Abstract
The utility model relates to an antirot l steel pipe, which comprises a PP-R outer pipe(1), a PP-R inner pipe(2) and a steel pipe(3). The PP-R outer pipe(1) is arranged on the outer wall of the steel pipe(3), while the PP-R inner pipe(2) is arranged on the outer wall of the steel pipe(3). As the steel pipe(3) is arranged between the PP-R outer pipe(1) and the PP-R inner pipe(2), oxidization, corrosion, aging and water leakage phenomenon will not take place and the water resource will not be wasted. When the utility model needs to be connected, only the PP-R pipe fitting hot melt welding machine is applied to fuse the PP-R outer pipe(1) and PP-R inner pipe(2), which is completed within ten seconds and will not form scale and has a long service life.
Description
Affiliated technical field
The utility model relates to a kind of steel pipe, especially relates to a kind of anti-corrosive steel tube.
Background technique
At present, the water-feeding pipes that China generally uses has two kinds of steel pipe and PP-R tubing, steel pipe is owing to its hardness height is widely applied in water system and the hot-water heating installation, but this tubing is installed inconvenient, and it is perishable, particularly being buried makes moist after underground very easily gets rusty agingly, water leakage phenomenon occurs, causes the great lot of water resources waste; Though PP-R tubing antiseptic property is good, in light weight, easy for installation, this tubing hardness is not high, particularly does when the station pipe uses and is easy to fracture, water leakage phenomenon occurs, can cause water resource waste yet.
Summary of the invention
In order to solve the deficiency that steel pipe is perishable, PP-R tubing hardness is low, the utility model provides a kind of anti-corrosive steel tube.This anti-corrosive steel tube organically combines steel pipe and PP-R tubing, and is promptly not perishable, also is not easy fracture, water leakage phenomenon can not occur, just can not cause the waste of water resources.
The technological scheme that its technical problem that solves the utility model adopts is: the PP-R outer tube is set on the outer wall of steel pipe, is provided with in the PP-R on the inwall of steel pipe and manages.
The beneficial effects of the utility model are: this anti-corrosive steel tube organically combines steel pipe and PP-R tubing, and promptly corrosion-resistant, easy-rupturing not can not cause the waste of water resources, health, easy for installation, and non-scaling again, long service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is a structural representation of the present utility model.
Pipe, 3. steel pipe in the 1.PP-R outer tube among the figure, 2.PP-R.
Embodiment
In accompanying drawing 1, anti-corrosive steel tube is made up of pipe (2) and steel pipe (3) in PP-R outer tube (1), the PP-R.PP-R outer tube (1) is set on the outer wall of steel pipe (3), pipe (2) in the PP-R is set on the inwall of steel pipe (3).Because steel pipe (3) is arranged in PP-R outer tube (1) and the PP-R and manages between (2), oxidation, burn into deterioration phenomenon can not occur, water leakage phenomenon can not occur, just can not cause the waste of water resources.When need connecting, the utility model only need can connect in tens of seconds and finish with pipe (2) in PP-R pipe part sweating welder hot melt PP-R outer tube (1) and the PP-R, and non-scaling, long service life.
Claims (1)
- A kind of anti-corrosive steel tube is made up of pipe (2) and steel pipe (3) in PP-R outer tube (1), the PP-R, it is characterized in that: PP-R outer tube (1) is set on the outer wall of steel pipe (3), pipe (2) in the PP-R is set on the inwall of steel pipe (3).
