Description
Technical field
Metal tube technical field is the utility model is related to, more particularly to a kind of corrosion resistant metal tube.
Background technology
Metal pipe material currently on the market is largely single material, in order to meet the requirements such as intensity or anti-corrosion,
Needing increases thickness considerably increases the cost of engineering to reach requirement.But increase the thickness of tubing anyway,
All the time still there is the problem of anti-corrosion capability difference in the tubing based on iron-based (carbon steel), easily by acid, alkali, air of environment etc.
The corrosion of medium, it is necessary to provide one kind for this more resistant to corrosion, and prepares the metal pipe material of cost.
The content of the invention
The purpose of this utility model be exactly in order to which the one kind for solving the deficiency of prior art and providing is not only simple in structure, and
And it is reasonable in design, production efficiency is high, prepares the low corrosion resistant stainless steel tube of cost.
The utility model is to realize above-mentioned purpose using following technical solution：A kind of corrosion resistant stainless steel tube,
Characterized in that, it includes metal inner pipe and around the stainless strip being located on metal inner pipe, stainless strip is along metal
The axial direction screw winding of pipe forms, and is connected as a single entity in a welding manner between adjacent two circle stainless strips, in metal
Inside pipe wall is provided with the helical form stainless steel layer formed by axial direction winding of the stainless strip along metal inner pipe.
As a further illustration of the above scheme, two layers or more than two layers of stainless strip is arranged with metal inner pipe,
The end of two layers or more than two layers of stainless strip is welded as a whole.
Further, the side of the metal inner pipe is provided with the convex tendon set around central shaft spiral, in axial direction
Two adjacent sections convex tendon between form the recess of accommodating stainless strip, innermost layer stainless strip is arranged in recess, outer layer
Stainless strip be wrapped in outside innermost layer stainless strip and convex tendon.
Further, the metal inner pipe is carbon steel tubing.
The beneficial effect that the utility model can be reached using above-mentioned technical solution is：
1st, the utility model sets helical form stainless steel using carbon steel tubing as metal inner pipe in metal inner pipe internal layer
Layer, outer layer winding stainless strip, solve thes problems, such as that existing metallic conduit is not corrosion-resistant, and production cost is low, should
It is wide with scope, it can be applied to the fields such as engineering pipeline, civilian household pipe.
2nd, the utility model sets the convex tendon set around central shaft spiral in the side of metal inner pipe so that side vertically
To two adjacent sections convex tendon between form the recess of accommodating stainless strip, innermost layer stainless strip can be arranged on recess
It is interior, avoid falling off around the stainless strip being located at outside metal inner pipe, stability is more preferable.
Brief description of the drawings
Fig. 1 is cross section structure diagram of the present utility model；
Fig. 2 is structural representation of the present utility model.
Description of reference numerals：1st, metal inner pipe 2, stainless strip 2-1, innermost layer stainless strip 2-2, outer layer
Stainless strip 3, convex tendon 4, groove 5, helical form stainless steel layer.
Embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
As Figure 1-Figure 2, the utility model be a kind of corrosion resistant stainless steel tube it include metal inner pipe 1 and around being located at
Stainless strip 2 on metal inner pipe, the metal inner pipe are carbon steel tubing.Stainless strip 2 is along the axial direction of metal inner pipe 1
Direction screw winding forms, and is connected as a single entity in a welding manner between adjacent two circle stainless strips 2, the inwall of metal inner pipe 1
It is provided with the helical form stainless steel layer 5 formed by axial direction winding of the stainless strip along metal inner pipe.
Further, two layers of stainless strip 2, the end welding of two layers of stainless strip are arranged with metal inner pipe
It is integrated.The side of metal inner pipe is provided with the convex tendon 3 set around central shaft spiral, two adjacent sections convex tendon in axial direction
Between form the recess 4 of accommodating stainless strip, innermost layer stainless strip 2-1 is arranged in recess, the stainless steel band of outer layer
Material 2-2 is wrapped in outside innermost layer stainless strip and convex tendon.
The utility model compared with prior art, 1, using carbon steel tubing as metal inner pipe, set in metal inner pipe internal layer
Helical form stainless steel layer is put, outer layer winding stainless strip, solve thes problems, such as that existing metallic conduit is not corrosion-resistant, and
Production cost is low, has a wide range of application, and can be applied to the fields such as engineering pipeline, civilian household pipe；2nd, in the side of metal inner pipe
The convex tendon set around central shaft spiral is set so that accommodating stainless steel band is formed between two adjacent sections convex tendon in axial direction
The recess of material, innermost layer stainless strip can be arranged in recess, avoided around the stainless strip hair being located at outside metal inner pipe
Life comes off, and stability is more preferable.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
