SS 316L Weld Neck Flanges

The SS 316L Weld Neck Flange (WN) is a high-integrity forging characterized by its long, tapered hub that transitions smoothly to the pipe wall thickness. This design is butt-welded directly to the pipe, creating a joint with minimal stress concentration and virtually no erosion. This makes it the most robust and preferred type of flange for high-pressure, high-temperature, and critical corrosive services. The 316L designation indicates a low carbon austenitic stainless steel, which is specifically chosen for its superior weldability; the low carbon content prevents sensitization and the resulting intergranular corrosion during the welding process. Furthermore, the inclusion of Molybdenum ensures outstanding resistance to pitting and crevice corrosion in harsh, chloride-containing media. Zeron Fasteners manufactures and supplies reliable SS 316L Weld Neck Flanges conforming to standards like ASME B16.5 and ASTM A182 F316L, ensuring maximum pipeline strength and durability.
