Commonly - used Grades and Uses of Titanium Tubes

When it comes to metal pipes, many people think of titanium tubes. Indeed, titanium tubes are widely used in our daily lives. However, many people still don't know much about titanium tubes. It doesn't matter. I'm going to tell you about the commonly - used grades, implementation standards, and uses of titanium tubes today. 

First of all, let's talk about what a titanium tube is. Titanium and titanium alloy pipes are new - type structural materials. Because titanium has characteristics such as high melting point, low specific gravity, high specific strength, good toughness, anti - fatigue, resistance to acid - base corrosion, low thermal conductivity coefficient, good tolerance to high and low temperatures, and low stress under rapid cooling and heating conditions, it is used in chemical heat - exchange equipment and is constantly being promoted to industries such as petroleum, electric power, seawater desalination, construction, and daily necessities. In general, titanium tubes have been widely used in seawater desalination, petroleum, chemical, mechanical equipment, nuclear power equipment, electric power equipment, automobile and motorcycle components, sports and leisure, medical components, iron and steel and metallurgy, high - and - new technology and other fields, playing a huge and important role. 

There are mainly two types of commonly - used grades of titanium tubes: national standard grades and American standard grades. The national standard grades include TA1, TA2, TA9, TA10, and TC4, while the American standard grades include GR1, GR2, GR7, GR12, and GR5. 

As for the commonly - used implementation standards of titanium tubes, they are also divided into national standards and American standards. The national standards include GB/T 2924 - 2007 and GB/T 3625 - 2007, while the American standards include ASTM B337 and ASTM B338. 

The reference standards for titanium tubes are GB 228 (Metallic Tensile Testing Method); GB/T 3620.1 (Grades and Chemical Compositions of Titanium and Titanium Alloys); GB/T 3620.2 (Chemical Compositions and Allowable Deviations of Processed Products of Titanium and Titanium Alloys); GB 4698 (Chemical Analysis Methods of Titanium Sponge, Titanium and Titanium Alloys). 

Of course, titanium tubes also have some technical requirements. For example, the chemical composition of titanium and titanium alloy bars should comply with the provisions of GB/T 3620.1. When repeated verification is required, the allowable deviations of the chemical composition should comply with the provisions of GB/T 3620.2. In addition, there is GB/T 12969 (Ultrasonic and Eddy - current Testing Methods for Titanium and Titanium Alloy Pipes).
