Heavy-Gauge Stainless Steel 90 Degree Elbow | Custom Welded

Product Detail Page: Heavy-Gauge Stainless Steel 90 Degree Elbow | Custom Welded

Technical Specifications

Mechanical Properties

Tensile Strength

Engineered for extreme industrial environments, our heavy-gauge stainless steel elbows deliver unparalleled tensile strength:

• Grade 304: ≥520 MPa (annealed) / ≥860 MPa (cold-worked)
• Grade 316L: ≥485 MPa (annealed) / ≥750 MPa (cold-worked)
  This ensures resistance to deformation in high-pressure hydraulic systems, chemical processing plants, and offshore drilling platforms.

Bend Strength

The one shot 90 degree stainless steel elbow design eliminates weld seams, enhancing bend strength (≥225 MPa for Grade 304) and reducing turbulence. Hydrostatic testing at 1.5× rated pressure guarantees leak-proof performance in cyclic stress applications like power generation and LNG transport.

Identification & Marking

Each elbow pipe stainless steel unit is laser-etched with traceable identifiers for compliance and quality assurance:

• Material Grade (e.g., 316L)
• Heat Number (full traceability via mill certificates)
• Pressure Class (e.g., 3500#)
• Certification Marks (UKCA, ISO, NACE)
  This system aligns with global standards like ASME B16.9 and DIN 2605, simplifying audits and replacements.

Weight Calculation Formula

Weight (kg) = $(OD-WT)\times WT\times 0.02466\times Length(mm)$ / 1000
Example: For a 12" SCH80S elbow (OD = 323.9mm, WT = 10.31mm):
Weight ≈ 8.92 kg. Custom stainless steel elbows UK orders include adjustments for thread depth, flanges, or reinforced collars.

Why Stainless Steel Elbows May Corrode?

While stainless steel is corrosion-resistant, specific conditions can trigger localized rust:

1. Chloride-Induced Stress Corrosion (CISCC): Coastal or chemical environments degrade Grade 304. Upgrade to 316L (2.5% Mo) or super duplex steels for chloride-rich settings.
2. Galvanic Corrosion: Direct contact with carbon steel or copper in humid settings accelerates oxidation. Use dielectric gaskets or coatings to isolate metals.
3. Welding Defects: Poor argon shielding during welding causes chromium carbide precipitation. Our elbows undergo post-weld pickling and electropolishing to restore the passive oxide layer.
4. Abrasive Erosion: Particulate-laden fluids erode surfaces. Specify electro-polished interiors (Ra ≤0.4μm) for smooth flow and reduced wear.

Key Advantages

1. Heavy-Gauge Durability: Thick-walled SCH160 and XXS options withstand abrasive slurries and cryogenic temperatures (-250°C).
2. Customization: Available as one shot 90 degree stainless steel elbow (hydraulic-formed) or custom stainless steel elbows UK (threaded, flanged, or grooved).
3. Hygienic Compliance: Mirror-polished (Ra ≤0.4μm) elbows meet 3A, FDA, and EHEDG standards for pharmaceutical and food processing.
