Abstract
The utility model discloses a steel pipe with high intensive property, its steel pipe body that has stainless steel, the steel pipe body is hollow pipe, the outer wall plating of steel pipe body has the chromium nitride layer, the inside strengthening rib strip that is equipped with triangle -shaped of steel pipe body, the three top of strengthening rib strip is connected on the inner wall of steel pipe body, three limit middle parts of strengthening rib strip still are equipped with the enhancement rib that links to each other with steel pipe body inner wall. The steel pipe body is inside to be equipped with the strengthening rib strip and to strengthen the rib, can effectively improve the intensity of tubular product. The outer wall plating of steel pipe body has the chromium nitride layer. The chromium nitride layer has very high hardness, and the hard thing fish tail of difficult quilt does not rust, can keep the gloss on surface for a long time, prolongs the life of steel pipe.
Description
Technical field
The utility model relates to a kind of steel pipe with high strength properties.
Background technique
Hollow steel pipe compares solid steel pipe while having equivalent bending resistance twisting strength, and weight is lighter, but still there is the defect of insufficient strength, can not meet very well and use needs.
In addition, common stainless steel pipe in use, easily gets rusty, corrodes, and easily scratches the working life producing local defect and then greatly shorten steel pipe by hard object.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of steel pipe with high strength properties, its intensity is high, wear-resisting, corrosion-resistant.
Have a steel pipe for high strength properties, it has the steel pipe body of stainless steel, and described steel pipe body is hollow circular-tube, and the outer wall plating of described steel pipe body has chromium nitride layer; Described steel pipe body interior is provided with leg-of-mutton reinforced rib, and three tops of described reinforced rib are connected on the inwall of steel pipe body, is also provided with the reinforcement rib be connected with steel pipe inner body wall in the middle part of three limits of described reinforced rib.
The thickness of described chromium nitride layer is 0.1-0.2mm.
After adopting technique scheme, the utility model tool has the following advantages:
1, steel pipe body interior is provided with reinforced rib and strengthens rib, effectively can improve the intensity of tubing.
2, the outer wall plating of steel pipe body has chromium nitride layer.Chromium nitride layer has very high hardness, is not easily scratched by hard object, non-corrosive, can keep the gloss on surface for a long time, extends the working life of steel pipe.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present utility model.
Reference numeral illustrates:
Steel pipe body 1, chromium nitride layer 2, reinforcement rib 3, reinforced rib 4.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, a kind of steel pipe with high strength properties, it has the steel pipe body 1 of stainless steel, and steel pipe body 1 is hollow circular-tube, and the outer wall plating of steel pipe body 1 has chromium nitride layer 2, and the thickness of chromium nitride layer 2 is 0.1-0.2mm.
Steel pipe body 1 inside is provided with leg-of-mutton reinforced rib 4, and three tops of reinforced rib 4 are connected on the inwall of steel pipe body 1, is also provided with the reinforcement rib 3 be connected with steel pipe body 1 inwall in the middle part of three limits of reinforced rib 4.
Above, be only the utility model preferably embodiment, but protection domain of the present utility model is not limited thereto, protection domain of the present utility model should be as the criterion with the protection domain of claim.
Claims (2)
