Tube Bundle – ASME SB111 C71500 Seamless Tube for Desalination Brine Heaters

Tube Bundle – ASME SB111 C71500 Seamless Tube for Desalination Brine Heaters

Overview

Our Tube Bundles are manufactured using ASME SB111 C71500 seamless tubes, a high-strength 70/30 Copper-Nickel alloy (Cu-Ni) known for exceptional performance in marine and seawater environments. These tube bundles are precision-engineered for heat exchanger applications such as brine heaters, evaporators, and condensers in desalination plants, where corrosion resistance and thermal conductivity are critical.
