Experience in Welding of Extra Pure Hydrogen Filters and Catalytic Reactors Design
It is considered welding experience in filters for extra pure hydrogen purification (EPHy)producing and catalytic reactors design in the former USSR. It is shown that microplasma welding of them has some advantages as compared with alternative welding methods and brazing. In the majority cases such devices made of very thin palladium-based foils are mare perspective than made of thin tubes of the similar materials. In order to obtain the best quality of welded joints many research and investigations have been made, and they permited to avoid porosity, cracks and some other defects in welds. At the same time another problem was solved──what constructional materials are suitable for filtering elements (FE) and how to weld them to very thin palladium foils. In cooperation with many orgauizations the Paton Welding Institute developed various original welded FE structures that were introduced to some plants and gave positive results in their exploitation. It is a pity that due to the former USSR collapse this work has not been fmished, but the obtained experience can be used by followers of this important field in the modem technologies development. It may permit to improve quality of chemical, metallurgical, pipe, electronic, food, pharmaceutical and other branches of industries. Our unique results of All welded extra pure hydrogen FE and catalytic reactors creating also opens good perspectives for hydrogen energetics and economy development, design improved fuel elements, catslityc reactors, producing high pure hydrogen isotopes, etc.
