Steel industry erosion-corrosion

Table 1.29 tabulates most known examples of erosion corrosion problems occuring in aqueous systems. Historically, erosion corrosion first became a problem with the copper alloy (70%Cu 29%Zn l%Sn) condensers of naval shipsErosion corrosion of copper alloys has been an ongoing problem since then. The other major problem areas are (a) power plants where steels are exposed to water or water/steam mixtures in the temperature range 90°-280°C (b) the oil and gas industry where steels are exposed to various liquid, gas, and sometimes solids combinations containing carbon dioxide.

The austenitic cast irons are in widespread use in many industries (food, pharmaceutical, petroleum, chemical, petrochemical, pulp and paper, etc.) in mildly corrosive and erosive situations where the life of unalloyed or low-alloy cast iron or steel is short, but the high cost of stainless steel and nonferrous alloys cannot be justified. [Pg.60]

In the polyacrylic synthetic fibre industry, carbonitrided molybdenum guides have been used in place of chromium plated steel because of their resistance to corrosion and erosion. Chemicals that attack molybdenum are listed in Table 5.9. [Pg.849]

The outstanding property of rubber in general is resilience, or low modulus of elasticity. The flexibility and physical properties of rubber account for its application in general engineering and automobile industries whereas its chemical, wear and abrasion resistance as a sacrificial material, plus its insulating properties are utilised in many corrosion and erosion applications in process industries. Rubber lined mild steel, pipes and tankages have been standard materials of construction for hydrochloric acid service for many years. [Pg.10]

Early rotors were often manufactured of steel or brass, but now, they are more commonly constructed of aluminum and titanium (Table 2). Newer composite materials have made tremendous gains in popularity, with plastics for small-scale applications, and stainless steel for industrial-scale units in common use. Though somewhat more expensive, titanium is particularly suitable as it has both a higher strength-density ratio and a high resistance to corrosion and erosion. [Pg.498]

Duplex stainless steel Utilised in the oil, gas and petrochemical industry for critical equipment construction where erosion and corrosion resistance is required. However, it can be susceptible to galvanic and crevice corrosion effects. Manufacturing difficulties and repair capability, combined with high cost, limit the use of this material for large constructions. [Pg.86]

Titanium 2illoys are being used in increetsing quantities in the aerospace industry because of their high corrosion resistance. The reduction in the passivating films caused by particle erosion as observed in steiinless steel has been investigated for titanium and titanium alloys [2]. [Pg.274]
