The beneficial effects of the utility model are:

1, planform of the present utility model can meet fully contacting of any alloy surface and crude oil, and does not produce obvious resistance to the flowing of crude oil, is applicable to pumpingh well, flowing well and ground crude oil transportation system;

2. the utility model changes wax electronic structure of molecule by electrochemical action and then changes the reunion behavior of wax crystalline substance, effective suppression and slow down wax condense into block, the wax of precipitation is impelled to float on a liquid with tiny crystals form and with liquid flow, therefore effectively prevent and delay the condensation of wax on tube wall, sucker rod, thus extending the clean-out service cycle of oil well;

The unidirectional solid solution high-entropy alloy that the crystal grain that the interior pipe A of 3.A assembly is made up of the element of multiple electrode potential difference is tiny, also adds precious metals ag and rare earth element, increases galvanic interaction effect, enhances the electro-chemical activity of alloy.The external surface of described interior pipe B and the inner surface of outer tube B of B assembly scribble the very tiny nanocrystalline alloy coating of crystal grain, there is catalysis, enhance the electro-chemical activity of the special alloy of A assembly, the former oil viscosity of effective reduction, reduce paraffin point, prevent condensation and the precipitation of paraffin in crude oil;

4. outer tube A and outer tube B adds some equally distributed solder joints with oil connection A and oil connection B connecting portion respectively, and effectively prevent because crude oil constantly impacts for a long time, the connecting thread of outer tube and oil connection not easily loosens.
