Effect of Alloying Elements on Welding Properties in Titanium and Titanium Tubes

Titanium has excellent corrosion resistance, various departments due to its excellent corrosion resistance, mechanical properties and process performance. In chemical production, titanium replaces stainless steel, nickel-based alloys and other rare metals as corrosion-resistant materials to increase output, improve product quality, extend equipment life, reduce energy consumption, reduce costs, prevent pollution, improve working conditions, and increase productivity. Has a very important meaning. The scope of titanium materials used in China's chemical industry is expanding, and consumption is increasing year by year. Titanium alloy standard parts have become one of the important anti-corrosion materials. As an anti-corrosion structural material used in chemical plants, titanium has attracted more and more attention from the engineering community.

1. Chlor-alkali industry

The chlor-alkali industry is an important raw material industry, and its production and development have a great impact on the national economy. The corrosion resistance of titanium alloy standard parts to chloride ions is better than that of commonly used stainless steel and other non-ferrous metals. At present, titanium alloy standard parts are widely used in the manufacture of metal anode electrolyzers, ion-exchange membrane electrolyzers, wet chlorine coolers, refined brine preheaters, dechlorination towers and chlorine cooling scrubbers. In the past, the main components of equipment were mostly non-metallic materials, with poor mechanical properties, thermal stability and processing performance, resulting in large equipment weight, high energy consumption, and short life span, affecting product quality and polluting the environment.

2. Soda ash industry

Alkali is one of the most basic chemical raw materials and is closely related to the development of the national economy. In the production process of soda ash, the gas medium is mostly NH3 and CO2. The main body of the carbonization tower tube, hot mother liquid cooler, cooler, crystallization external cooler, etc. is used for high-concentration solution, carbon drink, cast iron material for carbonation reaction. The equipment is not resistant to corrosion, has serious corrosion and leakage, and has a service life of no more than three years.

Titanium alloy standard parts are called "Future Metal" because of their light weight, high strength, strong heat resistance and corrosion resistance, and are a new type of structural material with development prospects. Titanium alloy standard parts not only have important applications in the aerospace field, but also have been widely used in chemical, petroleum, light industry, power generation and other industries.
