Abstract
The utility model provides a high -strength steel pipe, including the steel pipe body, the body includes from interior first steel pipe and second steel pipe to outer range, the inner wall of first steel pipe is opened there is helical shape drainage groove, the cell wall in drainage groove scribbles one deck anti -corrosion coating, it has the graphite layer to fill between first steel pipe and the second steel pipe, second steel pipe surface is equipped with the strengthening rib, the strengthening rib outside is equipped with the protection tube, the body both ends are fixed with flange. The setting of high -strength steel pipe through spiral drainage groove can make liquid take place small rotation when flowing through the body, reduce the deposit of impurity, the anti -corrosion coating of drainage inslot can avoid the corruption of body, the intensity that sets up multiplicable steel pipe of graphite layer and strengthening rib increases the bearing capacity of steel pipe, has improved the life of steel pipe.
Description
Technical field
The utility model belongs to steel pipe field, especially relates to a kind of High Tensile Steel Tube.
Background technique
Steel pipe is widely used in various conveyance conduit and building framework because it is economical and practical, and steel pipe, because of its severe working environment, corrosion and distortion very easily occurs, thus reduces the working life of steel pipe, not only cause very large loss, and affects normal use.
Summary of the invention
In view of this, the utility model is intended to propose high, the etch-proof High Tensile Steel Tube of a kind of intensity.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of High Tensile Steel Tube; comprise steel pipe body; described body comprises the first steel pipe and the second steel pipe that arrange from the inside to the outside; the inwall of described first steel pipe has spiral drainage trough; the cell wall of described drainage trough scribbles one deck corrosion-resistant coating, is filled with graphite layer between described first steel pipe and the second steel pipe, and described second outer surface of steel tube is provided with stiffening rib; be provided with protective tube outside described stiffening rib, described body two ends are fixed with adpting flange.
Further, described flange is the boss be made up of small one and large one two hollow cylindrical platforms, and described small cylindrical decometer is on the inwall of described first steel pipe, and described great circle cylindricality platform and described protective tube weld together.
Further, described flange is corrosion protection flange.
Further, described stiffening rib is that Stainless Steel Wire spiral winding forms.
Relative to prior art, High Tensile Steel Tube described in the utility model has following advantage: in this programme, the setting of spiral drainage trough can make liquid that small rotation occurs when flowing through body, reduce the deposition of impurity, corrosion-resistant coating in drainage trough can avoid the corrosion of body, the setting of graphite layer and stiffening rib can increase the intensity of steel pipe, increase the bearing capacity of steel pipe, improve the working life of steel pipe.
