The application of desalination titanium tubes is a major trend

The global water resource crisis is becoming increasingly severe, and seawater desalination is recognized as one of the best solutions to the freshwater crisis. Currently, seawater desalination has been implemented in over 120 countries and regions worldwide, with approximately 13,000 seawater desalination plants. The daily output of seawater desalination is around 35 million tons, and it is increasing at a rate of over 10% annually. Seawater desalination has become one of the best methods for addressing water scarcity issues.

The main mainstream methods of seawater desalination currently include multi-stage flash evaporation (MSF), low-temperature multi-effect distillation (LT-MED), and reverse osmosis (RO) membranes. Each method has its own advantages and disadvantages, and the applicable conditions and scopes are also different. In China, LT-MED and RO methods are mainly applied. In the coming years, several seawater desalination projects will be launched.

In the next 5-10 years, there will be significant development potential for seawater desalination in China. China's seawater desalination technology has matured after 40 years of research, with equipment costs reduced by 30%-50% compared to abroad, and the cost per ton of water has approached the international advanced level. Large-scale application of seawater desalination has achieved cost advantages, and compared to the South-to-North Water Diversion Project, the cost per ton of water is lower. The country has introduced a series of encouraging policies, and the scale of seawater desalination in the next 10 years will be five times that of the present.

The use of titanium alloys instead of copper alloys in seawater desalination equipment is the future trend. The multi-faceted advantages of titanium materials determine the extensive application space in the field of seawater desalination pipes in the future. It is expected that in the next ten years, China's demand for titanium in seawater desalination will be approximately 9,500-23,520 tons, and globally it will be about 14,063-28,125 million tons. Although the initial estimated demand in China is not large, domestic demand only accounts for 1.6% of the total international demand, so the overall development space is very huge.
