Pressure vessels are widely used pressure equipment in production and life. They can be divided into many kinds according to their materials. In the production and processing process of relevant inorganic chemical industries, glass pressure vessels have good anti-corrosion performance, but they have the disadvantages of easy crushing of collision machinery and cracking due to sudden cooling and heat. Tantalum clad pressure vessels can perfectly overcome the above shortcomings, However, the price is relatively expensive, and such metal raw materials will be used only in important equipment. Let me introduce the performance and design principle of the tantalum-clad pressure vessel.

Performance of tantalum clad pressure vessel

Tantalum material has excellent corrosion resistance in most inorganic acids, can resist the corrosion of almost all chemical media, and has excellent properties such as good ductility, high thermal conductivity, and good chemical stability. Tantalum material is expensive, and its application forms are mainly composite plates and lining. However, the welding between composite plate and lining is very difficult, which is caused by the wide difference in melting point between tantalum material and steel. The melting point of tantalum metal is 2996 ℃ and that of steel is 1400 ℃. Therefore, tantalum clad pressure vessel is more common in the actual production process.

Design principle of tantalum clad pressure vessel

In the expansion joint between tantalum heat exchange tube and steel pipe plate in tantalum clad pressure vessel, the reduction of expansion supporting force caused by the difference of thermal expansion coefficient after temperature rise is considered. In the tantalum lined shell, the reduction of tight fit caused by different linear expansion coefficients of the substrate and the lining is considered. If necessary, a waveform structure can be set to absorb the expansion.

Leak detection structure of tantalum clad pressure vessel

Tantalum clad pressure vessel considers and sets a leak detection structure, which can not only check the welding quality of welded joints but also check whether the lining is damaged during the operation of tantalum clad pressure vessel. To quickly find the damaged part of the lining in the process of leak detection, the container separates the leak detection channels on the longitudinal circumferential seam, sets a separate leak detection structure on each channel, sets more than 2 leak detection structures for the longer channel, and sets the position below the gravity as far as possible, to improve the leak detection efficiency.

Tantalum clad pressure vessel produced by Nanjing Suntech Metal Equipment Co., Ltd.has the advantages of reliable quality, high quality and low price, energy conservation, and environmental protection in the production and processing field related to inorganic chemistry. At the same time, it has a sensitive leak detection system and has carried out a large number of tests before leaving the factory to ensure quality. Therefore, it is favored by users in the inorganic chemical processing industry.
