Key Properties
1. Tensile & Bend Strength
- Tensile Strength: 515–1050 MPa (Grade 304/316L), optimized for high-stress applications like oil & gas pipelines. Cold-worked variants achieve up to 1200 MPa for extreme conditions.
- Bend Strength: Austenitic microstructure ensures resistance to deformation even at 90° angles. Stainless steel pex elbow variants maintain flexibility with a bending radius of 1D–10D for tight spaces.
2. Identification & Traceability
- Laser Etching: Permanent markings include material grade (e.g., SS316L), size, and certification codes (ASME B16.9).
- Color Coding: Optional epoxy-coated ends (silver/black) for quick identification in multi-pipeline systems.
3. Weight Calculation
For stainless steel pipe elbows, use the formula:
- W: Weight (kg)
- S: Wall Thickness (mm)
- D: Outer Diameter (mm)
- R: Bend Radius (1D or 1.5D).
Example:
For a 4″ SCH40 elbow (D=114.3mm, S=6.02mm, R=1.5D):
4. Why Stainless Steel Rusts?
Despite inherent corrosion resistance, environmental factors can cause localized rust:
- Passive Layer Damage: Scratches or abrasive cleaning disrupt the chromium oxide layer, exposing iron to oxidation.
- Galvanic Corrosion: Contact with carbon steel in humid environments creates electrochemical reactions.
- Chloride Exposure: Coastal or chemical settings accelerate pitting in grades like 304/316L.
- Organic Contaminants: Residual food acids or oils degrade surfaces if not sanitized promptly.
- High-Temperature Scaling: Prolonged exposure >400°C oxidizes chromium, reducing protective properties.
Why Choose Our Stainless Steel Elbows?
- Global Compliance: Meets ASME, DIN, JIS, and 3A standards for cross-industry compatibility.
- Custom Sizing: Tailored stainless steel pipe elbow dimensions and wall thickness (SCH5S–XXS) for unique projects.
- Hygienic Design: Mirror-polished surfaces (Ra ≤0.8μm) prevent bacterial growth in food/pharma industries.
- Lifetime Warranty: Hydrostatic, radiographic, and ultrasonic testing ensure zero defects.
- Sustainable Production: Recycled SS304/316L reduces environmental impact without compromising durability.
