A pipe rack assembly uses hot-dip galvanized trusses joined together by screw connections. The welded were manufactured with ASTM A572 gr.50 W steel profiles. Two of them fractured during the galvanizing bath. fractures presented typical characteristics LMAC — liquid metal-assisted cracking mechanism. In both cases, fracture was located in structural element base metal and followed fillet weld ...

Ordinary steels have poor corrosion resistance in chloride medium leading to a deterioration of their longevity. The present research work focuses on the deposition and characterization zinc layer by dip galvanizing onto low carbon steel ASTM A283M-98 sheet form using different techniques such as optical microscopy, scanning electron microscopy (SEM) coupled energy dispersion spectrometer (EDS)...

A CFD model to simulate the cooling technique trough slot jet impingement has been developed. Such a tested on an existing vertical galvanizing industrial line, which initially envisaged round configuration, subject of previous work. Two different configurations have simulated and compared pre-existing one, in order provide design information for possible new cooler after exploring solutions. T...

Effective digital environmental communication is integral to galvanizing public support for conservation in the age of social media. Environmental advocates require messaging strategies suited media platforms, including ways identify, target, and mobilize distinct audiences. Here, we provide – best our knowledge first systematic characterization personas on Beginning with 1 million nongovernmen...
