Premium Stainless Steel 90 Degree Elbow | Seamless Flow Control

Premium Stainless Steel 90 Degree Elbow | Seamless Flow Control

​Technical Specifications

​Performance Attributes

​Tensile Strength

The ​stainless steel 90 degree elbow achieves a tensile strength of ​**≥520 MPa**, ensuring structural integrity under high-pressure conditions such as industrial exhaust systems or chemical pipelines. This strength is derived from the alloy’s chromium (16–18%) and molybdenum (2–3%) content, which enhances resistance to stress corrosion cracking.

​Bending Strength

With a yield strength of ​**≥205 MPa**, the elbow maintains its shape even under extreme mechanical stress. Precision cold-forming and seamless welding techniques eliminate weak joints, making it ideal for applications like HVAC systems or marine pipelines.

​Identification & Marking

Each ​stainless steel pipe elbow is laser-etched with a unique identifier (e.g., "316L-5IN-ASTM"), ensuring traceability and compliance with international standards. This includes batch numbers, material grade, and certification codes for quality assurance.

​Weight Calculation

The weight of a ​5 inch 90 degree exhaust elbow stainless steel is calculated using:
$\text{Weight (lbs)}=0.02466\times (OD-WT)\times WT\times L$
Where:

• $OD$ = Outer Diameter (5 inches)
• $WT$ = Wall Thickness (e.g., 0.154" for SCH40)
• $L$ = Length of the elbow (standard 1.5D radius).

For example, a 5" SCH40 elbow weighs approximately ​3.2 lbs.

​Why Stainless Steel Can Rust

While ​stainless steel 90 degree elbows resist corrosion, rust may occur under specific conditions:

1. ​Chloride Exposure: Prolonged contact with saltwater or chlorine-based chemicals degrades the passive chromium oxide layer.
2. ​Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in humid environments accelerates oxidation.
3. ​Mechanical Damage: Scratches or improper handling expose the base metal to oxygen and moisture.

​Craftsmanship & Design

• ​Seamless Construction: Forged from ​stainless steel pipe elbow blanks using mandrel pressing, ensuring uniform wall thickness and smooth internal surfaces.
• ​Precision Welding: TIG-welded joints with argon gas shielding eliminate porosity, enhancing durability in high-vibration environments.
• ​Surface Treatments: Electropolishing reduces micro-surface roughness, minimizing friction and bacterial growth in sanitary applications.

​Applications

• ​Exhaust Systems: ​5 inch 90 degree exhaust elbow stainless steel is widely used in automotive and industrial exhausts for its heat resistance.
• ​Chemical Processing: Resistant to acids, alkalis, and solvents, suitable for chemical transfer pipelines.
• ​Marine Engineering: Ideal for saltwater cooling systems due to superior pitting resistance.
