]]> Product Overview

DTC carbon 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 Q235B or 20# carbon steel with precision forming, our reducers are available in both concentric and eccentric types to suit different piping layout and pressure requirements — making them essential for water supply, oil & gas, chemical processing, power generation and industrial piping systems requiring flow rate adjustment or pipe size transition.

Core Product Advantages

  • Quality Carbon Steel: Q235B/20# carbon steel for good weldability and reliable structural strength
  • High Pressure Resistance: Suitable for high‑pressure and high‑temperature industrial piping systems
  • 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
  • Wide Size Range: Various diameter ratios and wall thicknesses for different pressure ratings

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

Technical Specifications

  • Material: Carbon Steel Q235B, 20#, Q355B
  • Type: Concentric Reducer, Eccentric Reducer
  • Construction: Seamless, Welded
  • Size Range: 1/2″×1/4″ to 24″×20″ (DN15×DN8 to DN600×DN500)
  • Schedule: SCH 20, SCH 40, SCH 80, SCH 160
  • Pressure Rating: Class 150 to Class 2500, PN10 to PN100
  • End Connections: Butt Weld
  • Surface Finish: Black (as‑rolled), Anti‑rust oil, Painted, Galvanized
  • Temperature Range: -20°C to +450°C (depending on material grade)
  • Standards: ASME B16.9, GB/T 12459, EN 10253, JIS B2311

Application Scenarios

  • Water treatment and distribution systems
  • Oil and gas pipelines
  • Chemical and petrochemical plants
  • Power generation facilities
  • Industrial process piping
  • HVAC and heating systems
  • Fire protection systems
  • Refinery and processing plants
  • Municipal engineering pipe networks

Quality Assurance

DTC carbon steel pipe reducers are manufactured under strict ISO 9001 quality management systems and certified to international standards. Every fitting undergoes comprehensive quality control — including material verification, dimensional inspection, wall‑thickness measurement, hydrostatic testing and non‑destructive testing (NDT) options — to ensure full compliance with customer specifications and industry standards. We provide complete material test reports (MTR) with each shipment for full traceability.
