About Duplex 2205/ UNS 32205/ UNS 31803 Flanges

The Duplex 2205 Flanges are made of dual-nature steel with ferritic microstructures. The material is resistant to corrosion under chloride stress. In corrosive settings, it is employed. One of the low-pressure varieties of the flanges is the Class 150 UNS S31803 Flange. The classes are based on the pressure capacity of the flanges. The Duplex UNS S32205 Orifice Flange, the most popular type of duplex orifice flange, is one of the several flange variations. Depending on the need, different flanges have different applications.

ASTM A182 Duplex S31803 Flanges are employed for high-pressure applications and high-pressure vessels. When working in chloride-rich conditions, the temperature can reach 150 degrees Celsius. This material grade includes welded, bolted, and threaded flanges. Several sorts, such as the Duplex SAF 2205 Flanges, are strengthened by having a socket welded onto them. The material’s minimum yield and tensile strengths are 448 MPa and 621 MPa, respectively. The Duplex Steel S31803/S32205 Flange increases the surface for attachment. It is applied as a pair in two parts.

There are ring-type joint flanges, flat faces, and raised face flanges. For various connections, each distinct kind is required. With more surfaces, the face types facilitate welding and fastening techniques. To seal a pipeline, utilize the DIN 1.4462 Flange. Carbon, manganese, silicon, phosphorus, sulfur, chromium, molybdenum, nickel, and nitrogen make up the typical duplex flange material. With a melting temperature of 1420 degrees Celsius, these Flanges and other flanges are solid. For applications involving high temperatures and high temperatures, the flanges adhere to the ASTM A182 standard.

Features of Duplex 2205/UNS 32205/UNS S31803 Flanges :

With more than 80% of the duplex stainless-steel market, 2205 is the Duplex stainless steel that is most frequently utilized. In various settings where 316L is typically utilized, the 2205 alloy offers improved corrosion resistance with the added benefit of higher yield strength. To make sure that no harmful phases, like sigma, are present in the supplied product, all 2205 alloys are metallic substrate inspected. It is frequently utilized as welded pipe or tubular parts. The alloy has also been employed as a moulded and welded sheet product when protection against erosion and chloride SCC is essential. This uncommon Duplex 2205 Flanges alloy is used in the petrochemical processing and exploration of oil and gas applications. Due to their capacity to endure a high mechanical strain in saltwater, these Flanges are essential to mechanical assembly and infrastructure.

Offshore oil drilling companies, aircraft exhaust manifolds, petrochemicals, power generation, gas processing, pharmaceuticals, specialty chemicals, pharmaceutical machinery, heat exchangers, and seawater equipment are some of the industries that use duplex steel flanges.
