Cladding of Pressure Vessel Steels for Coal Conversion Applications: A Literature Review

摘要

The available literature is reviewed concerning corrosion-resistant lining of large ferritic steel vessels and piping, applicable to coal gasification and liquefaction systems. Potential ferritic steel pressure vessel and piping materials are discussed along with potential stainless steel and nickel-base cladding materials. The various lining techniques currently used in the United States and abroad are also reviewed, with advantages and disadvantages of each. Materials problems with the various techniques are described. Several methods are available to produce ferritic steel components lined with corrosion-resistant layers. For low-temperature-low-thermal cycling applications, applied linings may be a good choice. However, for more critical applications, integral cladding is generally preferred. Integral cladding may be performed by a variety of methods, including solid state cladding, braze-bond cladding, and weld overlay (fusion) cladding. The lining process should be chosen after careful consideration of base metals and cladding metals desired and of the service requirements for the lined component. (ERA citation 04:000051)
