Petromat is one among the most important Manufacturer, Supplier and Exporter of Alloy 20 Flanges in India. It’s well appropriate to the manufacture of explosives, gasoline, solvents, organic and inorganic chemicals, synthetic, pharmaceuticals, and food materials. Usual applications of those Alloy 20 Flanges include tanks, piping, pumps, valves and heats exchangers. Alloy UNS N08020 Flanges covers stabilization or niobium in contradiction of sensitization that eventually leads to intergranular corrosion. Alloy 20 Flanges is formed up from an iron-nickel-chromium mixture within the company of getting an accumulation of copper and molybdenum in it. WNR 2.4660 Flanges are accessible to our valuable customers in several ranges of diameters, wall thicknesses and sizes at quite affordable rates. We are having decades of experience in Supplying and Exporting Alloy 20 Pipe Flanges to vary countries like Iran, Iraq, Qatar, Oman, Jordan.

Alloy 20 Flanges is a nickel, iron, chromium, molybdenum, and copper alloy. Typically, nickel makes up approximately 30% of its composition, with iron being found in equal if not greater amounts. This provides corrosion resistance, and specifically resistance from chloride stress cracking. Alloy 20 Slip-on Flanges is practically resistant to chlorine and was designed to be utilized in sulfuric environments. It’s commonly applied in acidic and/or corrosive environments, like people who contain phosphoric and aqua forts. Alloy 20 Blind Pipe Flanges has proven to be excellent under corrosive conditions and various sorts of media. As a result, it’s commonly found in processing applications—such as food, or chemicals—along with pharmaceutical storage and processing.
