Abstract: | Economic use of corrosion-resistant materials in plant construction . Particular attention must be paid to choice of materials, constructional design, and production processes in order to achieve optimum, favourably priced solutions in the planning and construction of equipment for chemical plant. In the choice of materials, special stainless steels and non-ferrous metals of recent development, should be given special attention, particularly with respect to cost-saving substitution of expensive quality materials. The use of clad steel sheet fulfills requirements for optimum design of components for many applications; however, the economic use of these composite materials must be compared with that of solid materials from case of case – due attention being given to the strength and working properties of the materials. The lining of equipment with high-quality corrosion-resistant materials is also an economic production method but its limited applicability should be borne in mind. Welding is a cost-relevant production method. Use of welding techniques with high fusion rates, which is feasible for some high quality materials, can lead to considerable cost savings. Economic production of curved plates from Superferrit Remanit 4575 is possible by welding together individual rounds. |
