Product Description
Stainless heat exchanger tubes are high-performance seamless or welded tubes designed for shell-and-tube heat exchangers, condensers, evaporators, and boilers. Manufactured from high-quality austenitic stainless steel, they offer excellent corrosion resistance, high-temperature strength, and efficient heat transfer.
Key Advantages:
- Excellent resistance to pitting, crevice corrosion, and SCC
- Maintains mechanical properties at elevated temperatures
- Smooth inner/outer surface for low fluid resistance
- Suitable for bending, expanding, welding, and other secondary processing
- Fully certified to international standards
