surface condition of the material and the heat input during welding. This situation is illustrated in Figure 3. The figure shows two series of tests involving TIG orbital welding of stainless steel pipes that differ in terms of wall thickness and material. It illustrates clearly that the formation of temper colours differsPickling and passivating of metals | Vecom GroupPickling and passivating removes welding discoloration, annealing skin, foreign iron, restores corrosion resistance and brings it back to the original level of the base material. Pickling can be carried out in various ways, depending on the size and construction of the object or part to be treated: Immerse in, or circulate with a pickling liquid;Pickling & Passivation Services On-Site & Shop | Astro PakBoth pickling and passivation are chemical processes that are utilized to provide protection to metals against corrosion and pitting. In either process, an acidic solution is applied to the metal surface to remove contaminants and to aid in the formation of a continuous, chromium-oxide passive film. Without pickling and/or passivation, stainless steel is subject to corrosion in service which can lead to costly quality issues.See more on astropak high level welding stainless steel pipe Surface treatment
Keeping stainless steels stainless - The Fabricator
Stainless steel's corrosion resistance is due to a thin, chromium-rich, transparent oxide film on the surface1. This protective film develops when more than 10.5 percent of chromium is present in the alloy and when the gas or liquid environment the stainless steel is exposed to provides oxygen to its surface. Under these conditions, the surface is passive, or resistant to corrosion. Failure to develop and maintain this passive film renders the surface active, or possessing corrosion resistance similar to conventional sSee more on thefabricator high level welding stainless steel pipe Surface treatmentEstimated Reading Time: 9 minsInternal corrosion 304L SS with domestic (drinking) water high level welding stainless steel pipe Surface treatmentJul 17, 2008 · My company has been using 304L Stainless Steel piping for domestic water service for approximately 10 years now.
