Tantalum clad pressure vessel refers to closed equipment containing gas or liquid and bearing a certain pressure. At the same time, tantalum metal is covered on the surface of the equipment. It is a kind of equipment with a wide range of applications. There is no lack of pressure vessel products in petrochemical, energy, scientific research, military industry, and other fields. Tantalum clad pressure vessel is widely used in inorganic chemistry-related industries. Let me introduce the relevant information of the tantalum-clad pressure vessel in detail.

Classification of tantalum clad pressure vessel

The service fields of the tantalum-clad pressure vessel are four categories, namely chemical industry and petrochemical industry, oil refining, electric power, and alternative energy (nuclear power and coal gasification and liquefaction), among which petrochemical industry with energy as raw material accounts for the largest proportion. The demand for a tantalum-clad pressure vessel is also increasing rapidly in the other three major sectors directly belonging to the energy industry. According to the active principle of tantalum clad pressure vessel in the production process, it can be divided into four types: reaction vessel, heat exchanger, separation vessel, and storage and transport vessel.

Application background of tantalum clad pressure vessel

Because tantalum has a low content in nature and high melting energy consumption, it is expensive. Therefore, tantalum metal is generally used when other metals are difficult to replace. Tantalum clad pressure vessel is mainly used in the production processes of strong acids (hydrochloric acid, sulfuric acid, and nitric acid), hydrogen peroxide, bromine, chlorine, and petroleum industry. Its main application forms include pressure vessels such as reactors and heat exchangers, Because the direct use of tantalum in the manufacture of pressure vessels is huge and easy to waste resources, tantalum plating on the surface of pressure vessels is mainly used.

Process key points of tantalum clad pressure vessel

Tantalum is sensitive to impurity immersion, so it is required in a welding environment. When heated to 300 ℃, hydrogen, oxygen, nitrogen and other gases in the air react violently with tantalum to form brittle compounds; At the same time, tantalum will react with silicon, carbon, and boron to form brittle compounds, which reduce its plasticity and toughness. Therefore, the welding environment of the tantalum-clad pressure vessels must be controlled. In addition, due to the difference of thermal expansion coefficient between tantalum heat exchange tube and tube sheet after the temperature rise, it is easy to reduce the pull-out force of the expansion joint. During welding, it must be considered to protect the inert gas channel on the back of the welded joint. The welding site of the tantalum-clad pressure vessel should keep the air clean, dust-free, and smoke-free.
