Key Attributes
1. Tensile & Bend Strength
The stainless steel elbow exhibits exceptional tensile strength (≥515 MPa for 304, ≥485 MPa for 316L) and bend strength, ensuring resistance to deformation under high-pressure conditions. Rigorous testing, including hydrostatic and ultrasonic inspections, guarantees compliance with international mechanical performance standards.
2. Identification & Marking
Each elbow is laser-etched with:
- Material Grade (e.g., 304, 316L)
- Size (OD × Wall Thickness)
- Certification Marks (ASME, DIN)
- Manufacturer’s Logo (traceability ensured).
3. Weight Calculation
Weight (kg) = × 1.5 (for 90° factor).
Example: A 5" Sch40 elbow (OD: 141.3mm, WT: 6.55mm) weighs approximately 4.2 kg.
4. Corrosion Resistance & Anti-Rust Mechanism
Our stainless steel elbow manufacturers prioritize chromium-nickel alloy composition (18% Cr, 8% Ni for 304; 16% Cr, 10% Ni, 2% Mo for 316L), forming a passive oxide layer that prevents oxidation. Despite this, localized rust may occur due to:
- Chloride Exposure: Aggressive environments (e.g., coastal areas) may cause pitting.
- Mechanical Damage: Scratches or weld splatter disrupting the passive layer.
- Improper Cleaning: Residual contaminants accelerating oxidation.
Manufacturing Process
- Material Selection: Premium-grade stainless steel billets sourced from audited mills.
- Forging/Forming: Hot extrusion or mandrel forming for seamless integrity.
- Welding: TIG welding with ER308/316L filler for welded elbows.
- Surface Treatment: Electro-polishing or passivation to enhance corrosion resistance.
- Quality Assurance: 100% radiographic testing (RT) and hydrostatic pressure checks.
