Product Details

The 304 Stainless Steel Flange with Neck Butt Welding Method is manufactured using high quality stainless steel materials selected for durability, corrosion resistance and long term performance. Grade 304 stainless steel is widely used in industrial applications because of its excellent mechanical properties and resistance to oxidation in various environments.

Recommended Image: Stainless steel plates, rings or forged materials before flange production.

The manufacturing process includes raw material preparation, forging or machining, drilling, neck forming, surface finishing and quality inspection. Advanced production equipment ensures precise flange dimensions, accurate bolt hole positioning and consistent welding end specifications.

The weld neck design provides better load distribution compared with standard flange structures. The long tapered neck creates a gradual connection between the pipe and flange, reducing stress concentration during operation. This makes it especially suitable for systems exposed to pressure changes, vibration or high temperature conditions.
