Description
Technical field
The utility model is related to stainless steel tube technical field, specially a kind of novel stainless steel seamless steel tube.
Background technology
Stainless-steel seamless pipe is common metallurgical metal product, in the market applied to ships seawater pipeline, because of it
Special environmental requirement, it is necessary to possess preferable corrosion resistance, pitting corrosion resistance and stress resistance energy, although the steel pipe of common material
The basic demand of ships seawater pipeline can be substantially conformed to, but overall performance is unsatisfactory, easily produces spot corrosion and grain boundary corrosion,
Cause the reduction of steel pipe mechanical intensity and extension property so that steel pipe service life is shorter, while price is also costly.
Utility model content
The purpose of this utility model is to provide a kind of novel stainless steel seamless steel tube, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of novel stainless steel seamless steel tube, bag
Hollow steel tube body is included, the hollow steel tube inner body wall sets and is brought into close contact under acid-proof/impervious barrier, the acid-proof/impervious barrier
Have and reinforcement is also radially arranged in anticorrosive coat, the hollow steel tube inner body wall, the hollow steel tube outer body sets anti-impact
Layer is hit, the anti-impacting layer is orderly arranged outside each hollow overcoat, carbon foamed substrate heat-insulation layer, fiberglass enhancement layer, the glass
Wearing layer is set on the outside of glass steel enhancement layer.
It is preferred that, the acid-proof/impervious barrier is made up of high density polyethylene (HDPE) and low density polyethylene (LDPE)；The anticorrosive coat is by second
Alkene-acetate ethylene copolymer is made.
It is preferred that, the wearing layer uses the high chromium materials of GTCrMoNiCu.
It is preferred that, the anti-impacting layer uses 17CrNiMo carbon steel materials.
Compared with prior art, the beneficial effects of the utility model are：The utility model novel in structural design, it is wear-resisting, resistance to
Rotten, shock resistance is good, with higher mechanical strength and extensibility, extends the service life of steel pipe；Acid-proof/impervious barrier is set
Antiacid leakage performance can effectively be strengthened, the utility model is suitable for making ships seawater pipeline, is suitable in rugged environment
Under use.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of novel stainless steel seamless steel tube, including it is hollow
Steel pipe body 1, it is characterised in that：The inwall of hollow steel tube body 1 is set under acid-proof/impervious barrier 2, the acid-proof/impervious barrier 2
It is closely fitted with anticorrosive coat 3, the inwall of hollow steel tube body 1 and is also radially arranged reinforcement 4, the hollow steel tube body 1
Outside sets anti-impacting layer 5, and the anti-impacting layer 5 is orderly arranged outside each hollow overcoat 6, carbon foamed substrate heat-insulation layer 7, glass
Steel enhancement layer 8, the outside of fiberglass enhancement layer 8 sets wearing layer 9.The utility model novel in structural design, wear-resisting, corrosion resistant,
Shock resistance is good, with higher mechanical strength and extensibility, extends the service life of steel pipe.
In the present embodiment, acid-proof/impervious barrier 2 is made up of high density polyethylene (HDPE) and low density polyethylene (LDPE)；The anticorrosive coat 3 by
Ethylene-vinyl acetate copolymer is made.Anticorrosive coat has good flexibility, still is able at -50 DEG C with preferably flexible
Property, the transparency and lustrous surface it is good, chemical stability is good, the characteristic such as anti-aging intensity height；The utility model setting acid-proof/
Impervious barrier can effectively strengthen antiacid leakage performance, and the utility model is suitable for making ships seawater pipeline, is suitable for severe
In the environment of use.
In the present embodiment, wearing layer 9 uses the high chromium materials of GTCrMoNiCu；Anti-impacting layer 5 uses 17CrNiMo carbon steels
Material.The wearing layer and anti-impacting layer of setting, can further extend the service life of steel pipe.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
