Hengyang PipingHigh-Performance Heat Exchanger U Tubes

SHARE
The U Tubes offered by Hengyang Piping are integral components of high-efficiency heat exchangers and feature lengths up to 30 meters, ideal for large-scale applications. These tubes are manufactured using cold rolling or drawing processes, resulting in a seamless or welded finish and an annealed and passivated surface. Utilizing materials such as Stainless Steel (grades 304, 321, 316, etc.), Duplex/Super Duplex (grades S31803/32205), and Nickel Alloys (like Inconel 625 and Incoloy 825), the tubes meet ASME SA688 standards for structural integrity and performance. Ultra-long stainless steel U tubes crafted from Duplex/Super Duplex Stainless Steel provide superior structural integrity and are designed for high-pressure heat exchangers in power plants, various industrial applications, and high-performance condenser equipment. The company is known for its production capabilities, high-quality control, and capability of customizing solutions to meet specific customer needs in challenging applications.
