvanizing, hot dip galvanizing pipe is to make molten metal and iron-based
Precursor reactant alloy-layer, so that both matrix and coating are combined.Galvanized pipe is internal easily to produce knot after long-term use
Dirt, easily get rusty, inwall it is rough, there is low intensity in reduction of service life, the galvanized pipe that current petrochemical industry is used, easily
Deform the short shortcoming of service life.
Utility model content
The purpose of this utility model is to overcome of the prior art not enough there is provided a kind of galvanized pipe, the galvanized pipe by
Packing layer is provided with the interior plastic pipe-covered and interlayer cavity body of zinc-plated tube body, the intensity of galvanized pipe is added, and do not influence pipe
The use of body, extends service life.
What the technical solution of the utility model was realized in：A kind of galvanized pipe, including galvanized pipe matrix, the galvanized pipe
Plastic tube is arranged with matrix, packing layer is provided with the cavity between plastic tube and galvanized pipe, coating steel pipe outer wall is provided with zinc-plated
Layer and passivation layer.
Preferably, described filler layer includes pitch, elastomer and inorganic fillings composition.
As another preferred, heat-insulation layer is provided with the outside of the passivation layer.It is provided at an outer portion with heat-insulation layer so that too low in temperature
Under conditions of, it can also use.
Compared with prior art, advantage of the present utility model is as follows：The galvanized pipe passes through the interior plastic sleeve in zinc-plated tube body
Packing layer is provided with expects pipe and interlayer cavity body, the intensity of galvanized pipe is added, it is not easy to deform, and do not influence making for body
With extending service life；And the plastic tube and packing layer being provided with galvanized pipe also increase the corrosion resistance of galvanized pipe, in length
During phase use, will not because of fluid inside flowing, the galvanized pipe on the outside of corrosion also functions to the work increased the service life
With.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is as follows：
Embodiment 1：As shown in Figure 1：Modeling is arranged with a kind of galvanized pipe, including galvanized pipe matrix 1, the galvanized pipe matrix
Packing layer 3 is provided with expects pipe 2, the cavity between plastic tube and galvanized pipe, coating steel pipe outer wall is provided with zinc coat 4 and passivation layer 5.
Described filler layer includes pitch, elastomer and inorganic fillings composition.Heat-insulation layer is provided with the outside of the passivation layer.It is provided at an outer portion with
Heat-insulation layer so that under conditions of temperature is too low, can also be used；And the plastic tube and packing layer being provided with galvanized pipe also increase
The corrosion resistance of galvanized pipe, during long-term use, will not because of fluid inside flowing, the galvanized pipe on the outside of corrosion,
Also function to the effect increased the service life.
The galvanized pipe adds plating by being provided with packing layer in the interior plastic pipe-covered and interlayer cavity body of zinc-plated tube body
The intensity of zinc pipe, it is not easy to deform, and the use of body is not influenceed, extend service life.
Finally it is pointed out that above example is only the more representational example of the utility model.Obviously, this practicality is new
The technical scheme of type is not limited to above-described embodiment, can also there is many deformations.One of ordinary skill in the art can be from this reality
All deformations for directly being exported or being associated with new disclosure, are considered as protection domain of the present utility model.
