Abstract
The invention discloses a kind of outer surface of steel tube derusting method, the outer surface of steel tube derusting method is comprised the following steps：A, by steel pipe clamping on whirler；B, compound concentration for 15-20% salt solution and be heated to 60-80 degrees Celsius；C, will heating salt solution pressurization after steel tube surface is sprayed to by shower nozzle；D, steel tube surface is purged using compressed air.A kind of outer surface of steel tube derusting method of the present invention, hydro-peening is carried out to rotating steel tube outer surface by using heating pressurization salt solution, outer surface of steel tube rust stain can fast and effectively be removed, steel tube surface is purged by compressed air again, also it can be cleaned and is dried, it is to avoid rust stain residual and floating rust are produced.
Description
Technical field
The present invention relates to a kind of steel pipe derusting method, more particularly to a kind of outer surface of steel tube derusting method.
Background technology
During steel pipe manufacture and use, it is often necessary to carry out processing of rust removing to its surface.The conventional method of steel tube surface rust cleaning is shot-peening, but its is less efficient and costly, and understands effect on driving birds is not good.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple to operate and lower-cost outer surface of steel tube derusting method.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of outer surface of steel tube derusting method, comprises the following steps：A, by steel pipe clamping on whirler；B, compound concentration for 15-20% salt solution and be heated to 60-80 degrees Celsius；C, will heating salt solution pressurization after steel tube surface is sprayed to by shower nozzle；D, steel tube surface is purged using compressed air.
Preferably, brine pressure is 5-7MPa in the step C.
Preferably, compressed air pressure is 2-4MPa in the step D.
Compared with prior art, a kind of outer surface of steel tube derusting method of the present invention, hydro-peening is carried out to rotating steel tube outer surface by using heating pressurization salt solution, outer surface of steel tube rust stain can fast and effectively be removed, steel tube surface is purged by compressed air again, also it can be cleaned and is dried, it is to avoid rust stain residual and floating rust are produced.
