Stainless Steel Heat Exchanger Tubes – U Bend
Our Product
Heat Exchanger Tubes – U Bend
Anand Seamless Ltd. specializes in manufacturing U Bend Heat Exchanger Tubes made from high-grade Stainless Steel. These tubes are designed for compact heat exchanger designs where space optimization and efficient thermal transfer are key. The U-bend configuration is ideal for high-pressure and high-temperature applications where straight tubes are impractical.
Our in-house U-bending facility is fully equipped to produce tubes with tight radius bends and minimal wall thinning. Stress relieving is carried out on all bends in compliance with TEMA (Tubular Exchanger Manufacturers Association) standards, ensuring long-term performance and reliability.

Frequently Asked Questions (FAQs)
What bending radii are possible for U Bend tubes?
We offer bend radii from a minimum of 1.5 times the tube diameter up to 1000 mm.
Do the U-bends undergo stress relieving?
Yes, all U-bends are stress-relieved in accordance with TEMA standards.
Can I order tubes with specific leg lengths?
Absolutely. We can customize leg lengths and bend radii as per your design specifications.
Is there any thinning allowed in the bend area?
We ensure minimal thinning, typically less than 10%, well within acceptable design limits.
