Superior Stainless Steel 90 Degree Elbow | 5" Heavy-Duty Exhaust Fit

Premium Corrosion-Resistant Solution for Industrial & Marine Systems

Product Specifications

Technical Properties

Tensile Strength

The seamless stainless steel elbow achieves tensile strengths between 515 MPa and 860 MPa, depending on the alloy grade (e.g., 316L for marine environments). This ensures structural integrity under extreme pressure, making it ideal for stainless steel 3 way elbow configurations in complex piping systems. Advanced heat treatments, including solution annealing and quenching, refine the microstructure to prevent stress corrosion cracking.

Bending Strength

Engineered with a smooth internal radius, the elbow minimizes turbulence and maintains bending strength exceeding 350 MPa. This is critical for applications like exhaust systems, where cyclic loading and vibration resistance are paramount. The socket weld elbows stainless steel design ensures leak-proof joints under high-pressure conditions.

Weight Calculation Formula

Calculate approximate weight using:
Weight (kg) = (OD - WT) × WT × 0.02466 × Length (mm)
(OD = Outer Diameter, WT = Wall Thickness).
For example, a 5" SCH40 elbow (OD 141.3mm, WT 6.55mm) weighs 2.8 kg/m.

Identification & Marking

Each elbow is laser-etched with:

• Material Grade (e.g., 316L)
• Size & Thickness (e.g., 5" SCH40)
• Certification Stamp (ASME B16.9, DIN 2605)
• Batch Number for full traceability.

Why Stainless Steel Elbows Resist Rust?

While stainless steel is inherently corrosion-resistant, localized rust can occur under specific conditions:

1. Chloride Exposure: Prolonged contact with seawater or de-icing salts may breach the chromium oxide layer. Grade 316L’s molybdenum content (2-3%) enhances chloride resistance, making it ideal for stainless steel 3 way elbow systems in marine environments.
2. Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in conductive environments creates electrochemical reactions. Insulating gaskets or coatings mitigate this risk.
3. Surface Contamination: Iron particles from tools or grinding can initiate oxidation. Electro-polishing or passivation post-fabrication restores the passive layer.
4. Low Oxygen Environments: Stagnant water or crevices hinder oxide layer regeneration. Regular CIP (Clean-in-Place) cycles in sanitary systems maintain optimal conditions.

Applications

• Marine Exhaust Systems: Withstands saltwater corrosion and high-temperature gases (up to 800°C).
• Industrial Piping: High-pressure chemical processing, HVAC, and oil refineries.
• Sanitary Fluid Transfer: Mirror-polished seamless stainless steel elbow for hygienic food/beverage pipelines.
• Multi-Port Configurations: Stainless steel 3 way elbow designs for complex flow redirection.
