Description
Technical field
The present invention relates to a kind of anti-corrosive steel tube, particularly a kind of heavy caliber anti-corrosive steel tube.
Background technology
Anti-corrosive steel tube refers to by anticorrosion process working process, can effectively prevent or slow down in transport with being sent out during use
The steel pipe of corrosion phenomenon occurs for biochemical or electrochemical reaction.Existing anti-corrosive steel tube is mostly the surfaces externally and internally spray in steel pipe
Corrosion-inhibiting coating is applied, but for it can not use the large-diameter steel pipe that flange or other connectors connect, in two steel-pipe weldings
When, because welding is generated heat, the anticorrosion structure around weld seam can be destroyed, so as to shorten the service life of anti-corrosive steel tube；In addition,
After having welded, also manually to creep into steel pipe and the inwall of weld seam is repaired, be i.e. operation inconvenience, waste time and energy again.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind have design science rationally, extend use
In the life-span, save manpower, improve welding efficiency, the heavy caliber anti-corrosive steel tube of convenient operation.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of heavy caliber anti-corrosive steel tube, including anti-corrosive steel tube body, it is characterised in that：Also include stainless steel ring, described
Stainless steel ring is lined with the both ends inwall of anti-corrosive steel tube body, described stainless steel ring is by inner bushing ring, external bushing ring and strengthens ventilative
Corrugation is formed, and inner bushing ring is arranged concentrically with external bushing ring, and a circle is provided between inner bushing ring and external bushing ring and strengthens ventilative corrugation, should
Stainless steel ring is integrally formed by pressurizeing, heating with anti-corrosive steel tube body.
Moreover, the wall thickness of the anti-corrosive steel tube body is 80-150mm, the wall thickness of stainless steel ring is 8-15mm after pressurization.
The advantages and positive effects of the present invention are：
A 1. heavy caliber anti-corrosive steel tube, by the both ends inner liner stainless steel ring in original anti-corrosive steel tube, so in welding
When just do not have to worry to damage the corrosion-inhibiting coating of steel pipe inner wall because temperature is too high, meanwhile, this new stainless steel ring
It is the built-in structure for strengthening ventilative corrugation, reinforcement is not only played a part of in the setting of the ventilative corrugation of the reinforcement, moreover, also can butt welding
Caused heat is disperseed when connecing, and avoids the deformation of anti-corrosive steel tube and stainless steel ring.
2. scientific structure design of the present invention is reasonable, has and increase the service life, save manpower, raising welding efficiency, conveniently
The advantages of operation, it is a kind of heavy caliber anti-corrosive steel tube with higher innovation.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of stainless steel ring of the present invention；
Fig. 3 is Fig. 2 A portions enlarged drawing.
Description of reference numerals：
1- anti-corrosive steel tubes body, 2- stainless steel rings, 3- external bushing rings, 4- strengthen ventilative corrugation, 5- inner bushing rings.
Embodiment
Below in conjunction with the accompanying drawings, by specific embodiment, the invention will be further described.Following examples are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of heavy caliber anti-corrosive steel tube, including anti-corrosive steel tube body 1, it is characterised in that：Also include stainless steel ring 2, in institute
State and stainless steel ring is lined with the both ends inwall of anti-corrosive steel tube body, described stainless steel ring is by inner bushing ring 5, external bushing ring 3 and strengthens
Ventilative corrugation 4 is formed, and inner bushing ring is arranged concentrically with external bushing ring, and a circle is provided between inner bushing ring and external bushing ring and strengthens ventilative watt
Stupefied, the stainless steel ring is integrally formed by pressurizeing, heating with anti-corrosive steel tube body.
The wall thickness of the anti-corrosive steel tube body is 80-150mm, and the wall thickness of stainless steel ring is 8-15mm after pressurization.
The present invention so does not just have to worry by the both ends inner liner stainless steel ring in original anti-corrosive steel tube when welding
The corrosion-inhibiting coating of steel pipe inner wall is damaged because temperature is too high, meanwhile, this new stainless steel ring is that built-in reinforcement is ventilative
The structure of corrugation, the reinforcement breathe freely corrugation settings not only play a part of reinforcement, moreover, also can to weld when caused heat
Amount is disperseed, and avoids the deformation of anti-corrosive steel tube and stainless steel ring.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, those skilled in the art can manage
Solution：Do not departing from the present invention and spirit and scope of the appended claims in, it is various replace, change and modifications all be it is possible,
Therefore, the scope of the present invention is not limited to embodiment and accompanying drawing disclosure of that.
Claims (2)
1. a kind of heavy caliber anti-corrosive steel tube, including anti-corrosive steel tube body, it is characterised in that：Also include stainless steel ring, described anti-
Stainless steel ring is lined with the both ends inwall of rotten steel pipe body, described stainless steel ring is by inner bushing ring, external bushing ring and ventilative watt of reinforcement
Stupefied composition, inner bushing ring are arranged concentrically with external bushing ring, and a circle is provided between inner bushing ring and external bushing ring and strengthens ventilative corrugation, this is not
Rust steel loop is integrally formed by pressurizeing, heating with anti-corrosive steel tube body.
A kind of 2. heavy caliber anti-corrosive steel tube according to claim 1, it is characterised in that：The wall thickness of the anti-corrosive steel tube body
