The 9%Ni steel was recently used for the first time on the field in the injection unit (IU) for the injection of CO2 into oil wells. Because such steels are operated in H2S medium and are susceptible to sulfide stress cracking, their pipes are cladded with Nibased&#x...

GTAW-HW (Hot Wire Gas Tungsten Arc Welding) cladding process is widely used in the offshore industry, despite its low deposition rate and greater difficulty to control the level of dilution. The Plasma Powder Transferred Arc Welding (PPTAW) process is an alternative for internal cl...

In a mineral deposit, ore are known with variable characteristics, which affects the processing stages of the manufacturing in terms of their efficiency and productivity. The present work was designed to investigate the variability in comminution stage of different iron ore typologies f...

In this study some numeric technics were evaluated for the calculation of elastoplastic fracture mechanics parameter 𝐽 integral on pre-cracked flanged connections using finite element analysis. Resistance curves to the crack propagation were evaluated experimentally at room temperature (23°C) in ...
