ASME / ANSI B16.9 ASTM A815 UNS S32750 Super Duplex Stainless Steel Pipe Fittings Reducer
Duplex 2507 (UNS S32750) is also known as Alloy 2507. It has a higher strength and better corrosion resistance compared to standard duplex stainless steels. It contains a combination of austenitic and ferritic stainless steel, which provides its unique properties.
It has a high resistance to pitting and crevice corrosion in chloride-containing environments. UNS S32750 is often used in harsh environments such as offshore oil and gas production, chemical processing, and desalination plants.

Concentric reducer is designed to reduce the pipe size in a symmetrical manner, with the centerline of the pipe remaining aligned. This means that the two ends of the reducer are on the same axis, creating a smooth transition for fluid or gas flow. Concentric reducers are commonly used in vertical piping systems.
Eccentric reducer is designed to reduce the pipe size in an asymmetrical manner, with the centerline of the pipe not aligned. This creates an offset between the two ends of the reducer, which can be useful in situations where there is a need to avoid trapping air or vapor in the piping system. Eccentric reducers are commonly used in horizontal piping systems.
