All You Need To Know About Titanium Valves

Titanium alloy valve is a broad term, refers to the valve that the body and inside parts are made of titanium alloy or valves that the body material is carbon steel or stainless steel, and internal parts are made of titanium alloy valve. As we knew, titanium is a reactive structural metal that easily reacts with oxygen to form on the surface a thick, stable oxide film that can react with oxygen to regenerate the oxide film even if it is harmed. It can withstand the deterioration of a variety of corrosive sources, and offers a better solution to corrosion and strength than that of stainless steel , copper or aluminium valves.

Features

• Strong corrosion resistance, mechanical strength and lightweight.
• In the atmosphere, in freshwater, seawater, and high-temperature water vapour, it is almost noncorrosive.
• It has strong resistance to corrosion in royal water, chlorine water, hypocaloric acid, humid chlorine gas and other media.
• It's also very corrosion resistant in alkaline media.
• It is highly resistant to chlorine ions (CIs), and has excellent chloride ion corrosion resistance.
• Corrosion tolerance for Titanium Valvesin organic acids depends on the degree to which the acid is diluted or oxidised.
• Resistance to corrosion in reducing acids is based on the presence of a corrosion inhibitor in the medium.

Aerospace

Due to its high strength ratio, corrosion resistance, titanium and titanium alloy valves can be commonly used in the aerospace industry. The Inconel 600 Tube, stop valve, search valve, needle valve, plug valve, ball valve, butterfly valve, etc. Pure titanium and titanium alloy is commonly used in aircraft pipelines.

Chemical industry

Often in chlorine-alkali, salt, synthetic ammonia, ethylene, nitric acid , acetic acid and another strong corrosion setting, titanium alloy valves that have better corrosion resistance can replace common metals such as stainless steel, copper , aluminium, especially in pipeline control and regulation.

Warships

Russia is one of the world's first states to use titanium alloy for warships. Russia developed a series of attack submarines from the 1960s to the 1980s, of which a large number of titanium alloy pipes and valves were used in its seawater scheme.

Power plant

Most nuclear power plants are installed on the coast, and titanium valves are used in nuclear power projects because of their excellent resistance to seawater corrosion. Forms include a safety valve, globe valve, diaphragm valve, ball valve, etc.

In addition, titanium valves and Inconel 600 Pipe are also used in the paper industry, food and pharmaceutical processing, and other fields as a special media and environment fluid control equipment.

Conclusion

Overlay welding alloys widely used include alloys based on cobalt, alloys based on nickel, alloys based on iron, and alloys based on copper. Due to its good high-temperature performance, excellent thermal strength, wear resistance , corrosion resistance and heat-resistance fatigue performance, cobalt-based alloy is more used in valves than iron or nickel-based alloy. These alloys can be made into the electrode, wire (including flux-cored wire), flux (transition alloy flux) and alloy powder, etc., using methods such as submerged arc automatic welding, manual arc welding, tungsten argon arc welding, plasma arc welding, oxygen-acetylene flame welding in all forms of valve shell and surf sealing.
