Abstract
The invention discloses a durable seamless stainless steel tube, which comprises a hollow seamless steel tube body, wherein an inner zinc-plated layer is arranged on the inner wall of the hollow seamless steel tube body; an inner passivation film protection layer is arranged on the outer surface of the inner zinc-plated layer; an outer zinc-plated layer is arranged on the outer wall of the hollow seamless steel tube body; and an outer passivation film protection layer is arranged on the outer surface of the outer zinc-plated layer. Due to the mode, the durable seamless stainless steel tube is suitable to be used as a fluid pipeline, is high in strength, is difficult to corrode and is durable.
Description
Technical field
The present invention relates to the seamless steel pipe technical field, particularly relate to a kind of durable stainless-steel seamless pipe.
Background technique
Seamless steel pipe is widely used in fields such as industrial production, urban construction.Seamless steel pipe has hollow section, a large amount of pipelines as carrying fluid, and the solid steel such as steel pipe and round steel are compared, and when the bending resistance twisting strength was identical, weight was lighter, was a kind of Economic Section steel.Existing seamless steel pipe exists easily as fluid line the time and is corroded, short-life shortcoming.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of durable stainless-steel seamless pipe, can solve problems of the prior art, is suitable as fluid line, and intensity is high, and corrosion-vulnerable is not durable in use.
For solving the problems of the technologies described above; the technological scheme that the present invention adopts is: a kind of durable stainless-steel seamless pipe is provided; comprise: hollow seamless steel pipe body; the inwall of described hollow seamless steel pipe body is provided with interior zinc coat; the outer surface of described interior zinc coat is provided with interior passivating film protective layer; the outer wall of described hollow seamless steel pipe body is provided with the external galvanized layer layer, and the outer surface of described external galvanized layer layer is provided with outer passivating film protective layer.
In a preferred embodiment of the present invention, the thickness of described interior passivating film protective layer is greater than the thickness of interior zinc coat.
In a preferred embodiment of the present invention, the thickness of described outer passivating film protective layer is greater than the thickness of external galvanized layer layer.
In a preferred embodiment of the present invention, described hollow seamless steel pipe body adopts the 316L stainless steel to make.
The invention has the beneficial effects as follows: the durable stainless-steel seamless pipe of the present invention, be suitable as fluid line, intensity is high, and corrosion-vulnerable is not durable in use.
Description of drawings
Fig. 1 is the structural representation of durable stainless-steel seamless pipe one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, hollow seamless steel pipe body, 2, interior zinc coat, 3, interior passivating film protective layer, 4, the external galvanized layer layer, 5, outer passivating film protective layer.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of durable stainless-steel seamless pipe; comprise: hollow seamless steel pipe body 1; the inwall of described hollow seamless steel pipe body 1 is provided with interior zinc coat 2; the outer surface of described interior zinc coat 2 is provided with interior passivating film protective layer 3; the outer wall of described hollow seamless steel pipe body 1 is provided with external galvanized layer layer 4, and the outer surface of described external galvanized layer layer 4 is provided with outer passivating film protective layer 5.
By the combination of interior zinc coat 2, interior passivating film protective layer 3, external galvanized layer layer 4 and outer passivating film protective layer 5, so that seamless steel pipe corrosion-vulnerable not is durable in use.
The thickness of described interior passivating film protective layer 3 is greater than the thickness of interior zinc coat 2.
The thickness of described outer passivating film protective layer 5 is greater than the thickness of external galvanized layer layer 4.
Described hollow seamless steel pipe body 1 adopts the 316L stainless steel to make, and has intensity height, advantage that strength is large.
The durable stainless-steel seamless pipe of the present invention is suitable as fluid line, and intensity is high, and corrosion-vulnerable is not durable in use.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
