Abstract
The utility model relates to a nonrust steel pipe of wear -resisting type of multilayer, this nonrust steel pipe are hollow body, and open at the body center has hollow groove, and the body includes interior body and outer body, and the internal portion of outer tube is located to interior body, and the internal coating of inner tube has heat -resisting anticorrosive layer, and the coating of the external portion of outer tube has the wearing layer, and the wearing layer surface is equipped with with the wear -resisting rib of the enhancement of circumferencial direction. Compared with the prior art, the utility model has following advantage: overall structure is simple, and the manufacture craft is simple and convenient, has certain heat -resisting anti -corrosion performance, has strengthened the intensity of body, has strengthened the abrasive resistanc, has prolonged life, has practiced thrift the cost.
Description
Technical field
The utility model relates to a kind of multi-layer wear-resistant type Stainless Steel Tube, belongs to stainless steel technical field.
Background technique
Stainless steel refers to the steel of the chemical etching dielectric corrosions such as the weak aggressive medium such as resistance to air, steam, water and acid, alkali, salt, also known as Stainless Acid Resistant Steel.Stainless corrosion resistance depends on alloying element contained in steel.The basic alloying element of stainless steel also has nickel, molybdenum, titanium, niobium, copper, nitrogen etc., to meet the requirement of various uses to stainless steel structure and properties.Stainless steel is easily by chloride ion corrosion, because chromium, nickel, chlorine are coordination essences, coordination essence can carry out exchange assimilation thus form stainless corrosion.Although stainless steel has performance characteristics that is corrosion-resistant, high strength, general stainless steel have been grown and also can get rusty service time, be particularly applied in fluid-transporting tubing, and outer surface easily wear phenomenon occurs.
Therefore, a kind of new technological scheme should be provided to solve the problem.
Summary of the invention
The utility model provides a kind of multi-layer wear-resistant type Stainless Steel Tube.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of multi-layer wear-resistant type Stainless Steel Tube, this Stainless Steel Tube is the body of hollow, body central has groove, body comprises interior tube body and outer tube body, interior tube body is located at outer tube body inside, be coated with heat-resistant anticorrosion layer in interior tube body, outer tube body is externally coated with wearing layer, and wearing layer outer surface is provided with the wear-resisting rib of reinforcement of same circumferencial direction.
The related content of technique scheme is explained as follows:
In technique scheme, interior tube body is steel body, and outer tube body is stainless steel body.
Further technological scheme, interior tube body and outer tube body are stainless steel body.
Preferably, heat-resistant anticorrosion layer is polytetrafluoroethylene floor, and wearing layer is silicon nitride layer.
Preferably, interior tube body and outer tube body are weldless tube or welded pipe.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Overall structure is simple, and preparation process is easy, has certain heat-resistant anticorrosion performance, enhances the intensity of body, enhance abrasive resistance, extend working life, saved cost.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model schematic diagram.
In above accompanying drawing: 1, groove; 2, interior tube body; 3, outer tube body; 4, heat-resistant anticorrosion layer; 5, wearing layer; 6, wear-resisting rib is strengthened.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, of the present utility model kind of multi-layer wear-resistant type Stainless Steel Tube, this Stainless Steel Tube is the body of hollow, body central has groove 1, body comprises interior tube body 2 and outer tube body 3, it is inner that interior tube body 2 is located at outer tube body 3, interior tube body 2 and outer tube body 3 are weldless tube or welded pipe, interior tube body 2 is steel body, outer tube body 3 is stainless steel body, (or interior tube body 2 and outer tube body 3 be stainless steel body), heat-resistant anticorrosion layer 4 is coated with in interior tube body 2, outer tube body 3 is externally coated with wearing layer 5, heat-resistant anticorrosion layer 4 is polytetrafluoroethylene floor, wearing layer 5 is silicon nitride layer, wearing layer 5 outer surface is provided with the wear-resisting rib 6 of reinforcement of same circumferencial direction, strengthening wear-resisting rib 6 is arc shape or other shape, overall structure is simple, preparation process is easy, there is certain heat-resistant anticorrosion performance, enhance the intensity of body, enhance abrasive resistance, extend working life, save cost.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
