Description
Technical field
This utility model belongs to rustless steel technical field, and in particular to a kind of anticorrosion special stainless steel pipe.
Background technology
Rustless steel (Stainless Steel) is the abbreviation of stainless acid resistant steel, the weak corrosive medium such as resistance to air, steam, water
Or the steel grade with rustless property is referred to as rustless steel；And the steel grade for corroding in resistance to chemical attack medium (chemical etching such as acid, alkali, salt)
Referred to as acid resisting steel.Make their corrosion resistance different due to both differences in chemical composition, common stainless steel typically intolerant to
Chemical mediator corrodes, and acid resisting steel then generally individually has rustless property.Stainless invention and use, to trace back to the first time world
Great War period.British scientist Henry BLAZERs profit is studied the improvement of weapon by the commission of munitions factory of army headquaters of British government.
At that time, the rifle bore of soldier easily weares and teares, and BLAZER profit thinks a kind of nonabradable steel alloy of invention." rustless steel " one word
Not exclusively refer to a kind of rustless steel merely, but represent that more than 100 plant industrial rustless steel, the every kind of stainless steel capital developed is at it
Specific application has good performance.Successfully key is to understand fully purposes first, and correct steel grade is then determined again.
Generally only six kinds of the steel grade relevant with Architectural Construction application., all containing 17～22% chromium, preferable steel grade is also for they
Containing nickel.Addition molybdenum can further improve the corrosion of atmospheric corrosiveness, the particularly air of resistance to chloride.Rustless steel is often by tissue
State is divided into：Martensite steel, ferritic steel, austenitic steel, austenite-ferrite (two-phase) rustless steel and precipitation-hardening stainless steel
Deng.In addition, can be divided into by composition：Straight-chromiun stainless steel, chromium nickel stainless steel and chromic manganese nitrogen stainless steel etc..Rustless steel steel tubes be except
The general name of the steel pipe of other cross sectional shapes beyond pipe, there is welding shape tube and seamless heterotype pipe.Because the relation of material, no
It is many, 200,201 material hardness high wind that rust steel shape tube is generally more than 304 materials, and molding difficulty is increased.Rustless steel shape tube
Usually generally can be divided into come what is distinguished according to disconnected section, global shape：Oval steel tubes, triangle steel tubes, six
Angular steel tubes, rhombus steel tubes, rustless steel pattern pipe, the U-shaped steel pipe of rustless steel, heat absorption plate core structure, stainless steel elbow, S bend pipe are curved
Pipe, octagonal steel tubes, semicircle deformed steel circle, inequilateral hexagon steel tubes, five lobes are quincunx steel tubes, biconvex
Shape steel tubes, double concave steel tubes, Semen Benincasae shape steel tubes, conical steel tubes, corrugated steel tubes etc..But
Existing special stainless steel pipe mostly anticorrosion effect is bad, so allows for service life reduction, and frequently changing makes
Increased with cost, and existing special stainless steel pipe use environment is single, it is impossible to it is enough to be suitable for different environment well, so
We need a Novel special-shaped stainless steel tube to solve the above problems to meet the demand of people.
Utility model content
The purpose of this utility model is to provide a kind of anticorrosion special stainless steel pipe, to solve above-mentioned background technology in carry
The problem for going out.
For achieving the above object, this utility model provides following technical scheme：A kind of anticorrosion special stainless steel pipe, including
Stainless steel tube body, external anti-corrosion layer, drying layer, spiral anticorrosive coat, borded pile, polishing layer, interior anticorrosive coat, the borded pile is fixed
On the top of stainless steel tube body, the spiral anticorrosive coat is arranged on the surface of borded pile, and the interior anticorrosive coat is arranged on stainless
The inner side of steel pipe body, the polishing layer is fixed on the inner side of interior anticorrosive coat, and the external anti-corrosion layer is fixed on stainless steel tube body
Outside, the drying layer is arranged on the surface of external anti-corrosion layer.
Preferably, the interior anticorrosive coat and external anti-corrosion layer are disposed as acid-resistant anti-corrosion layer.
Preferably, it is provided with desiccant inside the drying layer.
Preferably, the stainless steel tube body is internally threaded, and borded pile is by screw thread and stainless steel tube body
Rotate connection.
Technique effect of the present utility model and advantage：The anticorrosion special stainless steel tubular construction is simple, easy to use, and
Low cost, anticorrosion ability more preferably, is suitable for more environment；The setting of external anti-corrosion layer and interior anticorrosive coat can double shielding this not
Rust steel pipe body is not corroded so that the stainless steel tube body use time is longer, so as to cost-effective；The setting energy of drying layer
The corrosion of outside rainwater is enough prevented well, further prevents stainless steel tube body to be corroded, improve etch-proof protection effect
Really；The setting of detachable borded pile can enable to the anticorrosion special stainless steel pipe and be suitable for different working environments, convenient
The use of people.
