The Welding Neck Flange is a precision-manufactured component essential for piping systems requiring high strength and reliability. Crafted from forged F51 duplex stainless steel with carbon steel base material (grade 1.0038), this flange combines structural integrity with superior corrosion resistance through stainless steel overlay technology.
Designed to EN ISO 9692-2 specifications, this WN flange features a long tapered hub for optimal stress distribution and smooth bore transition. The stainless steel overlay on carbon steel construction provides excellent protection against corrosion, erosion, pitting, and crevice corrosion in demanding industrial environments.
