1. Advantages of Freeman Valve's titanium valves:

1.1 Titanium Gr. 2 (UNS R50400) valves are made of industrial pure titanium and can be used in conventional seawater, nitric acid, and media without significant crevice corrosion.

1.2 Titanium Gr. 3 (UNS R50550) valves are also made of industrial pure titanium with increased strength and can be used in higher-pressure seawater, nitric acid, and media without significant crevice corrosion.

1.3 Titanium Gr. 10 (UNS R58030) valves are made of Ti-Ni-Mo corrosion-resistant alloy, with significantly higher resistance to crevice corrosion than Titanium Gr. 2 (UNS R50400) and Titanium Gr. 3 (UNS R50550) valves. They can be used in geothermal well heat exchange pipelines, geothermal fluid transportation pipelines (typical scenario of high-temperature chlorinated brine), in situations with sealed gaps, and in high-temperature chloride +... 1. Equipment operating in weak acid environments (heat exchangers, tower internals), oil and gas, nearshore: sulfur-containing, low-temperature acidifying seawater equipment, hydrometallurgy, high-temperature brine systems in salt chemical industries.

2. Precautions for using titanium valves:

2.1 Titanium Gr. 2 (UNS R50400) valves have insufficient corrosion resistance in weak reducing acids (dilute hydrochloric acid, dilute sulfuric acid) and high-temperature confined crevices, and are prone to crevice corrosion;

2.2 Titanium Gr. 2 (UNS R50400) valves cannot be heat-treated for strengthening; high-temperature strength decay is significant, and the long-term operating temperature generally does not exceed 315℃;

2.3 Titanium Gr. 3 (UNS R50550) valves have poor resistance to reducing acids and high-temperature crevice corrosion;

2.4 Titanium Gr. 10 (UNS R58030) valves are less effective than palladium alloy Titanium Gr. 7 valves in resisting strong reducing concentrated acids (concentrated hydrochloric acid, concentrated sulfuric acid); they are not suitable for extreme strong reducing conditions.
