Mechanical Properties
Tensile Strength
The stainless steel elbows exhibit exceptional tensile strength (≥515 MPa for Grade 304; ≥620 MPa for Grade 316), ensuring resistance to deformation under high-pressure conditions. This property is critical for industrial applications such as oil and gas pipelines, where mechanical stress is frequent.
Bend Strength
Designed to withstand cyclic loading, these elbows maintain structural integrity even under repeated stress. The bend strength (≥205 MPa for 304) is enhanced by seamless manufacturing techniques, reducing weak points.
Identification & Marking
Each elbow is laser-etched or stamped with the following:
- Material Grade (e.g., 304, 316L)
- Size (NPS and DN)
- Wall Thickness (SCH)
- Standard Compliance (ANSI B16.9)
- Manufacturer’s Logo
This traceability ensures compliance with global quality standards.
Weight Calculation Formula
Weight (kg) = / 1000
Example: For a 6" SCH40 elbow (OD = 168.3mm, WT = 7.11mm):
Weight ≈ 2.45 kg. Custom weights for stainless steel flanged elbows are calculated based on flange dimensions.
Why Stainless Steel Elbows Resist Rust?
While stainless steel is inherently corrosion-resistant, improper handling or environmental factors can cause localized rusting:
- Chrome Depletion: Insufficient chromium content (<10.5%) weakens the passive oxide layer.
- Chloride Exposure: Coastal or chemical environments accelerate pitting corrosion in 304 grades; 316/L is preferred for such conditions.
- Mechanical Damage: Scratches or weld spatter disrupt the surface, exposing raw steel to oxidation.
- Intergranular Corrosion: Poor welding practices (e.g., lack of argon shielding) cause carbide precipitation in heat-affected zones.
Key Advantages
- Durability: Withstands extreme temperatures and pressures, ideal for nuclear plants and petrochemical systems.
- Hygienic Design: Electro-polished surfaces prevent bacterial growth, compliant with FDA and 3A sanitary standards.
- Customization: Available in stainless steel flanged elbow, threaded, or grooved designs to match system requirements.
