Abstract
The utility model relates to an inside lining stainless steel ring's heavy -calibre anticorrosive steel pipe, including the anticorrosive steel pipe body, its characterized in that: still include stainless steel ring the lining has stainless steel ring on the both ends inner wall of anticorrosive steel pipe body, stainless steel ring by interior grommet, outer grommet and strengthen ventilative flute and constitute, interior grommet sets up with outer grommet is concentric including, is provided with the round enhancement flute of breathing freely between grommet and the outer grommet, this stainless steel ring becomes one through pressurization, heating and anticorrosive steel pipe body. The utility model discloses structural design scientific and reasonable has increase of service life, uses manpower sparingly, improves the advantage of welding efficiency, convenient operation, is an inside lining stainless steel ring's heavy -calibre anticorrosive steel pipe who has higher novelty.
Description
Technical field
This utility model relates to a kind of anti-corrosive steel tube, the heavy caliber of a kind of inner liner stainless steel ring
Anti-corrosive steel tube.
Background technology
Anti-corrosive steel tube refers to through anticorrosion process processed, can effectively prevent or slow down in transport
Chemistry or the steel pipe of electrochemical reaction generation corrosion phenomenon is there is during using.Existing
Anti-corrosive steel tube mostly be the surfaces externally and internally anticorrosion with painting coating at steel pipe, but to not using flange
Or for the large-diameter steel pipe of other connector connection, two steel-pipe weldings when, due to
Welding heating, can destroy the anticorrosion structure around weld seam, thus shorten the use of anti-corrosive steel tube
Life-span；It addition, after having welded, also manually to creep into the inwall of butt welded seam in steel pipe and carry out
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
Reasonable, increase the service life, save manpower, improves welding efficiency, the convenient liner operated not
The heavy caliber anti-corrosive steel tube of rust steel loop.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of heavy caliber anti-corrosive steel tube of inner liner stainless steel ring, including anti-corrosive steel tube body, its feature
It is: also include stainless steel ring, the two ends inwall of described anti-corrosive steel tube body is lined with rustless steel
Ring, described stainless steel ring is by inner bushing ring, external bushing ring and strengthens ventilative Concha Arcae and constitutes, inner bushing ring with
External bushing ring is arranged concentrically, and is provided with a circle and strengthens ventilative Concha Arcae between inner bushing ring and external bushing ring, should
Stainless steel ring is integrally forming with anti-corrosive steel tube body by pressurization, heating.
And, the wall thickness of described anti-corrosive steel tube body is 80-150mm, the wall of stainless steel ring after pressurization
Thickness is 8-15mm.
Advantage of the present utility model and good effect be:
1. the heavy caliber anti-corrosive steel tube of this inner liner stainless steel ring, by the two ends of original anti-corrosive steel tube
Lining stainless steel ring, does not so just worry because temperature is too high steel pipe inner wall welding when
Corrosion-inhibiting coating damages, and meanwhile, this most novel stainless steel ring is that built-in reinforcement is breathed freely the knot of Concha Arcae
Structure, the breathe freely setting of Concha Arcae of this reinforcement not only plays the effect of reinforcement, and, also can to welding time
Produced heat disperses, it is to avoid anti-corrosive steel tube and the deformation of stainless steel ring.
2. this utility model scientific structure design is reasonable, has and increases the service life, saves manpower, carries
High welding efficiency, the advantage of convenient operation, be a kind of inner liner stainless steel ring with higher innovation
Heavy caliber anti-corrosive steel tube.
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:

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.
A kind of heavy caliber anti-corrosive steel tube of inner liner stainless steel ring, including anti-corrosive steel tube body 1, its feature
It is: also include stainless steel ring 2, the two ends inwall of described anti-corrosive steel tube body is lined with rustless steel
Ring, described stainless steel ring is made up of the ventilative Concha Arcae 4 of inner bushing ring 5, external bushing ring 3 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 anti-corrosive steel tube body by pressurization, heating.
The wall thickness of described anti-corrosive steel tube body is 80-150mm, and after pressurization, the wall thickness of stainless steel ring is
8-15mm。
This utility model is by the two ends inner liner stainless steel ring at original anti-corrosive steel tube, so in welding
When just do not worry because temperature is too high, the corrosion-inhibiting coating of steel pipe inner wall being damaged, meanwhile,
This most novel stainless steel ring is that built-in reinforcement is breathed freely the structure of Concha Arcae, and this reinforcement is breathed freely the setting of Concha Arcae
Not only play the effect of reinforcement, and, also produced heat during welding can be disperseed, keep away
Exempt from the deformation of anti-corrosive steel tube and 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.
Claims (2)
1. a heavy caliber anti-corrosive steel tube for inner liner stainless steel ring, including anti-corrosive steel tube body, it is special
