Some stainless steels are sensitized by lousy warmth cure or welding, pickling with HNO & HF may bring about intergranular corrosion, and cracks caused by intergranular corrosion may well condense halides during operation, throughout cleansing, or for the duration of subsequent processing, causing Stress corrosion.
With the development of hydraulic know-how along with the escalating prerequisites for process cleanliness, the cyclic pickling system can demonstrate considerable benefits. For instance, the pickling pace is rapidly and the outcome is sweet; no large acid tanks and special workshops are necessary; the pipelines are continuously disassembled and transported, the piping cycle is shortened, and the possibility of re-contamination and re-rusting in the pipelines is lessened; Welded connections minimize flanges, joints, bolts, and so on.
