Technical Properties
Tensile & Bend Strength
Our stainless steel tubing elbows are engineered for high-pressure industrial systems. The tensile strength of 304-grade elbows exceeds 520 MPa, ensuring structural integrity in corrosive environments like chemical plants or marine exhaust systems. For 1 1/2 stainless steel elbow variants, cold-forming processes optimize bend strength, achieving a smooth 1.5D–3D radius to reduce turbulence and pressure drop. The 316L-grade elbows, with ≥860 MPa tensile strength, are ideal for chloride-rich environments due to their 2-3% molybdenum content.
Weight Calculation
Calculate elbow weight using:
Example: A 1 1/2 stainless steel elbow (SCH40, 48mm diameter, 4mm wall thickness) weighs ~0.4 kg.
Identification Methods
- Laser Etching: ANSI/ASME codes (e.g., "304" or "316L") for traceability.
- QR Codes: Linked to mill test reports (MTRs) with chemical composition and heat treatment data.
Why Stainless Steel Rusts & Prevention
While stainless steel tubing elbows resist rust due to their chromium oxide layer (≥10.5% Cr), specific conditions trigger corrosion:
- Chloride Exposure: Coastal or industrial environments cause pitting in 304 stainless steel 90 degree elbow if passivation is incomplete.
- Mechanical Damage: Scratches on polished surfaces expose the base metal. Use non-abrasive cleaning tools.
- Galvanic Corrosion: Contact with carbon steel or aluminum in mixed-metal systems accelerates degradation. Isolation gaskets are recommended.
- Organic Contaminants: Food residues or pollutants degrade the passive layer. Clean biweekly with pH-neutral solutions.
Prevention Tips:
- Post-installation passivation with nitric acid.
- Avoid chloride-based cleaners.
- Regular visual inspections for surface defects.
Applications
- Industrial Exhausts: stainless steel tubing elbows for automotive, marine, and HVAC systems.
- Chemical Processing: 316L-grade elbows for acid/alkali transport.
- Food & Pharma: 3A-certified 1 1/2 stainless steel elbow with electro-polished interiors for hygiene.
