Overview of titanium pipes Titanium and titanium alloy pipes are new structural materials. Because titanium has high melting point, small specific gravity, high specific strength, good toughness, fatigue resistance, acid and alkali corrosion resistance, low thermal conductivity, and good high and low temperature resistance , The characteristics of low stress under the conditions of rapid cold and rapid heat. It is used in chemical heat exchange equipment and is continuously promoted to industries such as petroleum, electric power, desalination, construction, and daily necessities.
