Whether titanium welded pipe can be used at low temperature

As a rare metal element, the performance of titanium far exceeds what we have seen-power generation equipment, especially its low thermal cycle temperature, provides an ideal use scenario for titanium. It is possible to develop a new type of titanium tube for use at higher temperatures. Compared with the developed high-strength low-temperature titanium tube, it has greater potential in saving metal and improving efficiency. The goal for the future is to develop a titanium tube that can be used at temperatures up to 650°C compared to the commonly used base turntable, an alloy that can be used in high-pressure turbine turntables and can reduce weight by 20%.

With the increase of working temperature, it will bring more new problems, such as surface oxidation, stability of long-term large-scale metallurgical production, friction corrosion, fire hazard and hot salt intergranular corrosion. Some problems can be solved by surface coating or surface treatment, so research in this area is currently being actively carried out.

Titanium tubes are produced by automatic continuous production lines such as cold bending, welding, online heat treatment, diameter straightening, non-destructive testing, and air tightness testing. With the rapid development of the titanium industry and the increasing improvement of the welding process, the production efficiency of titanium pipes will be greatly improved, and the quality stability, consistency and production efficiency will be greater. The length required for cutting can be determined according to customer requirements.

Titanium tubes are generally produced by rolling or drawing an art. A large amount of rolling oil and drawing oil will be used in the production process, which will seriously pollute the production site. After the titanium tube is rolled and drawn, the grease and stains on the inner and outer surfaces of the goods must be deoiled and pickled. The pickling process will cause great pollution to the environment.

For the health of operators and environmental protection, protective equipment and measures should be added, and then capital investment should be increased, and the production cost of goods should be increased accordingly. Titanium tubes continue to be mass-produced through automated production lines, with stable quality and high production efficiency. In the production process, except for some water, electricity and other energy consumption, the environment is basically free of pollution.
