Duplex alloys are a group of stainless steel that offers much higher mechanical and corrosion resistance properties compared to both 304 and 316 alloys. It also has good resistance to pitting and crevice corrosion because of its chemical composition.

The alloy can be used at higher temperatures, compared to the regularly used grade 304. However, the ASTM A815 UNS S32205 Fittings are not suited to extremely high-temperature environments. They are strictly limited to use up to 300°C. Higher temperatures result in the fittings becoming susceptible to precipitation.
Elbows are fittings that connect a piping system and influence a flow by either 45 or 90 degrees. They are useful in industries such as waste management and oil and gas. An elbow may also be used to connect 2 pipes of different sizes in a customised direction.
Duplex end cap fittings are not just used to terminate a connection in pipelines. But they stop the flow of media while the piping system is inspected, cleaned or maintained.
A return bend is used in systems where sediment accumulation is a common occurrence. When used in a piping system, they prevent the deposition of minerals and sediments in the sprinkler. They also prevent the formation of scales in the pipes. Return bends are typically seen in applications where there is a possibility of future remodelling. They also have good resistance to different chemicals and have good mechanical strength between 300°C to -50°C.
The difference between the fitting’s inner and outer diameter will give you the thickness for both, the ASTM A815 WPS 32205 Long and Short Radius Elbow.
