Description

Technical Field

[0002] Titanium alloy tubes are tubes made of titanium alloys. Titanium alloys can be divided into three categories according to their organization, namely, titanium with aluminum and tin elements added, titanium with aluminum, chromium, molybdenum, vanadium and other alloy elements added, and titanium with aluminum and vanadium and other elements added. They have high mechanical properties, excellent stamping properties, and can be welded in various forms. The strength of the welded joint can reach 90% of the strength of the base metal, and the cutting performance is good. Titanium tubes have high corrosion resistance to chlorides, sulfides and ammonia. The corrosion resistance of titanium in seawater is higher than that of aluminum alloys, stainless steel and nickel-based alloys. Titanium also has strong water impact resistance. Titanium alloy tubes are widely used in aerospace, shipbuilding, chemical, medical and other fields.
