Application

Small Diameter Pipes (NPS 1/8″ to 2″):
Heat exchangers: Titanium’s corrosion resistance and high thermal conductivity make welded pipes suitable for heat exchangers in chemical processing and power generation.
Hydraulic systems: Welded titanium pipes serve in low-pressure to moderate-pressure hydraulic systems where weight savings and corrosion resistance are essential.
Food and beverage processing: Titanium’s biocompatibility and corrosion resistance make welded pipes suitable for food and beverage applications, especially where hygiene is critical.
Medium Diameter Pipes (NPS 2 ½” to 8″):
Chemical processing: Like small-diameter pipes, it is suitable for transporting corrosive chemicals in various processes.
Marine applications: Seawater systems and shipbuilding, balancing cost and corrosion resistance.
Desalination plants: Serve to transport brine or product water in less critical sections of desalination plants.
Large Diameter Pipes (NPS 10″ and above):
Water treatment: Serve for large water distribution systems and wastewater treatment facilities, offering long-term durability.
Chemical and industrial processing: Suitable for transporting large volumes of fluids in various industrial applications.
Architectural and structural applications: Large-diameter welded titanium pipes are suitable for architectural designs and structural elements where corrosion resistance and aesthetics are essential.
