Product Introduction
Stainless Steel Forged Weld Neck Flange is a high-strength pipe connection component designed for demanding piping systems where reliable performance under pressure and mechanical stress is required. Its long tapered hub and butt-weld connection provide a smooth transition between the pipe and flange, helping improve load distribution and connection stability. Forged construction offers excellent structural integrity, dimensional accuracy, and resistance to mechanical stress, while stainless steel provides strong corrosion resistance. Common grades include 304, 304L, 316, and 316L stainless steel for a wide range of industrial environments. Custom sizes, pressure ratings, facing types, dimensions, and precision machining are available according to applicable standards and project requirements.
