200mm diameter custom duplex steel pipe flange
Duplex steels have high resistance to various types of corrosion. Duplex Steel S31803 is an extremely corrosion-resistant, work-hardenable alloy. Duplex steel S31803 butt weld flanges have good high temperature properties.
ASTM A182 S31803 / S32205 Duplex Steel Flanges, 2205 Duplex Pipe Flange, ASME SA182M Duplex Steel S32205 Slip on flange
An austenitic-ferritic stainless variant with a higher stress corrosion cracking resistance in comparison to regular austenitic 304 and 316 stainless, but with a lower toughness and impact strength. This category of material includes grades 2205, F51, F53, and F60. F51 Duplex stainless Flange has increased in popularity over the years due to its excellent chemical and mechanical properties versus their basic stainless counterparts, given especially that the cost differences are minimal now as the availability has increased.
F51 flange is an external or internal ridge between two pipes that provides a method of connecting pipes, valves, pumps and other equipment to form an overall piping system. In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure. F51 flanges do this by fastening two pieces of metal or other material together with a circle of bolts on a lip. This “lip” is a flange. S32205 Flanges can also provide easy access for cleaning, inspection or modification and pipes with flanges can be assembled and disassembled easily. 1.4462 Flanges tend to be either welded or screwed into place. A182 Duplex 2205 Pipe flanges are manufactured in a variety of different materials. The material of a flange is usually set by the choice of the pipe meaning that the flange matches the material of the pipe, whether that is Duplex, Super Duplex, Stainless Steel, Nickel Alloy or 6% Moly.
