Petrochemical Equipment Tube Sheet Product Processing Case：16Mn III + ERCuNi

This case features the fabrication of a tube sheet for petrochemical heat exchange equipment. The base material, 16Mn III, offers excellent strength and weldability, while the inner surface is clad with ERCuNi (Copper-Nickel alloy) to provide superior corrosion resistance against seawater, brine, and chemical media.

16Mn III + ERCuNi Tube Sheet

Using automated welding technology, including GTAW and MIG cladding, a uniform and dense Cu-Ni alloy layer is applied to all fluid-contact areas. This ensures high integrity bonding, low dilution, and long-term protection in aggressive environments typical of refining and chemical processing plants.

Key Features:

• Base material: 16Mn III, high-strength carbon steel with excellent mechanical properties

• Cladding alloy: ERCuNi, ideal for resisting corrosion in chloride-rich and marine environments

• Applications: Shell-and-tube heat exchangers, condensers, and pressure vessels in petrochemical facilities

• Enhanced service life, reduced maintenance, and compliance with industry corrosion standards
