Stainless Steel Wel-Neck Flanges

The addition of chromium enhances resistance and boosts immunity to corrosion in stainless steel weld neck flanges. While long-welded SS flanges may come at a relatively higher cost compared to other flange types, their exceptional durability justifies the investment. The long tapered hub of WN SS flanges facilitates the welding of pipes, providing a secure connection.

Stainless steel welding neck flanges are a preferred choice in industries such as chemicals, petroleum, and pharmaceuticals, thanks to their superior resistance to oxidation and reduction. Trimac Piping Solutions is dedicated to offering these high-quality stainless steel welded flanges to its customers at the most competitive prices available, ensuring both cost-effectiveness and top-notch performance.
