High-Quality Stainless Steel 90 Degree Elbow | ANSI Certified

Product Overview

Our 3 stainless steel 45 degree elbow is engineered for precision and durability in industrial and commercial piping systems. Designed to meet ANSI B16.9, ASME, and DIN 2605 standards, this 90-degree elbow ensures seamless flow redirection with minimal turbulence. Ideal for HVAC, chemical processing, and marine applications, it combines corrosion resistance with structural integrity.

Technical Specifications

Key Attributes

1. Tensile & Bend Strength

Our 3 stainless steel 45 degree elbow offers exceptional tensile strength (≥515 MPa for 304, ≥485 MPa for 316L) and bend strength, validated through hydrostatic testing (1.5× working pressure) and ultrasonic inspections. These properties ensure resistance to deformation under extreme thermal cycling and vibrational stress, making it suitable for high-pressure oil and gas pipelines.

2. Identification & Marking

Each elbow is laser-etched with traceable identifiers:

• Material Grade (e.g., 304, 316L)
• Size (OD × Wall Thickness)
• Certification Marks (ANSI, ASME)
• Batch Number (for full supply-chain transparency).

3. Weight Calculation

Weight (kg) = $(OD-WT)\times WT\times 0.02466\times Length$ × 1.5 (90° factor).
Example: A 5" Sch40 elbow (OD: 141.3mm, WT: 6.55mm) weighs approximately 4.2 kg. For long-radius china stainless steel elbow (e.g., 36" CLR), apply a multiplier of 2.0.

4. Corrosion Resistance & Anti-Rust Mechanism

While stainless steel inherently resists rust due to its chromium oxide layer (12-20% Cr), localized corrosion may occur due to:

• Chloride Exposure: Coastal or chemical environments can cause pitting; 316L (2% Mo) is recommended for such cases.
• Mechanical Damage: Scratches or weld splatter disrupt the passive layer, necessitating post-installation passivation.
• Galvanic Corrosion: Avoid contact with dissimilar metals like carbon steel in humid conditions.

Manufacturing Process

1. Material Selection: Premium-grade 304/316L billets sourced from audited mills.
2. Forming: Hot extrusion or mandrel bending for seamless integrity; forged variants for high-pressure systems.
3. Welding: TIG welding with ER308/316L filler rods, followed by post-weld heat treatment (PWHT).
4. Surface Treatment: Electro-polishing (Ra ≤ 0.8 μm) or shot blasting for industrial applications.
5. Quality Assurance: 100% radiographic testing (RT), hydrostatic checks, and spectral analysis.

Applications

• HVAC Systems: Optimized for 45 degree street elbow stainless steel configurations in commercial vents.
• Chemical Processing: Resistant to acidic/alkaline media (pH 2–12).
• Marine Engineering: Mo-enhanced 316L variants for saltwater environments.
• Pharmaceutical & Food: 3A-certified, mirror-finished elbows for hygienic fluid transfer.
