Metals and alloys have been used for a long time to manufacture various components of a piping system. Flange being one of them. Alloy 20 Flanges is one such type of flange that is suitable for fabrication and has good mechanical strength. Incoloy 20 Slip On Flanges manufacturer In India recommends these flanges as they are resistant to phosphoric and nitric acid. Nickel Alloy 20 Blind Flanges can also be used in sulfuric acid that is boiling 20% to 40%. ASTM B366 UNS N08020 Weld Neck Flange is also resistant to local corrosion such as crevice and pitting. They resist corrosion even in severe environments.
Werkstoff Nr. 2.4660 Socket Weld Flange is used in petrochemical plants, mixing tanks, and pickling equipment. Furthermore, these ASME B366 Alloy N08020 Lap Joint Flanges are also used in chemical plants, heat exchangers, dye industries, and food processing industries. They work smoothly in boiling water as well as in sub zero or cryogenic temperatures. Carpenter 20 Stainless Steel Plate Flange displays resistance to cracking and has high density. Alloy 20 Pipe Flanges are also resistant to acid solutions such as sulfuric, phosphoric, and nitric.
These Nickel Alloy 20® Raised Face Flanges have the element niobium added to them in trace amounts that minimize the carbide precipitation caused during welding and also stabilize the flanges. Incoloy 3.7165 Threaded Flanges offer good fabricability, and machinability this makes them useful in the dye production industry and pharmaceutical industry. We have been manufacturing these ASTM B366 Alloy 20 (N08020) RTJ Flanges using high quality raw material and have been supplying them to our customers at affordable rates. Out timely delivery and assured quality of the product has gained us the reputation that we have today in the market.
