Inconel 825 Flanges
UNS N08825 Flange, DIN 2.4858 Flanges
We are Manufacturer, Supplier & Exporter of Incoloy 825 Flanges (UNS N08825) has good mechanical properties from moderately to high temperatures. It has good anti-oxidation and non-oxidizing heat acid performance. Incoloy 825 is a nickel-iron-chromium alloy with molybdenum and copper additives that is used in oil and gas well pipes, chemical processing, nuclear fuel reprocessing, acid production, pollution control equipment, and pickling. Incoloy 825 Weld Neck Flanges, Incoloy 825 Bridas is used for equipment for recovery of spent nuclear fuel, propeller shafts, tank trucks, and so on. Incoloy 825 Socket Weld Flanges, Incoloy 825 Bridas is the forerunner of many of the Molybdenum containing nickel iron chromium alloys which have seen service over the past century.
Incoloy 825 Flanges is also used in Marine exhaust systems, Sulphuric acid piping and vessels. Incoloy 825 Pipe Flanges, Incoloy 825 Bridas is as well used in chemical processing, acid production, nuclear fuel reprocessing, oil and gas well piping, propeller shafts, and so on. We are mainly Export in Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates, UAE etc.
