ASME B16.9 ASTM A815 UNS S32750 Concentric Reducer – Superior Strength & Corrosion Resistance

Haihao Group proudly supplies ASME B16.9 concentric reducers manufactured from ASTM A815 UNS S32750 (Super Duplex Stainless Steel), meeting the stringent requirements of NACE MR0175 for sour service applications.

Product Overview

The ASME B16.9 concentric reducer is a key component in piping systems, designed to connect pipes of different diameters while maintaining a central axis. This ensures smooth fluid flow, reduced turbulence, and enhanced efficiency in high-pressure and corrosive environments.

Material Advantage – ASTM A815 UNS S32750

Super Duplex Stainless Steel (UNS S32750) offers:

Exceptional corrosion resistance – Ideal for aggressive environments like offshore, chemical processing, and marine industries.

High mechanical strength – With nearly double the yield strength of conventional stainless steel, it ensures enhanced durability and longer service life.

Superior pitting and crevice corrosion resistance – Making it a reliable choice for chloride-rich conditions.

NACE MR0175 Compliance

This product meets NACE MR0175 standards, ensuring resistance to sulfide stress cracking (SSC) in sour gas applications. It is suitable for use in oil & gas and petrochemical industries where exposure to H₂S (hydrogen sulfide) and corrosive environments is a concern.
