The secondary task of Duplex Steel Flanges is to provide ease to the worker accessing these systems to either clean, inspect or modifying them. Typically, the applications of Duplex Stainless Steel Flanges are seen in the following industries i.e. Chemical Plant, Chemical Tanker, Thermal power plant, Seawater desalination Plant, Seawater pump, flue gas desulfurization plants, architectural work as well as Pulp and paper plants. These industries make use of a piping system for the transference of media, which very frequently causes some kind of stress on regular flanges.

What Is Duplex Steel Flanges?


On the other hand, using UNS S31803 Duplex Steel Pipe Flanges ensures high performance, improved corrosion resistance and resultant longer service life. Due to the dual nature of the austenite and ferrite microstructure present in an equal proportion, the Duplex Steel RTJ Flange Material inherits properties from both steel classes. Which means, it gains superior ductility and corrosion resistance properties from the austenitic in the alloy and the Werkstoff No 1.4462 BLRF Flange has higher strength and hardness, both properties, which are a part of their ferrite presence. The high temperature strength of Duplex Steel Slip On Flanges is similar to alloy grade 430 in the temperature range between 950 to 1150℃. However, these flanges demonstrate a rapid increase in their tensile strength below 900℃.
