The tubing of inner lining fluoroplastics
(1) technical field
The utility model relates to a kind of tubing.The link that is widely used in industry fed sheet of a media tubing such as oil, chemical industry, electric power, boats and ships, metallurgy, machinery, weaving, food, building.Metal conduit link technical field.
(2) background technique
At present, the material that is applied to the tubing of industry fed sheet of a media such as oil, chemical industry, electric power, boats and ships, metallurgy, machinery, weaving, food, building, pharmacy is 15CrMoR.This class tubing intensity height, withstand voltage properties is strong, but decay resistance a little less than, therefore can only be used for the conveying of general medium, and can not be used for conveying the corrosion-resistant medium that can have higher requirements.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of both had high strength, high withstand voltage properties are provided, and has the tubing of the inner lining fluoroplastics of decay resistance again.
The purpose of this utility model is achieved in that a kind of tubing of inner lining fluoroplastics, is composited by outer tube and internal lining pipe, and described outer tube material is 15CrMoR, and the internal lining pipe material is fluoroplastic.
The beneficial effects of the utility model are:
1, the utility model outer tube material adopts 15CrMoR, the intensity height, and withstand voltage properties is strong, therefore can guarantee the requirement of tubing to intensity and withstand voltage properties.
2, the utility model internal lining pipe material adopts fluoroplastic, and decay resistance is strong, therefore can guarantee the requirement of tubing to decay resistance.
