English：DTC Stainless Steel 45° Elbow | Butt‑Weld Pipe Bend Fitting

Product Overview

DTC stainless‑steel 45° elbow is a standard butt‑weld pipe fitting designed to change flow direction by 45 degrees in piping systems. Manufactured from premium 304 or 316L stainless steel with precision machining, our 45° elbows provide gentle flow transition with minimal pressure loss — making them ideal for water supply, oil & gas, chemical processing, food‑grade sanitary and industrial piping applications requiring gradual direction changes.

Core Product Advantages

• Premium Stainless Steel: 304/304L and 316/316L grades for excellent corrosion resistance
• Gentle Flow Transition: 45° angle creates smoother flow with less turbulence than 90° bends
• Smooth Inner Bore: Polished inner surface minimizes flow resistance and pressure drop
• Precision Dimensions: Tight tolerances ensure perfect pipe alignment and fit
• Seamless & Welded Options: Both seamless and welded construction available
• Long Radius Design: R=1.5D for optimal flow characteristics and structural strength

Available Types

• 45° Long Radius (LR) Elbow — standard type
• 45° Short Radius (SR) Elbow — for compact installations
• Matching 90° elbows and 180° return bends for full‑project combinations
