Introduction
ASTM A815 WPS32205 Seamless 180° Bend is a duplex stainless steel pipe fitting designed for applications requiring a full 180° flow redirection while maintaining strength and corrosion resistance. Manufactured from UNS S32205 duplex stainless steel, this seamless bend provides excellent performance in chloride-rich environments such as seawater and chemical processing.
DLSS supplies DN50, SCH10S, centerline dimension (CD) = 143 mm bends, produced to ASTM A815 and compliant with ASME B16.9, ensuring dimensional accuracy and long service life.
