Review of the Titan large diameter pipe Titanium pipe titanium alloy is a new structural materials. Since titanium has a high melting point, small specific weight, high specific strength, good toughness, fatigue resistance, resistance to acid and alkali corrosion, low thermal conductivity and good resistance to high and low temperatures, the characteristics of low voltage conditions, quick cold and quick heat. It is used in chemical heat exchange equipment and is constantly moving in such sectors as oil, power, desalination, construction and casual.
