Application of titanium alloy seamless pipe

Titanium alloy seamless pipe is a long strip pipe with hollow section and no joint around it, which is made of titanium alloy material. At first, it was mainly used to make aircraft engine compressor parts and structural parts of rockets, missiles and high-speed aircraft. Since the mid-1960s, it has been gradually applied to general industrial manufacturing fields such as electrodes in electrolytic industry, condensers in power stations, heaters for oil refining and seawater desalination, and environmental pollution control devices.

TA1, TA2 and TA3 are industrial pure titanium. They have high mechanical properties, excellent stamping properties, and can be welded in various forms. The strength of welded joints can reach 90% of the strength of base metal, and the cutting performance is good. Titanium pipe has high corrosion resistance to chloride, sulfide and ammonia. The corrosion resistance of titanium in seawater is higher than that of aluminum alloy, stainless steel and nickel base alloy. Titanium also has strong water impact resistance

An alloy composed of titanium based and other elements. It can be used in polluted seawater, water with high suspended solids content and high flow rate

Titanium alloys can be divided into three types according to their structure

Aluminum and tin are added to titanium

Alloy elements such as aluminum, chromium, molybdenum and vanadium are added to titanium

3 add elements such as aluminum and vanadium to titanium.) Titanium alloy has high strength, low density, good mechanical properties, good toughness and corrosion resistance In addition, the process performance of titanium alloy is poor and machining is difficult In thermal processing, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen and carbon There is also poor wear resistance and complex production process

Titanium alloy is mainly used to make compressor parts of aircraft engine, followed by structural parts of rocket, missile and high-speed aircraft. In the mid-1960s, titanium and its alloys have been applied in general industry, such as electrodes in electrolytic industry, condensers in power stations, heaters for oil refining and seawater desalination, and environmental pollution control devices. Titanium and its alloys have become a kind of corrosion resistant structural materials. In addition, it is also used to produce hydrogen storage materials and shape memory alloys.
