Description
Technical field
The technical field of anticorrosion of multiple tube is the utility model is related to, especially a kind of anticorrosion composite pipe.
Background technology
Plastic pipe is since light-weight, corrosion-resistant, shock resistance and tensile strength are good, friction coefficient is small, fluid resistance is small, peace
The advantages that facilitating is filled, is widely used in various production fields, development is swift and violent, but the structure of plastic pipe is not firm enough, and steel
Pipe can overcome disadvantages mentioned above, but steel pipe is due to the property of material itself, there are it is perishable, easily get rusty the problems such as, therefore in recent years
To there is a kind of new multiple tube.
But existing multiple tube is generally to non-oxidizing acid under room temperature (such as hydrochloric acid, dilute sulfuric acid, hydrofluoric acid), dust technology, alkali
There is good corrosion resistance with salting liquid, but since liquid easily produces line clogging in pipeline flow process, cause liquid
It is longer in pipeline residence time, the time of contact of liquid and pipeline is considerably increased, extra corrosion is generated, causes pipeline
Service life substantially reduces.
Utility model content
The technical problems to be solved in the utility model is：Easily produced in pipeline flow process to solve existing liquid
Raw line clogging, causes liquid longer in pipeline residence time, considerably increases the time of contact of liquid and pipeline, generate
Extra corrosion, causes pipeline service life to substantially reduce problem, the utility model provides a kind of anticorrosion composite pipe, corrosion-resistant
The radius at the round exit end of pipe is more than the radius of circular input end, and steel pipe is the structure being adapted with corrosion-resistant pipe, works as liquid
When flowing in the duct, since import is small, outlet is big, it is not easy to produces blocking, accelerating liquid flowing, efficiently solves existing
Liquid easily produces line clogging in pipeline flow process, causes liquid longer in pipeline residence time, considerably increases
The time of contact of liquid and pipeline, generates extra corrosion, causes pipeline service life to substantially reduce problem.
Technical solution is used by the utility model solves its technical problem：
A kind of anticorrosion composite pipe, including corrosion-resistant pipe and the steel pipe being located at outside corrosion-resistant pipe, the corrosion-resistant pipe is including justifying
Shape input end, round exit end and the connection supervisor at the circular input end of connection and round exit end, the round exit end
Radius is more than the radius of the circular input end, and the steel pipe is the structure being adapted with the corrosion-resistant pipe.
Further, the end of the steel pipe is stretched out at the round exit end.
Further, the length that the end of the steel pipe is stretched out at the round exit end is 0.5-2mm.
Further, the radius at the round exit end is more than the radius 5-30mm of the circular input end.
Further, the corrosion-resistant pipe is polyethylene pipe or polyvinyl chloride pipe.
Further, the steel pipe both ends are respectively provided with the input end connecting flange of convenient fixation and the port of export connects
Acting flange.
Further, as the design at round exit end, the circle input end stretches out the end of the steel pipe, described
The length that circular input end stretches out the end of the steel pipe is 0.5-2mm.
The beneficial effects of the utility model are：
（1）The utility model provides a kind of anticorrosion composite pipe, and the radius at the round exit end of corrosion-resistant pipe is more than circle
The radius of input end, steel pipe are the structure being adapted with corrosion-resistant pipe, when liquid flows in the duct, since import is small, are gone out
Mouth is big, it is not easy to produces blocking, accelerating liquid flowing, efficiently solves existing liquid and easily produced in pipeline flow process
Line clogging, causes liquid longer in pipeline residence time, considerably increases the time of contact of liquid and pipeline, generate volume
Outer corrosion, causes pipeline service life to substantially reduce problem；
（2）Circular input end stretches out the end of steel pipe, and the length that circular input end stretches out the end of steel pipe is 0.5-2mm,
When so carrying out flange fixation, will not be because of mismachining tolerance the problem of, cause to be unable to gluing, sealing between two corrosion-resistant pipes
Problem.If that is the end of corrosion-resistant pipe and the end of steel pipe flush, when mismachining tolerance occurs in steel pipe, somewhat than resistance to
Corrosion pipe highlights a bit, at this time after mounting flange, although steel pipe fits closely, occurs gap between corrosion-resistant pipe.
（3）The radius at round exit end is more than the radius 5-30mm of circular input end, test proves that, it will not produce stifled
Plug, and effect is preferable.
