How much do you know about seamless titanium alloy tubes?
Sep 21, 2024
Seamless titanium alloy pipe is a kind of long pipe made of titanium alloy material with a hollow cross-section and no seams around. Initially, it was mainly used to make aircraft engine compressor parts and structural parts for rockets, missiles and high-speed aircraft. Since the mid-1960s, it has been gradually applied to electrodes in the electrolysis industry, condensers in power stations, heaters in petroleum refining and seawater desalination, environmental pollution control devices and other general industrial manufacturing fields.
Gr.2 Gr.2 Gr.3 Gr.4 are industrially pure titanium, they have high mechanical properties, excellent stamping properties, and can be welded in various forms, welded joint strength up to 90% of the strength of metal, and good cutting and processing performance. Titanium tubing is highly resistant to chlorides, sulphides and ammonia. Titanium corrosion resistance in seawater than aluminium alloys, stainless steel, and nickel-based alloys are also high. Titanium water impact resistance is also stronger
A titanium-based alloy composed of other elements. Used in the manufacture of condenser tubes, which can be used in polluted seawater, water with high suspended solids content, and at high flow rates.
Titanium alloy according to the organisation can be divided into three categories.
1 titanium with aluminium and tin elements.
2 titanium with aluminium, chromium, molybdenum, vanadium and other alloying elements.
3 Titanium with the addition of aluminium vanadium and other elements.) Titanium alloy has high strength and density and small, good mechanical properties, toughness and corrosion resistance is very good. In thermal processing, very easy to absorb hydrogen, oxygen, nitrogen, carbon and other impurities. In addition, the wear resistance is poor, and the production process is complicated.
Titanium industrial production was started in 1948. The development needs of the aviation industry, so that the titanium industry with an average annual growth rate of about 8% development. At present, the world's annual output of titanium alloy processing materials has reached more than 40,000 tonnes of titanium alloy, titanium alloys nearly 30 kinds of brands. The most widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (Gr.1, Gr.2 and Gr.3). China began research on titanium and titanium alloys in 1956; industrial production of titanium began in the mid-1960s and the TB2 alloy was developed.
