In recent years, due to the special requirements of the working environment of some large chemical enterprises, tantalum, rare metal material that can withstand high temperature and corrosion-resistant environment, has gradually entered people's attention. In the production and processing industry related to the fine chemical industry, tantalum pipe has many properties such as excellent corrosion resistance and ductility, More and more people began to use it in the fine chemical industry. Let me introduce the application background and characteristics of tantalum pipe.

Here is the content list:

• Welding process of tantalum pipe

Application background of tantalum pipe

The melting point of the tantalum pipe is 2996 ℃, and the density is 16.68 g / cm. Because of its high melting point, corrosion resistance, and good cold working performance, tantalum tubes, and tantalum tungsten alloy tubes are widely used in the fine chemical industry, high-temperature technology, and atomic energy industry. Tantalum pipe and tantalum tungsten alloy pipes are mainly used to manufacture reaction vessels, heat exchangers, pipes, condensers, bayonet heaters, spiral coils, U-tubes, thermocouples, and their protective tubes, liquid metal containers, and pipes in chemical processes.

Characteristics of tantalum pipe

Tantalum pipe is used in fine chemical equipment with its excellent corrosion resistance in some extremely harsh corrosive environments. In addition to hydrofluoric acid and caustic soda, it is completely inert to most chemical products. Tantalum pipe is resistant to the corrosion of various concentrations of acidic substances below the boiling point, oxidizing metal chlorides, organic acids, and other media. It is known as the metal with the best corrosion resistance. Tantalum pipe has strong chemical activity, especially in the welding process, the gettering of molten tantalum is relatively strong. The compound produced by it will rapidly reduce the plasticity and brittleness of welded joints, and reduce the corrosion resistance to high temperature and high pressure.

Welding process of tantalum pipe

Tantalum pipe has good mechanical properties, but because of its slightly high price, it is usually used in the form of composite plate and lining. The seamless tantalum pipe is used as the heat exchange pipe and the tantalum steel composite plate is the representative of the application of tantalum pipe in the fine chemical industry. The technology of tube plate welding is one of the key technologies. The welding quality of the welded joint of the tube plate has an important influence on the quality of the machine. Generally, the welding of tantalum steel clad plates is very difficult. In order to reduce the manufacturing cost, the reduction of cladding thickness will greatly increase the difficulty of welding. If the welding measures are improper, it is very easy to cause weld cracking.

Tantalum pipe is more and more widely used in fine chemical-related industries and is more and more loved by customers. The tantalum pipe developed and produced by Nanjing Suntech Metal Equipment Co., Ltd. has been widely praised by customers in the industry after many technical inspections and quality tests.
