‌‌Titanium alloy pipe is made of titanium alloy pipe, titanium alloy can be divided into three categories according to the organization. (1) Aluminum and tin are added to titanium. 2 Alloy elements such as aluminum, chromium, molybdenum and vanadium are added to titanium. 3 Elements such as aluminum and vanadium are added to titanium. They have high mechanical properties, excellent stamping performance, and can be welded in various forms, the strength of the welded joint can reach 90% of the strength of the matrix 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-based alloy. Titanium water impact resistance is also strong.
