In recent years, due to the shortage of energy, many countries and regions are committed to the comprehensive utilization of geothermal development. Considering the factors such as performance, maintenance, cost and safety, titanium is an ideal material for geothermal development.

   With the development of low cost new alloys and the development of processing technology, the application of titanium in geothermal industry is bound to increasing. The geothermal industry has a high temperature and a large number of oxidizing chlorides, which can cause local erosion of stainless steel or nickel based alloys. The use of titanium materials can solve such problems well.

  The equipment and key components, including valves, gauges, pipes, turbine components, dilatation tubes, steam water separation devices, condensers, impeller, shaft and so on, are selected from foreign equipment and key components are directly exposed to salty geothermal water. More than 450 tons of Gr. 29 titanium alloy hot-rolled seamless tubes have been used in brine production and reinjection in Salton Haiti hot salt wells in the United States. Because this Gr.29 titanium alloy pipeline can reach more than 15 years and reduce the cost of maintenance, it is very economical to replace the application of thick steel and extruded Ti-38644/Pd tube in the geothermal industry. A Philippines company has also used pipeline in its high temperature (<330 C) and high acid (PH>2.3) geothermal water well. It has achieved remarkable benefits.

   In seawater desalination, the amount of titanium used in the desalination plant in the United States, Japan and China ,which has also increased significantly in recent years. A Japanese company built 3200 tons of titanium pipe for Saudi Arabia's seawater desalination plant. The amount used in desalination works in China's Tianjin and Shandong ,the sum is about 250 tons. Titanium in marine facilities ,it has also increased, and the large floating marine structures that have been or planned to use titanium have airports, port logistics bases, crude oil and natural gas storage bases, bridges, sports and entertainment facilities, etc.
