In December 2025, JN Company received an inquiry from an Argentine offshore platform procurement officer. Argentina requires a large quantity of WN flanges resistant to seawater and hydrogen sulfide rings for oil and gas development, primarily for transporting oil and natural gas containing corrosive substances.
F53 (UNS S32750 Super Duplex Stainless Steel) is a critical piping component for connecting pipelines carrying highly corrosive media, such as seawater desalination, chemical transportation, and equipment, exhibiting excellent resistance to chloride stress corrosion cracking, pitting corrosion, and crevice corrosion.
Weld neck flange, also known as a welding neck flange, high-hub flange, or tapered hub flange. It consists of a circular disk with a protruding rim around the circumference, featuring a series of drilled holes for bolting to another flange or component. The defining characteristic is its long, tapered hub (or neck), which gradually transitions to match the pipe's wall thickness, allowing for a butt weld connection.
