Stainless Steel (SS) Threaded Flange | ½” to 12” | Raised Face | Class 150/300 & PN16
Description:
Stainless Steel Threaded Flanges provide a reliable, welding-free connection option for piping systems in a variety of industrial applications. Manufactured from high-grade stainless steel, these flanges are designed with internal threads (NPT or BSP, depending on regional standards) that screw directly onto matching threaded pipe ends, allowing for quick and secure assembly and disassembly.
Available in nominal sizes from ½ inch to 12 inches, these flanges feature a Raised Face (RF) design to ensure enhanced gasket sealing and reduce leakage risk. The flanges support multiple pressure classes, including ANSI Class 150 and 300, and DIN PN16, making them suitable for low to moderate pressure applications in chemical, water, petrochemical, and HVAC systems.
Manufactured to conform with international standards such as ANSI B16.5 and DIN EN 1092-1, these threaded flanges ensure dimensional accuracy, interchangeability, and optimal mechanical performance. Their corrosion-resistant stainless steel construction enhances durability and longevity, especially in corrosive or hygienic environments.
Threaded flanges are especially useful in applications where welding is impractical or where frequent disassembly is required for maintenance or inspection.
