MOST IMPORTANT Points to be Noted before undertaking PICKLING and PASSIVATION of SS 304 316L : Perform the process in areas open to sky or well VENTILATED AREAS.... Designation: A380 – 06 Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment, and Systems1 This standard is issued under the ﬁxed designation A380; the number immediately following the designation indicates the year of
Pickling and Passivating of Welded Carbon Steel Pipes
The degreasing, cleaning and passivation process ensures that the internal surface of the vessel/equipment, and the ‘tie-in welds’ for high purity systems, is free from any organic contaminants and iron compound in the form of gas, oil, residues, or dirt resulting from the fabrication process. embossing dies for metal design pdf Passivation has also come to mean a surface cleaning operation with nitric acid, especially to dissolve iron contamination from the surface of stainless steels.

Acid pickling and passivation products are safe to use provided proper procedures are followed. Please ensure the safety precautions in the leaflet with the product are followed.
- Pickling and Passivation Stainless steel can corrode in service if there is contamination of the surface. Both pickling and passivation are chemical treatments applied to the surface of stainless steel to remove contaminants
- PROCEDURE FOR PICKLING AND PASSIVATION ACC. TO ASTM A 380 EQPT. NO. :- Work Order NO. Client Reference / Specification: Specification No.:Q 01-F 37 Austenitic and High Alloy Steel Pressure Vessels – Fabrication. Approved Equipments Inspection & Test Plan Purpose : This practice is applicable to Austenitic Stainless Steel (300 series
- Pickling (or Chemical Descaling) is done to remove scale and to clean the part before the passivation process takes place. The passivating of stainless steel is a post fabrication process with the end goal of making the surface more passive and corrosion resistant by restoring the surface to the original characteristics with protective oxide film.
- chromed layer underneath, a pickling is required – or a gentle grinding followed by a passivation. Decontamination ("Stainless steel and corrosion", Chapter 12.3) Literally, decontamination means de-poisoning, and that is exactly what is happening.
