The rational selection of the use of zirconium in acrylonitrile production is stated. Equipment design, manufacture, inspection and test conform to NB/T 47011 2010 Zirconium Pressure Vessel. Since working conditions in the sulfuric acid and other working conditions of the different forms, the structure of pipe connecting to equipment uses ride sitting, cover plate uses Ω type of plate. Through actual use, proven zirconium used in the sulfuric acid storage tank, the reliability of such conditions for the use of zirconium to provide a realistic basis.

Tantalum has excellent corrosion resistance against strong sulfuric acid in high temperature, hydrochloric acid and other corrosive media. Taking into account the economy, in general tantalum, tantalum coil thin-walled pipe manufacturing, due to its low strength and stiffness, forming process variability, size is not easy to control. Using a three-roll coil forming device processing technology can guarantee its good surface quality, roundness, dimensional tolerances, etc., it is a more reasonable tantalum coil processing. © 2016, Petrochemical Equipment.
