The utility model discloses structural design scientific and reasonable has that the weatherability is strong, increase of service life, uses manpower sparingly, improves the advantage of welding efficiency, convenient operation, is an interior grommet compound steel pipes that weatherability is strong who has higher novelty.
Description
Technical field
This utility model relates to a kind of composite steel tube, and the inner bushing ring that a kind of weatherability is strong is combined
Steel pipe.
Background technology
For the composite steel tube in water delivery field, to its decay resistance and supercool or overtemperature
Adaptability require be all the highest.Existing water delivery composite steel tube mostly is plastic coated composite steel
Pipe, i.e. uniformly sprays plastic layer on the inside and outside wall of steel pipe, thus reaches antiseptical purpose.
But, its weather resistance is poor, for hot water or the conveying of cold water, can make the plastics of its inwall
Coating generation degeneration, in the course of time, will shorten the service life of this composite steel tube；It addition,
Two steel-pipe weldings when, due to welding heating, the anticorrosion knot around weld seam can be destroyed
Structure, thus shorten the service life of anti-corrosive steel tube；It addition, after having welded, also want artificial
Creep into the inwall of butt welded seam in steel pipe to repair, i.e. operate inconvenience, waste time and energy again.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one has design department
Learn rationally, weatherability is strong, increase the service life, saves manpower, improve welding efficiency, convenient grasp
The inner bushing ring composite steel tube made.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
The inner bushing ring composite steel tube that a kind of weatherability is strong, including steel pipe body, it is characterised in that:
Fluorocarbon layer has been uniformly sprayed, at the fluorine carbon of steel pipe body outer wall on the inside and outside wall of described steel pipe body
Layer is outside is provided with epoxy resin layer, also includes stainless steel ring, and this stainless steel ring is lining in steel pipe body
Inwall two ends.
And, described stainless steel ring is made up of the ventilative Concha Arcae of inner bushing ring, external bushing ring and reinforcement, interior
Grommet is arranged concentrically with external bushing ring, is provided with a circle and strengthens ventilative watt between inner bushing ring and external bushing ring
Stupefied, this stainless steel ring is integrally forming with steel pipe body by pressurization, heating.
And, the wall thickness of described steel pipe body is 80-150mm, and after pressurization, the wall thickness of stainless steel ring is
8-15mm。
Advantage of the present utility model and good effect be:
1. the inner bushing ring composite steel tube that this weatherability is strong, by the clad steel at original outer painting epoxy resin
Fluorocarbon layer is set on pipe, utilizes the performance that fluorocarbon layer is excellent, make this composite steel tube reach high temperature resistant,
Low temperature and corrosion resistant feature, thus adapt it to the conveying of hot and cold water and the most cold and hot ring
The adaptation in border；Meanwhile, the surface that fluorocarbon layer is smooth, also reduce the water resistance when conveying.Separately
Outward, by the setting of stainless steel ring, make not worry because temperature is too high steel welding when
The fluorocarbon layer of inside pipe wall damages.
2. the inner bushing ring composite steel tube that this weatherability is strong, saturating by stainless steel ring being designed as built-in reinforcement
The structure of gas Concha Arcae, the breathe freely setting of Concha Arcae of this reinforcement not only plays the effect of reinforcement, and, also
Produced heat during welding can be disperseed, it is to avoid steel pipe and the deformation of stainless steel ring.
3. this utility model scientific structure design is reasonable, has that weatherability is strong, increases the service life, saves
Human-saving, improve welding efficiency, the advantage of convenient operation, be a kind of to there is the resistance to of higher innovation
The inner bushing ring composite steel tube of Hou Xingqiang.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model stainless steel ring；
Fig. 3 is the A portion enlarged drawing of Fig. 2.
Description of reference numerals:
1-epoxy resin layer, 2-steel pipe body, 3-fluorocarbon layer, 4-stainless steel ring, 5-external bushing ring, 6-
Strengthen ventilative Concha Arcae, 7-inner bushing ring.
Detailed description of the invention
Below in conjunction with the accompanying drawings, by specific embodiment, the utility model is described in further detail.Following reality
It is illustrative for executing example, is not determinate, it is impossible to limit protection model of the present utility model with this
Enclose.
The inner bushing ring composite steel tube that a kind of weatherability is strong, including steel pipe body 2, its innovation is:
The inside and outside wall of described steel pipe body uniformly sprays fluorocarbon layer 3, at the fluorine of steel pipe body outer wall
It is provided with epoxy resin layer 1 outside carbon-coating, to strengthen the intensity of this composite steel tube, also includes rustless steel
Ring 4, this stainless steel ring is lining in the inwall two ends of steel pipe body.
Described stainless steel ring is made up of the ventilative Concha Arcae 6 of inner bushing ring 7, external bushing ring 5 and reinforcement, liner
Ring is arranged concentrically with external bushing ring, is provided with a circle and strengthens ventilative Concha Arcae between inner bushing ring and external bushing ring,
This stainless steel ring is integrally forming with steel pipe body by pressurization, heating.
The wall thickness of described steel pipe body is 80-150mm, and after pressurization, the wall thickness of stainless steel ring is
8-15mm。
This utility model is by arranging fluorocarbon layer on the composite steel tube of original outer painting epoxy resin, sharp
By the excellent performance of fluorocarbon layer, this composite steel tube is made to reach high temperature resistant, low temperature and corrosion resistant spy
Point, thus adapt it to the conveying of hot and cold water and the adaptation of hot-cool environment to external world；Meanwhile, fluorine
The surface that carbon-coating is smooth, also reduces the water resistance when conveying.It addition, by stainless steel ring
Arrange, make not worry because temperature is too high, the fluorocarbon layer of steel pipe inner wall being caused welding when
Destroy.Breathe freely the structure of Concha Arcae by stainless steel ring being designed as built-in reinforcement, ventilative watt of this reinforcement
The effect of reinforcement is not only played in stupefied setting, and, also produced heat during welding can be carried out
Dispersion, it is to avoid steel pipe and the deformation of stainless steel ring.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but this area
Those of skill will appreciate that: without departing from this utility model and spirit and scope of the appended claims
In, various replacements, to change and modifications be all possible, therefore, and scope of the present utility model not office
It is limited to embodiment and accompanying drawing disclosure of that.
