Detailed Introduction

Product Overview

DTC stainless‑steel pipe reducer is a butt‑weld pipe fitting designed to connect pipes of different diameters and transition flow from a larger to a smaller pipe size (or vice versa). Manufactured from premium 304 or 316L stainless steel with precision forming, our reducers are available in both concentric and eccentric types to suit different piping layout requirements — making them essential for water supply, oil & gas, chemical processing and industrial piping systems requiring flow rate adjustment or pipe size transition.

Core Product Advantages

  • Premium Stainless Steel: 304/304L and 316/316L grades for excellent corrosion resistance and durability
  • Two Types Available: Concentric reducer for centered flow, eccentric reducer for offset pipe alignment
  • Smooth Flow Transition: Tapered design minimizes turbulence and pressure loss during diameter change
  • Butt‑Weld Connection: Full penetration weld creates strong, permanent, leak‑proof pipe joints
  • Precision Dimensions: Tight tolerances ensure perfect pipe alignment and fit on both ends
  • Wide Size Range: Various diameter ratios to meet different flow rate requirements

Available Types

  • Concentric Reducer — both ends share the same centerline, for centered flow transition
  • Eccentric Reducer — offset centerline, for flat‑bottom pipe alignment and to prevent air pocket formation
