1″ Class 150 Raised Face SS304 Weld Neck Flange

Engineered for high‑strength pipe connections, this 1‑inch weld‑neck flange features a tapered hub that evenly distributes stress, making it ideal for high‑pressure and high‑temperature industrial applications. The precision‑machined raised‑face (RF) sealing surface, rated ANSI Class 150, ensures a reliable, leak‑resistant joint when paired with compatible gaskets.

Constructed from premium 304 stainless steel, the flange offers exceptional resistance to corrosion, rust, moisture, and chemicals, suitable for indoor, outdoor, marine, and harsh process environments. Its butt‑weld design provides a smooth bore transition that minimizes turbulence, reduces stress concentration, and improves flow efficiency—perfect for permanent installations in water, oil, gas, steam, chemical processing, HVAC, power generation, and other demanding industrial systems.
