Product Description

For carbon steel pipe (CS pipe), it should be degreased first and then pickled, because grease is insoluble in acid solution. If pickling is performed first, neither the oil stains nor the rust covered by the oil stains can be removed.


Degreasing pickling method for carbon seamless steel pipe:

At present, the tank immersion method is often used in construction, and the liquid level exceeds the outer surface of the pipe by more than 50mm during immersion. Since the oxygen pipeline needs to be treated by degreasing, pickling and passivation, four tanks are generally made according to the actual diameter of the pipe used. That is, degreasing tank, pickling tank, neutralization tank, passivation tank. The oxygen pipeline degreasing and pickling process is: degreasing→water washing→pickling→water washing→neutralization→passivation→water washing→dr

 Degreasing

The formula of the degreasing solution is as follows: each liter of the solution contains 20g-30g of sodium hydroxide, 35g-50g of sodium nitrate, and 3g-5g of sodium silicate. The operating process requirements are: the liquid temperature is 70 ℃ ~ 80 ℃, the soaking time is determined by the test method according to the amount of oil on the surface of the pipe, generally about 10min ~ 40min. The heating method can be steam. Degreasing parts shall be inspected by any of the following methods. (1) Wipe the surface of the degreased part with clean and dry white filter paper, if there is no trace of grease on the paper, it is qualified. (2) Use 100% camphor below 1mm to check the condensate to flush the condensate, and it is qualified to keep rotating. (3) Check the surface of the degreasing part with ultraviolet rays with a wavelength of 3200-3800 angstroms, and the grease-free fluorescence is qualified. After degreasing treatment, the oil pollution on the pipe surface can be removed.
