Stainless steel pipe 90° elbow fittings are pipe fittings used to change the flow direction of stainless steel pipes, with a bending angle of 90 degrees. They feature two ports (inlet and outlet) with perpendicular center lines.
Elbow Types:
- Long Radius: Bending radius approximately 1.5 times pipe diameter - reduces pressure loss and fluid resistance
- Short Radius: Bending radius approximately equal to pipe diameter
Material Specifications:
- 304 Stainless Steel: 18% Chromium, 8% Nickel - Good corrosion resistance, heat resistance, and processing performance. Suitable for general corrosive environments, indoor water supply/drainage systems, and food processing equipment.
- 316 Stainless Steel: Contains 2-3% Molybdenum for enhanced corrosion resistance, particularly against chloride ions. Ideal for marine environments and chemical production pipelines.
Dimensional Specifications:
- Nominal Diameter (DN): 15 (1/2"), 20 (3/4"), 25 (1"), 32 (1.1/4"), 40 (1.1/2"), 50 (2"), 65 (2.1/2"), 80 (3"), 90 (3.1/2") mm
- Outer Diameter Examples: DN15 ≈ 21.3mm, DN20 ≈ 26.9mm, DN50 ≈ 60.3mm
Tensile Strength: 520-750 MPa - Ensures the elbow withstands fluid pressure and external stress without breaking.
Yield Strength: 205-210 MPa - Indicates stress when material begins plastic deformation, ensuring stable shape under normal working pressure.
Elongation: >40% for 304 stainless steel elbows - Allows plastic deformation without breaking, improving pipeline system safety and reliability.
Strict dimensional tolerance regulations ensure connection accuracy:
- Outer diameter tolerance: ±0.5 - 1.0mm
- Wall thickness tolerance: ±10 - 15%
Tolerances vary based on pipe size and standard requirements.
Special specifications, non-standard custom fittings, or elbows made by special processes (forging, precision casting) may have significant price variations based on requirements and production difficulty. Bulk purchases typically receive price discounts.
