Pipe can overcome disadvantages mentioned above, but steel pipe has the problems such as perishable, easily to get rusty due to the property of material itself, therefore in recent years
To there is a kind of new multiple tube.
But existing multiple tube is typically to non-oxidizing acid under normal temperature (such as hydrochloric acid, dilute sulfuric acid, hydrofluoric acid), dust technology, alkali
There is good corrosion resistance with salting liquid, but because liquid is also easy to produce heat in flow process, greatly promote fluid temperature,
The corrosion resistance of plastic tube is greatly reduced when the temperature increases, and the service life of plastic tube is greatly limited.
The content of the invention
The technical problem to be solved in the present invention is：In order to solve existing multiple tube, its corrosion resistance is big when the temperature increases
Big to decline, the service life of multiple tube is greatly limited problem, and the invention provides a kind of anti-with cooling effect
Rotten multiple tube, is additionally provided with the cooling tube for cooling down between corrosion-resistant pipe and steel pipe, cooling tube and corrosion-resistant pipe it
Between be provided with and be used to inject the first clearance portion of cold air, by the continuous injection of cold air, absorb the heat of liquid, drop significantly
Low fluid temperature, improves the corrosion resistance of multiple tube, efficiently solves existing multiple tube its corrosion resistant when the temperature increases
Corrosion is greatly reduced, and the service life of multiple tube is greatly limited problem.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of anticorrosion composite pipe with cooling effect, including corrosion-resistant pipe and the steel pipe being located at outside corrosion-resistant pipe, the corrosion resistant
