Protection from material failures
The oil, gas and mining industries use Metal Improvement Company’s (MIC) processes to control wear; provide damage tolerance and galling resistance and provide solutions for stress corrosion cracking (SSC) and fatigue particularly in harsh and hostile environments.
Applications
- Control Valves – all types, including ball, angle, gate and plug
- Turbine Blades, vanes and stators
- Piping – straights, tees, elbows and reducers
- Gearboxes – contacting surfaces
- Seals, tubes, wear pads, rings
- Pistons, shafts, bushings, gears, clutches
Shot Peening
Shot Peening can be applied to welded joints and other metallic components to reduce or eliminate SCC replacing the tensile stress on the surface with beneficial compressive stress.
Engineered Coatings
MIC is also a leading applicator of engineered coatings that solve the problems caused by the aggressive environments in which pumps and valves operate.
Our coatings address service conditions including wear, corrosion, erosion, seizing, steam and extreme temperatures (-420 °F to 1800 °F/-251 °C to 982 °C), as well as applicable aesthetic standards.
Case Study
A Norwegian research program concluded that the combination of weld toe grinding and shot peening gave the largest improvement in the life of an offshore steel structure. This corresponds to more than a 100% increase in the as-welded strength at one million cycles. Other research shows that the improvement in weld fatigue strength from shot peening increases in proportion to the yield strength of the parent metal.
