钛及钛合金具有高比强度、耐高温、耐腐蚀、高韧性、低密度、较宽的工作温度范围和抗疲劳性好的优点,尤其具有优异的抗腐蚀性能,能在大多数酸、碱、盐及海水及海洋环境中使用不腐蚀。钛及钛合金管材由于加工工艺复杂,具有优异的纵向机械性能。因此,钛及钛合金管材在军事工业、核工业、航空航天、海洋产业、石油精炼、化工等领域具有广泛应用。本文对TC4钛合金石油管材的生产和焊接工艺进行了综述,并对钛及钛合金管材在海洋石油开采精炼方面的应用现状和发展前景进行了展望。
Titanium and titanium alloys have the advantages of high specific strength, high temperature resistance, corrosion resistance, high toughness, low density, wide operating temperature range and good fatigue resistance, especially excellent corrosion resistance, , Salt and sea water and marine environment is not corrosive. Titanium and titanium alloy pipe due to complex processing technology, with excellent longitudinal mechanical properties. Therefore, titanium and titanium alloy pipe in the military industry, nuclear industry, aerospace, marine industry, petroleum refining, chemical and other fields have a wide range of applications. In this paper, the production and welding process of TC4 titanium alloy tubing are reviewed. The application status and development prospects of titanium and titanium alloy tubing in the offshore oil refining are also discussed.
