Product Features

• One-piece pressed forming creates a smooth concentric transition surface with gentle flow and low resistance.
• 304/316 stainless steel resists acids, alkalis, salt spray, and corrosive pipeline media.
• Standard welded ends and uniform wall thickness support leak-resistant performance under high-pressure conditions.
• Accurate dimensions suit seamless and welded stainless steel pipes for reliable size transition.
