Sulfuric acid reactor lining (2.0 mm × 1000 mm coil)
Stainless steel coils used for sulfuric acid reactor linings commonly installed in chemical production workshops, providing reliable corrosion resistance and structural stability in aggressive chemical processing environments.
Concentrated seawater heat exchangers (1.5 mm × 1219 mm coil)
Stainless steel coils applied in concentrated seawater heat exchangers operating in seawater desalination plants, offering strong resistance to chloride corrosion and dependable performance in high-salinity conditions.
Use ERNiCrMo-3 welding wire; post-weld solution treatment recommended to ensure optimal microstructure and maintain maximum corrosion resistance for international engineering standards.
Custom lead time 15–20 days, complete corrosion test reports and original Mill Test Certificates (MTC) provided to guarantee smooth customs clearance for projects in Europe, the Middle East, Asia, and Africa.
Walmay will help match the right stainless product form and specification for your application, confirm quantities and packing needs, and provide requested documents based on order requirements.
