Stainless Steel Elbows – Various Designs and Dimensions

Stainless Steel Elbows – Properties and Dimensions

Pipe elbows are essential components in industrial piping systems. Whether for space-saving installations, flow-optimized systems, or complex plant setups – stainless steel elbows ensure stable, durable, and leak-proof connections.

Materials & Designs – Versatile and Reliable

We offer stainless steel pipe elbows in both seamless and welded designs, tailored to your specific requirements. Our extensive stock includes elbows made from high-quality stainless steels, including:

● 1.4541 – Stable and temperature-resistant, widely used in chemical and process industries
● 1.4462 (Duplex Steel) – Excellent corrosion resistance and mechanical strength
● 1.4410 (Super Duplex Steel) – Highly resistant to aggressive media like chlorides and seawater

Depending on your application, we supply elbows made from austenitic stainless steel, duplex or super duplex grades, as well as heat-resistant special alloys.

Standards & Quality – DIN 2609 and More

WITTE TUBE and WITTE HiTEMP supply stainless steel elbows that comply with all relevant international standards and technical specifications, including:
● DIN 2605-1 / DIN 2605-2, DIN 2609
● EN 10253-4, EN 10253-3
● AD 2000 W2 / W10
● VdTÜV 1252, 418, 421

Advantages of Stainless Steel Pipe Elbows

● High corrosion resistance
● Pressure and temperature resistant
● Long service life
● Hygienic and low-maintenance
● Ideal for aggressive or sensitive media

Whether you need a stainless steel 90 degree elbow for a tight bend or a 45 degree pipe elbow for smooth directional flow – we deliver the right solution for your system.

What Bending Radii Are Available?

We supply elbows in various radii and designs:
● BA2 / SR – Short radius
● BA3 / LR – Long radius
● BA5 – Segment elbows

What Is the Difference Between Long Radius and Short Radius Elbows?

The key difference between long radius and short radius elbows lies in the bend radius – which affects the elbow’s shape, installation space, and flow characteristics.

Criterion	Long Radius Elbow (LR)	Short Radius Elbow (SR)
Bend Radius ®	1.5 × outside diameter (R = 1.5 × D)	1.0 × outside diameter (R = 1.0 × D)
Designation	LR (Long Radius)	SR (Short Radius)
Space Requirement	Higher – requires more space for the bend	Compact – ideal for tight installation areas
Flow Behavior	Optimized – less pressure loss	Higher turbulence and potential pressure loss
Impact on Medium	Gentler on flow, ideal for fast or aggressive media	Increased stress due to sharper redirection
Typical Applications	Chemical, pharmaceutical, plant construction	Compact piping systems, limited installation space
