Duplex blind flange and slip on flanges suppliers in UAE
What are duplex flanges?
The duplex material belongs to the family of stainless steel. It comes with a combination of two phases, ferrite and austenite in equal amounts. The Duplex Stainless Steel Flanges come with increased strength and high toughness. The Duplex Flange Material is also known for its high weldability, and resistance to different types of corrosions. The Duplex Flange Material has a low nickel content and thus, they are cheaper compared to the austenitic stainless steel.
The Duplex Steel Slip On Flanges show higher yield strength, compared to the typical; martensitic, austenitic, and ferritic grades. However, the working temperature of ASTM A182 Duplex Steel Threaded Flanges is quite narrow as they are prone to precipitation due to intermetallic phase, which starts occurring above 300 degrees C. The properties help the ASME SA182 Duplex Steel Socket weld Flanges to be used in industries like paper production, desalination, oil and gas, construction, etc.
