Weld Neck Flange Carbon Steel & Stainless Steel | ANSI & DIN Standards | PN6 to 1500 LBS | Sizes 1/2” to 48”

Weld Neck Flanges are engineered from durable Carbon Steel (A105, ASTM A234) and Stainless Steel (SS 400, SS 304/L, SS 316/L), suitable for critical applications requiring strong, leak-proof connections. These flanges comply with ANSI/ASME B16.5 and DIN standards and support pressure classes from PN6 up to 1500 LBS. Their beveled ends allow for secure butt welding to pipelines. The surface finish options include black anti-corrosion coating or mill finish, making them adaptable for various industrial environments including oil & gas, petrochemical, and chemical plants. Sizes range from 1/2” (15 NB) to 48” (1200 NB).
