Titanium Check Valve

Titanium Check Valve – Corrosion-Resistant Exotic Alloy Construction

Titanium check valves deliver unmatched corrosion resistance for African seawater service (desalination plants, offshore platforms, coastal facilities), chlorinated water systems, and aggressive chemical applications where stainless steel suffers pitting, crevice corrosion, or stress corrosion cracking. Titanium’s passive oxide film provides immunity to chloride-induced corrosion mechanisms that destroy conventional stainless steel in months—enabling 30-50 year service life in North African desalination plants, South African coastal mining facilities, and offshore applications throughout West African waters.

Key African applications: (1) Seawater cooling systems for power plants and refineries along African coastlines, (2) Desalination plants in Egypt, Morocco, Algeria, Libya with high-salinity Mediterranean/Red Sea feedwater, (3) Offshore platforms in Nigerian, Angolan, Ghanaian waters with continuous saltwater exposure, (4) Chemical processing of brines, chlorinated compounds, and oxidizing acids at North African fertilizer and chlor-alkali plants, (5) Mining operations in coastal regions (Namibia, South Africa) where salt spray causes rapid stainless steel degradation.

Titanium vs. Stainless Steel Material Selection

Specify Titanium When: (1) Seawater or high-chloride service (above 200 ppm Cl⁻), (2) Oxidizing acids (nitric, chromic), (3) Chlorinated hydrocarbons and bleaches, (4) Temperature below 300°C (titanium oxidation limit), (5) Lifecycle cost analysis justifies 5-10× initial cost through extended service life eliminating frequent replacements.

Specify Stainless Steel When: (1) Freshwater or low-chloride service, (2) High temperature above 300°C (stainless maintains strength, titanium oxidizes), (3) Reducing acids (hydrochloric, sulfuric without oxidizers)—titanium susceptible, (4) First cost critical and service life 5-10 years acceptable.
