DTC Carbon Steel Butt‑Weld Pipe Fittings | Elbow Tee Reducer Cap

Product Overview

DTC carbon steel butt‑weld pipe fittings are a complete range of industrial piping components including elbows, tees, reducers and end caps. Manufactured from Q235B or 20# carbon steel with precision forming and machining, our fittings connect via butt‑welding to form strong, leak‑proof pipeline systems. They are widely used in water supply, oil & gas, chemical processing, power generation and various industrial process piping applications.

Core Product Advantages

• Quality Carbon Steel: Q235B/20# carbon steel for good weldability and reliable structural strength
• Butt‑Weld Connection: Full penetration weld creates strong, permanent, leak‑proof pipe joints
• High Pressure Resistance: Suitable for high‑pressure and high‑temperature industrial piping systems
• Complete Product Range: Elbows, tees, reducers, caps and more for full‑project piping solutions
• Precision Dimensions: Tight tolerances ensure perfect pipe alignment and fit
• Standard Compliance: Manufactured to international standards for universal compatibility

Available Fitting Types

• 90° Elbow (Long Radius / Short Radius) — for pipeline direction change
• 45° Elbow — for mild‑angle pipeline turning
• Equal Tee — for pipeline branch connections
• Reducing Tee — for branch diameter reduction
• Concentric Reducer — for pipe diameter transition
• Eccentric Reducer — for offset pipe diameter transition
• End Cap — for pipeline end closure
