Erosion-corrosion chemical plant

Water which is used for cooling purposes in refineries and chemical plant can cause severe problems of corrosion and erosion. Ordinary cast irons usually fail in this type of environment due to graphitic corrosion or corrosion/ erosion. Ni-Resist irons however show better corrosion resistance, due to the nobility of the austenitic matrix, and are preferred for use in the more aggressive environments such as those containing appreciable amounts of carbon dioxide or polluted with chemical wastes or sea-water. 

Often certain pipes in chemical plants must be replaced because of corrosion and erosion. Table 13-P2 gives the costs and times of the activities which are involved in... 

The effects of corrosion and erosion must be considered in the design of chemical plants and equipment. Chemical resistance and physical properties of constructional materials, therefore, are important factors in the choice and design of equipment. The materials of construction may be resistant to the... 

Piping systems may be relatively simple or complex and may convey utility services and chemical fluids that can be highly flammable, highly toxic, corrosive, erosive, or any combination of these properties. Piping systems within chemical plants handling hazardous Iluids must be designed, fabricated, tested, operated, and maintained consid-...
