Short Introduction
Because titanium tube has excellent corrosion resistance, mechanical properties and process properties, titanium tube have been widely used in chemical industry as an excellent corrosion resistant structural material.
1.Introduction of titanium welded tube for chemical
Because titanium tube has excellent corrosion resistance, mechanical properties and process properties, titanium tube have been widely used in chemical production as an excellent corrosion resistant structural material. Especially in chemical production, titanium is used instead of stainless steel, nickel-based alloys and other rare metals as corrosion-resistant materials. This is of great significance for increasing production, improving product quality, extending equipment life, reducing consumption, reducing energy consumption, reducing costs, preventing pollution, improving labor conditions, and increasing labor productivity.

5.Why choose titanium welded tube for chemical
Because titanium tube has excellent corrosion resistance, mechanical properties and process properties, it is widely used in the chemical industry. Especially in chemical production, titanium is used instead of stainless steel, nickel-based alloys and other rare metals as corrosion-resistant materials. This is of great significance for increasing production, improving product quality, extending equipment life, reducing consumption, reducing energy consumption, reducing costs, preventing pollution, improving labor conditions, and increasing labor productivity.
6.Application of titanium welded tube for chemical
At present, the application of titanium equipment has expanded from the original "soda and caustic soda industries" to chlorate, ammonium chloride, urea, organic synthesis, dyes, inorganic salts, pesticides, synthetic fibers, fertilizers, and fine chemicals industries It has developed from small and singular to large and diverse. The Ministry of Chemical Industry estimates that the amount of titanium used in the chemical industry will exceed 1,500 tons. At present, the largest number of domestic chemical titanium equipment are heat exchangers, followed by titanium anodes and vessels. The survey results show that titanium heat exchangers account for 56.66%, titanium anodes account for 20.41%, titanium vessels account for 16.28%, and other ones account for 6.65%.
