Product Introduction

Stainless steel reducer for smooth pipe-size transitions, with 304/316 corrosion resistance, weld-ready ends, and accurate dimensions for chemical, food, seawater, and industrial pipelines.

 

Key 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.
