Spiral welded pipe pickling is one among several helpful steel pipe anti-corrosion treatments. Spiral welded pipe pickling is to any take away oil on steel pipe surface, and by victimisation weak phosphate resolution (acid concentration 100% ~ 75%) to scrub the surface of spiral welded pipe, thus to succeed in to purpose of chloride content on the surface of the SSAW steel pipe is not up to a pair of alphabetic character g/cm2, at constant time that spiral welded pipe anti-corrosion surface chemical and chemistry reaction, during this method, phosphate chemical conversion coating formatted. the most result of conversion film is: give matrix metal protection, to some extent, stop metal corrosion; Improve the corrosion resistant ability of coating; Strengthen the binding force between the coating and artifacts.


Pickling may be a quite effective methodology in spiral welded pipe three alphabetic character anti-corrosive, improve the corrosion resistance and uncovering resistance coating layer. Spiral welded pipe industrial plant within the same production method, all initial external anti-corrosion, inner anti-corrosion once. Workshop layout is often affordable, the inner and external anti-corrosion workshop is closely joined, to cut back the lifting or any further movement, and therefore the workshop area is larger, the external anti-corrosion technology adopts double shot blasting, pickling, salt treatment and separate the escape detection method, however there's no strict inner anti-corrosion production method.
